Posted July 3, 2017 (Atlanta, GA)  The ViVitro SuperPump and 3-D printing technologies are part of ground breaking research being conducted by researchers at Georgia Institute of Technology and the Piedmont Heart Institute. Heart valve models created with advanced 3-D printers could soon assist cardiologists in preparing to perform life-saving heart valve replacements.

Researchers at Georgia Institute of Technology and the Piedmont Heart Institute are using standard medical imaging and new 3-D printing technologies to create patient-specific heart valve models that mimic the physiological qualities of the real valves. Their aim is to improve the success rate of transcatheter aortic valve replacements (TAVR) by picking the right prosthetic and avoiding a common complication known as paravalvular leakage.

“Paravalvular leakage is an extremely important indicator in how well the patient will do long term with their new valve,” said Zhen Qian, chief of Cardiovascular Imaging Research at Piedmont Heart Institute, which is part of Piedmont Healthcare. “The idea was, now that we can make a patient-specific model with this tissue-mimicking 3-D printing technology, we can test how the prosthetic valves interact with the 3-D printed models to learn whether we can predict leakage.”

The researchers, whose study was published July 3 in the journal JACC: Cardiovascular Imaging, found that the models, created from CT scans of the patients’ hearts, behaved so similarly to the real ones that they could reliably predict the leakage.

In vitro testing in the age of transcatheter therapies

Posted on

Share on FacebookTweet about this on TwitterShare on LinkedIn

By Rob Fraser

Advances in medical imaging modalities have allowed health care providers to offer a wide range of minimally invasive interventions which are implanted via catheters. Patients benefit tremendously from the minimally invasive nature of these options, which have caused an explosion of new devices to come under development. Patients are now demanding transcatheter approaches (albeit in the authors opinion perhaps too prematurely) which is putting pressure on traditional treatments. Like most disruptive technologies many peripheral industries are impacted when a new way of doing things becomes the norm. At ViVitro we specialize in conducting in vitro testing for a wide range of cardiovascular devices, and these advances in medical imaging have had a profound impact on our industry as well.

20 years ago if you wanted information on how a new cardiovascular device would perform, your main source of data would be in vitro testing, however now medical device companies are able to gain insights about their device from animal models that were not possible only a few decades ago. As a result, there is a new generation of device developers who have done much of their development purely in animal models. Ethical concerns aside, there are benefits to an animal focused approach since many devices require native anatomy that is challenging to re-create in a bench top setting. There are numerous reasons why there will always be a place for in vitro testing, but ones I find often overlooked are:

Durability Testing

Cardiovascular devices are typically placed around a beating heart or in a pulsatile flow environment. As a result cyclic loading is always applied to these devices creating the risk of a potential failure mechanism. Computational models can be useful in designing for fatigue but before a device is ever implanted in a patient, it must go through physical life cycle testing. The fastest way to get these results is to accelerate them in a laboratory setting, something impossible to do with animals. At ViVitro we are able to put a device through millions of cycles in a single day, something that would take almost a month in an animal.

Many clients have durability testing on their long list of things to accomplish before they call their design “finished” but my observation is that this is often left until too late in the design process. Clients will come with what they feel is a finalized design and are simply looking to check the durability box on their device submission only to find too late that they have a serious design flaw. At ViVitro we understand the motives behind this, durability tests can be lengthy and are perceived as expensive undertakings. For that reason we offer a range of service options to make it possible for companies to put prototypes through their paces early in the design process, preventing costly surprises when the finish line looks to be in sight.

Controlled Environment

As mentioned earlier animal testing has huge benefits including being able to test numerous different aspects of a device with a single animal. In addition to device hydrodynamic performance, data on biocompatibility, hemolysis, migration, etc can be examined at one time. While this is extremely useful, and cost effective for start-ups, it can also be very frustrating when things go wrong. If a problem is identified, the root cause ascertained, a solution implemented often the most conclusive way of determining if a device iteration will be a success is to conduct a controlled in vitro test. With the exception of mandatory testing requirements to validate a design for regulatory approval, many clients come to us looking to test a specific change in their device design.

In doing so many people familiar with animal models will approach a single test in the same multifaceted way their approach an animal study. The beauty of bench top testing is to simplify the problem down to a set of variables which can be controlled or altered in an exacting manner. At ViVitro our equipment makes this task a breeze, and we often create customization for clients interested in testing a unique aspect of their design. We also have a history of creating test protocols used in numerous different cardiac devices

In summary, advances in medical imaging have created a new generation of transcatheter medical devices. These devices revolutionize treatment for patients and are causing disruptions in many industries including ours. The imaging advances allow designers gain huge insights from animal models, which were previously the sole domain of bench top testing. For those clients new to in vitro testing I would recommend:

1) Test early – Contact an in vitro service or equipment vendor early in the design process to understand how they can help at all stages of your design. This will accelerate your design process and prevent costly late stage design stages

2) Simplify – Bench top testing allows designers to simplify a complex system down a bare minim of components to understand individual aspects of a device design. At ViVitro we are experts at justifying the simplifications necessary to test different aspects of a device design.

INTERVIEW: Yuewei (Shining) Sun discusses Chinese cardiovascular device market

Yuewei (Shining) Sun

Yuewei (Shining) Sun

 

Yuewei (Shining) Sun is the manager at Fortis Hi-Tech, ViVitro’s sales representative in China.  Sun visited ViVitro in early January for a week of extensive training.  During a break, he talked with ViVitro Labs (VL) about the unique attributes of the Chinese market, Fortis-Tech, and plans for the future.

VL: Tell us about your background and what you do at Fortis Hi-Tech:

YS: After graduating from university with a degree in mechanical engineering, I worked in automation – hydraulics and pneumatics of the motor.  After a few years in this field I switched to fluid transmission – especially for automobiles. Specifically a sealant and adhesive dispenser system.

Our main business at Fortis is service and engineering. We have six employees and two assist me with hardware support for ViVitro equipment.  Prior to working with ViVitro we were looking at areas to expand beyond automotive applications because the area is quite competitive in China and it is very hard to be unique. We wanted to have a new company to do creative things. A friend in the medical device industry suggested we consider medical equipment because it is growing very fast in China. I researched the equipment market, and while studying stents, I noticed heart valve products and learned about ViVitro.

My friend said that ViVitro is a very good company and there were customers in China that I could contact for more information.  I spoke with them and they were very interested in ViVitro products. I contacted David Mester (ViVitro GM at the time) about selling products in China. Fortunately, David agreed I could be the distributor in China. When I visited the team in Victoria, I knew I had made a good decision.

Five years later, under Gerry Wight’s management, ViVitro communicates a lot more, holds a seminar in China every year and visits our customers at least once a year with me.

VL: What was it like to sell cardiovascular device test equipment in China five years ago?

YS: Five years ago there were only 2-3 manufacturers in China and the testing center was still using an old standard.  The manufacturers were studying and trying to find a new supplier, not just for the testing equipment but for the testing methodology. Initially I would simply supply equipment, translate information provided by ViVitro, and transfer it to customers because I had no background in cardiovascular testing.

In the beginning this worked because the ISO standards that applied in China were minimal compared to today, so companies didn’t need further service or consulting. Even today, the ISO standards used are not the latest available. While the industry still lags behind North America and Europe, they require much more information than five years ago.

VL: Do you plan to expand into cardiovascular testing services?

YS: We are currently working with customers to build system parts. I want to expand the Fortis business by making simple custom equipment (small accessories compared to the ViVitro equipment) for universities and institutes.  For example, a steady flow device that provides an overview of the flow, but not specific measurements.  It would be suitable for teaching and early research and development, but not for regulatory purposes.

 

VL: What’s unique about the Chinese market?

YS: For me there are two differences. When we started working with cardiovascular devices, we got our knowledge from US and Canada.  In the beginning, we didn’t develop, we just followed.  Now, more and more investors are investing in China because it is big.  We can do more independent research with data from China for devices made for Chinese people.  In the beginning, the difference was that we were not a developer, but a follower.

The second difference is the construction of the patient.  We have a different heart disease focus in China.  We have a very big market for one kind of product that is smaller in the US. In the US, heart valves are mainly for elderly patients.  In China, because there are patient differences or the treatments are different, more younger people need heart valve surgery.  They have different requirements for these kinds of devices.

Traditional Chinese medicine uses needles and other physical treatments to keep the body balanced long term.  For a big disease, western medicine works right away, but it doesn’t care about afterwards or about long term– things like maybe you should adjust your body to be as far as possible from displaying visible signs of disease.  Chinese medicine cares about keeping all of your organs balanced together. Not, if you liver is diseased, you just work on the liver.  No, we want all of the organs and all of the body to work together.

If you have a very serious disease in China, they normally have two ways; one is to use western medicine to control the disease because it really works, and at the same time they take Chinese medicine to adapt the whole body for the long term suitability against the disease. We normally use both ways.  But we think the western medicine is so strong it may cause other problems you cannot see.  Chinese medicine is more subtle and can cure your disease very peacefully.

VL: Does it work? Have they done any tests?

YS: No. Chinese medicine is hard to prove.  We use different plants as natural medicine which have poison inside.  We cannot prove that this is totally suitable for a specific disease or is not harmful to the body.  Even now, these medicines are only available in China and Asia. We believe the treatment is better although it is a little hard to prove. Lots of work remains to prove the results in a way similar to western testing.

VL: What are the opportunities and challenges for cardiovascular devices in China?

YS: The market is growing very, very fast in China.  Initially, only a big company would be interested in cardiovascular devices, but now more and more mid-sized companies are becoming involved.  The market is not as interested in the equipment itself, but in the chance to obtain more details for their testing or the design they are developing. That means the basics are fine now, but they seek more professional equipment, accessories, service and consulting.  That’s our opportunity and our challenge. The opportunity is they ask for more.  The challenge is that Fortis should know more.  That’s why I’m here for more information to satisfy our customers.  Fortunately, the Chinese market is quite new to this area, ViVitro is the leader, and I can get the top training from ViVitro experts. Together we grow to serve our clients.  I look forward to continuing my personal training so I can better serve my customers in China.

VL: Is the market mainly about the domestic market or creating devices for other countries?

YS: Since last year, the big manufacturers in China have begun to acquire foreign companies and develop the global market. Microport is an example. Previously they focused on the market in China. Now they try to meet standards and marks for CE in order to export to Europe or other countries.

VL: Any advice for cardiovascular researchers in China?

YS: For me the main problem is time. The market is changing very fast.  If you have a good idea, you should act very fast to follow the changing market.  If not, you’ll lose the opportunity. Universities and institutes are trying to do more research in China.  In the future we will conduct Chinese research and testing so we can use all of the data from China. We are conducting research now and I hope that soon we will make devices just for China.

 


ViVitro Analysis: Impact of FDA Program Alignment

Share on FacebookTweet about this on TwitterShare on LinkedIn

By Vesna Janic, Director, ViVitro Labs QA/RA

The FDA reorganization announced a while ago seems to be finally shaping up this year.  The main goal of the Program Alignment is to better coordinate field inspections with product reviews from FDA research centers and to identify companies that need more frequent inspections based on the poor state of their quality.  In today’s global market, and due to limited FDA resources, the hope is that more risk-based inspection planning and collaboration with foreign agencies will eliminate duplicate inspections and make compliant manufacturers’ lives a bit easier through less frequent visits as a reward for exceeding QMS requirements and running high quality operations.

Logistically, under the Program Alignment plan the 5 regional Offices of Regulatory Affairs (ORA) will be dissolved and replaced with commodity-based and vertically integrated inspection programs for drugs, biologics, medical devices, tobacco products, food and bioresearch monitoring that will operate from 20 FDA district offices. Commodity-based teams will have specialized investigators with technical expertise and adequate training in their field of expertise.  For medical device companies, this means they will be inspected by investigators who are not only  specialized in medical devices with in-depth knowledge of Quality System Regulation (QSR) and the intricacies of manufacturing devices, but the investigators will also have a sub- specialty in their particular product.  This will have huge impact on the quality of an FDA inspection compared to the previous practice where a company could be inspected by an investigator with a background in food, tobacco or pharmaceutical products.

As with any change, the question remains if the FDA will be less effective initially while figuring out how to align 5000 FDA investigators into different review programs while developing new inspection protocols. 2017 may be tough for both the agency and inspected facilities, however my belief is that all manufacturers in good standing with the agency will benefit from less frequent inspections and will enjoy working with investigators that are specialized in their commodity. This new approach should positively impact product quality and patient safety.
