Insertion / Retraction Force
Uses both the proximal and distal load cell to measure the amount of force applied on the device and a specific accessory during retraction.
The IDTE 1000 proximal load cell is used to monitor the force applied at the proximal end of the device system and an auxiliary load cell to measure the force applied on a specific accessory during retraction or insertion. Boht the proximal and the forces on the auxiliary load cell as well as the advancement distance, are recorded simultaneously. Proximal forces and auxiliary loads are recorded simultaneously. The test fluid is circulated inside the anatomical model at a regulated at test temperature ±2°C. The devices are inspected visually, and any damage is recorded.
ViVitro uses the Interventional Device Testing Equipment (IDTE) 1000 to provide quantitative performance evaluation of interventional devices during simulated use testing. This test is conducted by advancing a device in a pre-defined anatomical vascular model to simulate the passage of devices during interventional procedures. Standard or specific anatomical 2D and 3D models can be used to simulate device insertion, tracking, deployment and retrieval.
The device is advanced and retracted automatically by the roller system which removes bias due to operator interactions. The IDTE proximal roller system measures advancement forces along the path and the auxillary load cells can be placed in various locations to measure distal forces on the device or resulting forces on interventional accessories. The IDTE roller system can handle infinite length catheter and a continuous advancement of the device during testing. No repositioning of the head is necessary. The IDTE equipment is PC controlled with numerous options for advancement profiles. Testing results can be used for regulatory submissions, competitive product evaluation and product development.
