Development and ex vivo validation of novel force-sensing neochordae for measuring chordae tendineae tension in the mitral valve apparatus using optical fibers with embedded Bragg gratings

Few technologies exist that can provide quantitative data on forces within the mitral valve apparatus... Using FBG sensors, we created a force-sensing neochord that mimics the natural shape and movement of native chordae.... … Redwood City, CA, USA) was mounted to a programmable pulsatile linear piston pump (ViVitro Superpump, ViVitro Labs, Victoria, BC, Canada) with the ability to generate physiologic conditions using the pump controller and …
