Abstract
Fiber Bragg grating (FBG) sensors are used to provide measurement of chordae tendineae forces. Two basic modes of operation are considered, The first mode is a research mode, where the FBG sensors are affixed to native chordae in situ and preferably in vivo to provide data on chordae forces in a beating heart under various conditions (e.g., normal, hypertensive, etc.), The second mode is a clinical mode, where the FBG sensor can be used to measure tension on a prosthetic neochord during the surgical procedure to implant the prosthesis.
