GUIDED DELIVERY OF PROSTHETIC VALVE

摘要

An image-guided prosthetic valve deployment system employs a prosthetic valve (80), a catheter (70) and a delivery tracking system (90). The catheter (70) has an elongated body with a proximal tip (71a) and a distal tip (71b), and the elongated body includes a delivery section (72) adjacent the distal tip (71b) for deploying the prosthetic valve (80) relative to a heart valve (21) within an anatomical region (20). The delivery section (72) includes a delivery segment (73) for sensing a shape and an orientation of the delivery section (72) within the anatomical region (20) relative to a reference point (74). The delivery tracking system (90) tracks a position and an orientation of the prosthetic valve (80) relative to the heart valve (21) as a function of a sensed shape and a sensed orientation of the delivery section (72) within the anatomical region (20) relative to the reference point (74) by the delivery segment (73).
