TRANSCATHETER PROSTHETIC HEART VALVE DELIVERY SYSTEM WITH CLINICIAN FEEDBACK

摘要

A delivery system (20) for implanting a prosthetic heart valve (30) at a target site. The delivery system includes a delivery device (22) and at least one feedback sensor (24). The delivery device includes a delivery sheath (32) and an inner shaft. The inner shaft is coaxially received within the delivery sheath and includes a valve retainer (36) configured for temporary connection to the prosthetic valve in a loaded state. The delivery sheath contains the prosthetic valve (100) in the loaded state. The feedback sensor is adapted to sense a parameter implicating a delivery procedure characteristic, such as implicate a spatial relationship of the prosthetic valve relative to the delivery sheath or the target site, or of an interface between the sheath and the prosthetic valve. In some embodiments, the system further includes a user interface for conveying the feedback information to a clinician such as a touch screen.
