摘要:
A sensing device for a collapsible prosthetic heart valve, the sensing device including an elongated shaft having a proximal end and a distal end, a sensing body coupled to the distal end of the shaft, the sensing body being adapted to fit within a native valve annulus and at least one microelectromechanical sensor attached to the sensing body, the at least one sensing body being capable of measuring a property of tissue.
摘要:
A valve holder is connectable to a prosthetic valve including a stent having a plurality of commissure posts. The valve includes a base, a plurality of legs extending from the base, and one of several mechanisms for deflecting the plurality of commissure posts radially inward so as to temporarily decrease the overall size of the prosthetic valve.
摘要:
An implantable device system includes an implantable device (1102), such as an annuloplasty ring, for controlling at least a shape and/or size of a heart valve annulus. The implantable device includes an arcuate body and an adjustment system (1004) configured to adjust the shape and/or size of the arcuate body. An adjustment tool (2006) can be coupled to the adjustment system so that the adjustment tool can be used to activate and control adjustment of the arcuate body. A sensor system is configured to be coupled to the implantable device. The sensor system includes a first sensor (3500a) configured to measure physiological data at an inflow portion of the valve annulus when the implantable device is implanted into the valve annulus, and a second sensor (3500b) configured to measure physiological data at an outflow portion of the valve annulus when the implantable device is implanted into the valve annulus.
