摘要： A minimally-invasive annuloplasty ring for implant at a mitral annulus. The annuloplasty ring has an inner core member with a C-shaped plan view that generally defines an oval with a major axis and a minor axis, and is symmetric about the minor axis. A posterior portion of the core member bisected by the minor axis has a thicker radial dimension than a pair of free end regions terminating on an anterior side of the core member. The radial thickness smoothly transitions between the posterior portion and the end regions. The inner core member may be covered with a fabric, and is a superelastic metal so that it can be straightened out and delivered through an access tube. The curvatures and thicknesses around the core member are selected so that the strain experienced when straightened does not exceed 7-8%.

摘要： Suture locking clamps for securing prostheses such as heart valves or annuloplasty rings with sutures and without knots improve the ease of implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.

摘要： Devices and methods for securing prostheses such as heart valves or annuloplasty rings with sutures and without using knots are disclosed. The devices are particularly well suited for traditional surgery or minimally invasive surgery, and improve the ease of implantation by eliminating surgical knots a clinician would normally tie in the limited space in and around the implant site. The devices have opposed the clamp halves surrounded by a coil spring. Sutures pass between the clamp halves and the coil spring has an inner coil diameter sufficient to compress the sutures between the clamp. A retention member positioned between the clamp halves maintains a minimum space and therebetween to enable the locking device to be slid along the sutures into position, and to adjust the tension of the sutures therethrough. A delivery tool may be used to deliver and deploy the locking devices.

摘要： A cardiac implant system including a cardiac implant such as an annuloplasty ring, a prosthetic heart valve, or a valved conduit pre-assembled at the time of manufacture with devices for securing the implant to a heart valve annulus using knotless suture fasteners. The knotless suture fasteners may be embedded within a pliant sealing edge of the cardiac implant, or they may be positioned adjacent to the sealing edge. The knotless suture fasteners are spring-biased so as to grip onto annulus anchoring sutures pass to therethrough upon removal of a restraining device, such as a hypotube inserted within the suture fasteners. Guide tubes are assembled in line with the suture fasteners to permit introduction of suture snares that pass through the suture fasteners and through the sealing edge to facilitate capture of the pre-installed annulus anchoring sutures.

摘要： Sensor-integrated prosthetic valves that can comprise a variety of features, including a plurality of valve leaflets, a frame assembly configured to support the plurality of valve leaflets and define a plurality of commissure supports terminating at an outflow end of the prosthetic valve, a sensor device associated with the frame assembly and configured to generate a sensor signal, for example, a sensor signal indicating deflection of one or more of the plurality of commissure supports, and a transmitter assembly configured to receive the sensor signal from the sensor device and wirelessly transmit a transmission signal that is based at least in part on the sensor signal.

摘要： Methods of deploying knotless suture locking clamps for securing prostheses such as heart valves or annuloplasty rings to facilitate implantation. The clamps have opposed clamp halves separated by a slot opening to one side and surrounded by a biasing member such as one or more C-clip springs. Sutures pass laterally into the slot which is held open by a retention member positioned between the clamp halves. The locking clamp slides along the sutures into position, the tension of the sutures is adjusted, and the retention member removed to allow the biasing member to clamp the sutures between the clamp halves. A delivery tool used to deliver and deploy the locking clamps contains a number of clamps within a delivery tube in a stack and bonded together for safety and a common retention member. The tool has a longitudinal channel on one side for entry of sutures.
