An implant, system, and method of deployment includes a plurality of anchor housings coupled to one of the proximal end or distal end of an implant frame. Each anchor housing may include an anchor sleeve disposed within a bore of the anchor housing, the anchor sleeve having a lumen extending therethrough including features disposed on an internal wall of the lumen for translatably supporting at least one anchor. Each anchor sleeve may be independently translatable within the bore of the anchor housing to control a distal extent of travel of the at least one anchor through the at least one anchor housing.

The present disclosure provides a method for contracting heart tissue using a transcatheter annuloplasty system. The system includes a plurality of anchoring components, a flexible tightening string and a flexible delivery member. The tightening string is coupled with a first anchoring component and the delivery member. The method includes: implanting the first anchoring component into the heart tissue, the tightening string entering a body along with the first anchoring component, and a proximal end of the delivery member extending outside the body; delivering each of remaining anchoring components, along the delivery member, to the tightening string and implanting it into the heart tissue; and tightening the tightening string. Therefore, after the plurality of anchoring components are implanted at different positions, along a circumferential direction of the mitral annulus, the tightening string is tightened to adjust a spacing of the anchoring components so as to contract the heart tissue.

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.

A prosthetic mitral valve includes an anchor assembly, a strut frame, and a plurality of replacement leaflets secured to the annular strut frame. The anchor assembly includes a ventricular anchor, an atrial anchor, and a central portion therebetween. The ventricular anchor and the atrial anchor are configured to flare radially outwards relative to the central portion. The annular strut frame is disposed radially within the anchor assembly and is attached to the anchor assembly. The central portion is configured to align with a native valve orifice and the ventricular anchor and the atrial anchor are configured to compress native cardiac tissue therebetween.

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%.

Annuloplasty device for use on a posterior annulus of a mitral valve, which is deployable to the mitral valve by means of a vascular delivery device, such as a catheter, and positionable along the curvature of the annulus, including at least a first and a second branch, each configured to extend along at least a section of the annulus, with a first end and a second end, at least one guiding means for guiding the first and the second branches relative to one another, at least one fixing means for fixing the device to the annulus, and at least one anchor means arranged on each of the first and second branches, whereby the first and the second branches are movable relatively to one another, so that the anchor means engage with the annulus thereby pulling the annulus together when the first and second branches are moved in opposite directions.

Various embodiments of an implant delivery systems including at least one removable actuator to reshape a valve annulus are described. The systems may use the removable actuator to customize annular reshaping at a treatment site and withdraw the actuator from the treatment site following custom reshaping to provide a low profile annuloplasty implant.

An annuloplasty band and method of implantation. The band is shaped and sized to avoid the adjacent aortic valve structure and better protects against dehiscence along the muscular mitral annulus. The band is asymmetric and when implanted spans more around the side of the mitral annulus having the posterior commissure than the side with the anterior commissure. The band has a saddle shape with a posterior upward bow centered on a minor axis of the mitral annulus, and a span extending clockwise therefrom is longer than a span extending counter-clockwise. The longer span may be 150° while the shorter span extends 90°. A set of rings may have different saddle profiles and different plan view shapes for different sized bands. A method includes implanting so that the band extends over the posterior leaflet and a short distance past the posterior commissure outside of the anterior leaflet.

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.

An implant comprises a wall that surrounds a lumen. A delivery tool comprises a catheter, a control assembly, and an ultrasound tool. The catheter is transluminally advanceable into a subject, and has a distal opening. The implant can be delivered via the catheter. The control assembly can advance at least a portion of the wall out of the distal opening, and can steer the catheter to place the portion against a site of a tissue of the subject, the site disposed distally from the portion and opposite the distal opening. The ultrasound tool can (i) position an ultrasound transceiver within the lumen and facing the portion, and (ii) facilitate imaging of the site by transmitting ultrasound energy through the portion. An anchor driver can anchor the implant to the tissue by driving an anchor through the portion and into the site. Other embodiments are also described.
