Systems, devices and methods for resizing a valve annulus are described. An implant is delivered proximate a mitral valve, the implant comprising a tubular body and a plurality of piercing helical anchors, the tubular body comprising an proximal diameter and a distal diameter. Tissue proximate the mitral valve is engaged by rotating the plurality of anchors with corresponding rotational drivers. The tubular body may be transitioned from a first structural configuration having the proximal diameter smaller than the distal diameter to a second structural configuration having the proximal diameter larger than the distal diameter.

A cardiac valve prosthesis including an armature for anchorage of the valve prosthesis at an implantation site. The armature defining a lumen for the passage of the blood flow and having a longitudinal axis, and a set of prosthetic valve leaflets supported by said armature and configured to move, under the action of blood flow, in a radially divaricated condition to enable the flow of blood through said lumen in a first direction, and in a radially contracted condition, in which said valve leaflets co-operate with one another and block the flow of blood through the prosthesis in the direction opposite said first direction. The armature including an annular part and a pattern of arches struts carried by said annular part, said pattern of arched struts having proximal ends connected to said annular part, and distal ends spaced axially from the proximal ends and opposite said annular part, a plurality of sets of anchoring formations configured to protrude radially outwardly of said annular part, each set being supported by a least one of said annular part and a corresponding arched strut, and a plurality of support posts, each support post being supported by adjacent arched struts, wherein the sets of anchoring formations alternate with the support posts around said longitudinal axis.

A two-part aortic annular support system for supporting an aortic annulus during aortic valve repair procedures for prevention of further annular dilation. The first part comprises a composite annular ring that is positionable from within an aortic valve into the left ventricular outflow tract at the level of annular plane. The composite ring comprises a semi-rigid section and a resiliently deformable section. The semi-rigid section is shorter in length than the deformable section. The deformable section is extendible into a commissure of the aortic valve. The second part is a resilient band that is positionable external to the aortic root. The resilient band is securable to the composite ring through the aortic annulus by suturing. The present disclosure also relates to a use of the aortic annular support system and a method of inserting and securing the aortic annular support system during a surgical intervention.

Systems, devices, and methods for adjusting cardiac tissue are described involving adjustment of a frame element of an implantable device relative to the cardiac tissue. At least a component of the implantable device is rotated relative to the cardiac tissue and/or another component of the implantable device. At least a component of the implantable device is axially movable relative to the cardiac tissue and/or another component of the implantable device.

An exemplary valve repair device for repairing a native valve of a patient includes a coaption element, a pair of paddles, and barb portions. The barb portions extend directly from at least one of the coaption element and the pair of paddles.

Disclosed is a composite skirt for a prosthetic heart valve. A stent includes an inflow segment, a transition segment and an outflow segment; the composite skirt includes at least two of: (1) a first skirt disposed at the inflow segment, (2) a second skirt disposed at the transition segment, and (3) a third skirt disposed at the outflow segment, wherein for the composite skirt, different skirt parameters are configured according different arrangement regions to adapt to primary tissues and reduce regurgitation. A prosthetic heart valve is further disclosed. For the composite skirt of this invention, in view of different functions in different regions of the valve, the skirt parameters of different regions are set such that the skirt is matched with a structure of the stent, thereby improving the functions of the prosthetic heart valve.

A knotless suture fastener installation system for securing medical devices such as cardiac implants. The knotless suture fasteners may be spring-biased so as to grip onto sutures passed therethrough. The system includes a fastener deployment tool with a proximal handle and a distal shaft to which a fastener cartridge attaches. A plurality of disposable cartridges are sequentially attached to the end of the deployment tool and used to secure the medical implant one fastener at a time. The deployment tool may also cut the sutures being fastened.

A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

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 transcatheter valve implant assembly has a ventricular assist device, a prosthetic valve, a stent frame structure, and a docking station, and is implanted at an aortic or a pulmonary valve. During implantation, the native valve leaflets of the respective valve at the implantation site are engaged with the prosthetic valve and/or the stent frame structure while the stent frame structure is connected to the docking station with the prosthetic valve adjacent to the proximal end of the stent frame structure. The ventricular assist device is inserted into the interior the stent frame structure with an inlet of ventricular assist device positioned in the respective ventricle associated with the implantation site and the outlet of the ventricular assist device positioned to discharge into the respective blood vessel associated with the implantation site. The ventricular assist device is releasably connected with the stent frame structure and the docking station.
