摘要： An implant, disposed within a catheter, comprises a ring, anchors, and adjustment elements. The ring comprises struts arranged in a pattern of alternating peaks and troughs. Each strut has a first end-portion and a second end-portion. Each peak is defined by convergence of adjacent first end-portions disposed at an angle with respect to each other, and each trough is defined by convergence of adjacent second end-portions. Each of the anchors has a longitudinal axis, is coupled to the ring at a respective trough, and is configured to be driven along the longitudinal axis with respect to the trough and into tissue of the heart. Each of the adjustment elements is configured to adjust an angular disposition between a respective pair of the struts. A first adjustment element is coupled to its pair, and a second adjustment element is coupled to its pair distal to the first adjustment element.

摘要： Devices, systems, and methods for coupling a prosthetic implant to a fenestrated body are disclosed herein. In some embodiments, a branch stent graft is provided. The branch stent graft can include an engagement portion for engagement with an opening in a fenestrated body, such as a vessel wall or an aortic stent graft. The engagement portion of the branch stent graft can be coupled to the fenestrated body such that the branch stent graft can move, rotate or shift relative to the fenestrated body but such that axial movement of the branch stent graft is restricted and/or prevented.

摘要： Disclosed are embodiments of replacement heart valves. Embodiments may include a collapsible and expandable frame comprising rows of cells. The frame may include a plurality of axial connection portions extending between top ends and bottom ends of the cells, wherein each axial connecting portion is shaped to bend for accommodating temporary changes in cell height during non-uniform compression of the replacement heart valve. Frames having these features are advantageous when advancing a replacement heart valve through a funnel-shaped compression tool. The axial connection portions are sufficiently flexible to accommodate changes in frame shapes during compression while also being sufficiently resilient for enhancing the structural integrity of the frame in the fully deployed state. The replacement heart valves are preferably dual-frame heart valves, wherein the axial connection portions form a portion of an inner frame and wherein an outer frame is provided for engaging tissue and forming a seal.

摘要： An epicardial device for reducing or preventing regurgitation of blood through a valve of a heart includes a main body having a segment adapted to apply force to an epicardial surface of the heart. A member that applies counterforce to the force applied by the segment is also provided. A foundation is configured to be anchored to the epicardial surface of the heart. The foundation includes a surface configured with attachment features. The device further includes a surface configured with mating attachment features configured to attach to the attachment features of the foundation. The mating attachment features and attachment features are separable and reattachable to allow repositioning of at least a portion of the device relative to the foundation.
