Abstract: A method for replacing a native heart valve includes advancing a delivery catheter having a valve prosthesis disposed along a distal end portion thereof, wherein the valve includes an inner frame having an hourglass shape and an outer sealing frame connected to and surrounding the inner frame. A valve body is mounted within the inner frame and includes a plurality of leaflets. The leaflets have longitudinal curvatures when in an open position, wherein the curvatures are shaped for conforming to the curved interior surface of the inner frame. This combination of features reduces the possibility of blood stagnating between the leaflets and inner frame, which reduces the possibility of thrombus formation.

Abstract: Disclosed herein are embodiments of an expandable replacement heart valve prosthesis. The expandable replacement heart valve prosthesis can include a number of different features, such as an hourglass (or generally hourglass) shape in the fully expanded position, anchor stiffening features, and improved retraction/retention configurations. For example, certain struts on the prosthesis can have different thicknesses/widths than other struts to improve compressibility.

CPC classification number: A61F2/2436 , A61F2/2439
Abstract: A delivery system includes a suture attachment mechanism for maintaining a connection to a heart valve after initial deployment, thereby allowing recapture of the heart valve if desired. A plurality of suture portions is provided along a distal end portion of the delivery system, each suture portion having a first end fixed to the delivery system and a second end releasably coupled to a retention member on the delivery system. A knob on a handle of the delivery system is actuated for causing the second end of each suture portion to be released from its respective retention member, thereby allowing the suture portions to be decoupled from the heart valve. The suture portions are located only along a distal end portion of the delivery system for improving reliability and consistency.

Abstract: Devices, systems and methods are described herein to provide improved steerability for delivering a prosthesis to a body location, for example, for delivering a replacement valve to a native valve location in a heart. Disclosed are a number of features that can improve steerability or release of the prosthesis into the body location. In one preferred delivery system, a proximal handle can be manipulated to apply tension to a pair of diametrically opposed axial runner wires extending through lumens in a wall of a flexible tubular shaft. By applying tension to a pair of axial runner wires, the tubular shaft can be stiffened along a plane extending substantially through the pair of axial runner wires, while the shaft is permitted to freely bend in a perpendicular plane. This feature advantageously provides the ability to adjust the steerability and flexibility of a tubular shaft to meet the requirements of a particular procedure.
