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: Embodiments of a crimping device for crimping a radially expandable and compressible prosthetic valve are disclosed. A crimping device can comprise a housing configured to receive a prosthetic valve in a radially expanded state. The housing member can include a funnel segment and an outlet in communication with the funnel segment. The crimping device can further comprise an actuator rotatably coupled to the housing, wherein rotation of the actuator relative to the housing causes the prosthetic valve to move axially through the funnel segment such that at least a portion of the prosthetic valve compresses radially by engagement with the funnel segment and exits the crimping device via the outlet.

Abstract: A mitral valve prosthesis includes an hourglass shaped inner frame and a bulbous outer frame. A valve body having a plurality of leaflets is positioned within an interior region of the inner frame. The leaflets are shaped to substantially conform to an interior surface of the inner frame when the leaflets are in an open position. As a result, the gap between the leaflets and the inner frame is decreased, thereby reducing the likelihood of thrombus formation. Ventricular anchors are preferably provided along a distal end of the inner frame. The anchors extend proximally for placement behind native mitral valve leaflets. A fabric skirt may extend along an inner or outer surface of the outer frame. In preferred embodiments, the fabric skirt extends distally beyond a distal end of the outer frame and is adapted for forming a seal along the mitral valve annulus.

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 mitral valve to a native mitral valve location. The steerable delivery system can contain a steerable rail configured for multi-plane bending to direct a distal end of the delivery system.

Abstract: Disclosed herein are embodiments of stabilizers for use in delivering a replacement heart valve. The stabilizers can receive a portion of a delivery system, such as a handle, to prevent unwanted motion of the delivery system. The stabilizer can include a linear actuator for adjusting a position of the delivery system once held within the stabilizer.

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 adapters that can be used to translate and/or rotate the position of a delivery system, such as for use with a replacement mitral valve. The adapters can allow for three-dimensional motion of the delivery system, thus allow for precise positioning and movement of the delivery system during use by an operator.

Abstract: Apparatuses, systems, and methods for prosthetic valves. An implantation site may comprise a native heart valve or another implantation site in examples. Examples may be utilized for improved anchoring and sealing of flow (e.g., paravalvular leakage) with a native heart valve having calcification. Examples may reduce the possibility of obstruction of a left ventricular outflow tract (LVOT) of a heart, whether resulting from implantation of a prosthetic valve or otherwise.
