Abstract: A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.

Abstract: A delivery cylinder includes a first tubular portion and a second tubular portion having a plurality of struts coupled to the first tubular portion and defining a volume for containing a radially compressed prosthetic implant. The struts include proximal end portions and main body portions extending from the proximal end portions in both an expanded configuration and a contracted configuration. The proximal end portions of each strut include a pair of first recessed portions defined in longitudinal edges of the strut, and a pair of second recessed portions defined in the longitudinal edges distally of the pair of first recessed portions. The pair of first recessed portions reduces a width of the strut to induce bending of the strut at the pair of first recessed portions, and the pair of second recessed portions reduces the width of the strut to induce bending at the pair of second recessed portions.

Abstract: Disclosed herein are designs for improved inflatable structures for use during minimally invasive cardiovascular procedures. These inflatable structures facilitate the perfusion of blood through an anatomical structure, such as a heart valve, during the cardiovascular procedure. The inflatable structures are formed of a plurality of balloons arranged radially around a central location. The plurality of balloons form a lumen through which blood flows. Each balloon of the plurality is shaped or configured to stabilize the adjacent balloons, limiting their movement relative to each other. For example, some embodiments can feature balloons with a keystone shape that limits movement of the balloons inward toward the lumen. Some implementations can also include a support coil running through the lumen. The support coil holds enables the lumen to be open to perfusion even in the early stages of balloon inflation.

Abstract: An exemplary recapturable valve repair system for repairing a native valve of a patient during a non-open heart procedure has a delivery device, a valve repair device, and a tethering line. The delivery device has a catheter and a coupler. The valve repair device is configured to be delivered through the catheter and attach to a native valve of a patient. The valve repair device includes a coaption element, a proximal collar, and first and second paddles. The first and second paddles are connected to the coaption element. The coupler is releasably connected to the proximal collar. The tethering line connects the valve repair device to the delivery device for recapturing the valve repair device.

Abstract: An implantable prosthetic valve includes a radially collapsible and radially expandable annular frame. The frame includes an annular main body sized to be implanted within a native mitral valve annulus. The frame also includes an atrial sealing member coupled to and extending radially away from the main body. The atrial sealing member is sized to extend over tissue of the native mitral annulus within a left atrium to reduce paravalvular leakage. The atrial sealing member includes an inner zig-zag portion and an outer zig-zag portion. The inner zig-zag portion and the outer zig-zag portion are connected to the main body portion only via a fabric to enhance flexibility of the atrial sealing member relative to the main body. The prosthetic valve also includes a valve member disposed within an interior of the frame.

Abstract: A method of implanting a prosthetic apparatus preferably includes delivering the prosthetic apparatus to a native mitral valve and exposing ventricular anchors and a spacer body of the prosthetic apparatus from a distal end portion of a delivery apparatus. The ventricular anchors are controllably and forcibly expanded outwardly from the spacer body to an expanded configuration. The prosthetic apparatus is positioned relative to the native mitral valve such that native mitral valve leaflets are located between the ventricular anchors and the spacer body. The ventricular anchors are then contracted radially inwardly toward the spacer body to a compressed configuration. In the compressed configuration, the native mitral valve leaflets are secured between the ventricular anchors and the spacer body. After implantation, the spacer body is held between the native mitral valve leaflets, thereby blocking regurgitation and improving the function of the native mitral valve.

Abstract: A prosthetic heart valve includes a collapsible and expandable frame having a main body, an atrial portion, and at least one ventricular anchor. The atrial portion extends radially outwardly relative to the main body and the ventricular anchor extends from a ventricular end of the main body. The main body and the atrial portion are preferably separate metal components that are coupled together via sutures or a fabric member. The prosthetic heart valve also includes a valve structure that is supported in the main body of the frame. The valve structure has a plurality of leaflets for regulating the flow of blood in one direction.

Abstract: A method of implanting a prosthetic heart valve includes advancing a distal end portion of a catheter shaft through a patient's vasculature. The distal end portion of the catheter shaft includes an expansion device. A prosthetic heart valve is mounted on the expansion device with the expansion device and the prosthetic heart valve in a compressed configuration. The method further includes positioning the distal end portion of the catheter shaft and the prosthetic heart valve to an implantation location, and expanding the prosthetic heart valve and the expansion device from the compressed configuration to an expanded configuration. The expansion device includes an inner expandable member and a plurality of outer expandable members. The outer expandable members are distributed such that there are gaps providing perfusion passageways between the expansion device and the prosthetic heart valve when the expansion device is in the expanded configuration.
