    摘要: An apparatus and method for replacing a cardiac valve includes an expandable support member having oppositely disposed first and second ends, a main body portion extending between the ends, and a prosthetic valve within the main body portion. The main body portion has an annular shape for expanding into position in the annulus of the valve. The first and second ends include a plurality of upper and lower wing members movable from a collapsed condition into an extended condition for respectively engaging a first section of cardiac tissue surrounding the valve and for engaging a portion of the native valve leaflets to pin the leaflets back against the annulus. The second end further includes at least two strut members spaced apart from each other. A respective one of the strut members is attached to at least one commissural section of the prosthetic valve to prevent prolapse of the valve leaflets.

    摘要: An apparatus for replacing a cardiac valve having at least two native valve leaflets includes an expandable support member with oppositely disposed first and second ends and a main body portion extending between the ends. The first and second ends respectively include a plurality of upper and lower wing members respectively having first and second magnetic components. The wing members extend from the main body portion and are spaced circumferentially thereabout. Secured within the main body portion is a prosthetic valve having at least two valve leaflets. The second end further includes at least two strut members spaced apart from each other and attached to at least one commissural section of the prosthetic valve. The magnetic components are magnetically attracted to one another so that, when the apparatus is placed in the valve annulus, the wing members are pulled toward one another to secure the prosthetic valve in the annulus.

    摘要: An apparatus for automatically retroperfusing a coronary vein includes an intraluminal cannula having a main body portion extending between a proximal end portion and a distal end portion. The proximal end portion is for connecting to an artery outside of the pericardium to automatically supply oxygenated blood from the artery for retroperfusion. The main body portion and the distal end portion are insertable through a vein that is fluidly connected with the coronary vein and into the coronary vein. An expandable stent is attached to the distal end portion for expanding radially into engagement with the interior wall of the coronary vein to secure the distal end portion at a desired location within the coronary vein. Occluding structure for at least partially occluding the coronary vein is provided at the distal end to decrease the back-flow of blood into the right atrium during retroperfusion. The cannula includes passages that allow a limited amount of blood to bypass the occluding structure.

    摘要: An apparatus for modifying the annulus of a cardiac valve to reduce regurgitation of blood flow through the cardiac valve includes a first annuloplasty ring having a first diameter and being disposed about a first aspect of the annulus of the cardiac valve. The apparatus also includes an elongate flexible body having proximal and distal end portions and being insertable into the first annuloplasty ring. The elongate flexible body has an adjustable mechanism for selectively adjusting the elongate flexible body from a first relaxed configuration to a second tensioned configuration. The first annuloplasty ring is adaptable to obtain a second smaller diameter and to cause the annulus of the cardiac valve to be modified and reduce regurgitation of blood flow through the cardiac valve when the elongate flexible body obtains the second tensioned configuration.

    摘要: A stentless bioprosthetic valve includes at least one piece of biocompatible material comprising a bi-leaflet conduit. The conduit has a distal end, a proximal end defining a first annulus for suturing to the valve annulus of a heart, and leaflets extending between the proximal and distal ends. The distal end defines a second annulus having a profile substantially similar to a first annulus profile, at which the leaflets terminate. The second annulus is sutured to free edges of the leaflets of the native mitral valve that remain intact following resection of the native mitral valve. Therefore, the native chordae tendineae continue to provide prolapse prevention and left ventricular muscle support functions in addition to maintaining continuity between the valve annulus and the papillary muscles. The second annulus is spaced from the papillary muscles. A method for replacing the native mitral valve with a stentless bioprosthetic valve is also provided.

    摘要: An apparatus for remodeling the annulus of a cardiac valve includes a first elongate flexible member having a distal end portion and a proximal end portion interconnected by a main body portion. The distal end portion is steerable from the proximal end portion and advanceable to one side of the cardiac valve annulus via a percutaneous approach. The distal end portion includes a terminal end and a connecting section spaced apart by a predetermined length. The connecting section has a structure for disconnecting from the main body portion, in addition to a structure for interconnecting with the terminal end to form a ring of a predetermined shape adjacent the one side of the cardiac valve annulus. The distal end portion further includes a mechanism for attaching to the cardiac valve annulus so that, when the ring is formed, the distal end portion contracts and thereby remodels the annulus of the cardiac valve. The apparatus can also include a second elongate flexible member for positioning on the opposite side of the native valve annulus and which may be magnetically attracted to the first flexible member in order to attach the apparatus to the valve annulus.

    摘要: A method and apparatus for replacing both the native mitral valve and the native aortic valve in a heart with a stentless bioprosthetic graft is provided. The bioprosthetic graft comprises a harvested homograft that includes a mitral valve portion and an aortic valve portion, and an extension portion made of a biocompatible material. The extension portion is sutured to the homograft and is for suturing to the left atrial wall of the heart to close an incision in the left atrial wall following implantation of the mitral valve portion and the aortic valve portion of the homograft.
