  • Publication number: 20060025854
    Abstract: A cardiovascular prosthetic valve includes a cuff having a distal end and a proximal end. An inflatable structure is coupled to the cuff and has at least one inflatable channel that forms a toroidal structure. A valve is coupled to the cuff; the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction. In one arrangement, the distal end of the cuff has a non-circular cross-section with respect to the flow and the non-circular cross-section is configured to affect the performance of an adjacent valve. In another arrangement, the cuff includes an anchor moveable from a first position to a second position. In another arrangement, control wires are coupled to the cuff.

  • Publication number: 20060020332
    Abstract: A method of treating a patient utilizes a temporary valve. In one embodiment, an inflatable structure of a temporary valve is inflated at a cardiovascular site in fluid communication with a native valve. At least a portion of the native valve is removed translumenally. A prosthetic valve is deployed to compliment or replace a native valve. The temporary valve is removed.

  • Publication number: 20060020333
    Abstract: A method of implanting a prosthetic valve within the heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A first chamber of the inflatable structure is inflated and then, independently, a second chamber of the inflatable structure is inflated.

  • Publication number: 20060020327
    Abstract: An implantable prosthetic valve having an in situ formable support structure and methods of deploying such a valve are disclosed. In one arrangement, the valve has a base and at least one flow occluder. A first flexible component which is incapable of retaining the valve at a functional site in the arterial vasculature extends proximally of the base of the valve. A second flexible component which is incapable of retaining the valve at a functional site in the arterial vasculature extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.

  • Publication number: 20060020334
    Abstract: A method of implanting a prosthetic valve within a heart comprises translumenally advancing a prosthetic valve comprising an inflatable structure to a position proximate a native valve of the heart. A portion of the inflatable structure that is distal to the native valve is inflated. A portion of the inflatable structure that is proximal to the native annular valve is inflated.

  • Publication number: 20050273160
    Abstract: The present invention involves placing a valve between the left atrium and the lung to prevent regurgitant flow from increasing the pulmonary pressures, which may lead to pulmonary edema and congestion. Mitral stenosis or poor synchronization of the mitral valve may add additional pressures to the left atrium thus raising the pulmonary pressures and leading to congestion in the lung vasculature. By blocking the additional pressures from the mitral regurgitant flow from reaching the pulmonary circulation, the left atrium may act as a sealed vessel to allow additional aortic output. The valve placement can be intralumenal or attached to the ostium of the atrium. The device can be placed via the vascular conduits or through a surgical procedure into the pulmonary circulation. One or more devices may be placed in each of the four pulmonary veins. Additionally only one, two, three or all four veins may be implanted with the valve as desired by the physician.

  • Publication number: 20050222678
    Abstract: Disclosed are methods and devices for applying pressure to an adjacent tissue structure, such as the annulus of the mitral valve. An adjustable implant is provided with an elongate control line having a distal end connected to the implant and a proximal end spaced apart from the implant. The device enables post implantation adjustment, by accessing the proximal end of the control line and manipulating the control line to adjust the implant.

  • Publication number: 20050060030
    Abstract: Disclosed are implants and methods for remote remodeling of a mitral valve annulus. The implant comprises a body transformable from a flexible configuration for navigation to a treatment site, to a remodeling configuration for, in one application, applying pressure to the posterior leaflet of the mitral valve. On board electronics allow post deployment adjustment of the implant.

  • Publication number: 20040153146
    Abstract: A medical apparatus and method for remodeling a mitral valve annulus adjacent to the coronary sinus includes an elongate body having a proximal end and a distal end. The elongate body is movable from a first, flexible configuration for transluminal delivery to at least a portion of the coronary sinus to a second configuration for remodeling the mitral valve annulus.
