  • Patent number: 8652201
    Abstract: A method is provided for treating a cardiovascular disease, such as pulmonary arterial hypertension, an arrhythmia, or heart failure. One step of the method includes providing an apparatus. The apparatus includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion extending between the end portions. The proximal end portion includes a plurality of wing members extending from the main body portion. At least a portion of the expandable support member is treated with at least one therapeutic agent for eluting into a blood vessel. The expandable support member is inserted into the pulmonary vasculature and then advanced to a bifurcation in the pulmonary vasculature. The bifurcation includes the intersection of a first pulmonary vessel, a second pulmonary vessel, and a third pulmonary vessel. The expandable support member is secured at the bifurcation to treat pulmonary arterial hypertension, for example.

  • Publication number: 20140039613
    Abstract: A 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.

  • Publication number: 20110178597
    Abstract: An apparatus for replacing a diseased cardiac valve is movable from a radially collapsed configuration to a radially expanded configuration. The apparatus comprises an expandable support member and a prosthetic valve secured therein. The main body portion extends between first and second end portions and includes an outer circumferential surface, a circumferential axis extending about the circumferential surface, and a plurality of wing members spaced apart from one another by an expandable region. Each of the wing members includes first and second end portions and a flexible middle portion extending between the end portions. The second end portion is integrally formed with the main body portion. The first end portion is adjacent the circumferential axis and substantially flush with the outer circumferential surface in the radially collapsed configuration. The first end portion extends substantially radial to the outer circumferential surface in the radially expanded configuration.

  • Patent number: 7473237
    Abstract: An apparatus and method for automatically retroperfusing a coronary vein. The apparatus includes an intraluminal graft having a tubular body extending between a proximal end and a distal end. The proximal end is for fluidly connecting to an artery to automatically supply retrograde blood for retroperfusion. The tubular body and the distal end are extendable into a vein that is fluidly connected with the coronary vein to be retroperfused. The distal end includes an expandable stent for securing the distal end in the coronary vein.

  • Patent number: 7004925
    Abstract: 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.

  • Patent number: 6312464
    Abstract: A method of implanting a valve prosthesis in an atrio-ventricular valve of a patient's heart generally comprising securing a distal end of the valve prosthesis to the leaflets of the atrio-ventricular valve, and securing a proximal end of the valve prosthesis to the annulus of the atrio-ventricular valve, so that the chordae tendineae and the continuity between the papillary muscle and the valve annulus of the atrio-ventricular valve is preserved. Depending on the etiology of the valve disease, the method of the invention may comprises implanting the valve prosthesis in an intact atrio-ventricular valve, or alternatively, in a resected atrio-ventricular valve.
