  • Patent number: 8758432
    Abstract: A method for reducing regurgitation in a mitral valve using a blood flow controlling apparatus. The blood flow controlling apparatus comprises an anchoring means, preferably arranged to anchor the apparatus to a wall of the left ventricle. The blood flow controlling apparatus further comprises a valve means configured to expand in a direction transverse to blood flow. The valve means is preferably positioned within a native mitral valve and expands for making contact with the mitral valve leaflets during ventricular systole, thereby preventing blood from regurgitating back through the mitral valve into the left atrium. When blood flows from the left atrium to the left ventricle during ventricular diastole, the valve means collapses for allowing blood to pass freely through the mitral valve.

  • Publication number: 20140128967
    Abstract: Miniature axial flow pumps are implanted inside the heart or major arteries to provide hemodynamic support. These pumps commonly utilize tubular blood conduit tubes to transport blood across the aortic valve. The valve leaflets themselves are very thin and flexible, and will seal against the conduit if it is centered within the valve orifice. If the conduit is not centered, a leaflet can be pushed to the side of the aorta, preventing the leaflets from sealing and providing a path for backflow. If the blood flow conduit remains pushed against the side of the valve for a long period of time, thrombus may form in the crevice between the conduit and the aorta, causing serious thromboembolic events such as stroke, if the thrombus breaks free. The present invention provides a conduit support device that retains the conduit centered within the annulus of the natural heart valve.

  • Publication number: 20140081391
    Abstract: An embodiment of the invention includes a sewing cuff for aortic heart valves that better approximates native anatomy by better mating with the crown-like anatomical annulus. Limiting distortion of the crown-like annulus provides better blood flow and overall valve function and provides a physician greater ease of implantation since native anatomy is not flattened. Thus, the surgeon may attach sutures to the fibrous tissue of the crown-like anatomical annulus without distorting the shape of the native anatomy. An embodiment includes a scalloped sewing cuff assembly (with semilunar arches) that tracks the crown-like annulus. Another embodiment provides a sewing cuff positioned over the majority of the valve's length, thus allowing the surgeon greater flexibility as to where he or she can attach sutures to the surgical annulus. Conventional valves, which are primarily “low-profile” devices, do not offer such ability. Other embodiments are described herein.

  • Publication number: 20140074229
    Abstract: A device for the transvascular implantation and fixation of prosthetic heart valves having a self-expanding heart valve stent (10) with a prosthetic heart valve (11) at its proximal end is introducible into a patient's main artery. With the objective of optimizing such a device to the extent that the prosthetic heart valve (11) can be implanted into a patient in a minimally-invasive procedure, to ensure optimal positioning accuracy of the prosthesis (11) in the patient's ventricle, the device includes a self-expanding positioning stent (20) introducible into an aortic valve positioned within a patient. The positioning stent is configured separately from the heart valve stent (10) so that the two stents respectively interact in their expanded states such that the heart valve stent (10) is held by the positioning stent (20) in a position in the patient's aorta relative the heart valve predefinable by the positioning stent (20).

  • Patent number: 8657872
    Abstract: Methods and apparatus are provided for repairing or replacing a defective cardiac valve including an anchor having a double helix configured to engage the cardiac valve leaflets of a diseased or defective cardiac valve, and a replacement valve body disposed in an expandable stent configured to be disposed within the anchor so that the anchor limits expansion of the expandable stent. The expandable stent of the replacement valve body may be self-expanding or mechanically expanded, e.g., using a balloon catheter or catheter-based mandrel and the valve body may be formed of animal tissue or a synthetic fabric.

  • Publication number: 20140052242
    Abstract: A prosthetic heart valve for functionally replacing a previously implanted prosthetic heart valve is disclosed. The prosthetic heart valve includes a collapsible support structure with leaflets and anchors mounted to the support structure. The support structure also includes an inflow end and an outflow end. The anchors include a radially outwardly extending first anchor proximate to the inflow end and a radially outwardly extending second anchor proximate to the outflow end. The first anchor includes a first configuration and the second anchor includes a second configuration where the first configuration is different than the second configuration. The previously implanted prosthetic heart valve serves as a platform for securement of the prosthetic heart valve to the patient's native tissue.

  • 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.

  • Patent number: 8641757
    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.
