  • Publication number: 20210220122
    Abstract: A prosthesis is provided for implantation at a native semilunar valve of a native valve complex, the native valve complex having three semilunar sinuses and three native commissures. The prosthesis includes a valve prosthesis support, which comprises a support structure comprising exactly three engagement arms that meet one another at three respective junctures. The engagement arms are shaped so as define three peak complexes at the three respective junctures, and three trough complexes, each of which is between two of the peak complexes. Upon implantation of the prosthesis, each of the engagement arms is at least partially disposed within a respective one of the semilunar sinuses, such that each of the peak complexes is disposed distal to and in rotational alignment with a respective one of the native commissures, and each of the trough complexes is disposed at least partially within the respective one of the semilunar sinuses.

  • Publication number: 20200297361
    Abstract: A device for fracturing calcifications in heart valves includes a tube formed with at least two longitudinal slits that form at least two struts. Each of the struts includes two or more pairs of notches formed on opposite sides of the strut. The struts have a contracted orientation in which the struts are not expanded outwards from the tube and an outwardly expanded orientation in which the struts are expanded outwards from the tube and have sufficient strength and rigidity to impact and fracture a calcification in a heart valve.

  • Patent number: 10195033
    Abstract: A prosthetic apparatus for implantation at a native valve complex includes a main body configured for placement within the native valve, at least one downstream arm and at least one upstream arm, each coupled to and disposed outside of the main body. The main body includes a compressed state for delivery and an expanded state. In the expanded state, a space exists between the downstream arm and an outer surface of the main body to receive an edge of a native valve leaflet. A portion of the downstream arm is configured to extend behind the received native leaflet and engage a downstream surface of the native valve complex while the edge of the received native leaflet is not engaged by the downstream arm. The upstream arm is configured to engage an upstream surface of the native valve complex at a location opposite the portion of the downstream arm.

  • Patent number: 10188516
    Abstract: A loading tool for withdrawing, crimping, and loading a stent-mounted valve into a delivery catheter, and for pushing the stent-mounted valve from the delivery catheter into a native heart valve orifice. The loading tool comprises at least one connector adapted for being removably connected to the stent of the stent-mounted valve. A crimping tool having a generally converging shape is adapted for use with the loading tool. Following connection of the loading tool to the stent-mounted valve, the loading tool operates to allow the stent-mounted valve to be drawn through the crimping tool, and loaded, in, a crimped state, into a delivery catheter. Also disclosed is a kit of the of the various components for effecting the delivery of the stent-mounted valve and a method for withdrawing, crimping, and loading a stent-mounted valve from a storage container into a delivery catheter for the performance of a transcatheter valve implantation procedure.

  • Patent number: 10004601
    Abstract: A prosthetic apparatus includes a main body having a lumen and configured for placement within a native annulus of a native valve complex. The main body is radially compressible to a radially compressed state for delivery into the heart and self-expandable from the compressed state to a radially expanded state. The apparatus also includes at least one arm coupled to and disposed outside of the main body. The arm being coupled to the main body such that when the main body is compressed to the compressed state, a leaflet-receiving space between the arm and an outer surface of the main body increases to receive a native valve leaflet therebetween, and when the main body expands to the expanded state in the absence of any radial inward forces on the main body or the arm, the space decreases to capture the leaflet between the outer surface of the main body and the arm.

  • Patent number: 9918825
    Abstract: An endovascular stent-graft is provided that includes a structural member, which includes structural stent elements, at least a portion of which define a stent body when the stent-graft assumes a radially-expanded state; and a fluid flow guide. When the stent-graft assumes the radially-expanded state, (a) a first subset of the structural stent elements are configured to cause the stent body and the fluid flow guide to define a bulge that extends radially outward and has a greatest cross-sectional area that is equal to at least 120% of a cross-sectional area of a narrowest portion of the stent-graft rostral to the bulge, and (b) a second subset of the structural stent elements are not configured to cause the fluid flow guide to define the bulge. The structural stent elements of the first subset at least partially overlap the structural stent elements of the second subset lengthwise along the stent body.
