  • Publication number: 20210022865
    Abstract: A method for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.

  • Patent number: 10813759
    Abstract: A dual member stent-valve for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.

  • Patent number: 10595842
    Abstract: An access catheter provides access for a large bore stiff therapeutic catheter across the atrial septum from above via the superior vena cava. The access catheter has an expandable member that direct a delivery tube outwards in a radial direction to place a delivery tube opening into direct contact with the fossa ovalis. The braided expandable member allows blood flow to pass when it is expanded; the expandable member provides support against the opposite wall of the right atrium. A hollow dilator tube enters the delivery tube to form a tenting shape to the fossa and a guidewire is passed across the fossa ovalis. Standard procedure allows delivery of the therapeutic catheter over the guidewire.

  • Publication number: 20190388222
    Abstract: A transcatheter stent-valve having replacement leaflets that are attached along their free edges. The stent-valve frame has supports that extend distally of the replacement leaflets to two fastening sites. The replacement leaflets are attached along a leaflet base forming a linear attachment to the stent-valve frame. The free edges of the leaflets have cords attached; the cords attach the free edges of the leaflets to the fastening sites located on the supports. The stent-valve can be a single component stent-valve or it can be a second component of a dual component stent-valve.

  • Publication number: 20190269412
    Abstract: An occlusion device intended for blocking perivalvular leak channels that are found following heart valve implantation between the heart valve and the surrounding tissue. The occlusion device has a stent and a covering that is attached to the stent surface. A blocking fabric extends across the lumen of the stent to block blood flow. The stent pattern and wall structure provide for small radius of curvature bends to fill narrow channels that cause the perivalvular leaks.

  • Publication number: 20190209320
    Abstract: An annuloplasty device formed from a Nitinol stent frame that expands into contact with the annulus above the native leaflets. A torus balloon activates barbs along the perimeter to fasten the stent frame to the annulus. A cinch ring is placed under tension to reduce the perimeter of the stent frame. The cinch ring and torus balloon are implanted along with the stent frame.

  • Publication number: 20190142582
    Abstract: A two component system for replacing mitral valves using a transcatheter approach. The first component uses a torus balloon to activate barbs into the mitral annulus after the first component stent frame has been delivered. A closed ring in the first component provides a landing site for delivery of a second component that contains replacement leaflets. The second component straddles the mitral annulus such that impingement upon the left ventricular outflow track does not occur. The second component frame contains open regions that help to prevent blood stagnation.

  • Patent number: 10238395
    Abstract: A compression stent for applying a localized high stress against a blood vessel wall to cause vessel wall compression and blockage of sympathetic and nerve signal transmission within the wall of a blood vessel. The compression stent can also sever nerves located in the vessel wall. Blockage of sympathetic nerve signal transmission reduces hypertension and improves other clinical problems that are associated with sympathetic nerve signals.

  • Publication number: 20190021781
    Abstract: A device for compressing a renal artery prior to delivery of radiofrequency ablative energy to the renal nerves. The device includes a stent structure with a focal region that expands outwards to place the RF electrodes located on the stent structure in close proximity to the renal nerves. A covering is applied to the stent structure to prevent intimal hyperplasia.
