  • Patent number: 10722362
    Abstract: An implantable heart valve device has a main body including a first end portion and a second end portion. The main body is configured to be implanted around a native leaflet of a heart valve such that the first end portion is on an atrial side of the leaflet and the second end portion is on a ventricular side of the leaflet, and such that the main body can coapt with an opposing native leaflet during operation of the heart valve. One of the first or second end portions comprises a coupling assembly, and the other of the first or second end portions comprises a coupling member configured to extend through the native leaflet when the heart valve device is implanted in a heart valve. The coupling assembly is configured to releasably engage the coupling member to permit adjustment of the relative positions of the first and second end portions.

  • Patent number: 10716690
    Abstract: A system for deploying a prosthesis over a Carina between an ipsilateral lumen and a contralateral lumen includes a guidewire, a guidewire capture catheter, a self-expanding tubular prosthesis, and a delivery catheter. The guidewire is first placed in the ipsilateral lumen. The guidewire capture catheter is then advanced from the contralateral lumen to a position at or above the ipsilateral lumen. The guidewire is typically advanced through an occlusion, which may be a total occlusion, and captured by a capture element on the guidewire capture catheter. The guidewire capture catheter pulls the guidewire out through the contralateral side, and the guidewire is used to advance a delivery catheter from the ipsilateral side. The delivery catheter delivers a first segment of the tubular prosthesis in the ipsilateral lumen and a second segment of the prosthesis in the contralateral lumen.
