  • Patent number: 10022222
    Abstract: The present embodiments relate to systems and methods for treating lumenal valves. Particularly, and in accordance with one aspect, the present disclosure is directed to methods and systems for partial or complete replacement of lumenal valves. An exemplary catheter in accordance with the disclosure includes an elongate body having a proximal end and a distal end, and a retractable sheath mounted on the elongate body proximate the distal end. The sheath and elongate body cooperating to define a first annularly-shaped compartment between the body and sheath. The catheter further includes a valve prosthesis mounted in the compartment, the prosthesis having proximal and distal ends connected to a means for deploying the valve prosthesis from the catheter.

  • Publication number: 20170340329
    Abstract: The present teachings provide methods for resizing, reducing, and closing left atrial appendage. Specifically, a percutaneous trans-septal access is first established from outside the body to a patient's LAA. At least two tissue anchors are then implanted inside the LAA chamber and along the tissue wall. At least one anchor is implanted near the opening of the LAA camber. Both tissue anchors are pulled together so that the wall of the LAA chamber collapse. The LAA chamber is therefore resized, reduced, and/or closed off completely. This closure method and system could be used alone in closing LAA chamber. This closure method and system could also be used in addition to other treatment mechanisms, such as filling the LAA chamber with space-filling material, then closing off its opening.

  • Publication number: 20140358223
    Abstract: The disclosure provides valve prostheses and methods of installation. One embodiment of the prosthesis has a generally tubular body adapted for placement proximate a mitral annulus. The tubular body has a generally tubular upper portion adapted to substantially reside in the left atrium above the mitral annulus. The generally tubular upper portion has a first circumferential wall that is outwardly biased to urge against cardiac tissue of the left atrium. The tubular body also includes a lower portion extending downwardly from the generally tubular upper portion, the lower portion being configured to substantially reside in the left ventricle below the mitral annulus. The lower portion of this embodiment can be defined by an generally circumferential wall that extends downwardly from the generally tubular upper portion. The generally circumferential wall has a first circumferential end and a second circumferential end, and defines a circumferential extent therebetween.

  • Publication number: 20130172990
    Abstract: A system and method for the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular or adjacent tissue each fixed by a retainer is described. The system includes four devices to achieve such percutaneous direct plication annuloplasty. The first is a crossing catheter having a prolapseable or curved tip. Second, a deflecting guide catheter is used to provide a means for guiding the plication device into proper position at the subvalvular region of the mitral valve annulus. Third, the plication device is then used to make plications in the subvalvular region of the mitral valve annulus. Fourth, a “C” shaped retainer with deformable ends is deployed by the plication device in order to retain the plicated tissue in the plicated form.
