    Abstract: An elongate distal protection device includes an intraluminal filter-occluder combination positioned at a distal end thereof. An expandable occluder is disposed within an expandable filter such that the filter and occluder are independently deployable. During use, the expanded occluder may be used first to stop embolic particles for aspiration thereof. Then, the occluder may be collapsed, leaving the filter expanded to capture any remaining embolic particles.

    Abstract: A medical device, method and system of treating the lumenal system of a patient are provided. The medical device includes a tissue plicator adapted and configured to form a plication of tissue proximate a target region of a patient. The medical device further includes a retainer applicator operatively associated with the tissue plicator. The retainer applicator is adapted and configured to apply a retainer to the plication to maintain the plication after the medical device is removed from the patient. In accordance with a further aspect, the tissue plicator may plicate tissue by mechanically clamping the tissue and/or may plicate the tissue at least in part by applying suction thereto. The system can be used to plicate tissue proximate the mitral valve of a patient. The plication can be formed temporarily or permanently.

    Abstract: A system for using a barbed tubular retainer in the treatment of mitral valve regurgitation by reshaping the mitral valve annulus using one or more plications of annular tissue each fixed by a retaining clip is described. The system includes four devices to achieve such percutaneous direct plication annuloplasty. The first is a crossing catheter. 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 placations in the subvalvular region of the mitral valve annulus. Fourth, a barbed tubular retainer deployed by the plication device in order to retain the plicated tissue in the plicated form. Alternatively, the fourth device is a retainer delivery catheter that enables delivery of a barbed tubular retainer that is attached to its distal end over the outside of the plication device.

    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.
