Abstract: An insertion catheter for a circulatory support catheter having a circulatory support device carried by an elongate flexible catheter shaft. The insertion catheter comprises a tubular body with a distal portion configured to axially movably receive the circulatory support device. A diameter of the distal portion is greater than a diameter of a mid portion of the tubular body. The insertion catheter may be inserted into an introducer sheath for delivery of the MCS device. A distal end of the insertion catheter may be located distally of a distal end of the introducer sheath and distally of the arterial bifurcation. The distal portion of the insertion catheter containing the MCS device may be located distally of the bifurcation, with a distal end of the MCS device slightly offset from the distal end of the tubular body.

Abstract: In one representative embodiment, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. The spacer body can be configured to extend radially outwardly as the spacer body extends away from the distal end toward the proximal end. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.

Abstract: In one example, an implantable prosthetic device comprises a spacer body portion configured to be disposed between native leaflets of a heart, and an anchor portion configured to secure the native leaflets against the spacer body portion. The prosthetic device can be movable between multiple configurations. A size of the spacer body is configured to be adjusted after the spacer body is placed between the native valve leaflets and the pair of anchors are placed against the ventricular surfaces of the native heart valve leaflets. A delivery apparatus can have a first shaft and a second shaft, wherein movement of the first shaft relative to the second shaft moves the anchor portion relative to the spacer body.

Abstract: Valve repair systems and clips attachable to one or more leaflets of a heart valve. The systems and clips can have an elongated member and a pair of arms. The pair of arms are movable between an open position and a closed position. The pair of arms are movable from the open position to the closed position to pinch the one or more leaflets of the heart valve between the pair of arms and the elongated member.

Abstract: Systems and methods are disclosed for use with a valve of a heart. An implant (100) includes a wing (120); a flexible frame (124); and a pair of anchor receivers (150). A pair of shafts (660) are transluminally advanced through a catheter (40), while the shafts are each engaged with a respective anchor receiver (150), to deploy the implant out of the catheter such that the wing extends away from the anchor receivers and over a first leaflet of the valve and toward an opposing leaflet of the valve, with a contact face (122) of the wing facing the first leaflet. A pair of drivers (70) secure the implant using a pair of anchors (30) to anchor each anchor receiver to tissue at respective sites of the heart. Other implementations are also described.
