  • Patent number: 9872770
    Abstract: A device and method for repairing a mitral valve leaflet 2, 3. The device 10 includes a body 16 having an annular wall 18 and at least one aperture 22 through the annular wall 18. A deployment assembly 24 mounted on the body includes at least one grasping wire 28 arranged for sliding movement in the aperture 22. Movement of the deployment assembly 24 to a deployed position relative to the body causes a free end of the grasping wire 28 to project out from the annular wall 18 through the aperture 22, and movement of the deployment assembly to a retracted position relative to the body causes the free end of the grasping wire 28 to not project out from the annular wall 18. In the deployed position, the grasping wire 28 may grasp and gather tissue of the leaflet 2,3.

  • Publication number: 20170333189
    Abstract: An adjustment tool enables manipulation of a prosthetic anatomical device such as an annuloplasty ring. The tool includes a compression member which is operative for retarding rotation of the adjustment shaft to preclude inadvertent rotation thereof during use of the tool by the surgeon. A locking device is associated with the adjustment tool to enable the releasable attachment of the tool to the anatomical device during its adjustment by manipulation of the tool. The locking device is oriented into operative and inoperative positions by the engagement and disengagement of locking elements. A scale may be provided on the adjustment tool to assist a surgeon in determining the size or amount of adjustment to the size of the anatomical device during its adjustment.

  • Patent number: 9801717
    Abstract: Apparatus for use with a prosthetic heart valve includes a holder, to which the heart valve is releasably attached, and an elongated handle. The handle can be connected to the holder simply by pushing a distal end of the handle straight into a recess in the holder. After this has been done, the holder preferably releasable latches onto the handle, and the handle can also be rotated about its longitudinal axis to transmit torque to the holder (e.g., a rotatable portion of the holder). Rotation of such a rotatable portion of the holder can be used to deflect portions of the valve radially inward. This operation of a rotatable portion of the holder is preferably one-way only. The handle can be released from the holder at any time, and it can similarly be reconnected to the holder at any time.

  • Patent number: 9717547
    Abstract: An ablation catheter comprises: an elongated catheter body extending longitudinally between a proximal end and a distal end along a longitudinal axis; a distal member disposed adjacent the distal end, the distal member including an ablation element to ablate a biological member; one or more acoustic transducers disposed in the distal member and each configured to direct an acoustic signal toward a respective target ablation region and receive reflection echoes therefrom; and an acoustic redirection member disposed in the distal member to at least partially redirect the acoustic signal from at least one of the acoustic transducers toward a tissue target. The distal member includes a most-distal portion, a proximal portion, and a deflectable portion between the most-distal portion and proximal portion to permit deflection between the most-distal portion and proximal portion of the distal member. The transducers and redirection member are mounted on opposite sides of the deflectable portion.

  • Publication number: 20170143484
    Abstract: A stent for use in a prosthetic heart valve has a plurality of expandable and collapsible closed cells, a portion of which form an annulus section adapted for placement within the annulus of the native heart valve. Anchor features of the stent residing within at least some closed cells are adapted to engage tissue of the heart, including native valve leaflets, the sinotubular junction, or another implanted device when the prosthetic valve is implanted in the heart. The anchor features may help to retain the prosthetic valve in position, without interfering with the opening and closing of the valve leaflets. Furthermore, the anchor features may be configured to allow the stent to be resheathed into a delivery device after the portion of the stent with the anchor feature has expanded out of the delivery device.
