  • Publication number: 20230126785
    Abstract: A guiding sheath has a braided layer for improved deflection characteristics and ring electrodes for electrical sensing, mapping and visualization, wherein lead wires for the ring electrodes are passed through lumened tubing position under the braided layer in a proximal portion of the guiding sheath shaft and above the braided layer in a distal portion of the guiding sheath shaft. Moreover, the hemostatic valve includes an improved friction ring with air vents to reduce the risk of air being introduced into the valve.

  • Patent number: 10758351
    Abstract: A delivery device for a collapsible prosthetic heart valve includes an operating handle and a catheter assembly. The operating handle may include a housing defining a movement space therein, a carriage assembly moveable in a longitudinal direction within the movement space, a deployment actuator coupled to the housing and rotatable relative to the housing, and a coupling assembly rotationally fixed to the deployment actuator. The catheter assembly may include a first shaft around which a compartment is defined and a distal sheath operatively connected to the carriage assembly. Movement of the carriage assembly in the longitudinal direction in the movement space may move the distal sheath between the closed condition and the open condition. The coupling assembly may have an engaged position in which rotation of the deployment actuator moves the carriage assembly, and a disengaged position in which rotation of the deployment actuator does not move the carriage assembly.

  • Patent number: 10660756
    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.

  • Patent number: 10603169
    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: 10405869
    Abstract: A device 10 for gathering tissue in a patient includes an elongated catheter 14 and a capture assembly 13 at a distal portion of the catheter. The capture assembly has a closed side 18 and a door 20 rotatable between an open condition and a closed condition. The closed side 18 of the capture assembly 13 and the door 20 in the closed condition may collectively define a tissue capturing compartment 19. Movement of the door 20 from the open condition to the closed condition adjacent the tissue may capture a portion 44 of the tissue in the tissue capturing compartment 19. A clip may then be applied from the capture assembly 13 to the captured tissue 44 to hold the tissue substantially in a gathered configuration.

  • Patent number: 10265173
    Abstract: A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.

  • Patent number: 10028834
    Abstract: An adjustable prosthetic anatomical holder system may include an adjustable annuloplasty ring, a ring holder, and a positioning handle. The adjustable annuloplasty ring holder facilitates placement and adjustment of the annuloplasty ring during a cardiac surgical procedure. An optional positioning handle holds the adjustable annuloplasty ring during placement and suturing of the ring. The ring holder is constructed from two members that are slidably fit together in telescopic arrangement to accommodate adjustment of the ring size.
