  • Publication number: 20190247049
    Abstract: An apparatus for deployment of a hemostatic clip includes a handle assembly, a shaft connected to a distal portion thereof and a clip assembly releasably coupled to a distal portion of the shaft. The clip assembly includes clip arms and a capsule cooperating with the clip arms to provide a first user feedback indicating a decision configuration of the clip assembly. In addition, the apparatus includes a control wire including a ball connector, the control wire extending from the handle assembly and coupled to the clip assembly by the ball connector to maintain the clip assembly coupled to the shaft, wherein the ball connector is detachable from the clip assembly to provide a second user feedback indicating separation of the clip assembly.

  • Patent number: 10307169
    Abstract: A medical device includes a clip having first and second arms biased toward an open configuration; a control wire removably connected to the clip, the control wire configured to control movement of the clip between an open configuration and a closed configuration; a separable yoke connecting the control wire to the clip, the yoke configured to be separated by a predetermined force applied by the control wire so that, when the yoke is separated, the control wire and the yoke uncouple from the clip; an elongated sheath housing the control wire; a handle coupled to the elongated sheath; and an actuator coupled to the control wire and configured to open the clip arms, close the clip arms and uncouple the clip from the control wire.

  • Patent number: 10293137
    Abstract: An introducer (10) with a steerable distal tip section (17) is disclosed. The steerable distal tip section may comprise an articulation support member comprising a laser-cut pattern of symmetrical elongated apertures in which the shape of each aperture is defined by at least three radii, a central radii being the largest and two end radii being smaller. This pattern of apertures can minimize ovaling of the cross-sectional shape of introducer shaft over the length of the deflectable section. The introducer can articulate in multiple planes. A tension pull wire can allow the introducer to resist directional bias.

  • 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: 10058348
    Abstract: A method of gathering tissue of a heart valve leaflet 2 may include inserting an elongated catheter assembly 12 to a position adjacent the heart valve leaflet, the catheter assembly including a capture tool 22 and a tissue support member 30. The capture tool 22 and the tissue support member 30 may each be independently moveable between a retracted position and an extended position. Partially retracting the capture tool 22 with the tissue support member 30 in the extended position gathers tissue 15 of the heart valve leaflet 2 between the capture tool and the tissue support member. A clip 55 may then be applied from the catheter assembly 12 to the gathered tissue 15 to hold the tissue substantially in a gathered configuration.
