Publication number: 20230293168Abstract: Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.Type: ApplicationFiled: May 26, 2023Publication date: September 21, 2023Inventors: Manouchehr A. Miraki, Bryan A. Janish, Kevin K. Dang

Patent number: 11707271Abstract: Disclosed are devices and methods for delivering several sutures accurately and simultaneously around the perimeter of an annular prosthetic device (prosthetic heart valve, annuloplasty ring, etc.) to secure the prosthetic device within a native heart valve region. Devices can comprise a proximal handle portion including an actuator and a distal suturing portion including several curved and straight needles arrayed around the shaft axis. The straight needles and the curved needles are configured to simultaneously guide a plurality of sutures through the native tissue and through the annular prosthetic device. The actuator can cause the straight needles to move axially relative to the curved needles and can also cause the curved needles to rotate, such that the motions are coordinated to simultaneously place all the sutures.Type: GrantFiled: February 10, 2022Date of Patent: July 25, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Kevin K.

Publication number: 20220161002Abstract: A clamping device for a shaft of a catheter can include a first member rotatably coupled to a second member. The first member can have an annular element defining a central lumen, the outer surface of the annular element having a non-circular cross-sectional profile, and the second member can define a bore into which the annular element extends, the bore having a non-circular cross-sectional profile. The device can move between a release state wherein the central lumen has a first diameter, and a clamped state wherein the central lumen has a second diameter less than the first diameter. When the clamping device is in the clamped state, the clamping device can engage an outer surface of a catheter shaft and when the clamping device is in the release state, the clamping device can be moved along a length of the catheter shaft.Type: ApplicationFiled: February 7, 2022Publication date: May 26, 2022Inventors: John X.

Publication number: 20220071619Abstract: A multiple-firing clip device includes a hollow shaft defining a lateral opening communicating with an environment and a distal shaft portion between the lateral opening and a distal end opening. A shuttle longitudinally moves on the shaft and comprises a shuttle body defining a lumen surrounding the shaft, a snare, and a snare-extender slide defining a snare track to form a snare travel path in which the snare is disposed from the body and through the track and a portion of the body. The slide moves along a given extent defining a slide distance and a distal end and movement of the slide to the distal end shortens the snare travel path to extend the snare portion through the lateral opening, through the distal shaft portion, and distally out from a distal side of the body longer than the given extent to secure a suture with the snare.Type: ApplicationFiled: November 16, 2021Publication date: March 10, 2022Inventors: Derek Dee Deville, Kevin W.
