  • Patent number: 11013533
    Abstract: Systems and methods for delivering and retrieving a leadless pacemaker are described. A leadless pacemaker retrieval system includes a catheter system having a snare assembly to capture the leadless pacemaker. The catheter system includes sheaths extending distally from a shaft, and the snare assembly includes several snare legs, such as segments of snare loops, that extend from one sheath to connect to another sheath. The snare loops can have bights that connect to opposing sheaths to form a docking space between the legs of the snare loops and radially between the sheaths. The snare assembly is movable between an engaged position and a disengaged position by translating the snare legs within lumens of the corresponding sheaths. In the engaged position, the snare assembly tightens around the leadless pacemaker to allow the leadless pacemaker to be retrieved. Other embodiments are also described and claimed.

Two other wire segments are connected together at a proximal end and a distal end to form a second loop and are connected to the first two wire segments. The second loop is covered with a membrane to catch clots. The wire assembly may be compacted by retracting it within the elongated sheath, or expanded by extending it from the elongated sheath.

  • Patent number: 10111663
    Abstract: Devices and methods are disclosed for retrieving an implant or tissue anchor during the course of a percutaneous medical procedure. An implant is provided having a retrieval tether attached to it. The retrieval tether is attached to the implant on one end, and the proximal end of the tether can be threaded through an implant retrieval device. The retrieval device comprises an inner elongate body that is used to capture and secure the retrieval tether. The retrieval device also comprises an outer elongate body that may be configured to be advanced over the retrieval tether from a location remote from the implant (e.g., outside a patient's body) to contact and retrieve the implant after it has been deployed and/or implanted within a patient's body.

  • Patent number: 10064636
    Abstract: A method involves introducing a gathering part into a lumen in an ureteral access sheath in which is located calculus, wherein at least a part of the ureteral access sheath is located in an ureter in a living body. The gathering part is moved along the lumen in the ureteral access sheath in a forward direction toward the calculus, and then movement of the gathering part in the forward direction is stopped to position the gathering part adjacent the calculus so that the calculus is positioned between the distal end of the ureteral access sheath and the gathering part. The gathering part is expanded while the gathering part is positioned adjacent the calculus, and the calculus is then introduced into the gathering part.
