  • Patent number: 12127743
    Abstract: An implant can be implanted in an aneurysm to cause thrombogenesis within the aneurysm's sac. The implant can include a braid that can extend across the aneurysm neck and anchor to aneurysm's walls at least in the proximal portion of the aneurysm sac. The implant can further include a dome feature configured to press into aneurysm walls near the aneurysm's dome and facilitate securement of the braid across the aneurysm's neck. The braid at the aneurysm's neck and the dome feature can be joined or constricted at a junction, for instance with a radiopaque band. The dome feature can include a braid, embolic coil, and/or wire frame. The braid can be inverted based on a heat-set predetermined shape, where several predetermined shapes are suitable.

  • Patent number: 12011171
    Abstract: Disclosed herein are various exemplary systems, devices, and methods for inhibiting premature implant deployment. The delivery member can include a body including a lumen extending therethrough, the body including a compressed distal portion. The delivery member can include a pull wire extending through the lumen. The pull wire can include a pull wire portion that extends radially to abut a sidewall of the body to provide frictional resistance against the body. The pull wire can be positioned to secure the implantable medical device to the delivery member, and the pull wire portion can be effective to inhibit premature detachment of the implant by inhibiting proximal translation of the pull wire due to the frictional resistance provided by the pull wire portion against the body.

  • Patent number: 11963672
    Abstract: An endoscopic snare net comprises a net engaging a loop, such as by weaving the loop through a mesh of the net, and a tube having a lumen through which the net and loop may be extended and withdrawn by a control wire. The loop has one or more corners or a collared, free-floating slip tether or both thereof, which prevent the net from sliding free of the loop as the loop is retracted into the lumen of the tube, even if the loop is over-extended beyond the end of the tube.
