  • Patent number: 10751208
    Abstract: An implant delivery system includes a delivery catheter and a delivery mechanism slidably disposed in a lumen of the delivery catheter. The delivery mechanism includes an annular channel and a compressible annular bushing disposed within the annular channel. The annular bushing is configured for being placed between a compressive profile and an expanded profile. The implant delivery system further includes an implant coaxially disposed between the delivery catheter and the delivery mechanism. The delivery catheter lumen is sized to maintain an engagement element of the implant within the annular channel and to urge the annular bushing into the compressive profile. The implant constrains a distal tip of the delivery mechanism to assume a straight geometry. The distal tip is configured for assuming a curved geometry when the implant is deployed from the delivery catheter.
    Type: Grant

  • Patent number: 8974513
    Abstract: An implant assembly comprises an elongated pusher member, and an implantable device (e.g., a vaso-occlusive device) mounted to the distal end of the pusher member. The implant assembly further comprises an electrolytically severable joint disposed on the pusher member, wherein the implantable device detaches from the pusher member when the severable joint is severed, and a return electrode carried by the distal end of the pusher member (e.g., a coil disposed about the pusher member) in proximity to, but electrically isolated from, the severable joint. The implant assembly further comprises a terminal carried by the proximal end of the pusher member in electrical communication with the severable joint.
