  • Patent number: 10434306
    Abstract: A device for extracting an elongated implanted structure from an obstruction within a vessel of a patient includes an inner sheath assembly and an outer sheath assembly. The inner sheath assembly includes an inner sheath and a tip, each having a passageway therethrough for receiving the implanted structure. The tip is configured for cutting and/or disrupting the implanted structure from the obstruction. The outer sheath assembly includes an outer sheath and a tip, each having a passageway therethrough for receiving the inner sheath assembly. The outer surface of this tip includes a plurality of raised elements circumferentially disposed therealong. The raised elements are configured for stabilizing the tissue of the vessel as the device is advanced through the vessel.

  • Patent number: 9936965
    Abstract: A snare for deployment or retrieval of an implantable medical apparatus. The snare includes a shaft, and a tip distal of the shaft. The tip includes an extendable member capable of self-centering the implantable apparatus during a deployment or retrieval. The extendable member is selectively receivable in the tip, distally extendable from the tip, and rotatable relative to the tip. An activatable handle is engaged with the shaft. A wire has an end engaged with the handle and an end engaged with the tip. Upon activation, the wire is urged in a proximal direction, resulting in a flexure of the tip. An elongated mechanism has a proximal portion engaged with the handle, and a distal portion engaged with the tip extendable member. The elongated mechanism is configured for selectively controlling the receiving, deploying, and rotating of the extendable member.

  • Patent number: 9155878
    Abstract: A device for preparing an elongated implanted medical apparatus, such as a cardiac lead, for extraction from the body of a patient. The device includes a first handle and a second handle. At least the first handle has a surface for receiving the implanted apparatus therealong. A wire member having a first end and a second end is positioned to span a distance between the surface of the first handle, and the second handle. The wire member first end is removably engaged with the first handle, and the wire member second end is removably engaged with the second handle. The wire member is sized and arranged to enable the wire member to be wound around a length of the implanted apparatus to facilitate extraction of the apparatus with a lead extraction device.
