  • Patent number: 8444661
    Abstract: Devices, systems and methods for removing foreign bodies within a body lumen are disclosed. An unfolding balloon catheter may include an elongated shaft having an intussuscepting balloon that can be actuated within a body lumen to capture and retrieve an intravascular device. The balloon may be configured to radially and/or axially expand when inflated, enveloping the intravascular device. In certain embodiments, the balloon may be formed by folding the ends of a distensible member inwardly, and then bonding the ends of the distensible member to the elongated shaft to form an expandable sleeve. An adhesive layer located along a portion of the elongated shaft may be used to temporarily secure the balloon to the elongated shaft.

  • Patent number: 6878151
    Abstract: Compositions comprising devices for retrieving objects from a subject, for example the subject's vasculature, are described. In particular, devices including a catheter shaft having a lumen through which a core wire extends are provided. Proximal and distal junction members are disposed around the core wire and at least one junction member is permanently and slidably attached to the core wire. In addition, the device includes a retrieval element as well as a stop element that is attached to the core wire distal to the catheter shaft. Also described are methods of making and using these devices.
