The first wire defines a first region susceptible to electrolytic disintegration, by passing an electric current through it, contiguous to a the first attachment point. Similarly, and the second wire defines a second region susceptible to electrolytic disintegration, by passing an electric current through it, contiguous to the second attachment point. Also, there is a separately controllable electric supply for the first and the second wire, so that the first wire may be disconnected from the medical device, without disconnecting the second wire.

  • Publication number: 20130338658
    Abstract: A surgical cautery device, system, and method of use may apply bipolar and/or sesquipolar electrocautery to target tissue via a pair of instruments with other primary surgical functions. The surgical cautery device and system may include first and second elements capable of forming an electrical circuit. The second element may be independently positionable with respect to the first element. The first and second elements may also include a surgical component with an independent surgical function. Exemplary surgical components include a rotary blade, a cutting tool, a grasper tool, a micro-scissors tool, a micro-grasping forceps tool, a dissector, a micro-dissector, curette, and a suction cannula. On some occasions, one of the surgical components may be interchangeable with another surgical component.

  • Publication number: 20130317492
    Abstract: A medical for removing tissue from a patient includes an elongated probe with a working end. A pair of jaws is provided at the working end. The jaws may be closed for cutting and treatment of the tissue. Cutting may be effective through a sharpened cutting blade, and RF cutting blade, and similar cutting edges. The tissue may be remodeled using heat generated from passive heating elements on the jaws, active heating elements on the jaws, a PTCR heating element carried by the jaws, or resistive heaters on the jaws.

  • Publication number: 20130296838
    Abstract: Thermal, Electrosurgical and Mechanical modalities may be combined in a surgical tool. Potentially damaging effects in a first modality may be minimized by using a secondary modality. In one example, thermal hemostasis may thus help electrosurgical applications avoid the adverse tissue effects associated with hemostatic monopolar electrosurgical waveforms while retaining the benefits of using incising waveforms.

  • Publication number: 20130281998
    Abstract: A catheter-based device tracks over a guidewire which has been placed from a first blood vessel into a second blood vessel. The distal tip of the catheter is advanced into the second vessel while a proximal member remains in the first vessel. Matching blunt tapered surfaces on each of the distal tip and the proximal member are clamped together, with adjacent walls of each vessel between them, after which a known, controlled pressure is applied between the two surfaces. Heat energy is then applied to the blunt surfaces for approximately 1-30 seconds to weld the walls of the two vessels together. After coaptation of the vessel walls, the heat is increased to then cut through the vessel walls to create a fistula of the desired size.

  • Patent number: 8540707
    Abstract: Template systems and methods for various procedures (e.g., tissue ablation procedures) are disclosed. An exemplary template system comprises a track having at least one suction port. The at least one suction port anchors the track to a tissue after the track is positioned adjacent a target area. The template system may further comprise a transducer operatively associated with the track. Exemplary transducers include imaging transducers and ablating transducers. The transducer is guided by the track adjacent the target area while the transducer is moved along the track for a procedure. One or more umbilical may provide a conduit to the track and/or transducer so that the template system may be positioned in a patient's body (e.g., for a procedure on the patient's heart) and operated remotely by a physician or other user from outside of the patient's body.

  • Patent number: 8475444
    Abstract: A hemostatic surgical blade is described which is formed of five symmetrically disposed layers. A martensitic stainless steel core is provided with oppositely disposed faces which are bonded to hard pure copper thermal transfer layers which, in turn, are supported by buttressing layers of austenitic stainless steel. The blade is heated by a blade heater circuit which is provided as a flexible circuit carrying one or more resistor heaters and associated leads supported by a polyimide substrate. A thermally conductive and electrically insulative adhesive is used to bond the flexible circuit to a blade blank. The system employs a multi-lead cable which is removable from an instrument handle. One blade embodiment involves an elongate stem for accessing body cavities and another embodiment incorporates a controller function within an instrument handle.
