Abstract: A scissor style vessel sealer having a first shaft interconnected to a first jaw by a pivot plate that pivotally couples the first shaft to the first jaw by the pivot and also by a spring that is secured at one end to the first shaft and an opposing end to the pivot plate at a location offset from the pivot and a second shaft connected to a second jaw and pivotally coupled to the first jaw by the pivot. The first shaft and the second shaft are then pivotable from a jaws open position to a jaw closed position. Any further application of force results in the first shaft pivoting relative to the first jaw so that the additional force is not transmitted to the jaws. The first shaft pivoting relative to the first jaw may actuate a button associated with the second shaft.

Abstract: A surgical device configured to cut a tissue of a patient can include a first jaw, a second jaw, a cutting blade, and a suction channel. The second jaw can be movably coupled to the first jaw such that the first jaw and the second jaw are moveable between an open position and a closed position. The cutting blade can extend from the second jaw toward the first jaw. The suction channel can be configured to draw the tissue towards the second jaw and to add tension to the tissue and improve one or more cutting capabilities of the surgical device.

Abstract: A manipulable portion of a catheter system advances out of a lumen of a catheter sheath at a distal end of a shaft, which is also within the lumen of the catheter sheath. The catheter system causes different advancement and retraction trajectories of a manipulable portion out of and into the lumen based at least upon different relative movements between the catheter sheath and the shaft. A projection and a corresponding receiver may be used to control relative positioning of the catheter sheath and the shaft, as well as to control positioning of the manipulable portion. The catheter system may control metering rates of a control element coupled to the manipulable portion during advancement and retraction of the manipulable portion. A control element of the catheter system has varying amounts of length outside a distal end of the catheter sheath during advancement and retraction of the manipulable portion.

Abstract: A method of creating an AV fistula between adjacent first and second vessels includes inserting a guidewire from the first vessel into the second vessel. Inserting a catheter including a proximal member and a distal member over the guidewire such that a distal tip of the distal member comes into contact with a selected anastomosis site. Moving the distal member and the proximal member together to clamp tissue surrounding the aperture between the distal face of the proximal member and a proximal face on the distal member. Applying energy to an active heating member on the proximal member to cut and form the aperture, and to weld the edges thereof in order to create a desired fistula between the two vessels. Using a passive heating member disposed on the distal member to create a heating gradient across a tissue contacting surface of the distal member.

Abstract: The recovery of an intact volume of tissue proceeds with a delivery cannula distal end positioned in confronting adjacency with the volume of tissue to be recovered. A tissue cutting and capture assembly formed of a plurality of metal leafs is deployed from the distal end of the delivery cannula. The tips of these leafs carry a pursing cable assembly, which is resistively heated by the passage of electrical current through the cable, attaining temperature level sufficient to thermally cut around and circumscribe the tissue volume. These pursing cables are tensioned to complete the envelopment of the tissue volumes by drawing the leaf tips together. An essential attribute of the disclosed apparatus is the confinement of the path of electrical conduction of constant current required to achieve tissue cutting to only those portions of the deploying and retracting resistively heated portion of the electrically conductive cutting and pursing cable that are in direct contact with tissue.

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.
