Abstract: A medical device includes an insertion tube, having a longitudinal axis and having a distal end adapted for insertion through a body passage into a cavity within a body of a patient. An electrode is located on the distal end of the insertion tube and is configured to contact tissue in the cavity. A resilient member is contained within the distal end of the insertion tube and is configured, when unconstrained, to cause the distal end to bend away from the longitudinal axis in a curved shape and to straighten toward the longitudinal axis when subjected to a force.

Abstract: A conforming electrode for delivering ablative energy to tissue generally includes a plurality of flexible metal tubes, each having a longitudinal axis, a proximal end, and a distal end. The flexible metal tubes are arranged in a bundle with their longitudinal axes aligned parallel to each other. In addition, the flexible metal tubes are electrically coupled to a conductor for transferring ablative energy to the flexible metal tubes. The conductor may be a loop around the flexible metal tubes and to which the flexible metal tubes may be secured. The proximal ends of the flexible metal tubes may be secured to the distal end of a catheter shaft.

Abstract: Shape memory tissue engagement elements (15) are created using shape memory alloys or shape memory (SM) composite sheets (33, 36) with one or more SM material sheets (20, 32). Arrays of the tissue engagement elements may then be inserted or molded into flexible base materials forming pads for tissue engagement. In certain embodiments, the composite sheets incorporate two SM material layers (20, 32) having differing transition temperatures to allow activation of one layer for tissue engagement and activation of the second layer for tissue release. In exemplary embodiments, insertion of interconnected tissue engagement elements (46) into a base layer (19) with slots (48) provides a completed pad array. In alternative exemplary embodiments, vacuum forming of composite sheets (51) with cutting of corrugated sides (53) to form tissue engagement elements allow production of complete arrays of tissue engagement elements. Overmolding the arrays with a flexible base material (19) provides a completed pad.

Abstract: A bipolar forceps is provided. The bipolar forceps includes a housing having a shaft including an electrically conductive distal end. A drive assembly is operable to reciprocate an actuation tube within the shaft. A portion of the actuation tube is electrically conductive. An end effector assembly operatively connects to the shaft and includes a pair of first and second jaw members biased in an open configuration. The first and second jaw members are pivotable about a living hinge. Distal reciprocation of the actuation tube causes each of the jaw members towards one another about the living hinge. One of the jaw members is in electrical communication with the distal end of the shaft and the other jaw member is in selective electrical communication with a distal end of the actuation tube such that when the jaw members are in a closed configuration a closed loop electrical circuit is formed.

Abstract: A device and method suitable for remodelling the internal surface of a hollow vessel at least partially occluded by a mass is provided. The device comprises an elongate body having a distal end and a proximal end, the distal end comprising a tip portion located at the distal terminus of the body, and at least one heating element located proximally to the tip portion within the distal end. The at least one heating element is configured to be greater in dimension proximally than distally and thereby tapers towards the distal end. Furthermore, the at least one heating element is arranged so that it can be deployed outwardly from the body of the device and in so doing exert an expansion force on the hollow vessel. The at least one heating element is capable of delivering sufficient energy to remodel the internal surface, and if necessary caused localised ablation, of the hollow vessel without inducing closure of the hollow vessel.
