Abstract: An end effector for an electrosurgical instrument includes a pair of opposing first and second jaw members movable between an open position in which the jaw members are disposed in a spaced relation relative to one another, and a closed position in which the jaw members cooperate to grasp tissue therebetween. A first sealing electrode is located on the first jaw member, and a second sealing electrode is located on the second jaw member. One or more stop members are disposed on the sealing electrodes, the one or more stop members being formed of a compliant material such that they are capable of deforming when the jaw members are moved to their closed position with tissue grasped therebetween.

Abstract: A device for morcellating tissue within a body cavity of a patient comprises a stationary tube (8) having a distal end portion, and a bipolar electrosurgical electrode assembly (13) located at the distal end of the tube. The electrosurgical electrode assembly (13) comprises first and second electrodes (14, 16) separated by an insulation member (15). When an electrosurgical cutting voltage is applied to the electrode assembly (13), and relative movement is initiated between the tube (8) and the tissue, a slug of severed tissue is formed within the tube such that it can be removed from the body cavity of the patient. The bipolar electrosurgical assembly (13) has a first circumferential region (A) and a second circumferential region (B), the first circumferential region (A) being longer than the second circumferential region (B).

Abstract: A bipolar snare including an elongated tubular electrically insulating sheath, a pair of elongated flexible electrically conductive wires disposed within the sheath, and an electrically insulating connector disposed at the distal ends of the wires mechanically connecting the distal ends of the wires to form a loop projecting from the distal end of the sheath. The wires are provided with electrical insulation covering all but a selected portion of each of the wires. The device also includes a guide member located within the sheath and forming compartments for each of the electrically conductive wires, the guide member being rotatable within the sheath. The guide member is also set back from the distal end of the sheath to an extent such that the whole of the loop including at least part of the connector is capable of being received within the sheath.

Abstract: A body fluids drainage system includes a urinary catheter, a drainage collection bag, and a connection member connected between the urinary catheter and the drainage collection bag. The connection member houses a valve element formed from a sheet of material and projecting a coherent plane. The valve element defines a longitudinal direction extending between a connecting portion and a flap portion and a recess formed on a periphery of the valve element between the connecting portion and the flap portion.

Abstract: The device (1) for providing anti-reflux has a valve element (9) formed from a sheet-shaped material blank. The valve element includes a connecting portion and a flap portion. Retaining means (10a,10b) for retaining the valve element are integral with the device. The connecting portion includes engagement means formed integrally with the valve element for engagement with the retaining means, the valve element projecting a coherent plane.
