Abstract:
A bipolar snare (1) comprises an elongated tubular electrically insulating sheath (2), a pair of elongated flexible electrically conductive wires (3 & 4) disposed within the sheath, and an electrically insulating connector (7) disposed at the distal ends of the wires mechanically connecting the distal ends of the wires to form a loop (8) projecting from the distal end of the sheath. The wires (3 & 4) are provided with electrical insulation (9) covering all but a selected portion (10 & 11) of each of the wires. The device also includes a guide member (12) located within the sheath (2) and forming compartments for each of the electrically conductive wires, the guide member (12) being rotatable within the sheath. The guide member (12) is also set back from the distal end of the sheath (2) to an extent such that the whole of the loop (8) including at least part of the connector (7) is capable of being received within the sheath.
