The energy delivery system includes an energy source and an electrode array. The electrode array includes bipolar electrodes positioned so a first spacing between a pair of adjacent electrodes is different relative to a second spacing between at ... 08/03/06 - 20060173453 - Minimal invasive endoscopic methods and apparatus for harvesting blood vessels A blood vessel in a patient is severed by inserting a shaft through an incision in the patient, the shaft carrying first and second clamps. The first and second clamps are closed against the vessel in closely adjacent relationship to one another. Thereafter, the clamps are moved in generally opposing ... 08/03/06 - 20060173452 - Laparoscopic bipolar electrosurgical instrument A laparoscopic bipolar electrosurgical instrument (10) for sealing tissue includes a handle (14) having an elongated tube (13) affixed thereto. The tube includes first (15) and second (16) jaw members having electrically conductive sealing surfaces (39, 40) attached to a distal end (12) thereof which are movable from a first ... 07/27/06 - 20060167451 - Medical instrument including an end effector having a medical-treatment electrode A medical instrument includes a flexible sheath and an end effector. The sheath has a distal end. The end effector is attached to the sheath proximate the distal end and is insertable into a patient. The end effector includes opposing and retroflexed first and second jaws and includes at least ... 06/29/06 - 20060142757 - Apparatus and method for tissue resection A tissue ablation system is described that generates a uniform avascular plane of coagulated tissue to aid in the bloodless or near-bloodless resection of various biological tissues from a variety of organs. The tissue ablation system includes an energy director guide and two or more sets of bipolar energy directors. ... 04/20/06 - 20060084974 - Surgical clamp A novel surgical clamp having a pair of jaws, which may be used to ablate or create leisons in tissue. In embodiment, the jaws have an articulated position wherein the jaws are separated and not parallel to one another, an opened position wherein the jaws are separated and substantially parallel ... 04/13/06 - 20060079890 - Bilateral foot jaws The present disclosure relates to a surgical instrument which includes a drive rod assembly having a hollow shaft portion. A central shaft is slidably disposed in and axially aligned with the hollow shaft portion. The instrument may further include a handle assembly coupled to hollow shaft portion and the central ... 03/23/06 - 20060064085 - Articulating bipolar electrosurgical instrument A bipolar electrosurgical instrument has a pair of pivotable juxtaposed jaw members and a locking mechanism operatively associated with a second of the jaw members. The locking mechanism has a first position engaged with the second jaw member for preventing movement of the second jaw member between an axially aligned ... 03/09/06 - 20060052776 - Electrosurgical probe The invention relates to an electrosurgical probe, in particular for electrocoagulation, comprising a handle and a shaft, the shaft being joined to the handle and having at least two electrodes offset from each other in the axial direction of the shaft, with one electrode closer to the handle forming a ... 02/09/06 - 20060030849 - Methods and apparatus for coagulating and/or constricting hollow anatomical structures An energy delivering probe is used for thermally coagulating and/or constricting hollow anatomical structures (HAS) including, but not limited to, blood vessels such as perforator veins. The probe includes a shaft and at least two electrodes where at least one of the electrodes has a generally spherical or toroidal geometry. ... 02/02/06 - 20060025766 - Energy based partial circumferential hemorrhoid repair device An energy based partial circumferential hemorrhoid repair device including an actuator assembly, and an energy based partial circumferential hemorrhoid repair device head assembly operatively connected to the actuator assembly, wherein the head assembly includes a proximal electrode assembly and a distal electrode assembly, and further wherein at least one of ... 01/05/06 - 20060004355 - Medical instrument for electrosurgery A medical instrument for electrosurgery comprises a tubular shaft having a distal end and a proximal end, at least one jaw part arranged at the distal end of the shaft and movable relative to the tubular shaft about a pivot axis, at least one electrode arranged at the at least ... 12/22/05 - 20050283151 - Surgical instrument A bipolar coagulating instrument includes a blade-like electrode assembly comprising an upper planar face and a lower planar face separated by an intermediate portion of insulating material therebetween.
