摘要： An apparatus for thermal treatment of a tissue mass having an elongated housing having a proximal and a distal end and defining a longitudinal axis, and further including at least two electrodes supported at its distal end and mounted for rotation to facilitate entry and passage through a tissue mass. A drive shaft may be disposed within the elongated housing and operatively engageable with the electrodes for causing their rotational movement. The apparatus may include an electrode gear and a drive shaft gear in cooperative engagement whereby rotation of the drive shaft causes corresponding rotation of the electrodes. Preferably, a motor is operatively connected to the drive shaft causing its rotational movement. Desirably, the distal end of the electrodes are threaded. A method for thermally treating a tissue mass is disclosed.

摘要： A surgical system and associated method for sealing the passageway of a fluid-carrying vessel with a diameter up to 5 millimeters comprises an electrosurgical generator capable of delivering electrosurgical power, a surgical instrument electrically connected to the electrosurgical generator and adapted to transfer electrosurgical power from the electrosurgical generator to a pair of end effectors disposed at a distal end of the surgical instrument. The system also includes a power control circuit for controlling the delivery of radio frequency energy to the vessel through the end effectors, wherein the delivery of the radio frequency energy to the vessel comprises, raising the output current to a range below 1.75 Amperes RMS and the output voltage to a range below 135 Volts RMS. Radio frequency energy is applied to the vessel for a period of time while the power is held approximately constant. The flow of radio frequency energy is terminated when the impedance of the vessel being sealed reaches a predetermined level.

摘要： A bipolar electrosurgical instrument for clamping, grasping, manipulating, and sealing tissue includes first and second shafts each having a jaw member extending from a distal end thereof and a handle disposed at a proximal end thereof. The handle being operable to effect movement of the jaw members relative to one another from a first position wherein the jaw members are disposed in spaced relation relative to one another to a second position wherein the jaw members cooperate to grasp tissue therebetween. The bipolar instrument is connectable to a source of electrical energy having a first electrical potential connected to one of the jaw members and a second electrical potential connected to the other of the jaw members such that the jaw members are capable of selectively conducting energy through tissue held therebetween to effect a seal. Both the first and second electrical potentials are transmitted to the jaw members through the first shaft.

摘要： Apparatus and methods are provided for ablating body tissue using radio frequency (RF) energy. A catheter having a lumen for delivering fluid can be inserted into a patient's body. A porous member, which may be expandable, is attached to the distal portion of the catheter. The porous member defines an interior region in communication with the lumen, such that the interior region is capable of receiving electrolyte fluid delivered from the proximal portion of the catheter. An RF electrode is disposed in the interior region and is configured for coupling to a source of RF energy, whereby RF energy may be transferred from the electrode to selected tissue areas in a patient's body via electrolyte fluid delivered through the lumen and into the interior region of the porous member.
