摘要： A coagulation system is provided for use in biological tissue. The coagulation system includes a handle, a radiofrequency (RF) generator, and an electrode array. The electrode array includes two or more pair of bipolar electrodes slideably coupled in channels of the handle. The bipolar electrodes electrically couple to the RF generator, and the electrode array is configured to deliver a balanced energy density in a target volume of the biological tissue. The balanced energy density delivered by the electrode array results in thermal coagulation necrosis of a rectangular volume of biological tissue.

摘要： Methods for performing coagulation necrosis of biological tissue are provided. The methods include configuring electrode arrays to provide balanced energy density in target tissue volumes using two or more pair of electrodes. The electrode array configuration includes at least one of irregular spacing between one or more pairs of electrodes and one or more electrode diameters. The methods further include deploying each electrode of an array at a selected depth in the target tissue volume in accordance with the configuration. Energy is then delivered to the target tissue volume using power sources coupled to the electrodes. The methods control power delivery in response to at least one of elapsed time of delivery, temperatures of the target tissue volume, and impedance levels in the target tissue volume to provide balanced or uniform energy throughout the target tissue volume. The methods generate planes of coagulated tissue.

摘要： 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. The energy director guide includes a series of channels that configure the energy directors to provide approximately uniform power distribution or current density through a target tissue volume or plane. The spacing among the channels of the energy director guide varies according to the total number of energy directors received in the energy director guide so that relative spacing among the center-most channels is largest and relative spacing among the end-most channels is smallest. The energy director guide secures a selected position of each of the energy directors in the target tissue volume.

摘要： An apparatus, and method for endometrial ablation by heating an inflation medium within a distensible bladder positioned within a uterus of a patient. The apparatus comprises an elongate tubular member, a handle, a distensible bladder and a heating element disposed within said distensible bladder. The system includes a controller configured for providing and regulating electric current to the heating element. The controller also includes a pressure sensor for regulating the pressure in the distensible bladder. Pressure and temperature displays and other operator controls are located on the controller unit. The method for performing endothelial ablation comprises inserting the distensible bladder and a portion of the tubular member into a uterus of a patient. The inflation medium within the distensible bladder is heated by providing electric current to the resistive wire of the heating element. The inflation medium within the distensible bladder is heated to a desired temperature and temperature and pressure within the distensible bladder are maintained for a desired time interval. The distensible bladder is then deflated and removed from the uterus.
