摘要： A method and an apparatus (14) is disclosed for delivering controlled heat to perform ablation to treat the benign prosthetic hypertrophy or hyperplasia (BPH). According to the method and the apparatus (14), the energy is transferred directly into the tissue mass (6) which is to be treated in such a manner as to provide tissue ablation without damage to surrounding tissues. Automatic shutoff occurs when any one of a number of surrounding areas to include the urethra (2) or surrounding mass or the adjacent organs (6) exeed predetermined safe temperature limits. The constant application of the radio frequency energy over a maintained determined time provides a safe procedure which avoids electro-surgical and other invasive operations while providing fast relief to BPH with a short recovery time. The procedure may be accomplished in a doctor's office without the need for hospitalization or surgery.

摘要： Improved systems and methods for effecting lesion formation within human tissue via radio frequency (RF) ablation. An RF generator system is provided which automatically regulates an amount of RF energy delivered to an electrode deployed within the area of tissue to be ablated. The RF energy is delivered in such a manner that the temperature of the tissue in the area to be ablated is increased in a controlled manner to a target value over a first selected period of time and, thereafter, maintained at the target value for a second period of time. Maximum lesion formation may be achieved through the use of systems and methods in accordance with the present invention.

摘要： A dual-channel RF power delivery system for applying RF energy to dual electrodes (26) of an RF ablation device with independent control of the power level, frequency, phase, and time duration of the RF energy applied to each electrode to more accurately control the ablation of a target tissue. The power delivery system supplies a first controlled RF signal having a first power level, frequency, phase, and time duration to the electrode (26) of a first flexible stylet (18) and a second controlled RF signal having a second power level frequency, phase, and time duration to the electrode (26) of a second flexible stylet (19). The difference btween the first and second power levels and the temperature of the tissue between the first stylet (18) and second stylet (19) are monitored to control the ablation of the target tissue. The supply of the first RF signal is terminated when the monitored temperature of the first stylet (18) exceeds a first predetermined value and the supply of the second RF signal is terminated when the monitored temperature of the second stylet (19) exceeds a second predetermined value.

摘要： A method for treating tissue of a mammalian body in which the conductivity of the tissue is characterized. The amount of a conductive liquid to supply to the tissue is determined as a function of the conductivity of the tissue and injected into the tissue over an interval of time. Electromagnetic energy is supplied to the tissue to form a lesion in the tissue. A computer-readable memory and a radio frequency generator and controller utilizing such method are further provided.

摘要： An anastomosis catheter is provided with internally mounted cam pieces holding a plurality of curved needles adjacent apertures in the side of the catheter is provided. The curved needles are attached to lengths of suture material which are installed to run along the outer surface of the central cam pieces to their distal end, where they reverse back along the inner core of the catheter. When the central cam pieces are withdrawn, and moved proximally, the cam surface forces the curved needles out the associated apertures. As the catheter is deployed in a hollow organ, such as a human urethra, the curved needles, as they are deployed, grasp the end of the urethra, which then can be held in position for suturing to the bladder. The other end of the suture materials could have straight needles attached to them to facilitate attaching the urethra to the bladder. A passive fixation device is also provided, defined by a generally elongated body with proximal and distal ends, and a connecting member to connect the two, is used for the anastomosis of body lumens without sutures. The proximal and distal ends are non-deployed in a non-deployed position, and are deployed in a deployed position. While in the non-deployed positions, the passive fixation device is inserted into one or more body lumens. After insertion, both the proximal and distal ends are deployed and become expanded. One end is first deployed, and then the other. The deployed proximal end becomes retained in a first lumen, and the deployed distal end becomes retained in a second lumen.

摘要： A transurethral needle ablation device (21) comprising a bridge (22) having proximal and distal extremities and having a passage (236) therein extending from the proximal extremity to the distal extremity. A sheath (23) having proximal and distal extremities (42, 43) is secured to the bridge (22) and has a passageway (44) therein in communication with the passage (236) in the bridge. The sheath (23) is sized so that it can enter the urethra and has a length so that when its distal extremity (43) is in the vicinity of the prostate, the proximal extremity (42) is outside the urethra. A disposable needle assembly (26) having proximal and distal extremities is removably mounted in the passage (236) in the bridge (22) and extends through the passageway (44) in the sheath (23). The needle assembly (26) includes at least one needle electrode (101) and an insulating sleeve (91) coaxially disposed on the needle electrode. The proximal extremity of the needle assembly (26) is caused to be moved sideways at an angle with respect to the the longitudinal axis to face the urethral wall. A mechanism is carried by the proximal extremity of the needle assembly (26) and the bridge (22) for causing advancement of the needle electrode (101) and the insulation sleeve (91) thereon through the urethral wall and into the target volume in the tissue of the prostate.
