摘要： A medical device (20) which includes an elongate probe member (22) sized to be able to enter a urethra of a female human body and having a length so that when the distal extremity (22b) is disposed in the vicinity of a target volume of tissue surrounding the urethra the proximal extremity is outside of the urethra. The elongate probe member (22) has a passage (31) extending from the proximal extremity (22a) to the distal extremity (22b). At least one tubular needle (41) is disposed in the passage (31) and has first and second extremities (41a, 41b) and a flow passageway (42) therein extending longitudinally from the first extremity (41a) to at least one opening (43) provided in the second extremity (41b) of the at least one tubular needle (41). A control handle (61) is secured to the proximal extremity (22a) of the elongate probe member (22) for causing movement of the at least one tubular needle (41) in the passage (31). A guide passageway (58) causes movement of the at least one tubular needle (41) through a curved path extending at an angle to the longitudinal axis (27). A supply assembly (96) is carried by the proximal extremity (22a) of the elongate probe member (22) and is in communication with the flow passageway (42) of the at least one tubular needle (41) for introducing an agent into the flow passageway (42). A method for use of the device (20) is 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 When the central cam pieces are withdrawn, and moved proximally, the cam surface forces the curved needles out the associated apertures.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 medical probe device comprising a catheter having a stylet guide housing with at least one stylet port in a side thereof and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. The stylet guide housing has an optical viewing means positioned for viewing the stylet and adjacent structure which includes a fiber optic channel means for receiving a fiber optic viewing device. The fiber optic channel means can include a guide port means for directing longitudinal movement of a fiber optic device with respect to the stylet guide means in a viewing zone and a flushing liquid channel in the stylet guide housing having an exit port positioned to direct flushing liquid issuing therefrom across the end of a fiber optic device when positioned in the viewing zone. The optical viewing means can comprise a viewing window positioned in the stylet guide housing for viewing the stylet when it is directed outward from its respective stylet port. The optical viewing means can include a fiber optic channel in the stylet guide housing for receiving the a fiber optic viewing device and aligning the viewing end thereof with the viewing window. Windowed devices can include a flushing liquid channel in the stylet guide housing having an exit port positioned to direct flushing liquid issuing therefrom across a surface of the viewing window.

摘要： A method and an apparatus 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, the energy is transferred directly into the tissue mass which is to be treated in such a manner as to provide tissue ablation without damage to surrounding tissues. Automatic shut-off occurs when any one of a number of surrounding areas to include the urethra or surrounding mass or the adjacent organs exceed predetermined safe temperature limits. The constant application of the radio frequency energy over a maintained determined time provides a safe procedure which avoids electrosurgical 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.
