    Abstract: The device and method of the present invention is a medical probe device which has an elongated guide having a longitudinal axis, and a handle and probe end, the guide defining a port at its probe end. The device also has a flexible, resilient tape stylet, movably mounted relative to said longitudinal guide for movement along the longitudinal axis, having two opposed side portions, a proximal end, a piercing end and a sharpened tip on said piercing end, and a deflector, housed within said longitudinal guide, which deflects said flexible resilient tape stylet through said port. A method of moving a stylet through an elongated guide to an outlet port is also disclosed. A method of manufacturing a flexible resilient tape stylet of the present invention is also disclosed.

    Abstract: According to the present invention, an anastomosis catheter 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 When the central cam pieces are withdrawn, and moved proximally, the cam surface forces the curved needles out the associated apertures.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.

    Abstract: A method of this invention for treating body tissues containing cancerous cells or non-malignant tumors with RF ablation, alone or in combination with systemic or localized chemotherapy comprising introducing a stylet comprising an electrode surface and a sleeve longitudinally moveable thereon into the vicinity of the body tissues, retracting the sleeve from a portion of the electrode surface, and supplying RF power to the electrode surface sufficient to heat the tissue to a temperature of above about 45.degree. C. for a time to cause reduction of tissue mass in the vicinity of the electrode. The RF power supplied to the electrode surface is sufficient to effect a desiccated fluid diffusion barrier capsule surrounding the body tissue being treated. The stylet can include a hollow tube having fluid distribution ports therein, and the method can include the step of passing fluid through one or more distribution ports into the body tissue being treated. The fluid can be saline or a chemotherapeutic fluid such as liquid or gas containing a cytotoxic agent, for example. The fluid can be administered in a variety of procedures. The fluid can be passed through a distribution port into the body tissue before, during and/or after the RF power is supplied to the electrode surface, for example. Preferably, the fluid is introduced after a barrier capsule has been formed. The devices comprises electrodes having a hollow core and a closed sharpened distal tip. The electrode has a plurality of fluid distribution ports therein for distribution of fluid treatment agents into the tissue.
