    摘要: A device and system for delivery of a flowable biocompatible material to a tissue tract in a controlled manner generally includes a reservoir adapted to be in fluid connection with a cannula, a discharging mechanism adapted to discharge the contents of the reservoir and a cannula retractor to withdraw the cannula. The cannula retractor is operably interconnected with the discharging mechanism so that a measured quantity of the reservoir contents is smoothly discharged to substantially fill at least a portion of the tissue tract.

    摘要: A liquid coolant supply system for supplying a liquid coolant to a thermal therapy catheter includes a sensor control unit, a liquid coolant containment unit and mounts. The sensor control unit includes a pump, a cooling device, a temperature sensor and a pressure sensor. The liquid coolant containment unit includes a sealed reservoir, a coolant-sensor interface module and a pump interface fluidly coupled to the thermal therapy catheter. The coolant-sensor interface module includes a body defining a fluid chamber, a temperature interface supported adjacent the fluid chamber within the body, and a pressure interface supported adjacent the fluid chamber within the body. The mounts removably support the sealed reservoir, pump interface, temperature interface and pressure interface of the containment unit adjacent the cooling device, the pump, the temperature sensor and the pressure sensor. The temperature interface communicates a temperature indicant of the liquid coolant circulating through the fluid chamber to the temperature sensor. The pressure interface communicates a pressure indicant of the liquid coolant circulating through the fluid chamber to the pressure sensor. The cooling device and the pump are controlled based upon the sensed temperature and pressure of the liquid coolant.

    摘要: An intraurethral, Foley-type catheter shaft contains a microwave antenna capable of generating a cylindrically symmetrical thermal pattern, within which temperatures are capable of exceeding 45.degree. C. The antenna, which is positioned within the shaft, is surrounded by means within the shaft for absorbing thermal energy conducted by the tissue and asymmetrically absorbing electromagnetic energy emitted by the antenna--a greater amount of electromagnetic energy being absorbed on one side of the shaft. This asymmetrical absorption alters the thermal pattern generated by the microwave antenna, making it cylindrically asymmetrical, which effectively focuses microwave thermal therapy toward undesirous benign tumorous tissue growth of a prostate anterior and lateral to the urethra, and away from healthy tissue posterior to the urethra.

    摘要: An apparatus is disclosed for advancing an optical fiber in a laser enhanced transluminal angioplasty catheter, and for controlling the introduction of laser energy into the fiber. The device includes a catheter and a fiber advance housing. The optical fiber runs through the catheter and housing, and is optically connected to a source of laser energy. A fiber advance assembly, mounted in the housing, reciprocates to advance and retract the fiber relative to the catheter and housing. An actuator member is provided inside the housing to slide independently of the fiber advance assembly. A switching means, provided in the housing, is closed to enable introduction of laser energy into the optical fiber whenever the fiber advance assembly is disposed forwardly of a select position relative to the actuator member. The switching means is open, thereby preventing introduction of laser energy into the fiber, whenever the fiber advance assembly is disposed rearwardly of the select position. The actuator position is adjustable through a zero adjust slide, connected to the actuator and slidable relative to the housing.

    摘要: A manifold connector, sheath connector and housing connector are provided for independently connecting a fiber enclosing sheath and (laser enhanced) fiber optic catheter housing to a transluminal balloon catheter manifold. The housing connector includes a locking plate enclosure, and a planar locking plate contained in the enclosure to reciprocate between open and locking positions, and spring biased into the locking position. The sheath connector includes an elongate cylindrical body attached to the distal end of the sheath, a disc extended radially outward of the body, and a sleeve extended forwardly of the disc perimeter and coaxial with the body. Two elongate levers also are mounted to the disc perimeter, and normally are aligned with the sleeve. A detent extends radially inward from the distal end of each lever. The manifold connector has an annular groove formed in its exterior, which is positionable to receive a locking blade portion of the locking plate, thus to form an interlocking engagement of the housing connector and manifold connector. An annular recess, formed in the manifold connector behind the annular groove, receives and retains the detents when the sheath connector and manifold connector are engaged.
