The probe end includes a stylet guide housing having at least one stylet port and stylet guide means for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. A stylet is positioned in at least one of said stylet guide means, the stylet comprising a non-conductive sleeve having a RF electrode lumen and an optional a fluid supply lumen and a temperature sensor lumen therein. At least one portion of an opposed surface of the electrode lumen and the electrode can be spaced apart to define a liquid supply passageway for delivery of medicament liquid. The RF electrode enclosed within the non-conductive sleeve has a distal length optionally having at least one current focusing groove means thereon and a distal tip shaped to focus current crowding on its terminal end, whereby Rf current passing therefrom into surrounding tissue forms a lesion extending outward from the groove and tip. The focusing groove means can be a plurality of annular focusing grooves or a spiral focusing groove thereon.

摘要： A medical probe device for treatment of the prostate of a human male having a bladder with a base with a urethra formed by a urethral wall extending into the base of the bladder with the prostate having tissue surrounding the urethra near the base of the bladder with a catheter having a control end and a probe end and a passageway extending from the control end to the probe end along a longitudinal axis. A flexible stylet assembly is slidably mounted in the passageway in the catheter and has a distal extremity. The stylet assembly includes a conductive electrode and a sleeve of insulating material surrounding the conductive electrode and permitting a predetermined portion of the conductive electrode to be exposed. A control device is secured to the stylet assembly and to the control end of the catheter for causing movement of the distal extremity of the stylet assembly between a retracted position disposed within the passageway and an extended position disposed outwardly from the probe end whereby the stylet assembly can extend through the urethral wall into the tissue of the prostate with the conductive electrode being disposed in the tissue of the prostate and the sleeve being disposed in the urethral wall. A radio frequency generator is coupled to the conductive electrode for supplying radio frequency energy to the conductive electrode for causing ablation of tissue in the prostate while the urethral wall is protected from the radio frequency energy supplied to the electrode.

摘要： A medical probe apparatus comprising a catheter having a stylet guide housing with at least one stylet port in a side thereof and a stylet guide for directing a flexible stylet outward through at least one stylet port and through intervening tissue to targeted tissues. The stylet guide has a biopsy sample device or other tissue manifesting device at the distal end thereof to gather tissue or perform other operations at the point of the desired tissue such as emitting electromagnetic energy as ablative power to target tissues;.One embodiment of the biopsy sample stylet includes a hollow core sampler including a biopsy needle apparatus for gathering sample tissue. The hollow core sampler has a sharpened end for facilitating the penetration into and gathering of the sample tissue. A second embodiment of the biopsy sample stylet includes a harpoon-like sample stylet when the sharp tip thereof allows for easy entry into the target tissue. The sharpened barbed side opening allows for certain desired tissue to be sampled to be drawn into the side opening for individual cell gathering or complete sample excise or gathering of the desired tissue. The third embodiment is a clam shell or alligator type biopsy jaw device whereby the sharpened biopsy tip thereof allows a tissue sample to be clipped or cut upon activation of the stylet jaws. Still another embodiment comprises a biopsy knife device in conjunction with an electromagnetic emitter for selective tissue sampling or electromagnetic heat ablation, or both, of selected tissue.

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.

摘要： A medical probe device comprises a catheter having a stylet guide housing with one or more stylet ports in a side wall thereof and guide means for directing a flexible stylet outward through the stylet port and through intervening tissue at a preselected, adjustable angle to a target tissue. The total catheter assembly includes a stylet guide lumen communicating with the stylet port and a stylet positioned in said stylet guide lumen for longitudinal movement from the port through intervening tissue to a target tissue. The style can be an electrical conductor enclosed within a non-conductive layer, the electrical conductor being a radiofrequency electrode. Preferably, the non-conductive layer is a sleeve which is axially moveable on the electrical conductor to expose a selected portion of the electrical conductor surface in the target tissue. The stylet can also be a microwave antenna. The stylet can also be a hollow tube for delivering treatment fluid to the target tissue. It can also include a fiber optic cable for laser treatment. The catheter can include one or more inflatable balloons located adjacent to the stylet port for anchoring the catheter or dilation. Ultrasound transducers and temperature sensors can be attached to the probe end and/or stylet.

摘要： Catheter having a high torque capability adapted to be inserted into and through a lumen of a blood vessel comprising a flexible elongate tubular shaft having proximal and distal extremities. The shaft is comprised of a torque tube extending substantially the entire length of the shaft. The torque tube has a cylindrical wall with at least one flexible portion therein with the flexible portion being characterized in that at least one slot is provided in the cylindrical wall subtending an angle of less than 360.degree.. A flexible sleeve encloses the torque tube and serves to cover the flexible portion while permitting the torque tube to bend in the vicinity of the slot a predetermined amount which is less than that which would create a permanent strain in the torque tube.

摘要： An inhalation device having an elongate housing having a passageway for the movement of air therethrough. The passageway terminates in an emptying chamber adjacent that end of the housing which is adapted for insertion into the mouth or nasal passages of a user thereof. The housing has means for receiving and opening a container holding a unit dose of powdered medicament for administration. The opening means includes first means for placing the interior of the opened capsule in communication with the atomosphere and second means for placing the interior of the opened capsule in communication with the emptying chamber via the passageway in the housing. During inhalation, air drawn through the first means causes the powdered medicament to be expelled from the container through the second means, the passageway and the emptying chamber into the nose, throat or lungs of the user where beneficial or therapeutic action of the medicament occurs.

摘要： The present invention comprises a small, precise measuring pump provided with a germ barrier that is specifically designed for intravenous feeding devices in which the fluid being pumped is positively displaced; in which there is no rubbing contact of one member with another which would be destructive of blood being pumped; the pumping chambers are small, so that they will hold as little fluid as possible; and in which the valves are actuated by gravity and which are tight-sealing when the pump is in a substantially vertical position, but which, when the pump is tipped on its side, are open to permit the preliminary filling of the pump with the fluid to be pumped.
