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 a stylet guide 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 stylet 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 transponders and temperature sensors can be attached to the probe end and/or stylet. The stylet guide can define a stylet path from an axial orientation in the catheter through a curved portion to a lateral orientation at the stylet port.

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 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.

One embodiment includes the electrical conductor being enclosed within a non-conductive sleeve which itself is enclosed within a conductive sleeve in a coaxial cable arrangement to form a microwave transmission line terminated by an antenna. Another embodiment includes a resistive element near the distal end of the stylet which couples the center electrode to an outer conductor to generate joulian heat as electromagnetic energy is applied, such as an RF signal.

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 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 has an integrated circuit or semiconductor apparatus at the distal end thereof to generate electromagnetic radiation directly at the point of the desired target tissue. The stylet includes at least one semiconductor or integrated circuit radiation emitter adapted for electromagnetic radiation when electrically energized. An elongated electrical insulator includes proximal and distal ends adapted to be introduced into a body opening, such as the urethra. First and second elongated electrical conductors are electrically isolated by the insulator. The distal ends of the electrical conductors are connected to the semiconductor, so that electrical energy coupled to the proximal ends of the conductors energizes the semiconductor to cause radiation. In a particular embodiment of the invention, the semiconductor radiation emitter(s) is (are) a laser(s). In another embodiment, it is a microwave oscillator or integrated circuit. In yet another embodiment, two types of semiconductor radiator emitters are located distally on the catheter, and each type is connected to one of the electrical conductors. According to one aspect of the invention, a third conductor may be connected in common to both types of semiconductor radiation emitters. The stylet may include an antenna to aid in coupling radiation from a semiconductor radiation emitter to the surrounding tissue. The stylet may also include an axial aperture adapted for use with a guide filament.

摘要： A medical probe device of this invention comprising a catheter having a control end and a probe end. 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 apparatus comprising a catheter having a stylet guide housing with one or more stylet ports therein and stylet guides for directing one or more flexible stylets outward through respective stylet ports and through intervening tissue to target tissue. The active stylets emit radio frequency RF energy which establishes an RF current in the patient. The current, being densest at the stylet tips, causes heating of the surrounding tissue to initiate ablation of the target tissue. One aspect of the invention includes temperature sensing stylets at the location of the RF emitting stylets to monitor the temperature of the tissue being ablated. This allows the surgeon to have increased knowledge about the abating action under way in order to control the intensity of the applied RF current, or to adjust the amount of time the current is applied, or both. Further included herein is a plurality of temperature sensors mounted on an ultrasound probe to be used to monitor tissue temperature at the ultrasound probe while allowing the ultrasound device to monitor the position and orientation of the medical probe apparatus of the present invention.
