摘要： An electrosurgical instrument in which an amplifier for getting microwave power is located in the same region at a radiating structure for delivering that power in a distal portion of the instrument. The instrument may be insertable through the instrument channel of a surgical scoping device, e.g. endoscope. The entire microwave generating line up may be incorporated into the instrument so that only DC input power is needed. The microwave power losses and associated drawbacks present in known devices can therefore be avoided. The amplifier may be fabricated using wide band-gap conductor materials, such as GaN and GaN-based alloys, which offer the ability to fabricate devices that are active at RF and microwave frequencies.

摘要： A surgical snare comprising a means of delivering thermal plasma on to biological tissue encircled by the snare. The snare may be “cold” snare, i.e. formed from insulating material, or active, i.e. connected to receive RF and/or microwave energy to be radiated into the area encircled by the snare. The surgical snare may thus deliver into biological tissue encircled by a retractable loop any one of (i) a plasma to perform surface coagulation, (ii) a non-ionising microwave field (in the absence of plasma) to perform coagulation at a deeper level, and (iii) an RF field to assist with cutting.

摘要： A biopsy forceps tool (preferably for endoscopic use) in which microwave energy is used to coagulate bleeding after a biological tissue sample is collected between a pair of jaws. The pair of jaws define an enclosure that is isolated from the microwave energy itself and insulated from any thermal changes that occur due to application of the microwave energy. The tool comprises a pair of jaws connected to a coaxial cable, each of the pair of jaws comprising an electrically conductive shell, the jaw assembly being movable between a closed position in which the electrically conductive shells enclose an internal volume for holding a tissue sample and an open position in which the internal volume is exposed in order to receive the tissue sample. The electrically conductive shells form a Faraday cage around the internal volume when in the closed position.

摘要： Ablation catheters and systems include multiple inline chambers for containing and heating an ablative agent. The heating chamber includes one or more channels to increase the contact surface area of the ablative agent with the walls of the heating chamber to provide more efficient heating. Induction heating is used to heat a chamber and vaporize a fluid within by wrapping a coil about a ferromagnetic chamber and providing an alternating current to the coil. A magnetic field is created in the area surrounding the chamber which induces electric current flow in the chamber, heating the chamber and vaporizing the fluid inside. Positioning elements help maintain the device in the proper position with respect to the target tissue and also prevent the passage of ablative agent to normal tissues.

摘要： Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment.

摘要： A microwave ablation system is presented including a microwave applicator having an antenna configured to deliver microwave energy and a microwave generator coupled to the microwave applicator and configured to generate a microwave signal and transmit the microwave signal to the antenna. The microwave ablation system further includes a radiometer configured to measure emissions from a thermal field created when the microwave applicator delivers microwave energy, the thermal field providing in-situ quantitative information of a material in the thermal field. The quantitative information is used to automatically adjust power transmission and time settings of the microwave generator to compensate for different thermal environments.

摘要： A method and systems for treating chronic total occlusions, particularly those that are difficult to treat, is disclosed. In this approach, recanalizing the CTO is achieved using a combined antegrade and retrograde approach. The proximal end of the occlusion is penetrated using an antegrade wire, using a traditional approach. Using collateral vessels, the distal end of the occlusion is crossed in a retrograde fashion. By appropriately maneuvering each member and applying radiofrequency energy between the proximal and distal ends of the occlusion, a continuous channel is created.

摘要： A surgical instrument includes a handle, and an elongated shaft extending from the handle. An end effector extending from the elongated shaft is in communication with a source of electrosurgical energy and defines an end effector axis. A roll joint couples the end effector to the elongated shaft and includes a first tubular structure extending distally from the elongated shaft and a second tubular structure rotatably coupled to the first tubular structure. The second tubular structure supports the end effector such that the end effector is rotatable about the end effector axis. A cable wrap volume may be disposed within one of the first and second tubular structures, and a conductor for supplying the end effector with electrosurgical energy is coiled about the end effector axis within the cable wrap volume such that rotation of the end effector about the end effector axis in a first direction unwinds the conductor.
