摘要： An abnormality detection system for highly precise detection of an abnormality in a laser treatment device includes a laser transmission tube coupled with a laser treatment unit, oscillating laser light, a discharge-side water pressure sensor, and a water pressure detection liquid surface level meter detecting a change in a pressure of cooling water flowing through forward-direction and a backward-direction spaces in the laser transmission tube. The laser transmission tube includes a hollow wavelength path having a lightguide space formed in a longitudinal direction, and an outer case enclosing an outer circumferential surface of the hollow waveguide path and extending in the longitudinal direction. The discharge-side water pressure sensor and the water pressure detection liquid surface level meter detect the change in the pressure of the cooling water flowing through in a forward-direction space and a backward-direction space to detect any abnormality.

摘要： Various methods, systems, and devices for treating tissue ablation are disclosed. Some embodiments disclosed herein pertain to methods of treating tumors, systems used for irradiating tissue and tumors with electromagnetic radiation, components and devices of that system, and kits for providing systems used for irradiating tissue and tumors with electromagnetic radiation. In some embodiments, the system provides sub-ablative infrared radiation that is absorbed by nanoparticles. In some embodiments, the nanoparticles absorb the radiation converting it into heat energy. In some embodiments, though the infrared radiation itself may be sub-ablative, the heat energy generated by the nanoparticles is sufficient to cause thermal coagulation, hyperthermia, and/or tissue ablation.

摘要： An irrigated ablation catheter includes a shaft and an electrode assembly affixed to a distal end of the shaft. The distal electrode assembly includes a manifold and an ablation electrode affixed together and extending along a center axis. The electrode has a distal irrigation passageway extending therethrough to an opening at a distal tip of the electrode. The opening of the irrigation passageway is offset in distance from the center axis, and allows a thermal sensor such as a thermocouple to be located in a sensor cavity in the electrode on or near the center axis. One variation involves providing a pair of distal irrigation passageways through the electrode where both of the openings of the passageways are offset from the center axis. The thermal sensor in this variation is located in the sensor cavity substantially on the center axis.

摘要： A medical device includes a body and at least one electrode disposed thereon. The electrode includes a metallic substrate, such as a platinum group metal, an alloy of platinum group metals, or gold. The surface of the substrate is modified in a manner that increases its effective surface area without inducing bulk heating. For example, the surface of the substrate can be laser textured and/or coated, such as with titanium nitride or iridium oxide.

摘要： An aspect of various embodiments of the present invention system and method provide, but not limited thereto, a novel means for epicardial ablation using a double-curve steerable sheath and a double-curve deflectable open irrigated-tip/suction catheter that can be guided around the apex of the heart and adjusted so as to position the distal tip optimally. The catheter can also both deliver fluid to and withdraw fluid from the pericardial space. Access to the epicardial surface of the heart is via a subxiphoid entry. The method and means presented include, but are not limited to, steering, energy delivery, bipolar mapping, placement and use of electrodes, irrigation, suction of irrigation fluid, and other details of the subject invention.

摘要： Systems, assemblies, and methods to treat pulmonary diseases are used to decrease nervous system input to distal regions of the bronchial tree within the lungs. Treatment systems damage nerve tissue to temporarily or permanently decrease nervous system input. The treatment systems are capable of heating nerve tissue, cooling the nerve tissue, delivering a flowable substance that cause trauma to the nerve tissue, puncturing the nerve tissue, tearing the nerve tissue, cutting the nerve tissue, applying pressure to the nerve tissue, applying ultrasound to the nerve tissue, applying ionizing radiation to the nerve tissue, disrupting cell membranes of nerve tissue with electrical energy, or delivering long acting nerve blocking chemicals to the nerve tissue.
