Publication number: 20190083173Abstract: 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.Type: ApplicationFiled: September 18, 2018Publication date: March 21, 2019Inventors: Huisun Wang, Christopher J. Geurkink

Publication number: 20190083176Abstract: Aspects of this disclosure pertain to a device with an elongated body having a distal end. The distal end may comprise a port that permits discharge of a laser energy towards a tissue from an optical fiber located in the distal end. An exterior surface of the distal end may include a cauterization portion that permits discharge of a cauterization energy towards the tissue. In some aspects, the device includes an insulative portion that attaches the distal end to the elongated body and limits energy transfer therebetween. Related systems and methods are also disclosed.Type: ApplicationFiled: November 9, 2018Publication date: March 21, 2019Applicant: Boston Scientific Scimed, Inc.Inventors: Hui Wang, Wen-Jui Ray CHIA, Rongwei Jason XUAN, Jian James ZHANG, Aditi RAY, Honggang YU

Publication number: 20190083177Abstract: A distal end of an optical fiber may be protected by a variety of alternative protective caps, tips, and/or sleeves. In one example, a generally cylindrical soft tip is arranged to fit over the end of the fiber, and to compress in an axial direction when pressed against a stone to allow a recessed tip of the fiber to contact the stone or to be maintain a minimum spacing between the fiber tip and the stone and thereby limit erosion of the fiber tip.Type: ApplicationFiled: May 4, 2017Publication date: March 21, 2019Inventor: Joe D.

Publication number: 20190083178Abstract: A C-arm, or a mobile intensifier device, is one example of a medical imaging device that is based on X-ray technology. Because a C-arm device can display high-resolution X-ray images in real time, a physician can monitor progress at any time during an operation, and thus can take appropriate actions based on the displayed images. Monitoring the images, however, is often challenging during certain procedures, for instance during procedures in which attention must be paid to the patient's anatomy as well as a medical imaging device display. In an example, a surgical instrument assembly includes a processor, a surgical instrument configured to operate on an anatomical structure, and a display coupled to the processor and attached to the surgical instrument. The display can be configured to display visual information comprising X-ray images generated by a medical imaging device.Type: ApplicationFiled: September 21, 2017Publication date: March 21, 2019Inventors: Mario MATA, Glen PIERSON, George MIKHAIL, Scott LARSEN

Publication number: 20190083179Abstract: A device and method is provided for a trackable suction tool for surgical use. The tracked suction tool includes a tubular handle with a main tube and an entrance tube extending from the main tube, a flattened section of the main tube with a suction-regulating orifice, a tip connected to the main tube distal end and a tracking mechanism connected to a handle proximal end. A method is provided for tracking the position of a tracked suction device including attaching a tip to a handle in one of a plurality of fixed positions, attaching a tracking mechanism to the handle in one of a plurality of fixed positions, calibrating the position of the tip with a positional tracking system using the tracking mechanism, positioning the tracking markers in view of the positional tracking system and tracking a position of the distal end of the tip of the suction device.Type: ApplicationFiled: September 21, 2017Publication date: March 21, 2019Inventors: Leila Kheradpir, Kyle Richard Dupont, Jakub Jankowski

Publication number: 20190083180Abstract: The present technology relates to a medical image processing apparatus, a medical image processing method, and a program that make it possible to accurately detect a surgical tool. The medical image processing apparatus includes: an imaging unit that images an object on which a luminescent marker is arranged; and a processing unit that processes an image captured by the imaging unit, in which the processing unit extracts a color emitted by the luminescent marker from the image, and detects a region in the image in which the extracted color is distributed as a region in which the object is located. Moreover, the processing unit calculates chromaticity for each of pixels in the image, extracts a pixel having chromaticity corresponding to an emission color of the luminescent marker, and detects the extracted pixel as a region in which the object exists.Type: ApplicationFiled: February 28, 2017Publication date: March 21, 2019Inventor: HIROSHI ICHIKI
