Publication number: 20170181653Abstract: A catheter is provided with improved position and/or location sensing with the use of single axis sensors that are mounted directly along a length or portion of the catheter whose position/location is of interest. The magnetic based, single axis sensors are provided on a single axis sensor (SAS) assembly, which can be linear or nonlinear as needed. A catheter of the present invention thus includes a catheter body and a distal member of a particular 2D or 3D configuration that is provided by a support member on which at least one, if not at least three single axis sensors, are mounted serially along a length of the support member. In one embodiment, the magnetic-based sensor assembly including at least one coil member that is wrapped on the support member, wherein the coil member is connected via a joint region to a respective cable member adapted to transmit a signal providing location information from the coil member to a mapping and localization system.Type: ApplicationFiled: December 23, 2015Publication date: June 29, 2017Inventors: Debby E.

Patent number: 9474850Abstract: Medical apparatus includes a flexible insertion shaft, which is adapted for insertion into a body of a patient. A resilient end section is fixed to the distal end of the insertion shaft and is formed so as to assume, when unconstrained, an arcuate shape. One or more electrodes are disposed at respective locations along the end section. A first lumen runs from the insertion shaft through the end section so as to convey an irrigation fluid to exit the end section through perforations of the electrodes. A second lumen runs through the insertion shaft to a distal opening and is configured to permit a guide wire to pass through the second lumen from the proximal end of the insertion shaft to exit distally through the distal opening, while conveying the irrigation fluid from the proximal end through the distal opening together with the guide wire.Type: GrantFiled: December 11, 2012Date of Patent: October 25, 2016Assignee: BIOSENSE WEBSTER (ISRAEL) LTD.Inventors: Assaf Govari, Ariel Garcia

Publication number: 20160302859Abstract: A system for measuring real-time tissue reflection spectral characteristics during ablation includes a catheter for collecting light reflected from tissue undergoing ablation, a detection component for separating constituent wavelengths of the collected light, a quantification apparatus for generating measured light intensity data of the collected light, and a processor for analyzing the data in relation to time. A method for monitoring formation of steam pop during ablation includes delivering light to tissue, delivering ablative energy to the tissue, measuring the reflectance spectral intensity of the tissue, and observing whether the measured reflectance spectral instensity (MRSI) initially increases in a specified time period followed by a decrease at a specified rate. If the MRSI does not decrease, delivery of ablation energy continues.Type: ApplicationFiled: June 27, 2016Publication date: October 20, 2016Inventors: Chad Allen Lieber, Ariel Garcia, Shiva Sharareh
