Publication number: 20170164998Abstract: A method of ablating a tissue site includes at least two stages. A first stage involves conducting bipolar ablation between a first pair of electrodes situated in an opposing arrangement on opposing sides of the tissue site to form a pair of opposing first stage ablation regions extending from respective sides of the tissue towards the center. A second stage involves conducting bipolar ablation between a second pair of electrodes situated in a diametrical arrangement with respect to the first stage ablation regions, which forms a second stage ablation region intermediate the pair of first stage ablation regions. The second stage completes the ablation through the entire depth of the tissue site. Since the overall process can accommodate incomplete ablation during the first stage, lower power, reduced ablation times or both may be used during the first stage, avoiding overheating and with a decrease in ablated tissue volume.Type: ApplicationFiled: January 4, 2017Publication date: June 15, 2017Inventor: Gleb V.

Publication number: 20150073245Abstract: A contact sensing assembly including a catheter including an electrode having a base portion mounted adjacent a head portion of the catheter body. A sensor is disposed adjacent the base portion for measuring compression or tensile forces applied to an electrode tip portion, and includes a predetermined sensitivity. The base and head portions include predetermined rigidity so that forces applied to the electrode tip portion are determinable as a function of the sensitivity and a sensor output. A contact sensing assembly also includes an electrode pipe operatively connected to the catheter body for movement and bending with the catheter body, and an electrode wire disposed in the electrode pipe and including isolation. A change in capacitance resulting from movement of the electrode wire toward the electrode pipe or contact of the electrode wire with the electrode pipe during bending of the catheter correlates to a force applied to the catheter.Type: ApplicationFiled: September 25, 2014Publication date: March 12, 2015Inventors: Gleb V.

Method and system for using common subchannel to assess the operating characteristics of transducers
Patent number: 8186877Abstract: A system and method for using a common subchannel to assess operating characteristics of one of a plurality of transducers that are coupled to said subchannel is disclosed. The plurality of transducers are divided into subsets and each subset is coupled to a subchannel. The system is configured to activate a selected transducer on the subchannel and the subchannel delivers operational information on the activated transducer. The present invention reduces the number of subchannels required to collect information on the plurality of transducers. The present invention may utilize one or more loading conditions to take at least one measurement, which at least one measurement is then used to derive operational information on the transducer. In one configuration, information on the amount of energy being delivered to the transducer is collected simultaneously with information on the operating temperature. In another embodiment only the temperature is measured.Type: GrantFiled: December 30, 2007Date of Patent: May 29, 2012Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Gleb V.
