Patent number: 11103306Abstract: Various catheters with expandable and contractible fluid pathways extending therethrough, and methods of use, are provided herein. In an exemplary embodiment, a catheter is provided with an elongate body having an electrode at the distal end thereof. One or more expandable members or wings can extend between the electrode and the distal end of the elongate body. The catheter can also include an actuator extending therethrough and coupled to the electrode such that movement of the actuator is effective to advance and retract the electrode, thereby moving the one or more expandable members between a collapsed configuration and an expanded configuration. The catheter can also include a fluid sealed lumen formed therein and configured to receive fluid and to deliver fluid to one or more pathways formed in the electrode. The actuator can extend through the fluid sealed lumen, however it can be fluidly separated from the lumen.Type: GrantFiled: October 22, 2019Date of Patent: August 31, 2021Assignee: Sirona Medical Technologies, Inc.Inventors: Ali Haghighi-Mood, Richard Jonathan Cohen

Publication number: 20210015549Abstract: Improved ablation procedures and exemplary catheters for use with such procedures are provided. In one example, high quality homogenous lesions with well-defined borders can be created by introducing into a patient body a catheter that includes an electrode that is mounted on a distal end of the catheter, positioning the electrode to be in contact with tissue to be ablated such that at least 65 percent of an exposed distal surface area of the electrode is in contact with the tissue to be ablated, and applying electrical energy to the electrode sufficient to create an ablation lesion in the tissue.Type: ApplicationFiled: May 29, 2020Publication date: January 21, 2021Inventors: Ali Haghighi-Mood, Richard Jonathan Cohen

Patent number: 9560977Abstract: The systems and methods described herein enable reliable estimation of cardiovascular indices on real-time, non-invasive or minimally-invasive, and beat-to-beat basis. Cardiovascular indices which can be estimated include: stroke volume (SV), which being limited to, cardiac output (CO) and total peripheral resistance (TPR). In various embodiments, one or more of these indices are estimated continuously, on a beat-to-beat basis, using peripheral arterial blood pressure (ABP) waveforms and certain parameters derived from the peripheral ABP waveforms. The derived parameters are substantially insensitive to distortions of the ABP waveform arising from tapered arterial branches throughout the arterial tree. The methods describe herein can provide a more accurate and reliable estimate of hemodynamic parameters than existing techniques.Type: GrantFiled: June 26, 2014Date of Patent: February 7, 2017Assignee: Massachusetts Institute of TechnologyInventors: Richard Jonathan Cohen, Kichang Lee, Tatsuya Arai
