Patent number: 11298568Abstract: Systems and methods for ablating tissue include an ablation device having an energy source and a sensor. The energy source provides a beam of energy directable to target tissue, and the sensor senses energy reflected back from the target tissue. The sensor collects various information from the target tissue in order to facilitate adjustment of ablation operating parameters, such as changing power or position of the energy beam. Gap distance between the energy source and target tissue, energy beam incident angle, tissue motion, tissue type, lesion depth, etc. are examples of some of the information that may be collected during the ablation process and used to help control ablation of the tissue.Type: GrantFiled: October 23, 2017Date of Patent: April 12, 2022Assignee: Auris Health, Inc.Inventors: Hira V. Thapliyal, David A. Gallup, James W. Arenson

Patent number: 11207549Abstract: An ablation system for treating atrial fibrillation in a patient comprises an elongate shaft having proximal and distal ends, a lumen therebetween and a housing adjacent the distal end of the elongate shaft. An energy source is coupled to the housing and is adapted to deliver energy to a target tissue so as to create a zone of ablation in the target tissue that blocks abnormal electrical activity thereby reducing or eliminating the atrial fibrillation in the patient. A sensor is adjacent the energy source and adapted to detect relative position of the energy source to the target tissue or characteristics of the target tissue. The system also has a reflecting element operably coupled with the energy source and adapted to redirect energy emitted from the energy source in a desired direction or pattern.Type: GrantFiled: June 13, 2019Date of Patent: December 28, 2021Assignee: Auris Health, Inc.Inventors: Hira V.

Publication number: 20190060677Abstract: Echo-anatomically mapping tissue includes advancing a catheter having an ultrasound transducer toward tissue. A console adjacent the proximal end of the catheter controls catheter movement, and the ultrasound transducer senses tissue. First and second regions of the tissue are ultrasonically sensed while moving the ultrasound transducer along first, and second sensing patterns, respectively. A first 3-dimensional surface map of the first region, and a second 3-dimensional surface map of the second region are generated. The 3-dimensional surface maps are combined to form a combined surface map. Anatomical features may be identified in the first or second sensed regions. The tissue may be ultrasonically ablated while moving the ultrasound transducer along a first ablation path. The first ablation path may form a lesion around the identified anatomical features, and may be selected from a catalog of ablation paths or it may be prescribed by a physician.Type: ApplicationFiled: October 25, 2018Publication date: February 28, 2019Inventors: Hira V.

Patent number: 10154831Abstract: A method for creating a transmural lesion in tissue includes positioning a distal portion of a catheter near the tissue, where an ultrasound transducer is attached to the distal portion and is operatively coupled to a console and processor. The tissue is imaged by energizing the ultrasound transducer at a first power level to produce an ultrasound beam, where the imaging determines a thickness of the tissue, and a gap distance between the ultrasound transducer and the tissue. The tissue is ablated by energizing the ultrasound transducer at a second power level to produce the ultrasound beam. Energy delivered to the tissue during the ablating is controlled, using the processor, where the processor adjusts a speed of the ultrasound beam moving across the tissue based on the thickness and gap distance, to create the transmural lesion.Type: GrantFiled: August 4, 2017Date of Patent: December 18, 2018Assignee: VytronUS, Inc.Inventors: Hira V.

Patent number: 9907983Abstract: A tissue ablation method for treating atrial fibrillation in a patient comprises locating an ostium of a pulmonary vein and positioning an interventional catheter adjacent the ostium. The interventional catheter has an energy source. Collateral tissue adjacent the ostium is located and tissue around the ostium is ablated with energy from the energy source so as to form a contiguous lesion circumscribing the ostium. The lesion blocks aberrant electrical pathways in the tissue so as to reduce or eliminate the atrial fibrillation. The ablating is modified so as to avoid ablating or otherwise damaging the collateral tissue.Type: GrantFiled: September 28, 2012Date of Patent: March 6, 2018Assignee: VytronUS, Inc.Inventors: Hira V.

Publication number: 20170354397Abstract: A transducer subassembly with combined imaging and therapeutic capabilities is disclosed. The subassembly includes heat sinks that are configured to maintain the transducer at a low operating temperature so that the transducer operates at high efficiency and also can handle a wider range of frequencies. The subassembly is also configured to allow cooling fluid to flow past the transducer element. One heat sink in the subassembly also acts as an acoustic matching layer and another heat sink acts as a backing Alternatively, the second heat sink which acts as a backing is optional. The transducer is configured to transmit at one power level for imaging, and at a second power level for ablating. The transducer may comprise sub-elements transmitting at different power levels. The subassembly may be operated at one power level for imaging and a second power level for ablating.Type: ApplicationFiled: August 4, 2017Publication date: December 14, 2017Applicant: VytronUS, Inc.Inventors: Hira V.
