Publication number: 20230350064Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for using a surfel map to predict reflections in an environment. One of the methods includes receiving a surfel map comprising a plurality of surfels, wherein each surfel corresponds to a respective different location in an environment. Sensor data for one or more locations in the environment is obtained. The sensor data has been captured by one or more sensors of a vehicle. A range map that represents a projection of the surfel map is generated. Range data in the sensor data is compared to the range map to identify one or more locations in the range map that do not match the range data in the sensor data. The one or more locations in the range map that do not match the range data in the sensor data is classified as reflections.Type: ApplicationFiled: April 27, 2022Publication date: November 2, 2023Inventors: Xiaoxiang Hu, Clayton Kunz, David Gallup, Grigory Dzhavadyan

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.

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.

Patent number: 10681336Abstract: Aspects of the disclosure relate generally to generating depth data from a video. As an example, one or more computing devices may receive an initialization request for a still image capture mode. After receiving the request to initialize the still image capture mode, the one or more computing devices may automatically begin to capture a video including a plurality of image frames. The one or more computing devices track features between a first image frame of the video and each of the other image frames of the video. Points corresponding to the tracked features may be generated by the one or more computing devices using a set of assumptions. The assumptions may include a first assumption that there is no rotation and a second assumption that there is no translation. The one or more computing devices then generate a depth map based at least in part on the points.Type: GrantFiled: May 15, 2014Date of Patent: June 9, 2020Assignee: Google LLCInventors: David Gallup, Fu Yu, Steven Maxwell Seitz

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.
