  • Patent number: 9737323
    Abstract: 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.

  • Publication number: 20170056057
    Abstract: A method of mapping tissue includes sensing a first region and a second region of a chamber of body tissue. The sensing includes moving an ultrasound transducer of a catheter over a surface of the region along a sensing pattern, and using the ultrasound transducer to gather a set of echo-anatomical data in an amplitude mode at a plurality of points along the sensing pattern. The set of echo-anatomical data comprises distances between the ultrasound transducer and the surface at the plurality of points. A three-dimensional surface map is generated using the set of echo-anatomical data from each region. The surface maps of the regions are combined to form a combined surface map. Methods also include using a set of echo-anatomical data to generate a three-dimensional surface map of a region, from a detected border of the body tissue and detected motion phases of the region.

  • Publication number: 20170056691
    Abstract: 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.

  • Publication number: 20160353089
    Abstract: Systems and methods are described for defining a set of images based on captured images, receiving a viewing direction associated with a user of a virtual reality (VR) head mounted display, receiving an indication of a change in the viewing direction. The methods further include configuring, a re-projection of a portion of the set of images, the re-projection based at least in part on the changed viewing direction and a field of view associated with the captured images, and converting the portion from a spherical perspective projection into a planar perspective projection, rendering by the computing device and for display in the VR head mounted display, an updated view based on the re-projection, the updated view configured to correct distortion and provide stereo parallax in the portion, and providing, to the head mounted display, the updated view including a stereo panoramic scene corresponding to the changed viewing direction.

  • Publication number: 20160346030
    Abstract: Methods and apparatus for treating a patient include an ablation device for ablating a target tissue of a patient. The device includes a housing having proximal and distal ends, and an energy source adjacent the distal end of the housing. The energy source comprises an active portion and an inactive portion surrounded by and extending continuously within the active portion. The active portion comprises a first solid material and is configured to emit ablation energy towards the target tissue when the energy source is energized to create a partial or complete zone of ablation in the target tissue. The inactive portion comprises a second solid material different from the first solid material and does not actively emit energy when the energy source is energized.

  • Publication number: 20160074679
    Abstract: 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.

  • Publication number: 20160038772
    Abstract: Methods for ablating tissue in a patient having atrial fibrillation comprise advancing an elongate flexible shaft through a patient's vasculature into a chamber of a heart. The elongate flexible shaft has an energy source and a sensor. Tissue in the heart is scanned with the sensor and data about the tissue is captured. The captured data is grouped into one of a plurality of tissue classifications and an anatomical map of the tissue showing the grouped data is displayed. At least a portion of the tissue is ablated so as to form a conduction block that blocks aberrant electrical pathways in the heart. The ablated tissue is grouped into one or more predefined tissue classifications during or prior to the ablation.

  • Patent number: 9254011
    Abstract: A lighted belt keeper may include a housing comprising a power source compartment that opens to a first end, wherein a power source may be enclosed by a power source compartment closure. A cover may enclose the power source and power source compartment closure. The cover may removably attach to the first end of the housing. A light may attach to a second end of the housing. The housing and cover may attach to a base which may attach to a first end of a strap by a fastener. A second and a third fastener may be attached to the strap to removably hold the strap in position while the strap may surround an object such as a utility belt, pant belt or the like. In certain embodiments, instead of a strap, the base may have wings that removably attach to each other.

  • Publication number: 20160000502
    Abstract: Methods and apparatus for an ablation device used in the treatment of atrial fibrillation comprise an elongate shaft and a positioning mechanism adjacent the distal end of the shaft. The positioning mechanism is adapted to facilitate location of an anatomic structure and also to anchor the elongate shaft adjacent the anatomic structure. The positioning mechanism comprises an electrode for stimulating the anatomic structure as well as sensing electrical signals. Also, an energy delivery element is adjacent the distal end of the shaft and is adapted to stimulate the anatomic structure and create a zone of ablation that blocks abnormal electrical activity thereby reducing or eliminating atrial fibrillation in the patient.

  • Publication number: 20150109416
    Abstract: 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.
