Patent number: 9827405Abstract: An ingestible gastric volume reduction device (100) is provided that is controllably adjustable between an expanded state and a contracted state. A control subsystem within the device is able to selectively transition the device between both states. Such control can be by way of a biological or chemical sensor (102) in the device, a wireless (RF) receiver (104), or timer. Thus activation of the device whether to expand and fill a gastric volume or to contract to open up the gastric volume may be achieved from internal control (within device) or external control (to the device). The device may be used for patient treatment, by administering the device (e.g., through ingestion) to a gastric region and then controllably increasing and/or decreasing the volume of the device during treatment.Type: GrantFiled: May 26, 2011Date of Patent: November 28, 2017Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Elif A.

Patent number: 9757194Abstract: Devices, systems and methods are disclosed for the ablation of tissue. A steerable ablation catheter can include one or more ablation elements at its distal end and one or more ablation elements fixedly attached to its shaft. The distal end of the ablation catheter can be deflected to assume a number of different deflection geometries in at least one direction along the shaft.

Publication number: 20150366461Abstract: An endoscopic system may include an endoscopic device and a control apparatus. The device may include a housing membrane having a distal end and a transparent outer layer around a periphery of the housing membrane and extending longitudinally from the distal end to define a side volume of interest, and an optical infrared sensor array comprising infrared sensors extending longitudinally along and circumferentially about a longitudinal axis of the device to detect infrared radiation over the side volume. The control apparatus may include a processor and a computer-readable medium having computer-executable instructions that cause the processor to, determine temperature data for the side volume in response to infrared data from the infrared sensor array, determine if the temperature data is in a temperature region of concern in a vessel, and provide a temperature control signal to a subsystem to instruct the subsystem to reduce temperature in the vessel.Type: ApplicationFiled: January 26, 2015Publication date: December 24, 2015Inventors: Hakan Oral, Fred Morady

Patent number: 9037223Abstract: An atrial fibrillation classification system collects celectrocardiogram signals and converts them to a frequency, time, or phase domain representation for analysis. An evaluation stage extracts energy density profile over a range of frequencies, time intervals, or phases, which is then summed and normalized to form dispersion metrics. The system then analyzes the dispersion metrics, in their respective domains, to determine whether a patient is experiencing an arrhythmia and then to classify the type of arrhythmia being experienced.Type: GrantFiled: January 10, 2013Date of Patent: May 19, 2015Assignee: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Hakan Oral, Omer Berenfeld, Grant Kruger

Patent number: 8971997Abstract: An infrared fiber-optic device is able to monitor esophageal temperature during an ablation/cryoablation procedure over a volume of interest to sense whether the temperature is too high or too low. The device may include a plurality of optical fibers each with a wide angle lens collectively disposed circumferentially and longitudinally to cover the volume of interest, as the particular region over which undesirable temperature may not be known beforehand. In other examples, the device may include an embedded array of infrared sensors extending sufficiently to encompass a volume of interest. The device may be used as part of a feedback control to regulate and stop operation of the ablation/cryoablation procedure to prevent vessel damage.Type: GrantFiled: March 24, 2009Date of Patent: March 3, 2015Assignee: The Regents of the University of MichiganInventors: Hakan Oral, Fred Morady
