Publication number: 20240131355Abstract: A phototherapy device is provided for treating a medical condition by delivering phototherapy using a pad and a light source supported by the pad. The light source includes multiple light emitters that are located at different positions on the pad and that emit treatment electromagnetic radiation. A treatment property of the phototherapy varies spatially based on medical properties of the anatomical treatment area.Type: ApplicationFiled: February 17, 2022Publication date: April 25, 2024Applicant: MUREVA PHOTOTHERAPY INC.Inventors: Vedang KOTHARI, Jordan W. OJA, Jason D. LAZZARA, Samuel J. SHELNUTT, Nancy LIPKO

Publication number: 20240024694Abstract: According to an exemplary embodiment, an intraoral phototherapy device is provided for that improves tissue illumination. Oral tissue illumination is particularly difficult in the oral cavity inside of the teeth. That is, it is particularly difficult to illuminate the roof of the mouth and tissues located towards the back for the throat. The intraoral phototherapy device improves illumination of these tissues using a probe having a cylindrical main body.Type: ApplicationFiled: March 4, 2021Publication date: January 25, 2024Inventors: Vedang Kothari, Jordan W. Oja, Jason D. Lazzara, Samuel J. Shelnutt

Publication number: 20220226667Abstract: An intraoral phototherapy device is provided that improves tissue illumination. Oral tissue illumination is particularly difficult inside of the teeth. That is, it is particularly difficult to illuminate the roof of the mouth, floor of the mouth, sides of the tongue, and/or ventral surface of the tongue. The intraoral phototherapy device improves illumination of these tissues using a bifurcated central projection that receives a portion of the tongue. An intraoral phototherapy device is also provided that includes a breathing tube to improve patient breathing and vocalization for enabling illumination of tissues at the back of the Zo mouth. An intraoral phototherapy device is additionally provided that allows for separate control of light emission from different areas of the intraoral phototherapy device.Type: ApplicationFiled: January 15, 2021Publication date: July 21, 2022Inventors: Vedang Kothari, Jordan W. Oja, Jason D. Lazzara, Samuel J. Shelnutt

Patent number: 10010696Abstract: Various equipment and methods associated with providing a concentrated product gas are provided. In one embodiment, the equipment includes an input device first and second sieve tanks, a variable restrictor, and a controller. In one embodiment, the method includes: a) selecting a desired output setting for the concentrated product gas from a plurality of output settings, b) separating one or more adsorbable components from a pressurized source gaseous mixture via first and second sieve tanks in alternating and opposing pressurization and purging cycles to form the concentrated product gas, and c) selectively controlling a variable restrictor based at least in part on the desired output setting to selectively provide flow between the first and second sieve tanks such that the flow for at least one output setting is different from the flow for at least one other output setting in relation to corresponding pressurization cycles.Type: GrantFiled: June 27, 2016Date of Patent: July 3, 2018Assignee: Invacare CorportionInventors: Thomas B. Sprinkle, William J. Daniels, Thomas A. Drobnak, David G. Felty, Valentine A. Hodos, Martin J. Fabian, Samuel J. Shelnutt, Jonathon R. Olszewski
