Publication number: 20230248390Abstract: In some embodiments an apparatus for providing access for a medical procedure in a patient's body cavity includes a stem configured for insertion through an opening in a body cavity wall. The stem has a bore and a cap is disposed at a proximal end thereof and includes an entry port in communication with the bore which receives an instrument to be inserted into the body cavity. An inflatable annular seal is disposed on the stem proximate the cap and a conduit extends through the cap providing pressurized gas at a first outlet in fluid communication with the body cavity providing insufflation pressure. A second outlet of the conduit is in fluid communication the seal, which when disposed inside the body cavity proximate the wall and inflated by pressurized gas, bears on an inner surface of the wall urging the cap into contact with an outer surface of the wall while sealing the opening.Type: ApplicationFiled: January 4, 2023Publication date: August 10, 2023Inventors: Evan Rittenhouse Jones, Maxime Blain, Christopher Dean Smith

Patent number: 11586106Abstract: In some embodiments, a stereoscopic imaging apparatus includes a tubular housing having a bore extending longitudinally through the housing. First and second image sensors are disposed proximate a distal end of the bore, each including a light sensitive elements on a face and mounted facing laterally outward. The apparatus further includes a first beam steering element associated with the first image sensor and a second beam steering element associated with the second image sensor. The beam steering elements receive light from first and second perspective viewpoints and direct the received light onto the faces of the image sensors forming first and second images. Either the first and second beam steering elements or the first and second image sensors are moveable to cause a change a spacing between or an orientation of the perspective viewpoints to cause sufficient disparity between the first and second images to provide image data including three-dimensional information.Type: GrantFiled: December 28, 2018Date of Patent: February 21, 2023Assignee: TITAN MEDICAL INC.Inventors: Evan Rittenhouse Jones, Maxime Blain, Christopher Dean Smith

Patent number: 11432960Abstract: An ophthalmic surgical instrument for severing a lens of an eye has an elongated shaft and a snare formed by a wire extending along the elongated shaft and having a looped segment that moves between contracted and dilated configurations. When the shaft is inserted through the pupil and the looped segment is placed around the lens, the bottom portion of the looped segment engages and severs a bottom portion of the lens upon moving toward the contracted configuration. A light-conducting element extends along at least a portion of a length of the looped segment, and a light source is in communication with the light-conducting element, such that light from the light source travels through the element and illuminates at least a portion of the length of the looped segment. The light-conducting element can be a tube surrounding the wire, or can be a solid filament extending adjacent the wire.Type: GrantFiled: February 1, 2022Date of Patent: September 6, 2022Assignee: Accuvision Designs, LLCInventors: Richard James Mackool, Christopher Dean Smith, Evan Rittenhouse Jones, Richard Jonathan Mackool
