Publication number: 20220126014Abstract: A device for wound irrigation and debridement includes a body extending along a longitudinal axis. The body comprises an interior region and an opening such that that the interior region and the first opening are configured to transfer an irrigation fluid. The body comprises a compliant region having a first stiffness and a debridement region having a different second stiffness. The compliant region defines a distal surface. In a first configuration, the compliant region defines a first axial dimension, the distal surface engages a target body region, and the debridement region is axially offset from the distal surface and disengaged from the target body region. In a second configuration, the compliant region is compressed to define a second axial dimension less than the first axial dimension, thereby engaging the debridement region with the target body region, and the distal surface engages the target body region.Type: ApplicationFiled: February 4, 2020Publication date: April 28, 2022Applicant: THE REGENTS OF THE UNIVERSITY OF MICHIGANInventors: Paul Stephen CEDERNA, Nishant GANESH KUMAR, Jeffrey Stephen PLOTT

Publication number: 20220071478Abstract: A method and apparatus for testing the integrity of an anastomosis of a bodily lumen includes a multi-lumen tubular body having a first balloon that can be positioned proximally of an anastomosis, a second balloon that can be positioned distally of the anastomosis, and an aperture on the tubular body intermediate the first and second balloons. Once the first and second balloons are inflated, they define, in concert with the surrounding bodily lumen, a region that can be used to observe integrity of the anastomosis prior to conclusion of surgery. A fluid, such as air, is introduced through the aperture to the testing region, and a camera and lights provided on the instrument facilitate observation of any behavior of the fluid indicative of leaks in the anastomosis.Type: ApplicationFiled: December 20, 2019Publication date: March 10, 2022Inventors: Curtis Bergquist, Jeffrey Stephen Plott, Mark S.
