Patent number: 11596439Abstract: A surgical access device and methods for facilitating access through an incision or wound to a surgical site in a patient's body comprising an inferior retention member, a superior retention member, and a pliable membrane therebetween. The pliable membrane includes a base layer, a permeable membrane attached to the base layer, and a fluid delivery region disposed between the layers. The fluid delivery region is fluidly coupled to a fluid source. The fluid is delivered to the surgical site via the permeable membrane. The inferior retention member provides for fluid removal from the surgical site. Methods are provided for use of the surgical access device to retract tissue and deliver fluid to the tissue from the pliable membrane.Type: GrantFiled: May 7, 2020Date of Patent: March 7, 2023Assignee: Prescient Surgical, Inc.Inventors: Jonathan Coe, Jeremy Koehler, Nicholas Spinelli, Edward Ruppel, III, Kevin McDermott

Patent number: 10993709Abstract: A surgical access system facilitates access to a surgical site within a patient's body through an incision in the body. Surgical access systems can have at least one retention member and a fluid transportation member configured to deliver fluid to a surgical site or to remove fluid from a surgical site. In some embodiments, a surgical access device irrigates a surgical site to reduce surgical site infections and removes fluid from the surgical site to increase a physician's visibility into the surgical site.Type: GrantFiled: September 4, 2018Date of Patent: May 4, 2021Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Insoo Suh, Jonathan Coe, Swaminadhan Gnanashanmugam, Jeremy Koehler, Mark Welton
