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

Patent number: 9833623Abstract: A method is described for decreasing activity of at least one sympathetic nerve, nerve fiber or neuron innervating at least one blood vessel in the pulmonary vasculature of a patient to ameliorate pulmonary hypertension. In one embodiment, the method may involve advancing an intravascular treatment device to a target location in a target blood vessel within the pulmonary vasculature of the patient and using the treatment device to decrease activity of at least one sympathetic nerve, nerve fiber or neuron innervating the target blood vessel at or near the target location to ameliorate pulmonary hypertension.Type: GrantFiled: April 13, 2015Date of Patent: December 5, 2017Assignee: THE BOARD OF TRUSTEES OF THE LELAND STANFORD JUNIOR UNIVERSITYInventors: Swaminadhan Gnanashanmugam, Jonathan A.

Patent number: 9788823Abstract: Several methods to reduce surgical site infections include inserting a surgical access device into an incision, retracting tissue, and introducing fluid into the surgical access device such that the fluid exits the surgical access device and irrigates a surgical site. Other methods do not include introducing fluid into a surgical access device but include suctioning a fluid into the surgical access device and removing the fluid from the body.Type: GrantFiled: June 15, 2015Date of Patent: October 17, 2017Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Insoo Suh, Jonathan Coe, Swaminadhan Gnanashanmugam, Jeremy Koehler, Mark Welton
