IS-001 Injection in Patients Undergoing Robotic-Assisted Gynecological Surgery
July 13, 2023 updated by: Intuitive Surgical
A Phase 3 Multi-Center Efficacy Study of IS-001 Injection in Patients Undergoing Robotic-Assisted Gynecological Surgery Using the da Vinci® Surgical System With Firefly® Fluorescent Imaging
This study evaluates the safety and efficacy of intravenous injection of IS-001 to aid in intraoperative ureter structure delineation.
Study Overview
Detailed Description
Injury to the ureter, the duct by which urine passes from the kidney into the bladder, is a well-known and serious complication of pelvic and abdominal surgery that frequently goes unrecognized intraoperatively.
This study seeks to evaluate the safety and efficacy of intravenous IS-001 injection to improve surgeon ureter visualization during robotic-assisted surgery with the da Vinci® Surgical System and Firefly® imaging.
