Indications for Use
The HydroFlex LI System is designed to provide controlled irrigation during laparoscopic procedures. The system helps flush blood and tissue debris from the operative site during laparoscopy to aid in visualization. It may also be used for dissection of filmy adhesions (i.e. hydrodissection), hydrodissolution of blood clot formations, and peritoneal lavage.
Device Story
HydroFlex LI is an electromechanical laparoscopic irrigation system. It consists of a reusable electronic controller and a disposable pumping chamber/tubing set. The system uses an impeller pump to deliver irrigation fluid to the operative site. The user selects a pressure setting on the controller, which regulates impeller speed to maintain the desired flow. The system automatically resumes flow when back pressure drops below the set threshold. It is used in clinical settings during laparoscopic surgery to improve visualization and assist in dissection or lavage. The device provides controlled fluid delivery, helping surgeons clear the operative field of blood and debris. It is not intended for hysteroscopy or cavity distention.
Clinical Evidence
Bench testing only. Performance was assessed via experimental methods to verify adequate flow rates for laparoscopic procedures. Biocompatibility of materials and electrical safety were verified against established standards.
Technological Characteristics
Electromechanical impeller pump system. Materials include cyrolite and polyvinylchloride. Controller provides pressure-regulated flow up to 500 mmHg (10.0 psig). Connectivity is standalone. Electrical safety complies with UL 2601-1 and ANSI/AAMI ES1-1993.
Indications for Use
Indicated for use during laparoscopic procedures to flush blood and tissue debris, aid visualization, perform hydrodissection of filmy adhesions, hydrodissolution of blood clots, and peritoneal lavage. Contraindicated for hysteroscopy or cavity distention.
