Read the full statement (142 words)

The LigaSure™ Vessel Sealing System includes a bipolar electrosurgical generator and dedicated bipolar electrosurgical instruments intended for use in general, laparoscopic and gynecologic procedures where ligation of vessels is desired. The system creates a vessel ligation (seal) by the application of bipolar electrosurgical RF energy (coagulation) to vessels interposed between the jaws of the device.

The generator can also be used with standard bipolar devices where bipolar cutting or coagulation is desired.

The indications for use include general, (including uroclogic, thoracic,plastic and reconstructive), laparoscopic and gynecological procedures where ligation of vessels is performed including such procedures as bowel resections, hysterectomies (both vaginal and abdominal), laparoscopic cholesystectomies, laparoscopically assisted vaginal hysterectomies, gall bladder procedures, Nissen fundoplication, adhesiolysis, oophorectomy, etc. The devices can be used on vessels up to 7 mm. and bundles as large as will fit in the jaws of the instruments.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
