LigaSure

Pronunciation: /ˈlaɪɡəˌʃʊər/

A bipolar electrosurgical device that seals blood vessels up to 7mm in diameter using controlled thermal energy and pressure.

Full Definition

LigaSure is an advanced bipolar electrosurgical system that combines controlled thermal energy with mechanical pressure to create reliable vessel sealing. The device uses proprietary technology to monitor tissue impedance and automatically adjust energy delivery, creating permanent vessel fusion for structures up to 7mm in diameter. This technology significantly reduces operative time and blood loss compared to traditional clipping and suturing techniques in laparoscopic surgery.

Usage

Usage note: Proprietary device name, often used generically for vessel sealing systems.
