OVERVIEW
Reliable vessel-sealing technology
Tailored for Thoracic Surgery
The LigaSure™ Maryland jaw thoracic sealer/divider is part of our commitment to transforming lung care.
It’s the first — and only — minimally invasive LigaSure™ device designed for VATS procedures and indicated for sealing pulmonary veins and arteries up to and including 7 mm.1-5,6
The multifunctional LigaSure™ Maryland jaw thoracic device complements thoracic procedures by providing:
- One-step vessel sealing7
- Enhanced blunt dissection8,9,†
- Secure, atraumatic grasping8,9,†
- Cold cutting independent of sealing7,8
The LigaSure™ Technology Difference
Reliable LigaSure™ vessel-sealing technology drives the LigaSure™ thoracic device. It works by using the body’s own collagen and elastin to create a permanent seal that is designed to withstand three times normal pulmonary systolic blood pressure.3
Plus, LigaSure™ technology eliminates the guesswork — and minimizes thermal spread8,10,‡ — by automatically discontinuing energy delivery when the seal cycle is complete.11
