secure sealing
ENSEAL® X1 Curved Jaw was designed to create strong and secure seals with reduced tissue trauma, from the first activation to the last.4 11
“If you look at the sealing capacity of the ENSEAL® device, we are very happy with that. It produced bloodless seals.”
Dr. James van Bastelaar
Surgical Oncologist, NetherlandsBased on the experience of Dr. Bastelaar, individual experiences may vary.
Stronger sealing than LigaSure™ Maryland
22% higher burst pressure than vessels sealed with LigaSure™ Maryland.12


Minimal tissue trauma
ENSEAL® X1 Tissue Sealers continuously sense changes in tissue and respond with the optimized amount of energy to seal securely while minimizing thermal damage to surrounding tissue.4 11 13

The power behind a secure seal
Powered by the Ethicon GEN11 Generator, Adaptive Tissue Technology continuously delivers energy intelligently and efficiently in ENSEAL® X1 Tissue Sealer devices to help drive the best possible patient outcomes.13

- ENSEAL® X1 Curved Jaw Tissue Sealer can capture, seal and transect a longer length of tissue per single activation due to a 16% (or 3.4mm) longer jaw (p < 0.001) and a 19% (or 3.5mm) longer cut length (p < 0.001) compared to LigaSure™ Maryland (LF1937). (145163-200630).
- In benchtop testing on porcine arteries, vessels sealed with ENSEAL® X1 Curved Jaw had a 22% higher average burst pressure than vessels sealed with LigaSure™ Maryland (LF1937), (1055mmHg vs. 862mmHg, p < 0.001). (145079-200629).
- 112 of 112 vessels sealed successfully on first pass in an acute porcine model. All seals maintained hemostasis during blood pressure challenge. During blood pressure challenge, systolic blood pressure was increased to at least 200 mmHg for a minimum of 10 minutes to simulate a hypertensive crisis. (095317-200519)
