Ethicon launches Enseal G2 Articulating Tissue Sealer

Device allows surgeons to take a perpendicular approach to vessel sealing

Ethicon Endo-Surgery has launched its Enseal G2 Articulating Tissue Sealer in the US. The company claims that the device is the first and only, articulating advanced energy device designed to allow surgeons to take a perpendicular approach to cut and seal vessels up to 7mm in diameter and lymphatics through a 5mm port.

The Enseal G2 Articulating is unique because it can bend, making it easier for surgeons to access difficult to reach parts of the anatomy and provides better access to tissue in deep or tight spaces for greater control of the angle of approach to vessels, according to the company1.

It allows surgeons to take a perpendicular approach to vessel sealing, which contributes to stronger seals when compared to Enseal non-articulating devices. It also increases their ability to take the full vessel in a single bite, reducing the likelihood of internal bleeding and post-surgery complications for patients.

The “Perpendicular Blood Vessel Sealing in Surgical Practice” White Paper, a cross-specialty collaboration between Drs Andrew I Brill and Michael J Stamos, concludes that in certain procedures, “technical accuracy and the security of vessel sealing are best accomplished using a perpendicular approach for the clarification of key anatomy and the optimal use of advanced bipolar electrosurgery.”2

Vessels sealed with a perpendicular approach using Enseal G2 Articulating are more than 28% stronger than vessels sealed at a 45 degree angle.3

“The Enseal G2 Articulating allowed me to perform the entire para-aortic dissection from the same port,” said Dr Steven A Elg, GYN-Oncologist, Iowa Methodist. “Prior to Enseal articulation this was not possible.”

Enseal G2 Articulating builds on the company’s existing portfolio of advanced bipolar tissue.

The Enseal advanced bipolar devices incorporate an I-Blade that delivers high uniform compression along the entire length of the jaw. The Enseal G2 Tissue Sealer portfolio also includes the Enseal G2 Super Jaw device, launched in 2011, and the Enseal G2 Curved and Straight Tissue Sealers, launched in 2012.

With NSLG2C35A devices, median burst pressures  were 51% higher for vessels sealed at a 90° angle compared to vessels sealed at a 45° angle (p=0.0007). With NSLG2S35A devices, mean burst pressures were 28% higher for vessels sealed at a 90° angle compared to vessels sealed at a 45° angle (p=0.001).
