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.

A grouping of Enseal products.
  1. Compared to previous generations of Enseal devices (099986-210202).
  2. 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).
  3. 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).
  4. 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)
  5. (166204-210202)
  6. Based on metrology data, ENSEAL® X1 Curved Jaw Tissue Sealer has a 16% (or 3.4mm) longer jaw than LigaSure Maryland (LF1937) (p < 0.001) and ENSEAL® X1 Curved Jaw Tissue Sealer has a 9% (or 1.15mm) wider jaw aperture than LigaSure Maryland (LF1937) (p < 0.001). (145041-200629)
  7. Metrology report comparing ENSEAL® X1 Curved Jaw to LigaSure Maryland (LF1937) (p < 0.001) (093769-180619)
  8. (095323-180718)
  9. Grasping force measured as the maximum amount of force required to pull porcine jejunum from the distal tip of device jaws. Comparison of ENSEAL® X1 Curved Jaw to LigaSure Maryland (LF1937) (p < 0.001) (149828-200813)
  10. As compared to devices with less than 360° degree shaft rotation (099992-181108)
  11. Mean thermal spread measured via histology on porcine carotid arteries. Care should be taken near thermally sensitive tissues. See IFU for complete warnings and cautions. (095310-210202)
  12. Comparison of ENSEAL® X1 Curved Jaw to LigaSure Maryland (LF1937). Benchtop testing on porcine arteries (1055mmHg vs. 862mmHg, p < 0.001). (145069-200629)
  13. Enabled by Adaptive Tissue Technology algorithm powered by GEN11. (134168-210203)
