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 1–6,†
The LigaSure™ Maryland jaw thoracic device includes features such as:
▪ Narrowed jaw specifications fine-tuned for performance on pulmonary vessels
▪ A 30 cm shaft length to provide a reach similar to commonly used VATS tools
And complements thoracic procedures by providing:
▪ One-step vessel sealing 7
▪ Enhanced blunt dissection 8,9,‡
▪ Secure, atraumatic grasping 8,9,§
▪ Cold cutting 7,8

†Compared to the Ethicon ENSEAL™*, Applied Medical Voyant™*, and the original LigaSure™ Maryland jaw device. Tissue sticking to device jaws instances measured over 110 seals per device (ForceTriad™ energy platform). F1930T is only compatible with the Valleylab™ FT10 energy platform.
‡Compared to the original LigaSure™ Maryland jaw device. Eschar buildup assessed using optical imaging analysis after 60 seal and divide cycles.
§Compared to the original LigaSure™ Maryland jaw device. Cleaning effectiveness assessed after each of two cleaning cycles.
Ω19 of 21 thoracic surgeons surveyed after using agreed when compared to their currently preferred method.
††20 of 32 surgeons surveyed after use agreed when compared to their currently preferred method.
‡‡Harmonic™*HD 1000i is indicated for thoracic procedure but is not specifically indicated for pulmonary vasculature. Temperature based on single activation. Harmonic™* HD 1000i was measured while using advanced hemostasis. All seals were performedon systemic vasculature.
