Re: "The LTC material states a vessel sealing length of 8mm..."

This is apparently a conservative value used by LTC. Elsewhere, in a PR, CSMG describes a 14 mm clinical result:

"We used the automatic control procedure in more than 120 bursts strength tests of vessels between 3.5 to 14 mm in diameter and averaged 1,030 mm Hg burst strength. The significance of the automatic controlled system is we are able to achieve the same burst strength on 14 mm diameter vessels as we were on 3.5 mm diameter vessels. To our knowledge it has been problematic for our competitors to achieve consistently reliable burst strength on vessels over 9-10 mm in diameter."

Re: "The LTC material states a vessel sealing length of 8mm. I am not sure what LTC's limitation for vessel is greater than 8mm? Does anyone know what LTC's limit is in this regard?"
