The beauty part of CTUM is their is no direct competition, as E.O. Patton has perfected the technology.
There is, however, a firm in Canada, I believe, that has had some success with tissue welding, but has not reported anything even near what LTC has.
Many months back, someone brought it to the CTUM board attention, but after review, we pretty much dismissed it/them as being much less developed.
Someone from the board, here, may remember the company, as I do not.
