Abstract
An electrosurgical medical device and method for creating thermal welds in engaged tissue that carries the electrosurgical components in a disposable cartridge. The instrument also can carry a blade member in a disposable cartridge, thus making the instrument system inexpensive to use. In another embodiment, the electrical leads of the cartridge have a surface coating of a thermochromic material to provide the physician with a visual indicator of operational parameters when applying energy to tissue.
