<p>An apparatus (10) for sealing approximated edges of tissue with thermal energy includes a clamp (16) having members (28, 30) which grasp and hold tissue. A transmissive material (52) is supported by at least one of the members. The members (28, 30) pivot to pull the tissue edges in tight approximation against the transmissive material (52) to form a seam. Thermal energy is then directed at the tissue through the transmissive material (52) and at the seam with sufficient intensity and duration to heat the tissue to an adhesive proteinaceous substance to seal the seam. The approximated seam is held against the transmissive material (52) with an appropriate pressure to avoid over inverted or over everted tissue approximation.</p> |
