Abstract

This paper considers some issues pertinent to laser welding of elastin-based biomaterials to tissues using a pulsed diode laser (10-μs pulse) and indocyanine green (ICG) as an absorbing chromophore to localize laser heating to the 'weld surface', the elastin/tissue interface where welding occurs. Experiments involved laser welding of elastin heterographs to the intimal surface of the carotid artery (in vitro, porcine) as a ≈4×5 mm2spot weld, then determining the breaking strength when the two tissues were pulled in a direction parallel to the plane of the spot weld while submerged in water.
