ABSTRACT:
A laparoscopic instrument comprises an elongate shaft, an applicator component on the shaft for applying a biologically active composition to a tissue surface inside a patient during a laparoscopic procedure, and a fiber optic laser beam transmission guide extending along the shaft from a proximal end to a distal end of the shaft. A laser source is operatively connected to the fiber optic guide at the proximal end of the shaft for generating a laser beam for transmission through the guide upon application of the biologically active composition to the tissue surface during the laparoscopic procedure. The applicator component includes, at the distal end of the shaft, a roller or a flexible cup-shaped receptacle which stores a predetermined amount of the biologically active composition and which deforms in response to a pressing of the shaft, to deposit the biologically active composition onto the tissue surface.
