Abstract:
1. An energy-based instrument for sealing vascular tissue, comprising: a first deforming member and a second deforming member configured to move relative to one another about a pivot from a first position wherein the first deforming member and second deforming member are disposed in spaced relation relative to one another to a second position wherein the first deforming member and the second deforming member cooperate to deform vascular tissue; and an optical system configured to illuminate a portion of vascular tissue with light to seal vascular tissue, the optical system comprising: wherein the light distribution element is disposed in only the first deforming member, and wherein the second deforming member includes the optical reflective material, which is configured to reflect light that has passed through vascular tissue, so that the light passes through vascular tissue a second time.
