Abstract
A device for use in laser surgical procedures for moving axially an optical fiber element that is connected at its proximal end to a source of laser energy. The distal end of the fiber elements with a cooperating piercing tip member has a tapered configuration so that it is capable of penetrating soft tissue of membrane such as the myocardium or epicardium of a human heart during the revascularization procedure. Various combinations of bundled optical fiber elements are disclosed which provide different tapered distal end designs that can be used in various surgical procedures.
