Abstract
An optical fiber device for forming channels within a wall of a patient's heart, and particularly the epicardium, which has an elongated optical fiber, a probe tip secured to the distal end of the optical fiber and an outer support tube secured to the proximal portion of the probe tip and a distal portion of the optical fiber proximal to the probe tip. In another embodiment the optical fiber device has an elongated optical fiber, a probe tip secured to the distal end of the optical fiber and a radiating step or projection on the exterior of the probe tip to act as a stopping surface to control the depth of penetration of the probe tip into tissue.
