Abstract
A surgical device is provided for forming a channel through or partially through vascular tissue, including vascular tissue, utilizing both mechanical and laser energy, and, if desired, depositing a therapeutic agent therein. The device includes an optical fiber for transmission of laser energy, a housing, and a hollow guide attached to the housing through which the optical fiber extends. A needle is attached to the distal end of the optical fiber in fluid communication with a catheter surrounding the optical fiber. Additionally, an actuator is included operably connected to the optical fiber for selectively extending the needle and/or fiber from the hollow guide. Finally, a laser control device is contemplated operably connected to the optical fiber, transmitting laser energy from the distal end of the fiber after the needle has penetrated a layer of selected distance into the tissue.
