1. A surgical device for forming a channel within tissue with laser energy and comprising:
- a housing;
an optical fiber for transmission of said laser energy secured to said housing;
a hollow needle defining an open bore surrounding at least a portion of said optical fiber; and
a switch for activating laser energy transmission operatively associated with said housing and rsponsive to an actuator rod operatively associated with said switch.

Abstract
A surgical device is provided for forming a channel through or into tissue utilizing both mechanical energy and laser energy. The device includes a needle for forming the first part of the channel. The needle has an open bore. Mounted within the bore is an optical fiber for emitting laser energy to form the balance of the channel.

9. A method of operating on heart tissue having an epicardium and an endocardium, said method comprising:
-
penetrating said heart tissue with a needle having a through bore with an optical fiber secured to a housing and received within said bore; urging an actuator rod against said epicardium, said actuator rod being operatively associated with said housing and a switch; moving said actuator rod in an opposite direction relative to said needle such that actuator rod contacts [a] said switch for controlling a shutter; opening said shutter to allow transmission of laser energy through said optical fiber; transmitting said laser energy through said optical fiber; emitting said laser energy from said optical fiber to form a channel; detecting when said optical fiber has penetrated to a desired depth within said heart tissue; closing said shutter to terminate transmission of laser energy through said optical fiber; and withdrawing said needle from said heart tissue. - View Dependent Claims (10, 11, 12, 13, 14, 15)
