1. A method for removing tissue from a body, said method comprising the steps of:
providing a device comprising:
a hollow cannula having at least one opening in the distal end and means for connecting the cannula to a negative pressure source at the proximal end;
a handle, operatively connected to the cannula, for use by a surgeon to direct and control the distal end of the device in a surgical site and advance the cannula into and withdraw the cannula from the surgical site with the required control and force;
a laser fiber having a light output operably positioned proximate the opening for transferring energy to tissue drawn into the cannula through the at least one opening; and
means, operatively connected to the cannula, for delivering irrigation fluid to the vicinity of the laser fiber light output and the opening;
inserting the device through relatively small skin incisions to gain access to the tissue to be removed;
maneuvering the device into and out of the tissue in order to traverse a large area of the tissue in successive passes of the device in and out along the long axis of the device;
simultaneous with the maneuvering motion by the surgeon, applying suction through a suction channel formed in the cannula;
applying energy to the laser fiber during the advancement and withdrawal of the cannula; and
irrigating to provide cooling for the laser fiber and the opening and to reduce buildup of debris around the laser fiber and within the cannula.
