Apparatus and methods for directional delivery of laser energy
WO 2006033989 A3
Abstract
In some embodiments, without limitation, the invention comprises a catheter (10) having an elongated housing (12) with a channel disposed therein. A laser delivery member is movable and at least partially disposed within the channel. A ramp (20) is adapted to move the distal end of the laser delivery member outwardly from the central axis odf the housing. A guidewire biases the distal end of the laser delivery member generally inwardly toward the central axis of the housing. In some embodiments, without limitation, the offset of the central axis of the tip of the laser delivery member from the central axis of the housing is determined by adjusting the the extent to which the laser delivery member travels on the ramp (20), and disposition of the laser delivery member on the guide wire maintains the offset tip substantially apralell to the central axis of the housing., thus, in accordance with the invention, the distal end of the laser delivery member may be biased ina desired direction or offset, permitting ablation of an area larger than an area of the distal end (16) of the catheter (10).
