Abstract:
An apparatus for translumenal delivery of energy through a biological lumen having a circumference, comprisinga catheter having a proximal end and a distal end to position within a biological lumen, at least three guide channels forming a plurality of guide channels within the catheter and positioned about the circumference of the catheter, the plurality of guide channels extending from near the proximal end to near the distal end of the catheter, each guide channel including a diverting region near the distal end bending radially, a plurality of energy delivery devices within corresponding guide channels in the plurality of guide channels, the plurality of energy delivery devices having distal ends, wherein the plurity of energy delivery devices within the plurality of guide channels may be positioned in a withdrawn position so that the distal ends of the plurality of energy delivery devices lie within the guide channels, and in an extended position so that the distal ends of the plurality of energy delivery devices are diverted by the diverting regions of the guide channels and extend circumferentially about the circumference of the catheter; and an adaptor, coupled with the plurality of energy delivery devices, to supply energy for transmission through the plurality of energy delivery devices.
