Abstract:
1. A tissue treatment apparatus for restoring patency in a body vessel, the tissue treatment apparatus comprising: an elongated catheter dimensioned for insertion within a body vessel having an at least partial occlusion, the elongated catheter defining a longitudinal axis and having proximal and distal ends; proximal and distal expandable segments mounted to the elongated catheter and being positionable adjacent the occlusion, the proximal and distal expandable segments being adapted to transition from a first contracted condition to a second expanded condition; and a continuous mesh in operative engagement with the proximal and distal expandable segments, the continuous mesh being expandable radially outwardly from the catheter upon corresponding transition of the proximal and distal expandable segments to the second expanded condition, and the continuous mesh comprising a conductive material adapted to transmit electrosurgical energy to the occlusion; wherein a maximum outer diameter of the proximal and distal expandable segments is greater than a maximum outer diameter of the conductive continuous mesh to prevent the conductive continuous mesh from contacting the body vessel.
