Abstract:
1. A system for providing selective thermal therapy, the system comprising: a first elongated element having a first lumen therethrough, said first elongated element having a distal end and a proximal end and a length from said distal end to said proximal end; an exit port located at said distal end of said first elongated element; an occlusion element positioned on said first elongated element, proximal to said exit port; a second elongated element having a second lumen therethrough, said second elongated element coaxial to said first elongated element, said second elongated element having a proximal end and a distal end, said distal end of said second elongated element proximal to said distal end of said first elongated element, said distal end of said second elongated element positioned relative to said distal end of said first elongated element such that said distal end of said second elongated element is in proximity to said distal end of said first elongated element so that the second lumen acts as an insulating layer along a majority of said length of said first elongated element when receiving blood from the body; wherein said second elongated element is insertable into an artery of the body at a peripheral location of the body and adapted to extend to a remote location of the body; a second port located at said distal end of said second elongated element, said second port proximal to said occlusion element; and a control unit in fluid communication with said first lumen and said second lumen, said control unit comprising:
