Patent ID: 7789846

Claim:
A system for providing selective thermal therapy, the system comprising: a first elongated element with a first wall defining a first lumen having a first lumen distal end and a first lumen proximal end and a length from said proximal end to said distal end, wherein said first lumen is a delivery lumen for delivering thermally treated blood to a target site in the body; an exit port located on said first lumen, said exit port for delivering said thermally treated blood to the target site; an occlusion element positioned on said first lumen, proximal to said exit port; a second elongated element with a second wall, wherein a second lumen is defined as a space between said first wall and said second wall, and said second lumen is coaxial to said first lumen, said second lumen having a second lumen proximal end and a second lumen distal end, wherein said second lumen is a supply lumen for receiving normothermic blood from the body, said second lumen distal end positioned relative to said first lumen distal end such that said second lumen distal end is in such proximity to said first lumen distal end so that said second lumen acts as an insulating layer along a majority of said length of said first lumen when receiving the normothermic blood; 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; an inlet positioned on said second elongated element, said inlet proximal to said occlusion element, said inlet for receiving the normothermic blood; and a control unit in fluid communication with said proximal ends of said first lumen and said second lumen, said control unit comprising: a supply blood inlet in fluid communication with said second lumen, said supply blood inlet for receiving the normothermic blood from the body; a thermal adjustor in fluid communication with said supply blood inlet, said thermal adjustor configured for changing a temperature of the received normothermic blood so as to provide said thermally treated blood; and a delivery blood outlet in fluid communication with said thermal adjustor and in fluid communication with said first lumen, said delivery blood outlet for providing the thermally treated blood to said first lumen.
