Abstract
Catheter devices and methods for intravascular heating and/or cooling of human or veterinary patients. The catheter devices generally comprise catheters having inflow and outflow lumens and at least one curvilinear balloon connected to the inflow and outflow lumens such that heat exchange fluid may be circulated through the balloon(s). The catheter is inserted into the vasculature and heated or cooled fluid is circulated through the balloon(s) to heat or cool blood flowing in heat-exchange proximity to the balloon(s), thereby effecting heating or cooling of all or a portion of the patient's body.
Claims18
A heat exchange catheter for heating or cooling at least a portion of the body of a human or animal patient, said heat exchange catheter comprising:
- a catheter shaft having an inflow lumen and an outflow lumen extending longitudinally therethrough;
- at least one heat exchange balloon element attached to the catheter shaft and fluidly connected to the inflow and outflow lumens such that heat exchange fluid may circulate in the inflow lumen, through the at least one balloon element and out of the outflow lumen;
- the balloon element being insertable into the vasculature of the patent and having a curvilinear configuration when heat exchange fluid is being circulated therethrough.
