Abstract
Systems and methods for continuous infusion of a fluid, which may be heated, into a balloon catheter. A system for balloon inflation, the system comprising a catheter having an inflow lumen and an outflow lumen, a balloon positioned at a distal end of the catheter, the balloon being in fluid communication with the inflow and the outflow lumen, and an infusion device in fluid communication with the balloon through the inflow and outflow lumens, the infusion device configured for continuously circulating a fluid into and out of the balloon to maintain the balloon at a constant pressure and volume by matching a flow of the fluid into the balloon via the inflow lumen with a flow of the fluid out of the balloon via the outflow lumen in order to keep the balloon volume and pressure constant during an entire infusion.
