Abstract
Devices and methods for preventing reperfusion injuries when an occlusion balloon is deflated. A catheter having an infusion lumen exiting the catheter distal of a stent balloon and/or occlusion balloon allows a therapeutic agent to be introduced to a target location to establish desired temperatures and pressures prior to deflation of the balloon such that negative effects of reperfusion are minimized.
Claims21
A combined stent delivery and occlusion device comprising:
- a proximal manifold including:
- an infusion port;
- and
- a stent balloon inflation port;
- a catheter extending distally from the manifold and defining an infusion lumen in fluid communication with the infusion port, and an inflation lumen in fluid communication with the stent balloon inflation port;
- a therapeutic agent port in fluid communication with a therapeutic agent lumen further defined by the catheter and leading to a distal end of the catheter;
- a stent balloon near the distal end of the catheter and surrounding the catheter, the stent balloon in fluid communication with the inflation lumen;
- and
- a stent surrounding the stent balloon.
