Claim Text:
1. A system for creating a perfusion reservoir in the coronary sinus of a patient, wherein the reservoir is in fluid communication with a vein draining into the coronary sinus, the system comprising: an elongated shaft formed with a lumen, wherein the shaft defines a longitudinal axis and has a proximal end and a distal end; a first cone shaped balloon membrane having a proximal end affixed to an outer surface of the shaft and a distal end affixed to the outer surface of the shaft to establish a first cone shaped balloon with an inflation chamber between the first balloon membrane and the outer surface of the shaft, wherein the first balloon membrane has a first portion extending from the distal end of the balloon membrane to a balloon membrane midsection and a second portion extending from the midsection to the proximal end of the first balloon membrane, and wherein the second portion establishes a cone angle, α, with a first proximally directed portion of the longitudinal axis of the shaft beginning along the longitudinal axis where the proximal end of the first cone shaped balloon membrane is affixed to the outer surface of the shaft, with α≦90 degrees; a second cone shaped balloon membrane having a proximal end affixed to an outer surface of the shaft and a distal end affixed to the outer surface of the shaft to establish a second cone shaped balloon with an inflation chamber between the second balloon membrane and the outer surface of the shaft; a plurality of perfusion ports formed into the shaft between the distal end of the first cone shaped balloon membrane and the proximal end of the second cone shaped balloon membrane; an inflation unit connected in fluid communication with the inflation chambers of the first balloon and the second balloon to inflate and respectively anchor the first and second cone shaped balloons to create a reservoir between the inflated balloons, anchored in the coronary sinus over a vein draining into the coronary sinus; and an infusion unit connected in fluid communication with the plurality of perfusion ports to transfer a liquid from the perfusion ports and into the reservoir, for subsequent perfusion of the liquid from the reservoir into the vein.
