Abstract:
1. A reperfusion catheter system, comprising: an introducer sheath having an inner wall defining a longitudinal opening extending from a proximal portion to a distal end; a balloon catheter having an outer wall and having a longitudinal opening extending from a proximal end to a distal end, the balloon catheter disposed through the opening in the introducer sheath, the balloon catheter having an inflatable balloon at the distal end, the balloon catheter configured to allow a catheter to be inserted through the entire opening of the balloon catheter from the proximal end of the balloon catheter to the distal end of the balloon catheter; a conduit having a first end disposed in fluid communication with the inside of the introducer sheath and having a second end disposed in fluid communication with the inside of the balloon catheter; wherein antegrade blood flow is established in a lumen of a target vessel through a path between the inside of the introducer sheath, through the conduit, through the opening in the balloon catheter, and exiting through the distal end of the balloon catheter; wherein the conduit includes a lateral check flow member extending laterally from the introducer sheath, the check flow member having a stopcock at an end of the lateral check flow member opposite the introducer sheath, the conduit further including a single connecting tube having first and second ends and extending between the stopcock and a side port of a valve system, wherein the first end is attached to the stopcock and the second end is attached to the side port of the valve system, wherein the valve system attaches to the proximal end of the balloon catheter; wherein substantially all of the blood flowing through the conduit reaches the longitudinal opening of the balloon catheter and does not branch off into other branches of other conduits.
