ABSTRACT:
An infusion catheter system which includes a generally cylindrical housing member having a passageway extending therethrough, a guiding catheter having a proximal end disposed at one end of the cylindrical housing member such that the passageway in the housing member communicates with a passage in the guiding catheter, and an infusion catheter slidably positioned within the passage of the guiding catheter. The catheter system also includes a manifold valve which is coupled to the housing member for applying a first fluid through the housing member to the passage of the guiding catheter, and a second manifold valve which is coupled to the infusion catheter for applying a second fluid through the passage of the infusion catheter. Typically, an anticoagulate fluid is applied through the guiding catheter to prevent blood clotting during an infusion procedure and a blood clot dissolving fluid, such as streptokinase, is applied through the infusion catheter. With this catheter infusion system, the distal end of the infusion catheter may be precisely positioned within an artery so that the clot dissolving fluid may be effectively administered.
