Infusion system with fixed occluding wire

摘要

An improved catheterization system includes (i) an occluding wire; (ii) a catheter, and (iii) a fluid supply port in fluid communication with the catheter. The occluding wire includes (i) an elongate wire body; (ii) an occluding tip coupled to a distal end of the elongate wire body; and (iii) a hub coupled to a proximal end of the elongate wire body. The hub of the occluding wire is configured to be coupled to the catheter. The hub of the occluding wire thus prevents the occluding tip from moving in a longitudinal direction with respect to the catheter once the occluding tip has been placed in a desired position with respect to the catheter.
