Abstract: 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.

Abstract: A catheter system including an infusion catheter interacting with an occluding wire. The infusion catheter has an interior surface defining a lumen longitudinally extending between a proximal end and a distal end. The interior surface of the catheter includes a cylindrical first portion positioned at the proximal end, a cylindrical second portion positioned at the distal end, and an annular, sloped, tapered portion extending therebetween. The second portion terminates at a tip opening. An annular sensing ridge radially inwardly projecting around the tip opening. A plurality of small infusion holes extend through the side of the infusion catheter proximal of the tapered portion. The occluding wire includes a thin placement wire having an enlarged occluding ball placed at the distal end thereof. Projecting from the occluding ball on the side opposite the positioning wire is a coiled spring wire. The spring wire has ridges formed by the top of the wire and grooves formed between each coil.

Abstract: A fluid infusion system includes a pump having a body that slidably interacts with a handle. The body includes a valve housing fluid coupled with an inlet passageway, an outlet passageway, and a dispensing barrel. A finger rest rigidly projects from the dispensing barrel. A loading chamber is recessed within the finger rest and is configured to receive a fluid supply syringe. A plunger, mounted to the handle, is slidably received within the dispensing barrel. As the plunger is advanced within the barrel, fluid is dispensed from the pump. As the plunge is retracted within the barrel, the barrel is automatically filed with a fluid. The nozzle of the pump is fluid coupled to a hemostasis valve which is in turn fluid coupled to an infusion catheter. The infusion catheter has a distal end with an enlarged tip opening and a plurality of small infusion holes extending through the side thereof. An annular sensing ridge radially inwardly projects from the interior of the catheter at the tip opening.
