Abstract:

A catheter assembly for conveying fluid from a fluid source to an anatomical site. A connector portion couples the catheter assembly to the fluid source. The catheter assembly comprises an elongated tube having an open proximal end engaging the connector portion and a closed distal end for inserting into the anatomical site. The elongated tube defines a central lumen and a plurality of apertures in an infusion section thereof to convey the fluid from the central lumen to the anatomical site. An air elimination device is coupled to the elongated tube between the connector portion and the infusion section. Seals are placed between the air elimination device and the elongated tube to prevent air from entering the central lumen of the elongated tube distally of the air elimination device and blocking fluid flow through the plurality of apertures into the anatomical site.
