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.

The present invention generally relates to a fluid delivery system for delivering fluid to an anatomical site. More specifically, the present invention relates to a catheter assembly of the fluid delivery system utilizing a plurality of apertures for delivering the fluid to the anatomical site.
A typical fluid delivery system comprises a fluid source to hold fluid such as medication. A fluid conduit conveys the fluid from the fluid source to a catheter assembly. The catheter assembly conveys the fluid to an anatomical site of a patient. A connector couples the catheter assembly and fluid conduit.
A typical catheter assembly comprises an elongated tube defining a central lumen and a plurality of apertures at an infusion section of the elongated tube to convey the fluid from the fluid source to the anatomical site. The apertures provide a corridor for the fluid to enter the anatomical site.
Advantages of the present invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
FIG. 1 is an elevational view of one embodiment of the fluid delivery system of the present invention;
FIG. 1A is an elevational view of another embodiment of the fluid delivery system;
Referring to the Figures, wherein like numerals indicate like or corresponding parts throughout the several views, a fluid delivery system for delivering fluid to an anatomical site 10 of a patient 11 is generally shown at 12. It is to be appreciated that the fluid can be medication, irrigation fluid such as a saline solution, and the like. The fluid delivery system could be used to supply the fluid to the anatomical site 10, to irrigate the anatomical site 10, or other related functions.
Referring to FIGS. 1 and 1A, the fluid delivery system 12 includes a fluid source 14 to supply the fluid to be delivered to the anatomical site 10. The fluid source 14 can include any mechanism or manner to store and/or deliver the fluid to the anatomical site 10 of the patient. Such mechanisms may include, but are not limited to, pain medication pumps, intravenous bags, syringes to inject fluid, and the like. FIG. 1 illustrates the use of an intravenous bag as the fluid source 14 and FIG. 1A illustrates the use of a pain medication pump as the fluid source 14.
A fluid conduit 18 is in fluid communication with the fluid source 14 and conveys the fluid from the fluid source 14 to a catheter assembly 20. The fluid conduit 18 includes a proximal end 29 coupled to the fluid source 14 and a distal end 30 coupled to the catheter assembly 20. For purposes of this embodiment, the fluid conduit 18 is generally illustrated as one possible configuration of a tube set 15 for the fluid delivery system 12. Those skilled in the art will appreciate that any tube set, i.e., a series of tubes and connectors, may be used to couple the fluid source 14 to the catheter assembly 20. For instance, the fluid conduit 18 may include multiple tubes, a stopcock to control a flow rate of the fluid, a converter adapted to couple different diameter tubes, and the like.
