Claim 6:
7. A fluid delivery system comprising:
a body defining a cavity therein, the cavity having a cylindrical configuration extending along a longitudinal axis with a delivery opening at a proximal end and an open distal end, the cavity defining a seat surface that extends radially inwardly into the cavity adjacent to the delivery opening and a threaded portion adjacent to the open distal end;
a catheter connection assembly disposed within the cavity and configured to couple a catheter to the body, the catheter connection assembly comprising:
a washer configured to abut the seat surface;
a gasket;
an engagement tip disposed on an opposite side of the gasket from the washer; and
a connector having an external thread configured to engage the threaded portion of the cavity;

wherein the washer, gasket, engagement tip, and connector each define a central passage extending therethrough for reception of a catheter; and the catheter connection assembly is configured such that when the connector is threaded into the cavity, the connector causes the engagement tip and washer to compress the gasket therebetween to thereby radially compress the gasket around the catheter to retain the catheter within the cavity; and
wherein compression surfaces of the engagement tip and the washer engage the gasket on opposite sides thereof; and at least one of the compression surfaces of the engagement tip and the washer has a contoured configuration extending away from the gasket along the longitudinal axis to thereby provide deformation space for the gasket as the gasket is compressed.
