ABSTRACT:
A catheter assembly for packaging in sterile condition within a protective removable envelope is provided. The catheter assembly includes a shield structure incorporating an elongated hollow body defining a bore therethrough. The body is separable into two halves and each half of the body has a portion of the shield structure supported therefrom. A catheter has its distal end slidingly telescoped into one end of the bore and a tubular lubricant reservoir is provided and includes a first open end and a second collapsible bulbous end. The open end is telescoped over the distal end of the catheter and into the corresponding end of the body bore. The reservoir has a frangible seal within its open end and telescoping engagement of the open end of the reservoir into the body bore functions to clamp the distal end of the catheter against withdrawal from the body bore. The proximal end of the catheter is contained within a sealed and readily openable tubular envelope and the envelope has one end thereof sealingly engaged with the separable portions of the shield. In addition, the envelope, adjacent its end remote from the shield sealingly receives therethrough the discharge neck of a collapsible fluid reservoir.
