IMPROVED CATHETER HUB ASSEMBLY Inventors: Leonard F. Czuba Dean G. Laurin ABSTRACT OF THE DISCLOSURE A catheter is provided with an improved hub assembly. The catheter defines an end which, in turn, defines a rela- tively enlarged transverse dimension for the catheter wall and a thickened annular lip, when compared with an adjacent portion of the catheter. A catheter hub defines a bore portion, the bore portion in turn defining a relatively constricted portion and a relatively enlarged portion. The enlarged catheter end is positioned within the relatively enlarged portion of the bore, while the adjacent portion of the catheter is positioned within the relatively constricted portion of the hub. A rigid tubular funnel fits within the bore of the catheter. As a result of this the collapse and subsequent passage of the en- larged catheter end through the relatively constricted portion of the hub is prevented.
