Abstract: A catheter for drainage of or infusion into a body cavity. The catheter comprises an elongated tubular shaft having a distal end provided with at least one port near the distal end and intended to be located in the body cavity. The catheter has an open proximal end for connection to a drain, suction conduit or infusion line. A sleeve is mounted about the shaft extending along a portion at least of the internal body surface contacting part thereof between its proximal and distal ends. The sleeve forms a substantially concentric fluid reservoir between the drainage tube and the sleeve. Filling means are provided at the proximal end of the shaft for supplying to the reservoir a fluid antimicrobial agent capable of controlled passage through the sleeve by diffusion. The inner surface of the sleeve is provided with a plurality of longitudinally extending capillary channels or grooves providing uniform distribution of the fluid antimicrobial agent within the reservoir and throughout the length of the reservoir.

Abstract: A process of making a hollow article from polymeric material is taught. The article is molded in two parts. The two parts are caused to remain in their respective exterior molds. If the hollow article is to be filled with a desired material, a measured amount of filler material is added to one of the formed parts. The exterior molds are brought into opposed position and sealing relationship. The space between the exterior molds is purged with a purging gas and subjected to a partial vacuum. The exterior molds are then closed and subjected to a clamping pressure to join the part halves together and remove flash from the joint. Portions at least of the exterior molds are heated and then cooled. The exterior molds are then opened, and the finished filled article is removed therefrom.
