Abstract

A draining catheter for the prevention of infectious diseases around its outside periphery, which has a secondary channel system for the application of anti-microbial agents to the area surrounding its outside periphery.

Claims

1. A catheter comprising:

an elastomeric tubular device for passing into the human body containing

a first channel passing through the entire length of said catheter, open proximate one end to the outside of said catheter for receiving fluid, and a means at the other end to contain or dispose of said fluid, and

one or more secondary channels generally parallel to said first channel with closed ends proximate the open end of said first channel, with slits or punctures through the wall to the periphery of said catheter, said slits or punctures being dimensionless and closed by elastic memory until pressurized from within said secondary channel or channels.

2. A catheter as set forth in claim 1 wherein said secondary channels are combined into one channel proximate the open end.

3. A catheter as set forth in claim 1 wherein said combined channel contains connecting means for connecting to a pressure and pumping source.
