ABSTRACT:
This invention pertains to catheters used with human beings for drainage of any cavity and of a variety of configurations. In particular, the invention is for using a microporous material with interconnected pores of 0.5 to 5 microns diameter such as polyethylene, polypropylene, fluorocarbon or other material that will release a controlled flow or oozing for several days of a liquid from the catheter by differential thermal expansion produced by contact with the patient. The microporous structure of the catheter may be charged with or recharged with liquids such as distilled water, antiseptics, antibiotics, enzymes, etc. which are contained and retained in the interstices so that the catheter may be described as being "self-sterilizing". Also, the catheter has other desirable features including being self-lubricating for ease of insertion and removal, and offering the opportunity for the administration of medication.
