Abstract
A catheter is disclosed having an outer sheath made of a porous polymer material such as expanded polytetrafluoroethylene (ePTFE). The sheath has a porosity to allow anti-microbial or anti-bacterial medicament or other medicaments or liquids to pass through the sheath. A medicament lumen is provided passing through the elongated tube of the catheter from the catheter's proximal or out of patient end to openings along the catheter tube wall. Medicament is passed from the proximal end of the catheter through the medicament lumen and expelled through the openings into the area between the sheath and the catheter's main tube. There, the medicament or other liquid passes through the sheath into contact with the patient's body lumen. In the preferred embodiment, the catheter is a Foley urinary catheter.
