Abstract
At least a portion of a catheter which is intended to be in contact with bodily tissue for more than a nominal period of time is loaded with an anti-inflammatory agent such as dexamethasone sodium phosphate. The direct loading or compounding of the catheter with the agent resists inflammation and encapsulation of the catheter as a result of the tissue's natural foreign-body response. The anti-inflammatory agent can be provided as a coating or bonded on the outside of the catheter or can be integrally compounded into the body of the catheter.
