1. An access catheter comprising:
- a flexible catheter body having a proximal end and a distal end;
a fitting secured to the distal end of the catheter body;
a rigid access tube having a base adjacent to the fitting and being fluidly connected to the catheter body and extending from the fitting; and
a compressible element secured to the fitting at the base of the rigid access tube and surrounding the base of the rigid access tube and impregnated with an active agent which is expressed from the element as the element is compressed.

Abstract
An access catheter for percutaneously connecting to a subcutaneously implanted port comprises a catheter body having a distal end and a proximal end. A needle or other access tube is connected to the distal end of the catheter body through a fitting, optionally at a right angle relative to the catheter body. A compressible element impregnated with an antiseptic, antibiotic, anesthetic, or other active agent, is provided adjacent the distal end of the catheter body and surrounding the needle. When the needle is percutaneously introduced to the port, the compressible element will be compressed to express the agent onto the skin surface surrounding the penetration site.
