An apparatus and method for generation of a protective sleeve against infections for a percutaneous lead through human or animal skin. The percutaneous lead (1) includes an extrusion port (7). When the lead extends through a body (3) of a patient, a pump (9) in operative connection with the lead is operative to move biocompatible liquid polymer material from a reservoir (10) through the extrusion port. As the polymer material comes in contact with body tissues of the patient it forms a protective sleeve against infections (5). The protective sleeve must be periodically clipped as it continuously or intermittently grows in an upward direction (6) outside of the body. The continual formation of the protective sleeve prevents the formation of a biofilm on the percutaneous lead that can cause the body tissue to separate from the percutaneous lead.
