Abstract: A percutaneous access device is provided including a sleeve having an inner lumen extending therethrough that is adapted to slidably receive a catheter, and at least one flange disposed around the sleeve and adapted to be positioned adjacent a tissue surface. In a preferred embodiment, the device includes a first flange disposed around the sleeve and adapted to be positioned adjacent a first tissue surface, and a second flange disposed around the sleeve and spaced apart from the first flange such that the second flange is adapted to be disposed adjacent a second tissue surface opposed to the first tissue surface. In use, the flanges 16, 18 are positioned on opposed sides of tissue so that the device 10 is effective to prevent tissue surrounding the percutaneous access device from coming into contact with the catheter as it is introduced through the sleeve 12. The device also includes an antimicrobial agent that is effective to protect against bacterial colonization on and around the access device, the catheter, and the tissue surface surrounding the access device.

Abstract: 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.
