A flexible medical device which is intended to be disposed in the opening or the incision in the skin tissue of an animal includes a thin, flexible, adherent film coating of a bioactive ceramic material at least at a point where the flexible portion of the medical device exits from the tissue. This bioactive coating bonds with the skin at the exit site to prevent infection of the tissue while allowing the catheter to remain flexible.

Medical device with infection preventing feature

Biocompatible material is deposited onto a substrate by laser deposition, for example by pulsed laser beam deposition and ion-assisted pulsed laser beam deposition. The deposition can be done at room temperature, in a variety of different atmospheres, with control over the stoichiometry, adhesion and porosity of the deposited film. Apparatus for carrying out the deposition, and articles formed by such deposition, are also described. The articles so formed are particularly useful as medical prosthesis, for example, implants.
