It is intended to provide a percutaneous terminal which has a substrate having been surface-flocked with a biocompatible fiber and shows a high adhesiveness to the living body, a medical instrument to be placed in the body and a method and an apparatus for producing the same. The percutaneous terminal, the surface of the substrate of which has been flocked with a short fiber having biocompatibility (for example, hydroxyapatite complex particles, etc.), has biocompatible short fiber filaments standing up perpendicularly or almost perpendicularly to the surface of the substrate.
As a result, the ratio of the surface area of the biocompatible short fiber filaments coating a unit area of the substrate of the percutaneous terminal to the unit area of the percutaneous terminal substrate is considerably elevated and, in its turn, the adhesiveness of the percutaneous terminal to a biological tissue is improved. Consequently, it becomes possible to stably fix a medical device (for example, a catheter) provided with the percutaneous terminal to the living body. The above-described medical instrument to be placed in the body is also flocked with the short fiber filaments as described above. Therefore, it can be stably fixed to the living body.
