FROCKED MEDICAL INSTRUMENT TO BE PLACED IN THE BODY, METHOD OF PRODUCING THE MEDICAL INSTRUMENT TO BE PLACED IN THE BODY AND APPARATUS FOR PRODUCING THE MEDICAL INSTRUMENT TO BE PLACED IN THE BODY

摘要

The present invention provides a percutaneous terminal having a substrate thereof flocked with fibers having bio-affinity, and thereby being able to adhere tightly to a living body, a medical instrument to be placed in the body, and a production method and a production apparatus of the percutaneous terminal and the medical instrument to be placed in the body. The percutaneous terminal according to the present invention is one which the surface of the substrate is flocked with bio-affinitive short fibers (e.g. hydroxyapatite complex particles), therefore the bio-affinitive short fibers are risen perpendicular to or substantially perpendicular to the surface of the substrate. As a result, an area of the bio-affinitive short fibers 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 biological tissues is improved. Thus, it is possible to stably fix to the living body a medical device such as a catheter or the like which has the percutaneous terminal. The medical instrument according to the present invention is also flocked with the short fibers as described above, therefore it is possible to stably fix to the living body the medical instrument to be placed in the body.
