CATHETER

摘要

A catheter (10) to be attached to an internal organ of a mammal including a human being.  The catheter (10) is provided with a tube (2) which guides a medication from a medication supply source into the body and a sheet section (1) which is provided at the tip of the tube (2) and the rear surface of which at least partially adheres to the surface of the internal organ.  The sheet section (1) comprises apertures (12) communicating with the internal path of the tube (2), and the total area of the apertures (12) is set to be larger than the cross section area of the internal path.  As the result of this, the medication can simply and reliably be administered to a predetermined area in the vicinity of the surface of the internal organ.
