ABSTRACT:
A catheter or balloon catheter includes a tube or balloon which is provided with a plurality of pores. A stimulus-responsive polymer is attached to the pores so that fluid transmission through the pores is controllable by a stimulus such as a change of pH, composition, and temperature. The catheter can administer a necessary limited amount of medicament to a locally limited site of a blood vessel only when necessary.
