Abstract
A catheter which allows injection into a target region without imposing large burden on a medical patient can be provided. A catheter (1) is used by being inserted from outside of a body into a blood vessel and a distal end thereof being reached inside of a heart, that is a target region, while a proximate end thereof remaining outside of the body. The catheter (1) is configured in a way so that an injection mechanism (5) conducts injection into myocardium from inside of a heart while a forceps mechanism (3) holds myocardium inside of the heart. In the forceps mechanism (3), a grasping portion (13) provided at the distal end of the catheter (1) opens and closes in conjunction with manipulation at a first handling portion (11) provided at the proximate end of the catheter (1). In the injection mechanism (5), an injection needle (43) provided at the distal end of the catheter (1) is protruded from the distal end of the catheter (1) in conjunction with manipulation at a second handling portion (41) provided at the proximate end of the catheter (1).
