摘要： The invention relates to an injection device containing a hollow needle (1), a cutting needle that can be inserted into the hollow needle and that has a cutting tip projecting from the front end of the hollow needle, a catheter (9) that replaces said cutting needle and that can be inserted approximately up to its front end into the hollow needle (9), said catheter having a receiving chamber (30) for a substance in the form of a capsule on its distal end, in addition to a mandrin (29) that can be inserted into the catheter (9) and which can be placed in a position defining a receiving chamber (30) filled with capsules (22) on the distal end of said catheter, wherein the capsules (22) contained in the receiving chamber (30) of the inserted catheter (9) are released without exerting any pressure in the target area of the body (23) once the injection device has been arranged in a target area of a body (23) by relatively pulling back both the catheter (9) and the hollow needle (1) in relation to the mandrin (29) and by then withdrawing the mandrin (29). Preferably, the catheter (9) contains a removable sieve (28) on its frond end.
