This medical device (10) is used when placing a belt-shaped, flexible implant indwelling in the body. This medical device (10) is provided with an elongate puncture needle (31) which, by piercing the body, forms a primary insertion hole (501) through which the implant can be inserted into the body, and a sheath (7) into and out of which the puncture needle (31) can be inserted and removed and which, by passing through the primary insertion hole (501) in an assembled state with the puncture needle (31) inserted, makes said primary insertion hole (501) into a secondary insertion hole. The puncture needle (31) has a puncture needle-side expanding part which, when forming the primary insertion hole (501), expands the primary insertion hole (501) to the same degree as the width of the implant. |
