Patent ID: 8911464

Claim:
A puncture apparatus comprising: a freely rotatable puncture member possessing a distal end portion and a proximal end portion, the puncture member including a bent region at which the puncture member is bent, the distal end portion of the puncture member including a puncture needle for puncturing living body tissue as the puncture member is rotated about a rotation center to rotate a needle tip of the puncture needle toward the living body tissue to puncture the living body tissue; an elongated urethral-insertion member configured to be inserted into a urethra so that a near-side of the urethral-insertion member is the side of the urethral-insertion member located closer to the rotation center, and the far-side of the urethral-insertion member is the side of the urethral-insertion member located farther from the rotation center; and restriction means for restricting a positional relationship between the puncture member and the urethral-insertion member so that the needle tip of the puncture needle which is rotating about the rotation center after first puncturing the living body tissue passes on the far-side of the urethral-insertion member.
