Abstract:
1. A vascular incision apparatus comprising: a body; a puncturing and cutting member having a needle with a sharp point for penetrating a blood vessel and a cutter for making an incision in the blood vessel, which cutter is disposed proximal to the needle; incision length controlling means for controlling the length of the incision made by the puncturing and cutting member; and the incision length controlling means has a stopper arm with a stop thereon that comes into resting contact with the puncturing and cutting member at a boundary between the needle and the cutter or at the needle; wherein said contact by the stop with the puncturing and cutting member controls the length of penetration by the needle into the blood vessel and said stopper arm is provided such as to enable repositioning thereof relative to the puncturing and cutting member between a first position which prevents the cutter from cutting the blood vessel and a second position which allows the cutter to cut the blood vessel.
