Abstract
Abstract A closure device for a puncture in a blood vessel is formed of a needle holder having a pair of first needle passages at a front side, and a needle catcher located at the front side of the needle holder to be movable thereto and having a pair of second needle passages aligned with the first needle passages. A pair of needle pushers is slidably located in the first needle passages, and a needle handle is attached to the needle pushers. A pair of needles joined with a suture is disposed in the first needle passages at a side close to the needle catcher. When the needle handle is actuated, the needles in the first needle passages are pushed by the needle pushers and transferred to the second needle passages. Thus, when wall portions are held between the needle holder and the needle catcher, the wall portions are sutured by the needles with the suture.
