Embodiment Construction

[0221] Specific embodiments of the present invention relate to a blood vessel closing device and method for closing an opening in tissue, such as a blood vessel closing device including a tissue retraction unit and an opening closing component.

[0222] Organizational retraction:

[0223] In one aspect of the present invention, a retracting unit is provided to retract two opposite parts of the tissue opening. After two arms, sides, etc. are deployed at opposite sides of the opening for closing, the distance between the arms, sides, etc. increases to retract the opposite sides, thereby changing the shape of the tissue opening (opening) A slit is formed in which the two long straight sides of the opening approach in preparation for closure.

[0224] Those skilled in the art will understand that the blood vessel closure described herein follows the principles of surgical blood vessel closure techniques to prevent narrowing or stenosis of the blood vessel to be treated. The retraction ...
