Abstract
The present invention uses several innovative means in order to effectively puncture the intimal wall of blood vessels reliably and controllably. The total penetration of the needle is controlled by the height of the needle projecting from its base and the degree of penetration is controlled by the use of “cam” or similar means or mechanisms that moves the base containing the needles.
