<p>Hole forming apparatus (100) for forming an opening in a blood vessel (106), comprising: a penetration head (104) for insertion through a wall of a blood vessel (106). The apparatus (100) has a base section (102) and at least one cutting surface (114) on at least one of the base section (102) or the penetration head (104). The cutting surface (114) is adapted to contact first an intima surface of the blood vessel (106). The apparatus (100) further has a shaft operatively connected to the cutting surface (114) and configured to rotate the cutting surface (114) relative to the blood vessel (106), while the penetration head (104) and the base sectiom (102) are brought together,m to effect a removal of a plug tissue section from the blood vessel (106).</p> |
