Method and apparatus for contemporaneous formation of a body structure opening and homologous pedicle

摘要

The present invention provides a surgical needle apparatus having a piercing tip at a distal portion of a needle member. A first edge obliquely extends from the piercing tip to a heel portion of the needle member to define a partial boundary of a bore in fluid communication with a lumen of the needle member. A pair of cutting edges extend longitudinally from the first edge and extend radially outwardly above on outer surface of the needle member. The surgical needle apparatus is configured to create a body structure access site and an adjacent homologous pedicle for post-procedure sealing of the access site.
