The outer needle has a longitudinal passage, a length, and a hub on the proximal end of the outer needle. The inner needle has a longitudinal passage and a length that is greater than the length of the outer needle. The inner needle is configured to fit within the longitudinal passage of the outer needle. The adaptor is configured to fit within the hub of the outer needle and includes a tapered longitudinal passage that guides a distal end of the inner needle through the adaptor and into the longitudinal passage of the outer needle. |
