Abstract
An aspiration apparatus includes a barrel having a needle receiving end and a piston receiving end. The barrel has an inner diameter and an outer diameter. The piston receiving end of the barrel has substantially the same inner diameter as the inner diameter of the barrel. The barrel has an opening therein through a sidewall of the barrel. The opening is between the needle receiving end and the piston receiving end. The opening is distant from the needle receiving end. The aspiration apparatus also includes a needle sealingly attached to the needle receiving end of the barrel, and a piston having an end which substantially seals to the inner diameter of the barrel. The piston is capable of a number of positions including a first position near the needle receiving end, a third position past the opening in the barrel.
