Abstract:
A phacoemulsifcation needle has a central aspiration passageway extending through a needle body. A hollow shell is attached to and covers at least a portion of the needle body, creating an annular space between the inner surface of the shell and the outer surface of the needle body. At least one port is formed through the needle body communicating between the aspiration passageway and the annular space to create a flow path. The openings to the needle body and the shell may be coplanar or may lie in different planes.
