Abstract
A phacoemulsification irrigation sleeve includes an elongated, resilient, tubular body section configured to surround a portion of a shaft of a phacoemulsification needle, the tubular body section having a distal end and a proximal end, and an inner surface and an outer surface. An enlarged section formed on the proximal end of the tubular body portion surrounds a hub of the phacoemulsification needle and connects the irrigation sleeve to a phacoemulsification handpiece. The irrigation sleeve further comprises at least one slitted irrigation port formed adjacent to the distal end of the body section and configured to splay in response to a drop in pressure between the inner surface and the outer surface.
