This invention is an irrigation sleeve (10) for use with a hand held portion (50) of a phacoemulsification apparatus. The irrigation sleeve includes a base portion (12) configured for removable attachment to the hand held portion (50) of the phacoemulsification apparatus, an extending portion (14) connected to the base portion (12), a passageway (16) extending through the base, and extending portions (12, 14). In a preferred embodiment, the irrigation sleeve (10) is substantially rigid, and at least the extending portion (14) is made from a plastic material selected from the group consisting of polysulfone, polycarbonate, polyimide, and polyetherimide. In another preferred embodiment, the irrigation sleeve (10) is made of silicone, and a substantially rigid wall portion is connected to an inner surface of the irrigation sleeve. |
