Abstract
A phacoemulsification needle (100, 100A, 100B, 100C, 100D, 200, 200A) is provided for emulsifying body tissue. The needle (100, 100A, 100B, 100C, 100D, 200, 200A) is adapted to be attached to a phacoemulsification handpiece that imparts a vibration to the needle (100, 100A, 100B, 100C, 100D, 200, 200A). The needle (100, 100A, 100B, 100C, 100D, 200, 200A) has a body (104, 220, 220A) with a distal end (99), a proximal end (106), and an aspiration passage (124) extending between the proximal and distal ends (99, 106). The aspiration passage (124) defines a longitudinally-extending central body axis (110, 110A, 110B, 110C, 110D). The aspiration passage (124) is enlarged at the distal end (99) to define a tip (102, 102A, 102B, 102C, 102D, 210, 210A).
