First Claim
Patent Images
1. A phacoemulsification sleeve, comprising:
- i) a rigid sleeve having a bore, an outwardly extending ring held within the bore and a flange on an end of said sleeve for preventing the sleeve from being dislodged from a phacoemulsification incision when inserted therein, the rigid sleeve being sized and shaped to fit within a phacoemulsification incision; and
ii) a flexible irrigation bellows connected to the rigid sleeve forming an irrigation fluid path, the irrigation fluid path extending through the sleeve and into the phacoemulsification incision when said sleeve is inserted into a phacoemulsification incision.
