Abstract

An irrigation/aspiration tip having a shaft with a reduced or relatively small diameter with a distal tip having a relatively large diameter. The diameter of the shaft can vary depending upon the incision size preferred by the surgeon, and the diameter of the distal tip will vary depending upon the size of the phacoemulsification tip preferred by the surgeon.

Claims

1. An irrigation/aspiration tip, comprising:

a) a body; and

b) a distal tip having an infusion sleeve coaxially mounted to the body around an aspirating tube, the aspirating tube having a shaft with a distal end;

wherein the shaft has a reduced diameter relative to the distal end.

2. The irrigation/aspiration tip of claim 1 wherein the infusion sleeve comprises a hollow tube with an internal diameter and the shaft has a reduced diameter relative to the internal diameter of the sleeve.

3. The irrigation/aspiration tip of claim 1 wherein the infusion sleeve comprises a hollow tube with an internal diameter and the distal end of the distal tip has a diameter that approximates the internal diameter of the sleeve.
