Abstract
A shaped flexible infusion sleeve provides for delivery of an infusion fluid to the tip of a vibrating needle used in a phacoemulsification procedure for removing cataracts. The shaped flexible infusion sleeve has a non-circular cross-sectional shape which allows deformation yet prevents collapse of the sleeve onto the vibrating needle so as to avoid undesired heating during surgery. The shaped flexible infusion sleeve has at least two constriction points which add sufficient structural sniffiness to prevent full collapse of the sleeve once inserted into an incision in the eye, while at the same time providing sufficient flexibility to enhance sealing of the incision.
