Forward flow impeding infusion sleeve and associated systems and methods

摘要

An infusion sleeve for use in partially covering a phacoemulsification tip during a surgical operation is disclosed herein. The infusion sleeve includes a flexible elongate portion having a lumen extending therethrough with the phacoemulsification tip running through the lumen. The flexible elongate member further includes a lateral port configured on a side of the flexible elongate member, a straight section, and a tapered section. The tapered section is located at a distal portion of the flexible elongate member and has a first wall subsection having a uniform thickness and a second wall subsection having thickness larger than the uniform thickness. The second wall subsection flexes to maintain circumferential contact with the phacoemulsification tip.
