Abstract

Abstract An infusion sleeve for an ultrasonic tissue removal surgical tool includes a sleeve designed to surround the ultrasonically driven tip of the surgical tool and create an irrigation fluid channel thereinbetween. The sleeve includes a flexible portion which permits retraction of the distal end thereof to permit contact between the tip of the surgical tool and body tissue to be destroyed or removed. The infusion sleeve also includes a rigid portion which is designed to prevent collapse of the sleeve around the ultrasonically driven surgical tip and prevent blockage of irrigating fluid flow and subsequent overheating of the tip and damage to adjacent body tissue.
