Abstract
An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

30. A device for cutting a lens within a capsular bag of an eye, comprising:
-
a shaft comprising at least one lumen and a distal portion; a cutting element capable of being configured into a first, retracted configuration with at least a portion of said cutting element being positioned within the at least one lumen, wherein the first, retracted configuration of the cutting element and the distal portion of the shaft are both sized for insertion into an anterior chamber of the eye through an incision, wherein, after insertion of the cutting element into the anterior chamber, a first leg of the cutting element is configured to advance distally relative to a distal end of the shaft and a second leg of the cutting element is configured to move proximally relative to the distal end of the shaft to expand the cutting element from the first, retracted configuration toward a second, expanded configuration having an open area, and wherein the second, expanded configuration of the cutting element is sized and shaped to permit advancement of the cutting element between the capsular bag and an anterior surface of the lens and further advancement of the cutting element between the capsular bag and a posterior surface of the lens to capture a portion of the lens within the open area; and an actuator operatively coupled to the cutting element, for tensioning the cutting element to reduce the size of the open area and cut the lens. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
