CAPSULARHEXIS DEVICE WITH FLEXIBLE HEATING ELEMENT HAVING AN ANGLED TRANSITIONAL NECK

摘要

Various embodiments of a capsularhexis device include a resistive-heating element comprising an electrically resistive, superelastic wire forming a loop between first and second ends of the superelastic wire. The loop may be retracted into a collapsed, retracted position or ejected into an expanded position. The first and second ends of the loop may at least partially extend at an angle from a planar face defined by the loop, to the insulating portion, to form a transitional neck between the loop and the insulating portion. The transitional neck may have a gap between the first and second ends at the insulating portion that is wider than a gap between the first and second ends on the opposing side of the transitional neck. The gap in the loop of superelastic wire may be sufficiently small to allow the loop to form a continuous cut in a capsule of an eye.
