Patent ID: 8894664

Claim:
An intraocular lens delivery system cartridge, comprising: a body, and a tubular nozzle connected to the body and projecting distally from the body, the nozzle having a cross-section, the cross-section having a shape defined by: a portion of an ellipse disposed in a first quadrant and a second quadrant of a Cartesian coordinate system, the ellipse having a center that is offset from the origin of the Cartesian coordinate system in a direction along a negative portion of an ordinate axis of the Cartesian coordinate system, the portion of the ellipse defined as a first curve; and a second curve defined as a mirror image of the first curve mirrored about an abscissa axis of the Cartesian coordinate system, the first curve and the second curve forming first and second points at locations where the first curve and the second curve intersect the abscissa axis of the Cartesian coordinate system; and circular arcs formed at opposing ends of the cross-section proximate the first and second points, each circular arc defined as a portion of a circle joining the first curve and the second curve that is tangent to both the first curve and the second curve and that has a 90 degree tangent line at a point along the abscissa axis crossed by the circular arc.
