Patent ID: 7661429

Claim:
A plunger intended for an inserter for an intrauterine device with a T-body, wherein the plunger has a first end and a second end, and a first dimension, which is the longitudinal direction of the plunger, and the length of which plunger in its longitudinal direction is substantially larger than the diameter of the cross-section perpendicular to the longitudinal direction, and the cross-section of which plunger is substantially circular, and the plunger has an opening in its longitudinal direction such that the longitudinal axis of the opening is substantially the same as the longitudinal axis of the plunger, wherein the opening is at the first end of the plunger and expands in a direction perpendicular to the direction of the longitudinal axis to define a tip portion, so that the tip portion has at least one surface, which along at least a portion of the length of the tip portion turns at least 35° in relation to a first plane in parallel with the longitudinal axis, wherein said at least one surface turns also at least 35° in relation to a plane that is perpendicular to said direction of the longitudinal axis, along at least a portion of the length of the tip portion, such that said at least one surface will turn an intrauterine device having a T-body from an incorrect position into a correct position for positioning said intrauterine device within said plunger as the intrauterine device is being retracted into position within said plunger.
