EP1691740A1 — Plunger

USPTO Abstract

The object of the invention is a plunger intended for an inserter for an intrauterine device with a T-body, which plunger has a first end and a second end as well as 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 through which plunger an opening (17) has been arranged in its longitudinal direction so that the longitudinal axis of the opening is substantially the same as the longitudinal axis of the plunger. A plunger according to the invention is characterised in that the opening at the first end of the plunger is arranged to expand in a direction perpendicular to the direction of the longitudinal axis to form a tip portion, so that the tip portion has at least one surface (6, 7, 8, 9, 10, 11), which along at least a portion of the length of the tip portion turns at least 35º in relation to a first plane in parallel with the longitudinal axis and at least 35° in relation to a plane at an angle in relation to the longitudinal axis.
