Patent number: 11992431Abstract: An inserter for an intrauterine system can include a handle having an opening, a slider arranged in the opening, a plunger attached to the handle, an insertion tube attached to the slider and arranged around the plunger, and a lock adapted to reversibly lock at least one removal string of the intrauterine system. The lock can include a main part with an opening, the main part being rotatably mounted on a shaft or axle, an extension of the main part, and a counterpart. The removal string passes through the opening of the main part and is immobilized between the main part and the counterpart when the lock is in a locking position. The slider is configured to press against the extension of the main part and turn the main part around the shaft or axle to release the removal string as the slider is moved backwards.Type: GrantFiled: April 23, 2021Date of Patent: May 28, 2024Assignee: Bayer OyInventors: Ilkka Jutila, Heikki Lyytikäinen, Ulla Calvo Alonso, Taina Tjäder, Marjo Ali-Äijälä
