An insertion device for an IUD. The insertion device comprises an introducer having an elongate hollow body and a first end and a second end, the hollow body defining an elongate passageway extending from the first end to the second end and defining openings at the first end and the second end, and a pusher provided or configured to be provided inside the elongate passageway such that the pusher is movable through or along the passageway. The passageway is sized to accommodate an IUD such that the IUD is slidable along the passageway. Further, the second end of the introducer that abuts the fundus of the uterus in use is configured to have an increased surface area relative to prior art devices so as to reduce the risk of injury, including perforation of the uterus.

An intrauterine device (IUD) is insertable into a uterus of a mare to suppress estrus and estrus-related behaviors in mares. The IUD may take the form of a weighted ball or sphere that is biocompatible and includes a string attached to the weighted ball for ease of removal by pulling down on the string.

Intrauterine devices and methods for facilitating deployment thereof using a bumper are disclosed. In one embodiment, an intrauterine device comprises a structure including a first central support member and a deployment mechanism coupled to the first central support member. The intrauterine device further comprises a bumper positioned at a distal end of a second central support member and at a more distal position relative to a distal end of the structure so as to prevent the distal end of the structure from contacting the fundus of the uterus of a patient during deployment of the deployment mechanism. In another embodiment, the intrauterine device comprises a bumper coupled to the deployment mechanism and configured to move from a more distal to a more proximal position relative to a distal end of the structure.
