A birth control assembly for inhibiting sperm from entering a uterus includes a tube that may be inserted into a cervix. A valve is coupled to the tube. The valve inhibits sperm from entering the tube thereby facilitating the tube to control birth. The valve facilitates menstrual fluid to exit the cervix.

A medical device and method for artificial insemination are provided. The medical device has a shield and an arm secured to the shield at one end and extending outwardly from the shield. The arm is inserted into the cervical canal of a patient and the shield covers the external os of the patient. By inserting the medical device into a patient's cervical canal after insemination, a physical barrier that holds a semen sample within the cervical canal and prevents leakage from the cervical canal back into the vaginal cavity is established. The device may have a bore extending through the device for a catheter to pass through. The bore has a valve to allow passage of the catheter and prevent backflow of semen. The arm may have a circumferential bulge to help keep the device in place during use.

An endocervical seal has a sleeve with a passageway for receiving an intrauterine interventional or diagnostic tool. The sleeve has a coaxially disposed outer balloon with a distal portion configured to inflate in a cervical os and a proximal portion configured to inflate in a cervical canal.

Devices for reducing the risk of pregnancy complications, including preterm labor and preterm birth, are disclosed herein. Also disclosed are devices in combination with therapies and medicaments for the treatment of pregnancy complications. Also disclosed are methods of using the devices for the treatment of pregnancy complications.

An everting balloon system is disclosed that can be used for the placement of an IUD within the uterine cavity of a female patient. The everting balloon system with IUD can be used to access a uterine cavity at specific locations in the fundus. A one-handed IUD delivery system for placement with an everting catheter is disclosed. An IUD loading system for placement within an everting catheter is disclosed. The everting catheter with an IUD can simplify the process of IUD placement within the uterine cavity.

Implementations of the present disclosure may include a non-hormonal contraceptive, including a body formed of one or more non-porous, biocompatible materials. In some implementations, the body has a length in a range from 1 centimeter to 31 centimeters. In some implementations, the body has a width in a range from 0.5 centimeters to 10 centimeters. Various implementations may also include a copper inlay on the body, the copper inlay having an exposed surface area in a range from 200 square millimeters to 1000 square millimeters.
