Methods and devices to control movement of microorganisms, sperm or viruses within a female reproductive system, including methods and devices for preventing infection or pregnancy. Devices may include a cervical barrier that is configured to allow biological fluids to exit the uterus and cervical canal while preventing the ascension of microorganisms, sperm or viruses into the cervical canal and uterus.

A cervical cup includes a body having a flange and a vacuum port so that application of a vacuum to the port will secure the cervical cup to a cervix disposed inside of the body of the cup. Example of the disclosed methodology to treat preterm birth includes inserting of a cervix into a cervical cup and applying a vacuum to a vacuum port of the cervical cup so as to secure the cervical cup to the cervix.

An auxiliary shaping device for cervical vaginal penetration plasty and a use method thereof. The auxiliary shaping device includes a uterine cavity support, a cervical canal support and a vaginal support which are made of elastic material. The uterine cavity support is a hollow bowl-shaped structure; the uterine cavity support includes a first end and a second end; the first end has a larger diameter than the second end; the first end includes a plurality of valve bodies evenly distributed in circumferential direction; a concave part is arranged between two adjacent valve bodies, the concave part has an opening shape; uterine cavity secretions enter an interior of the uterine cavity support through the concave part; one end of cervical canal support is connected with the second end, other end is connected with vaginal support; a passage is arranged in the uterine cavity support; cervical canal support and vaginal support.

A device for retarding birth including an upper ring for surrounding a cervix, an anchoring component for anchoring the device, and an elastic component for attaching the upper ring to the anchoring component, wherein the elastic component pushes the upper ring and the anchoring component apart. A device for retarding birth including a sleeve for surrounding a cervix along a greater portion of a length of the cervix, a support strip on the sleeve directed along an axis of the sleeve, and a ring at least partially around the sleeve, in which when a top of the sleeve is pushed to expand radially, the support strip pivots on the ring, such that an end of the support strip near the top of the sleeve moves radially outward, and an end of the support strip near the bottom of the sleeve moves radially inward. Related apparatus and methods are also described.

A drug delivery system is provided in the form of a controlled release, bioerodible pellet for subdermal implantation. The pellet is bioerodible, and provides for the sustained release of a pharmacologically active agent over an extended time period. As such, the drug delivery system finds significant utility in chronic drug administration. Bioerosion products are water soluble, bioresorbed, or both, obviating the need for surgical removal of the implant. Methods for manufacturing and using the drug delivery system are also provided.

A collapsible pessary is provided, and can have a stem and at least one rotating petal member that can rotate between a collapsed state with a smaller diameter and a deployed state with a larger diameter. The collapsible pessary can have a plunger within the stem, and pushing the plunger upwards can cause the plunger to push upwards on a portion of the petal member, thereby causing the petal member to rotate into a deployed position. The pessary can be in a collapsed state wherein its overall diameter is at a minimum, or a deployed state, wherein its overall diameter is at a maximum.
