Described herein is an intravaginal drug delivery system. In an embodiment the intravaginal drug delivery system includes a progestin and estrogen compound, and releases the active ingredients in a fixed physiological ratio over a prolonged period of time to produce a contraceptive state in a female.

An intrauterine device having at least one first pharmaceutically active ingredient and at least one first layer made of at least a first polymeric material, wherein between about 10 and about 60 v/v % of at least one particulate material is dispersed and/or incorporated in the first polymeric material. The presence of the particulate material will reduce the porosity of the polymer or otherwise obstruct the diffusion of the pharmaceutically active ingredient being released, thereby slowing its rate of release. In this way, it is possible to regulate the release rate and/or initial burst of the device, simply by adjusting the amount of particles/particulate material in the first layer, instead of having to adapt the size of the device to the desired release pattern, which requires expensive changes in production equipment and manufacturing processes.

An intrauterine device for preventing egg fertilization having a membrane, a frame having a first arm and a second arm, the first and second arms movable from a first position to a second more expanded position. The frame supports the membrane to move the membrane between a first position to a second more expanded position, wherein the first and second arms are non-planar and each arm has a proximal portion, an intermediate portion and a distal portion, The first arm has a bend at the intermediate portion so that the intermediate portion of the first arm lies in a different plane than the proximal portion of the first arm and the second arm has a bend at the intermediate portion so the intermediate portion of the second arm lies in a different plane than the proximal portion of the second arm. An elongated tail portion extends proximally of the membrane. The membrane can have a convex distal portion.

An intrauterine contraceptive system may include a contraceptive intrauterine device, a retrieval thread permanently attached to the intrauterine device and an insertion device for inserting the intrauterine device into a uterus. The system may also include a release thread releasably coupled with the intrauterine device. The intrauterine device may be deployable out of a distal end of the insertion device and may be configured to change from a delivery configuration when housed in the insertion device to a deployed configuration when deployed in a uterus. The retrieval thread and the optional release thread may be at least partially housed within the insertion device during insertion of the intrauterine device into the uterus. The release thread may extend from the intrauterine device through the insertion device to an attachment point at or near a proximal end of the insertion device.

The present disclosure is related to kits for using an intrauterine system (insertion device) including an intrauterine device (IUD), an insertion device or applicator for inserting the IUD into the cervix of a female patient.

Removable marker implants having fiducial markers disposed on multiple elongate members extend and splay laterally outward when deployed thereby providing improved 3D localization and tracking of a portion of the patient's body for stereotactic radiosurgery. Such an approach is particularly useful for tracking of the uterus during radiosurgery treatment of uterine fibroids. Such implants can include an outer sheath that contains the multiple elongate members during delivery into the portion of the body. The elongate members can be slidably disposed within the shaft and advanced into an expanded deployed position by advancement of an applicator shaft or rod within the sheath. Marker implant can also be integrally formed implants with flexible arms having fiducial markers thereon that can be constrained in a sheath for delivery and resiliently splay laterally outward when released from the shaft. Methods of delivery and deployment are also provided.
