Female Contraceptives TRIZ Cases
- Intra-Orifice Osmotic Medicament Delivery for Controlled Release
An osmotic intra-orifice housing uses semipermeable membrane uptake to drive controlled drug release, increase loading flexibility, and avoid reuse.
- Locking Intrauterine Frame for Low-Diameter Cervical Insertion
A flexible intrauterine frame uses locking parts and a removal thread to pass the cervix with less discomfort and lower uterine penetration risk.
- Postpartum IUD Placement Tube With Rotation-Constrained Insertion
A sterilized placement tube constrains IUD rotation and string position to enable hygienic postpartum insertion with less trauma and easier retrieval.
- Shape-Memory IUD Expansion to Limit Uterine Migration
A shape-memory IUD expands against the uterine wall to limit migration while enabling focal copper delivery with less exposure and insertion discomfort.
- IUD String Grasper With Camera Guidance for Self-Removal
A grasper, camera, and guided home-use kit help patients secure IUD strings and remove the device safely when clinic access is limited.
- Wireless-Powered Intra-Uterine Monitoring for Long-Term Contraception
Wireless electromagnetic charging lets an IUD monitor uterine conditions long term without an internal battery, reducing size and leakage risk.
- IUS Inserter Slider Locking for Accurate String-Guided Placement
A slider-controlled string lock keeps the intrauterine system stable during insertion, reducing misalignment, jamming, and string damage.
