Occlusion implant

Abstract

Contraceptive and/or sterilization methods and devices are disclosed which may improve the speed of tubal occlusion and mechanisms for anchoring for a contraceptive device. In accordance with some embodiments, improvements may be made to the delivery catheter to induce trauma and create faster tubal occlusion, improvements may be made to the occlusion device to prevent migration and induce trauma, and improvements may be made to the occlusion device to reduce the total volume of in-growth required compared to conventional expansive occlusion devices.
