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.
Claims8
A fallopian tube occlusion system comprising:
- a catheter that is sized and shaped to be inserted through a cervix, into a uterus, and guided into a fallopian tube through a tubal ostium;
- and
- an occlusion device including an open walled frame that forms a closed loop path and is characterized by levels of cutbacks with substantially rounded edges, wherein a width of the occlusion device progressively widens down the levels of the cutbacks:
- wherein the frame is constrained within the catheter in a rolled up tubular configuration, and when expelled from the catheter within the fallopian tube opposite side edges of the frame spread out in a plane and the frame assumes a substantially flat configuration within the fallopian tube entirely across x-y dimensions in the plane such that the frame stretches the fallopian tube in one direction, and opposite sides of the fallopian tube are brought into closer proximity to one another;
- wherein opposite side edges of the frame expand from the rolled up tubular configuration to the substantially flat configuration to have a wavy profile.
