Abstract
Delivery systems for providing occlusive hydrogels in a tube lumen or void space within the body including but not limited to a reproductive tract such as the vas deferens or fallopian tubes for contraception are described. The delivery systems contain mechanisms that confirm proper placement of the system in the bodily lumen prior to the delivery of the occlusive material. The systems also can contain a confirmatory mechanism that demonstrates the blockage or occlusion in the bodily lumen has been achieved following the deposition of the occlusive material. Another aspect of this application is to provide a removal system that delivers dissolving material, agitates, aspirates, and confirms the patency of the bodily lumen following the removal of the occlusive material if so desired by the patient for the return to fertility.
