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.

Apparatus and method for delivery and/or removal of occlusions in the body

A delivery system for delivering a plurality of helical tissue anchors to repair a wall defect. Coaxially contained within the outer sheath are inner tubular members. The first inner tubular member designed to deploy a first helical tissue anchor, a second inner tubular member designed to deploy a second helical tissue anchor, and a centered inner tubular member contains a cinching mechanism. The two helical tissue anchors are connected to a suture or strap that pull the two helical tissue anchors together to close a tissue defect. A cinching mechanism holds the anchors and tissue defect together and cut the suture or strap.

Helical tissue anchor device and delivery system

Disclosed is a handle mechanism, including: a body, a first anchor delivery device provided to the body, a second anchor delivery device provided to the body, a tightening device provided to the body, and a locking and cutting device provided to the body. The first anchor delivery device is configured to control a first tissue anchor. The second anchor delivery device is configured to control a second tissue anchor. The tightening device is configured to pull a suture member.
