  • Publication number: 20250241784
    Abstract: Systems, devices, and methods for delivering one or multiple materials into a body space (e.g., to occlude the body space) and/or for removing one or multiple materials from a body space (e.g., to open or reopen the body space) are described. Delivering material into the vas deferens of the male reproductive tract for contraception, removing material from the vas deferens to restore patency of the vas deferens, delivering material into the fallopian tubes of the female reproductive tract for contraception, and removing material from fallopian tubes to restore patency of the fallopian tubes is described. Confirming access to a body space is described. Agitating materials in a body space is described. Creating turbulence in a body space is described.

  • Publication number: 20250134701
    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.

  • Patent number: 10639031
    Abstract: 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.
