  • Patent number: 8336552
    Abstract: The present invention comprises systems, methods and devices for the delivery of compositions for occluding or of elements for opening conduits. The implantable occlusive material may be delivered pre-formed or in situ cured and, may be a resorbable or degradable material that supports tissue ingrowth or wound healing or a similar response that replaces the cured occlusive material leaving little or no original occlusive material in place. The delivery system is positioned to allow for placement of the occlusive material into the body conduit. Use of delivery systems, methods and devices for re-opening an occluded body conduit are also included.
