Abstract
The sealing device is composed of an intra-arterial occluder and an extra-arterial occluder, both made of resilient biocompatible and/or bioabsorbable material and held in place via a saw-toothed guide extending integrally from the intra-arterial occluder. An insertion tool is provided to effect sliding of the extra-arterial occluder over the guide and fixation of the extra-arterial occluder to the guide in sealed relation over an opening in body tissue and safe cutting of the guide. A force gauge is provided on the tool to indicate the sealing pressure on the intra-arterial occluder.
