Claim Text:
1. A method for sealing a puncture, having an edge, in a wall of a lumen of a body comprising: a) deploying a deployment member of a sealing device through an elastic membrane adjacent an outer wall of the lumen and the puncture, wherein the sealing element is disposed within a distal portion of the deployment member and wherein the distal portion of the deployment member has a uniform diameter greater than the sealing element; b) positioning the sealing element adjacent the outer wall of the lumen and the edge of the puncture such that a maximal radial diameter portion of the sealing element is located outside the lumen and a reduced radial portion of the sealing element is located within the lumen; c) partially withdrawing the sealing element such that a portion of the reduced radial portion of the sealing element is disposed within the lumen and the remaining portion within the puncture; d) frictionally engaging the membrane with the deployment member; e) retracting the deployment member relative to the sealing element while maintaining the uniform diameter of the deployment member to stretch the membrane away from the wall of the lumen; f) disengaging the deployment member from the membrane wherein the membrane elastically holds the sealing member within the puncture and partially within the lumen; and g) retracting the device from the body to leave the maximal radial diameter portion of the sealing element outside the lumen adjacent the outer wall and the edge of the puncture.
