1. A method of percutaneously sealing an arteriotomy puncture terminating a tissue tract comprising:
inserting a cylindrical base frame having a sealing section coupled thereto, said cylindrical base frame and sealing section defining: an open lumen therethrough, a middle portion, a longitudinal axis, a first radially compact delivery configuration, and a second radially expanded sealing configuration, through a tissue tract and through the arteriotomy puncture in the first radially compact delivery configuration and thence into a vessel to be sealed,
wherein the sealing section allows axial flow of body fluids within the sealing section and prevents flow of body fluids radially through the sealing section in the second radially expanded sealing configuration, wherein the sealing section further includes a tether attached distally to the middle portion of the sealing section, said tether extending through the arteriotomy puncture and tissue tract to a proximal end;
pulling the proximal end of the tether proximally to align the middle portion of the cylindrical base frame in a first radially compact delivery configuration with and against the arteriotomy puncture; and expanding the cylindrical base frame and coupled sealing section from the first radially compact delivery configuration to the second radially expanded sealing configuration, thereby sealing the arteriotomy puncture,
wherein the inserting step is accomplished by passing the cylindrical base frame and sealing section through a lumen of a percutaneous introducer located in the tissue tract,
wherein the cylindrical base frame is stable in the first radially compact delivery configuration and in the second radially expanded sealing configuration, and
wherein the sealing section comprises an expandable plurality of sealing filaments.
