Abstract

A device for sealing a puncture opening may include a base frame having a delivery configuration, wherein the base frame is retracted to have a relatively smaller overall profile, and a deployed configuration, wherein the base frame is extended to have a relatively larger overall profile. The base frame is sized to engage an interior surface of the blood vessel wall in the deployed configuration. A sealing section is coupled to the base frame, the sealing section having an initial configuration, wherein the sealing section permits fluid flow, and a barrier configuration, wherein the sealing section prevents fluid flow. The sealing section in the barrier configuration is sized to block fluid flow through the puncture opening when the base frame is in the deployed configuration.

Claims

1. A sealing device for percutaneously sealing a puncture opening in a wall of a blood vessel, the sealing device comprising:

a cylindrical base frame having a sealing section coupled thereto and defining a longitudinal axis;

wherein the base frame is movable between a delivery configuration in which the base frame is retracted to have a relatively smaller overall profile and a deployed configuration in which the base frame is extended to have a relatively larger overall profile;

wherein the base frame is sized to engage an interior surface of the blood vessel wall when in the deployed configuration;

wherein the sealing section is configured to prevent fluid flow through the puncture opening while permitting fluid flow through the blood vessel in the deployed configuration;

further including a tether attached at a middle portion of the sealing section;

wherein the tether extends away from the middle portion of the sealing section transversely relative to the longitudinal axis;

wherein the sealing section comprises a bi-stable sealing structure having a first stable state corresponding to an initial configuration and a second stable state corresponding to a barrier configuration;

wherein the sealing section comprises a plurality of braided sealing filaments;

wherein the sealing filaments comprise an expandable material, wherein each filament has a smaller volume in the initial configuration and a larger volume in the barrier configuration;

wherein the expandable material comprises an electroactive polymer that selectively moves from the initial configuration to the barrier configuration in response to an electric current supplied to the expandable material.
