Vascular plug having composite construction
First Claim
1. A device for substantially sealing a wound that extends through tissue to an opening in a body lumen comprising:
- a restraining member comprising a first bioabsorbable material and defining an interior space therein, a sealing member comprising a second bioabsorbable material at least partially located within the interior space of said restraining member, and an elongated tubular member, wherein the restraining member and the sealing member are releasably disposed in an unexpanded state within the elongated tubular member, and wherein at least the sealing member will expand when placed in the body lumen.

Abstract
This invention relates to apparatus and methods for use in sealing a vascular puncture site, particularly sites of punctures that are the result of catheterization or other interventional procedures. In several of the preferred embodiments, the sealing device includes a sealing member and a tether. The sealing member generally performs the function of occupying a space in an incision, puncture, or other wound and sealing the space in the incision, puncture, or wound that it occupies, to prevent further blood flow. The tether is typically attached in some manner to the sealing member, and provides the user with the ability to withdraw the sealing member if necessary. In a particularly preferred form, the sealing device further includes a restraining member associated with the sealing member. The restraining member provides the ability to more securely restrain the sealing member to prevent it from migrating from the deployment location within a tissue tract. The restraining member may also provide an additional capability of manipulating the sealing member after deployment.

14. A device for substantially sealing a wound that extends through tissue to an opening in a body lumen comprising:
- a sealing member, at least a portion of which having a first radial dimension for delivery of said sealing member into the wound and will expand to a second radial dimension upon delivery into said wound and exposure to fluid flow associated with said wound, the second radial dimension being larger than the first radial dimension, and wherein said sealing member comprises a hydrogel, further comprising a restraining member comprising a first bioabsorbable material and defining an interior space therein, said sealing member being located at least partially within the interior space of said restraining member and an elongated tubular member, wherein the sealing device is releasably disposed in a state with the first radial dimension within the elongated tubular member and wherein at least the sealing member will expand to the second radial dimension when placed in the body lumen.
