Device for sealing percutaneous puncture in a vessel
First Claim
1. A device for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being, said device comprising first means having an outlet at the distal end thereof and adapted to be inserted through said incision or puncture so that said outlet is located within the interior of said vessel, expandable closure means disposed within said first means and being formed of a material which is held in a compact configuration within said first means, ejecting means for causing said closure means to pass out of said outlet into the interior of said vessel, said closure means being expandable to expand to form an engagement surface, said engagement surface conforming to the arcuate inner surface of said vessel contiguous with said incision or puncture, and retraction means for moving said closure to said opening after said first means has been removed therefrom, whereupon said engagement surface hemostatically engages said arcuate inner surface of said vessel contiguous with said incision or puncture to seal said incision or puncture, said retraction means serving to hold said closure in place and without said closure appreciably blocking the flow of blood through said vessel.

Abstract
A device for sealing an opening or puncture in the wall of a blood vessel, duct or other lumen of a living being. The device includes an elongated tubular body having an outlet at the distal end thereof and which is arranged to be inserted, such as percutaneously, through the puncture in the blood vessel so that the outlet is located within the vessel'"'"'s interior. An expandible closure is disposed within the tubular body and is formed so as to be held in a compact configuration therein. The tubular body also includes ejecting means for forcing the closure out of the outlet into the interior of the blood vessel, whereupon the closure automatically expands to form an enlarged engagement surface. A retraction filament is secured to the closure for pulling it to the puncture after the tubular body has been withdrawn from the puncture so that the engagement surface of the closure means hemostatically engages the inner surface of the blood vessel contiguous with the puncture. The filament held taut and taped or otherwise secured in place on the patient'"'"'s skin to hold the closure in position. The closure and filament are each formed of a biodegradable material to enable the closure to be left in place. Preferably the closure also includes a non-thrombogenic coating on its surface. The closure is constructed so that when it is opened and is in place sealing the puncture in the blood vessel it doesn'"'"'t appreciably block the flow of any blood through the blood vessel.

A device for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being, said device comprising first means having an outlet at the distal end thereof and adapted to be inserted through said incision or puncture so that said outlet is located within the interior of said vessel, expandable closure means disposed within said first means and being formed of a material which is held in a compact configuration within said first means, ejecting means for causing said closure means to pass out of said outlet into the interior of said vessel, said closure means being expandable to expand to form an engagement surface, said engagement surface conforming to the arcuate inner surface of said vessel contiguous with said incision or puncture, and retraction means for moving said closure to said opening after said first means has been removed therefrom, whereupon said engagement surface hemostatically engages said arcuate inner surface of said vessel contiguous with said incision or puncture to seal said incision or puncture, said retraction means serving to hold said closure in place and without said closure appreciably blocking the flow of blood through said vessel.
- 15. A method for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being to preclude the flow of blood from said vessel through said incision or puncture by introducing plug means therein, said plug means having a shape which when said plug means is in place conforms to the arcuate inner surface of said vessel contiguous with said incision or puncture, said method comprising introducing said plug means into said vessel, with a portion of said plug means extending through said incision or puncture and causing said plug means to engage the arcuate inner surface of said vessel contiguous with said incision or puncture to seal said incision or puncture while not appreciably restricting the flow of blood through said vessel, and thereafter leaving said plug means in place therein, whereupon said incision or puncture is permanently sealed against the flow of blood therethrough.
- 20. A device for sealing a percutaneous incision or puncture in the wall of a blood vessel of a living being comprising introducer means for introducing plug means through said incision or puncture and into the interior of said vessel, said plug means being configured to conform to the arcuate inner surface of said vessel contiguous with said incision or puncture and comprising a first portion extending into said incision or puncture and a second portion engaging the arcuate inner surface of said vesel contiguous with said incision or puncture to seal said incision or puncture while not appreciably restricting the flow of blood through said vessel.
