Plug with collet and apparatus and methods for delivering such plugs
First Claim
1. A device for sealing a passage through tissue, comprising:
- a generally annular body comprising a proximal end, a distal end, and a lumen extending between the proximal and distal ends, the lumen comprising a reduced cross-sectional region, wherein the annular body has an outer profile that tapers to the distal end; and
a generally annular sealing member slidably disposed within the lumen of the body, the sealing member comprising a lumen extending between proximal and distal ends thereof, and a plurality of shoulders disposed about the lumen of the sealing member, the shoulders being deflectable towards one another when the sealing member is moved at least partially into the reduced cross-sectional region, thereby at least partially sealing the lumen of the sealing member,said sealing member being more flexible than said body and said sealing member having a distal end with a continuous outer perimeter and a diameter greater than a minimum diameter of the lumen of said body.

Abstract
An apparatus for sealing a passage through tissue includes a plug including external threads, a lumen extending between its proximal and distal ends, and an annular collet slidably disposed within the lumen. The plug is carried on a distal end of a handle device that includes an inner member with a distal end that is slidable axially within the lumen of the body for moving the collet into a reduced cross-sectional region of the lumen, thereby compressing the collet to seal the lumen, and for deploying the plug from the handle device. During use, the plug is delivered into a passage through tissue over a guide wire. Once a desired location is reached, the plug is deployed from the handle device, thereby compressing the collet and sealing the lumen. The guide wire and handle device are removed, leaving the plug to seal the passage.
