Plug with collet and apparatus and method 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; 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.

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 threaded 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.

13. An apparatus for sealing a passage through tissue, comprising:
-
a plug member comprising a generally annular body including a lumen extending between proximal and distal ends thereof, the lumen comprising a reduced cross-sectional region, and a generally annular sealing member slidably disposed within the lumen of the body, the sealing member comprising a plurality of shoulders disposed about a lumen of the sealing member, the shoulders being deflectable towards one another for at least partially sealing the lumen of the body; and
a handle device comprising an outer member and an inner member including proximal and distal ends defining a longitudinal axis therebetween, the distal end of the outer member being detachably coupled to the proximal end of the body, the distal end of the inner member being slidable axially within the lumen of the body for at least partially moving the sealing member into the reduced cross-sectional region of the lumen in the body, thereby deflecting the shoulders towards one another to at least partially seal the lumen in the body. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method for sealing a passage through tissue from a patient'"'"'s skin to a body lumen, comprising:
-
providing a guide wire element extending from the patient'"'"'s skin through the passage and into the body lumen;
advancing a plug member into the passage over the guide wire element, the plug member comprising a lumen through which the guide wire element is inserted as the plug member is advanced into the passage, the plug member comprising a sealing member therein at least partially surrounding the guide wire element;
directing the sealing member into a reduced cross-sectional region of the lumen, thereby deflecting a plurality of shoulders on the sealing member towards one another to at least partially seal the lumen; and
withdrawing at least a portion of the guide wire element from the passage. - View Dependent Claims (22, 23, 24, 25)
