Plug with detachable guidewire element and methods for use
First Claim
1. An apparatus for sealing a passage through tissue in a body, comprising:
- an elongate delivery device comprising a lumen extending between proximal and distal ends thereof, and defining a longitudinal axis;
a plug member detachably carried by the distal end of the delivery device and comprising a lumen communicating with the lumen of the delivery device, wherein the plug member is configured to be inserted through the tissue; and
a guide wire element comprising a proximal end receivable through the lumens in the plug member and the delivery device, the guide wire element comprising a first and second portion slidable relative to each other and a plurality of lateral elements on a distal portion thereof, the plurality of lateral elements being deflectable from an expanded configuration towards a collapsed configuration within the body substantially parallel to the delivery device such that relative motion between the first and second portion of the guide wire element causes the lateral elements to deflect.

Abstract
An apparatus for sealing a passage through tissue includes a bioabsorbable, threaded plug carried by a delivery device. A guide wire is receivable through lumens in the plug and delivery device that includes wings on a bioabsorbable distal portion. With the wings collapsed, the guide wire is advanced through the passage into a blood vessel, the wings expanding once located within the vessel, and the guide wire is withdrawn until the wings contact the vessel wall. The plug is threaded into the passage over the guide wire until the plug is disposed adjacent the wings. The distal portion of the guide wire is secured to the plug, e.g., by compressing a collet within the plug lumen that seals the lumen, and is severed from a proximal portion thereof. Thus, the plug and distal portion are deployed with the plug sealing the passage.

6. A method for sealing a passage through tissue from a patient'"'"'s skin to a body lumen, comprising:
-
advancing a distal end of a guide wire element from the patient'"'"'s skin through the passage and into the body lumen, the guide wire element comprising a plurality of lateral elements on the distal end of the guide wire element and also comprising a distal portion separately coupled to a proximal region; partially withdrawing the guide wire element from the body lumen until the plurality of lateral elements contact a wall of the body lumen; inserting a proximal end of the guide wire element into a lumen of a plug member carried in a lumen of an elongated delivery device; advancing the plug member and delivery device into the passage over the already advanced guide wire element; securing a distal portion of the guide wire element relative to the plug member with the plurality of lateral elements disposed substantially against the wall of the body lumen; and decoupling and removing a portion of the guide wire element from the passage. - View Dependent Claims (7, 8, 9)
