Devices for sealing openings through tissue and apparatus and methods for delivering them
First Claim
1. In an apparatus for sealing a passage through tissue which communicates with a body lumen, the improvement comprising:
- an elongate shaft having a proximal end and a distal end;
an opening in the proximal region of the elongate shaft, a plug member disposed on the distal end of the elongate shaft, the elongate shaft having a cross-section that is substantially smaller than a cross-section of the plug member, and an opening in the distal region of said plug, wherein said plug member and said elongate shaft have a position indicating lumen therein which extends from the opening in the distal region of said plug to the opening in the proximal region-of said elongate shaft.

Abstract
An apparatus for sealing a passage through tissue includes an elongate shaft and a cylindrical plug disposed on a distal end of the shaft, the plug including a helical thread on its outer surface. Intestinal submucosa may be secured to the plug, e.g., in a cavity in its distal end, that may be delivered into the passage. Alternatively, the plug may be formed from a bioabsorbable material and may be released from the shaft within the passage. The plug is threaded into the passage, thereby engaging the tissue to seal the passage. The shaft is rotated until it engages a blood vessel within the tissue while monitoring blood flow through the vessel. The shaft is rotated to thread the plug into the passage until blood flow ceases through the vessel, whereupon rotation of the shaft is reversed to back the plug until blood flow through the vessel resumes.

11. In an apparatus for sealing a passage through tissue which communicates with a body lumen, the improvement comprising:
-
an elongate shaft having a proximal end and a distal end;
an opening in the proximal region of the elongate shaft, a plug member substantially permanently attached to the distal end of the elongate shaft, and an opening in the distal region of said plug, wherein said plug member and said elongate shaft have a position indicating lumen therein which extends from the opening in the distal region of said plug to the opening in the proximal region of the elongate shaft. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
