## Abstract

A set of devices and associated methodology for percutaneously closing a puncture through the wall of an artery. The method includes inserting a guide wire through a percutaneous entry and into the artery; using the guide wire to guide an insertion of an introducer catheter into the artery; inserting a balloon catheter through the introducer catheter and into the artery; obtaining a tube having a clamp configured to selectively clamp to the introducer catheter; loading the tube with a plurality of fasteners, each fastener individually tethered to a suture; clamping the tube loaded with fasteners onto the introducer catheter, thereby aligning the puncture with a distal working end of the tube; ejecting two or more of the fasteners from the tube to attach onto the artery; percutaneously tying together the tethered sutures of the attached fasteners to draw the attached fasteners together, closing the puncture.

## Claims

### Claim 1

A method for percutaneously closing a puncture through the wall of an artery, comprising:
inserting a guide wire through a percutaneous entry and into the artery;
using the guide wire to guide an insertion of an introducer catheter into the artery;
inserting a balloon catheter through the introducer catheter and into the artery;
locking a firing mechanism loaded with fasteners onto the introducer catheter, thereby aligning the puncture with a distal working end of the firing mechanism;
activating the firing mechanism to fire two or more fasteners onto the artery, each fastener individually tethered to a suture;
percutaneously tying the sutures together to draw the fasteners together, closing the puncture.
