Abstract
Abstract A method and apparatus for percutaneous arterial closure with staples. The apparatus comprises a triple lumen catheter, two j-shaped guide wires, a vascular stapler, and a tubular member. The method and apparatus provide for closure of arterial punctures that are typically created during catheterization. The method and apparatus provide a percutaneous method that reduces the likelihood of bleeding and the formation of false aneurysms. The method comprises inserting the triple lumen catheter in the arterial opening to deploy a pair of guide wires having projections at the end. The catheter is removed and the projections on the end of the guide wires are engaged with the arterial wall around the opening. The guide wires are then twisted to close the opening. Next, a stapler is moved down the guide wires to the site of the opening where staples are inserted to close the opening. Then, the tubular member slides over the guide wires and straightens the projections for removal from inside the artery. The tubular member and the guide wires are then removed from arterial opening and the skin is closed with a normal staple.
