Abstract
Methods for sealing a percutaneous puncture in a wall of a body passageway are disclosed herein. The methods include inserting a deployment instrument into the puncture via a toggle along the guidewire, and actuating the deployment instrument to move the first component and the second component relative to each other such that the toggle abuts the wall of the artery proximate the puncture to seal the puncture.
Claims19
A method of sealing a puncture in a wall of an artery, the method comprising:
- inserting a guidewire into the puncture such that the guidewire extends from outside the artery, through the puncture and into the artery;
- inserting a deployment instrument into the puncture via a toggle along the guidewire, the deployment instrument having a distal end section including a first component and a second component being in actuatable relationship to one another, wherein one of the first component of the second component rigidly supports the toggle, and the toggle is at least partially received in the other of the first component or the second component;
- and
- actuating the deployment instrument to move the first component and the second component relative to each other such that the toggle abuts the wall of the artery proximate the puncture.

A method of sealing a percutaneous puncture in a wall of an artery, comprising:
- inserting a deployment instrument along a guidewire through the puncture into the artery, the deployment instrument carrying a tensioner assembly and a closure device including a toggle, a plug and a continuous elongate filament configured to draw the plug towards the toggle upon the application of tension to the filament in a direction away from the toggle;
- positioning a distal end of the deployment instrument such that the toggle is positioned in the artery;
- and
- pulling the tensioner assembly away from the puncture while the filament is connected to the tensioner assembly such that a mechanically induced tension force is applied to the filament such that the tension force increases with increasing distance of the tensioner assembly away from the puncture to draw the toggle and the seal towards each other and into engagement with the wall of the artery at respectively opposite sides of the wall, wherein the plug has an aperture configured to receive the guidewire, such that the toggle and the plug are slidable along the guidewire when toggle is inserted into the artery.

A method of sealing a percutaneous puncture in a wall of an artery, comprising:
- inserting a deployment instrument along a guidewire through the puncture into the artery, the deployment instrument carving a tensioner assembly and a closure device including a toggle, a plug and a continuous elongate filament configured to draw the plug towards the toggle upon the application of tension to the filament in a direction away from the toggle;
- positioning a distal end of the deployment instrument such that the toggle is positioned in the artery;
- and
- pulling the tensioner assembly way from the puncture while the filament is connected to the tensioner assembly such that a mechanically induced tension force is applied to the filament such that the tension force increases with increasing distance of the tensioner assembly away from the puncture to draw the toggle and the seal towards each other and into engagement with the wall of the artery at respectively opposite sides of the wall, wherein the toggle includes a cavity, and inserting the toggle of the closure device into the artery includes positioning the guidewire through the cavity of the toggle so that the toggle slides along the guidewire.

- locking the plug and the toggle in place along the filament to seal the puncture;
- and
- removing the guidewire from the toggle and the artery.
