Vascular closure devices and methods of use
A closure device system for sealing a percutaneous puncture in a vessel wall can comprise a toggle configured to engage an interior surface of the vessel wall, a plug configured to engage an exterior surface of the vessel wall, and a suture that extends through the plug and through the toggle along at least a first direction so as to couple the toggle to the plug. The system can further comprise a tube that extends through the plug and through the toggle along the first direction such that a distal end of the tube is disposed distally to the toggle. The tube can define a guidewire lumen that extends therethrough along the first direction. And the guidewire lumen can be configured to receive a guidewire that protrudes from the vessel wall such that the plug, toggle, and tube are slidable along the guidewire toward the vessel wall.
