Abstract
A method of sealing a vascular puncture of a vessel can include the step of inserting a guidewire through a sheath and into the vessel. The guidewire can include a hollow tube and a balloon coupled to a distal end of the hollow tube. The method can further include the steps of inflating the balloon so as to temporarily occlude the vessel and guiding a closure device along the hollow tube toward the puncture such that a toggle of the closure device enters the vessel through the puncture; and sealing the puncture with the closure device.

A method of sealing a vascular puncture of a vessel, the method comprising the steps of:
- inserting a guidewire through a sheath and into the vessel, the guidewire including a hollow tube and a balloon coupled to a distal end of the hollow tube;
- inflating the balloon so as to temporarily occlude the vessel;
- guiding a closure device along the hollow tube toward the puncture such that a toggle of the closure device enters the vessel through the puncture;
- and
- sealing the puncture with the closure device.
A method of sealing a vascular puncture of a vessel with a closure device having a toggle and a plug, the method comprising the steps of:
- inserting a guidewire through a sheath and into the vessel, the guidewire including a hollow tube and a balloon coupled to a distal end of the hollow tube;
- inflating the balloon so as to temporarily occlude the vessel;
- advancing the hollow tube through the toggle and through the plug;
- guiding the closure device along the hollow tube toward the puncture;
- and
- sealing the puncture with the toggle and the plug.
A vascular closure system configured to seal a puncture in a vessel, the system comprising:
- a guidewire configured to be inserted through the puncture and into the vessel, the guidewire having a hollow tube and an inflatable balloon coupled to a distal end of the hollow tube, the inflatable balloon being configured to occlude the vessel;
- a closure device including a toggle, a plug, and a filament that couples the toggle to the plug, the toggle and plug each defining a respective guidewire channel that is configured to receive the hollow tube such that the closure device is advanceable along the hollow tube toward the puncture.
