Vascular sealing device

A vascular sealing device, comprising:

• a guidewire adapted to be deployable into a blood vessel through a vascular access point of a subject;
• a sheath member defining a hollow cavity along a length of the sheath member, the hollow cavity configured to allow insertion of the guidewire therein, wherein the sheath member is deployable from the guidewire and configured to be positioned in a lumen of the blood vessel;
• and
• at least one occlusion plug deployable from the sheath member and configured to be positioned at the lumen of the blood vessel, the at least one occlusion plug comprising:
• a first occlusion plug comprising a first shaft member and a first occluding member mounted to a distal end of the first shaft member, wherein the first occlusion plug is deployable through the sheath member and configured to be positioned within the lumen of the blood vessel, and
• a second occlusion plug comprising a second shaft member and a second occluding member mounted to a distal end of the second shaft member, wherein the second occlusion plug is deployable through the sheath member and configured to be positioned at an exterior portion of the lumen of the blood vessel,
• wherein the at least one occlusion plug is configured to selectively operate in an inflated configuration and a deflated configuration to apply a controlled pressure to an interior portion of the blood vessel and the exterior portion of the blood vessel at the vascular access point to occlude the vascular access point of the blood vessel.
