Three-needle closure device

A vascular closure system, comprising:

• a sheath including three hollow lobes;
• a guiding device disposed within one of the hollow lobes, wherein the guiding device further includes:
• an access needle;
• a guide wire configured to conform to the shape of the interior surface of a vessel;
• an expandable needle disposed within a different one of the hollow lobes, wherein the expandable needle further includes:
• a needle tip configured to pierce the surface of a vessel;
• an expandable mesh that includes an expanded state and an extended state;
• an insertion rod configured to insert the expandable needle without expanding the expandable mesh;
• an actuator configured to expand the expandable mesh into the expanded state;
• a hooking device disposed within yet another different one of the hollow lobes, wherein the hooking device is configured to hook the expandable needle, wherein the hooking device further includes:
• a curved hollow needle configured to pierce the surface of a vessel;
• a suture extending through the curved hollow needle;
• and
• a suture extending through the curved hollow needle and a toggle connected to the suture and disposed on the end of the curved hollow needle.

A method of performing a medical procedure via a vessel opening, comprising:

• extending a suture across a vessel opening;
• pushing the suture to a side of the vessel opening;
• dilating the opening by inserting a sheath into the vessel opening;
• performing a medical procedure via the sheath subsequent to at least the step of extending a suture across a vessel opening;
• removing the sheath from the vessel opening;
• cinching the suture to approximate tissue surrounding the vessel opening.
