A recently granted patent (Publication Number: US11871916B2) discloses a method for closing a blood vessel puncture site using a closure device equipped with an expansible member and a tensioning coil. The method involves deploying the expansible member within the blood vessel, retracting the closure device to seat the expansible member against the puncture site, and using the tensioning coil to gauge and apply appropriate tension to prevent excessive force during the closure process. Additionally, the tensioning coil provides compliance to patient movement, preventing the closure device from being dislodged.

Furthermore, the method includes positioning a chemical and/or biological agent release region proximal to the expansible member, coated on the tensioning coil, at a predetermined distance from the puncture site. The tensioning coil not only applies tension to the expansible member but also elongates based on the applied tension, with a specified range of tension from about 0.5 ounce to 30 ounces. After achieving hemostasis in the tissue tract, the tensioning coil is released, collapsing the expansible member, and allowing for the retraction of the closure device, including both the expansible member and the tensioning coil, from the tissue tract.
