Patent ID: 8529598

Claim:
A device for deploying a biodegradable plug assembly to seal an opening in a vessel wall or an adjacent tissue tract, the device comprising: a biodegradable plug assembly comprising an anchor, a filament, a biodegradable plug member, and a locking element; a device sheath having a proximal end, a distal end, and a lumen extending therebetween, wherein the device sheath is configured to deliver the biodegradable plug assembly to the opening or tissue tract for deployment; a device handle coupled to the proximal end of the device sheath, wherein the device handle includes a plunger configured to deploy the biodegradable plug assembly into the opening or tissue tract; and an insertion sheath operatively connected to the device handle, wherein the device sheath is configured to be disposed within the insertion sheath, wherein the insertion sheath and the device handle cooperate to automatically seat the anchor against a distal end of the insertion sheath when the device sheath is inserted into the insertion sheath, wherein the device handle further comprises a torsion spring locking element and a torsion spring engaged with a control disc; wherein inserting the device sheath into the insertion sheath disposes a proximal end of the insertion sheath within the device handle; wherein the proximal end of the insertion sheath is configured to engage the torsion spring locking element to release the torsion spring which thereby rotates the control disc within the device handle to lock the insertion sheath to the device handle.
