1. A device for sealing and/or closing an opening in a vessel wall and/or an adjacent tissue tract, the device comprising: an anchor;a filament including a first end, a second end, and a length extending therebetween, wherein the first end of the filament is coupled to the anchor;a biodegradable plug disposed about the filament adjacent to the anchor, wherein the plug include an elongate member including a first end and a second end, wherein the first end is adjacent to the anchor, wherein the plug is configured to compress when deployed in the tissue tract and/or opening in the vessel wall such that the second end moves towards the first end over the filament; anda device sheath having a proximal end, a distal end, and a lumen extending therebetween, wherein the device sheath is configured to deliver the anchor, plug, and/or filament to the tissue tract and/or vessel opening for deployment; anda device handle coupled to the proximal end of the device sheath, wherein the device handle includes a plunger configured to deploy the anchor, plug, and/or filament into the tissue tract and/or opening in the vessel wall; andan insertion sheath, wherein the device sheath is disposed within the insertion sheath, wherein the anchor is configured to automatically seat against a distal end of the insertion sheath when the device sheath is inserted into the insertion sheath and the insertion sheath is subsequently locked to the device handle;wherein the device handle includes a plunger protection mechanism to prevent premature compression of the plug; andwherein the plunger protection mechanism includes a clip and a pin, the clip having a first end coupled to the plunger and a second end configured to releasably engage the pin, wherein the pin is secured relative to the device handle, wherein when the clip is engaged to the pin, the plunger is in a depressed position to prevent premature deployment of the anchor, plug, and filament, wherein when the clip is disengaged from the pin, the plunger is in a second non-depressed position. 2. A device for sealing and/or closing an opening in a vessel wall and/or an adjacent tissue tract, the device comprising: an anchor configured to engage an interior surface of the vessel wall;a filament including a first end, a second end, and a length extending therebetween, wherein the first end of the filament is coupled to the anchor;a biodegradable plug disposed about the filament adjacent to the anchor, wherein the plug include an elongate member including a first end and a second end, wherein the first end is adjacent to the anchor;a locking element disposed about the filament proximal of the plug, wherein the locking element is configured to secure the plug to the anchor;a device sheath having a proximal end, a distal end, and a lumen extending therebetween, wherein the device sheath is configured to deliver the anchor, plug, and/or filament to the tissue tract and/or vessel opening for deployment;a device handle coupled to the proximal end of the device sheath, wherein a portion of the filament is releasably coupled to the device handle and/or the device sheath, wherein the device handle includes a plunger configured to deploy the anchor, plug, and/or filament into the tissue tract and/or opening in the vessel wall, wherein the portion of the filament that is releasably coupled to the device handle and/or the device sheath is configured to be released from the device handle and/or device sheath when the anchor, plug, and/or filament are deployed;a tubular member having a proximal end coupled to the device handle and a distal end coupled to the filament; anda push rod having a proximal end coupled to the plunger and a distal end configured to compress the plug against the anchor when the plunger is actuated, wherein the push rod includes a bead intermediate the proximal end and distal end, wherein the bead is configured to release the filament from the tubular member. 3. A device for sealing and/or closing an opening in a vessel wall and/or an adjacent tissue tract, the device comprising: an anchor configured to engage an interior surface of the vessel wall;a filament including a first end, a second end, and a length extending therebetween, wherein the first end of the filament is coupled to the anchor;a biodegradable plug disposed about the filament adjacent to the anchor, wherein the plug include an elongate member including a first end and a second end, wherein the first end is adjacent to the anchor;a locking element disposed about the filament proximal of the plug, wherein the locking element is configured to secure the plug to the anchor;a device sheath having a proximal end, a distal end, and a lumen extending therebetween, wherein the device sheath is configured to deliver the anchor, plug, and/or filament to the tissue tract and/or vessel opening for deployment; anda device handle coupled to the proximal end of the device sheath, wherein a portion of the filament is releasably coupled to the device handle and/or the device sheath, wherein the device handle includes a plunger configured to deploy the anchor, plug, and/or filament into the tissue tract and/or opening in the vessel wall, wherein the portion of the filament that is releasably coupled to the device handle and/or the device sheath is configured to be released from the device handle and/or device sheath when the anchor, plug, and/or filament are deployed;wherein the device handle includes a plunger protection mechanism to prevent premature compression of the plug; andwherein the plunger protection mechanism includes a clip and a pin, the clip having a first end coupled to the plunger and a second end configured to releasably engage the pin, wherein the pin is secured relative to the device handle, wherein when the clip is engaged to the pin, the plunger is in a depressed position to prevent premature deployment of the anchor, plug, and filament, wherein when the clip is disengaged from the pin, the plunger is in a second non-depressed position. 4. A device for sealing and/or closing an opening in a vessel wall and/or an adjacent tissue tract, the device comprising: an anchor configured to engage an interior surface of the vessel wall;a filament including a first end, a second end, and a length extending therebetween, wherein the first end of the filament is coupled to the anchor;a biodegradable plug disposed about the filament adjacent to the anchor, wherein the plug include an elongate member including a first end and a second end, wherein the first end is adjacent to the anchor;a device sheath having a proximal end, a distal end, and a lumen extending therebetween, wherein the device sheath is configured to deliver the anchor, plug, and/or filament to the tissue tract and/or vessel opening for deployment; anda device handle coupled to the proximal end of the device sheath, wherein the device handle includes a plunger configured to deploy the anchor, plug, and/or filament into the tissue tract and/or opening in the vessel wall, wherein the device handle includes a plunger protection mechanism to prevent premature compression of the plug;wherein the filament is coupled to at least one of the device sheath or the device handle; andwherein the plunger protection mechanism includes a clip and a pin, the clip having a first end coupled to the plunger and a second end configured to releasably engage the pin, wherein the pin is secured relative to the device handle, wherein when the clip is engaged to the pin, the plunger is in a depressed position to prevent premature deployment of the anchor, plug, and filament, wherein when the clip is disengaged from the pin, the plunger is in a second non-depressed position.
