Abstract
An elastic, biodegradable plug has a proximal retainer and a distal retainer coupled by a waist. The plug may be positioned to straddle a wound in a blood vessel wall of a patient and therefore close the wound to stop bleeding through the wound. To position the plug in the wound, an operator may insert the plug into a sleeve extending through the vessel wall into the vessel and move the plug through the sleeve with a positioning tool. In the sleeve, the distal and proximal retainers of the plug are compressed. As the distal retainer of the plug exits the distal end of the sleeve into the vessel, the distal retainer expands in the vessel such that a surface of the distal retainer faces an inner side of the vessel wall. The positioning tool and the sleeve are then removed to position the waist in the wound of the vessel wall and allow the proximal retainer to expand such that a surface of the proximal retainer faces an outer side of the vessel wall.
