1. A medical device configured for introducing a blind rivet through soft tissue, the device comprising:
- a rivet introduction device comprising;
an elongate outer sheath having an outer sheath lumen extending therethrough;
an elongate inner sheath having an inner sheath lumen extending therethrough; and
an elongate mandrel having a wire guide lumen extending therethrough;
wherein the elongate inner sheath is disposed in a longitudinally slidable manner through at least a portion of the outer sheath lumen and the elongate mandrel is disposed in a longitudinally slidable manner through at least a portion of the inner sheath lumen;
wherein a distal end portion of the elongate mandrel includes flexible structure configured to allow radial expansion/contraction; and
a rivet disposed coaxially around the elongate mandrel adjacent the distal end portion of the elongate mandrel.
