Abstract

A system for delivering a surgical staple can include various components. The system may include an elongate body with a proximal end, a distal end, and a plurality of delivery platforms disposed adjacent the distal end. A sheath can move relative to the elongate body from a first position in which the distal end of the sheath is disposed distally of a distal-most distal delivery platform to a second position in which the distal end of the sheath is disposed proximally of at least one delivery platform. A plurality of intravascular tacks can be within the system with each disposed about a corresponding delivery platform.
