Claim:
A medical device for closing a perforation in tissue, the medical device comprising: a tubular member defining a longitudinal axis and having a distal end, an exterior surface and an interior space, the tubular member defining at least one slot extending laterally through the tubular member and extending proximally from the distal end, the slot opening laterally to communicate the interior space with the exterior surface; a carrier element extending along the exterior; an elastic band positioned around the exterior surface of the tubular member and engaged with the carrier element; a staple positioned within the interior space of the tubular member and translatable beyond the distal end of the tubular member, a portion of the staple extending through the slot, the staple including a first prong spaced apart from a second prong, the first prong translatable relative to the second prong, the first and second prongs each including a first end defining a piercing tip structured to pierce tissue; and the carrier element structured to deliver the elastic band beyond the distal end of the tubular member whereupon the elastic band contracts, the elastic band engaging the staple when it contracts to translate the first and second prongs towards each other.
