Abstract
A method and device are provided for sealing a perforation in the wall of, for example, a blood vessel. The device is in the form of a two part closure which seals the hole by clamping the tissue surrounding the hole from both the inside and the outside of the vessel. In accordance with one exemplary embodiment, two rivet portions are provided which are bayonet or screw threadedly interlocked to clamp the vessel wall about the perforation. An alternate embodiment applies heat to couple the rivet parts as well as to cauterize the wound site. Heat may also advantageously be used to separate the rivet from its delivery system.
