Abstract
A self-implanting anchor comprising an elongated body having a first portion comprised of a consumable combustible material extending from a leading end of the body and back along the length of the body, and a second portion defining an anchor for implantation in a compact material and which extends from the first portion of the body and back along the length thereof. The elongated body includes a conduit extending axially therethrough and opening at the leading end of the body for supplying an oxidizer through the conduit to the consumable combustible material at the leading end. In use, the leading end portion is positioned against a surface of the compact material and the combustible material is ignited to melt the compact material in a vicinity of the leading end portion of the elongated body. The elongated body is then progressively advanced to progressively melt a portion of the compact material in the vicinity of the leading end portion until the anchor has penetrated the compact material to a certain depth. Combustion is then terminated and the anchor maintained in position at the certain depth until the melted compact material has solidified to secure the anchor in the compact material.
