Abstract:
A method of forming an appliance implantation assembly from a pair of appliances to be implanted, each said appliance having a front end wire ring, a rear end wire ring arranged facing to said front end wire ring, a tubular cover which connects said front end wire ring and said rear end wire ring, and a plurality of intermediate wire rings spaced apart from each other between the front end wire ring and the rear end wire ring, in which each of the wire rings exhibits flexibly foldable elasticity, and wherein a front end wire ring of one of said appliances, a rear end wire ring of the other appliance, and an intermediate wire ring of said other appliance, adjacent said rear end wire ring of the other appliance, are formed as separate closed loops, said method comprising:inserting said one appliance part-way into the other appliance such that said one appliance extends within said other appliance in overlapping relationship therewith;locating the front end wire ring of said one appliance in contact against an interior surface of the tubular cover of said other appliance, within a space formed between the rear end wire ring of said other appliance and said adjacent intermediate wire ring; andadjusting an axial position of said front end wire ring within said space, to thereby vary an overall length of the appliance implantation assembly.
