Abstract
An implantable appliance (1) comprises a front end wire ring (2), one or more intermediate wire rings (5) and a rear end wire ring (3) connected by a tubular cover (4). The wire rings (2), (3) and (5) are flexibly foldable. A front end portion (1a) of the appliance (1) is equally divided into four or an even number over four segments with dividing points (6a), (6b), (6c), (6d) between the segments, and a front hooking portion (8) for hauling the appliance (1) is formed at midpoints between the dividing points (6a), (6b), (6c), (6d) and the dividing points (6b), (6c), (6d), (6a). The invention includes a method in which the front end portion (1a) is collapsed into a wavy shape with every other dividing point (6a), (6c) forming forwardly directed peaks and other dividing points (6b), (6d) forming the bottoms of forwardly directed valleys, such that front hooking portions are located between adjacent peaks and valleys.
