Abstract

An axially-compressible coil carrier comprising first and second parallel, coaxial end rings, a plurality of carrier rings positioned between the first and second end rings, and a plurality of support struts arranged in rings, the rings of struts alternating with the carrier rings, and neighboring carrier rings being joined to each other by one of the rings of support struts. The carrier rings are parallel to and coaxial with each other and with the first and second end rings, and are separated by an inside distance of between about 5 mm and about 12 mm. The struts in each of the rings are divided into first and second groups. The struts in the first group are spaced equidistantly around the circumference, and are alternated with pairs of struts of the second group. The struts of the second group are generally parallel to their neighboring struts of the first group to form triads of parallel struts, the struts in each the triad being equidistantly spaced. The junctions of the outer surfaces and the side faces of the struts of the first group are uniformly inclined at an angle .alpha. of between about 11.degree. to about 30.degree. to a line on the outer cylindrical surface parallel…
