摘要:
A tubular device including a tubular having a continuous wall and a substantially constant inner radial dimension and an outer surface that varies in radial dimensions configured to lessen a reduction in a longitudinal dimension of the tubular in response to radial expansion of the tubular in comparison to a reduction in the longitudinal dimension of a constantly-dimensioned-inner-and-outer-radially-surfaced-tubular made of a same material as the tubular.
