James C Wang, Albert Chin, James B Daigle, Douglas J Daniels, Richard M Demello, John F Hartnett, Robert E Reid, Christopher A Rowland, Charles Warich, Thomas A Svatek: Polymeric implements for torque transmission. Boston Scientific Corporation, Fish & Richardson P C, September 14, 1999: US05951494 (211 worldwide citation)

Implements, particularly medical instruments, formed at least in part of elongated polymer members, exhibit high torque fidelity after processing with tension, heat, and twisting. The processing orients the polymer in generally helical paths so that torque imposed at the proximal end can be transmit ...
