Abstract
Description
本願は、米国仮特許出願第60/932,413号(2007年5月31日出願)に対する優先権を主張し、その利益を主張する。上記仮特許出願の内容は本明細書において参照することにより援用される。
図12に図示したように、側面から見ると、各リングは完全に円筒形ではなく、前面194と後面196を含む。ここで図16〜17も参照すると、前面194および後面196は、隣接するリングがバネによって接合される点から外側に傾斜し、これにより、遠位部分160の屈曲が可能なV形状の空隙192を形成する。リングの傾斜面によって、隣接するリング間の移動の増加が可能になり、隣接するリングの互いにずれることを予防するずれ止めも提供する。
