The insertion vessel sheath of the flexibiility where deyurometa changes

摘要

Solutions Resistance twist the characteristic insertion vessel sheath (10) is with flexibiility. The insertion vessel sheath includes, the inside liner (31) with, the coil (33) with, the outer part tube (20). The inside liner includes, penetrating to longitudinal direction, the hole where it extends (30) it is possible to advance the catheter, through this hole. The coil (33), it was arranged in longitudinal direction, the inside liner (31) we have possessed the plural winding being compressed and being installed the around, winding is arranged, specified interval can be less crowded. The outer part tube (20), the coil (33) with the inside liner (31) the around we are arranged in longitudinal direction, we are connected to the inside liner through the gap during winding. As for difference of diameter between the inside liner and the catheter, from approximately 0.0005 approximately 0.004 inches (from 0.013 approximately 0.10mm) it is inside the range.
