Title:
COMPRESSION FORCE MEASURING DEVICE OF FLEXIBLE LINEAR BODY
Document Type and Number:
WIPO Patent Application WO/2008/029705
Kind Code:
A1
Abstract:
A measuring device (2) which can detect existence of an obstacle in a pipe from
the outside of the pipe when a linear body inserted into the pipe is operated. The
user-friendly measuring device (2) can measure the compression force in the
direction of longitudinal axis acting on a linear body having a sheath thicker
than the linear body, e.g. a wire provided with a coil for embolization of aneurysm
at the tip, without lowering measurement precision. Miniaturization of the
measuring device (2) can be achieved by minimizing the length of restricting
portions (5, 6). Furthermore, a measuring device (2) which can measure the compression
force in the direction of longitudinal axis acting on a linear body regardless
of the magnitude of buckling load of the linear body can be provided, and it is economical
because the same measuring device (2) is applicable to linear bodies of various
materials.
