Outline of Final Research Achievements

In the present study, a novel flexible mechanism for small medical applications including capsule endoscope, active microcatheter and steerable needle was defined and developed. Console software for MRI scanner and endoscope was also developed. The flexible mechanism developed consists of a flexible sheath and loop-shaped flexible arm independent form the sheath. The arm was just inserted into the sheath and then a distal end was pushed and pulled to be able to bend the sheath repeatedly. As medical applications, 1.7 Fr. active microcatheter and a steerable needle were developed and assessed the feasibilities on animal studies and phantom studies. The console software was developed by using free open source medical imaging software, 3D Slicer with a few functional modules developed originally in the present study. The feasibility of the software was also assessed by using animal study.
