A long maneuverable device for insertion of subjects into body

摘要

A very narrow (small diameter) device where a long steerable device for insertion into the subject's body can be configured as a steerable catheter and guide wire for use in interventional cardiology and neuroradiology including. Also described are a method of fabricating these devices, a method of using these devices, and a controller for controlling these steerable devices. These steerable devices each have a bendable distal region and a plurality of tendons attached to the distal bendable region and extending from the distal bendable region to a proximal handle region with a plurality of axial translation regions Material. An axial translation region may be disposed along the outer surface of the proximal handle region, and each axial translation region may be coupled to a tendon material for bending the distal region. The axial translation regions may be configured to be elastically coupled to each other and to steer the distal bendable region by translating the tendon material.
