Zusammenfassung:Elongate, steerable devices for insertion into a subject's body, including very narrow (small diameter) devices that may be configured as steerable catheters and guidewires for use in interventional cardiology and neuroradiology. Also described are methods of making and using these devices, and controllers for controlling these steerable devices. These steerable devices may have a bendable distal region, a plurality of tendons each 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. The axial translation regions may be arranged along an outer surface of the proximal handle region and each axial translation region may be coupled to a tendon for bending the distal region. The axial translation regions may be elastically connected to each other, and configured to translate the tendon and thereby steer the distal bendable region.
