Fixation Methods for Miniature Medical Devices in Tubular Structures

摘要

A method and system of traversing a device through an accommodating conduit to reach a target area within the accommodating conduit can include varying an amount of elasticity of the device or an amount of torsion moment of the device applied to the accommodating conduit or varying both to minimize bending forces as the device traverses the accommodating conduit. The method or system upon reaching the target area within the accommodating conduit, can further include varying the elasticity or the torsion moment of the device or varying both to cause the device to stiffen. Other embodiments are disclosed.

1. A method of traversing a device through an accommodating conduit to reach a target area within the accommodating conduit, comprising:
varying an amount of elasticity of the device or an amount of torsion moment of the device applied to the accommodating conduit or varying both to minimize bending forces as the device traverses the accommodating conduit; upon reaching the target area within the accommodating conduit, further varying the elasticity or the torsion moment of the device or varying both to cause the device to stiffen.
