Abstract
The present invention relates to a guidewire having a shaped three dimensional guide section. In the preferred embodiment the guide section is helical, and exerts an outward radial force on a lumen the guidewire is constrained in. The outward radial force can be measured or calculated according to methods of the present invention. Also described is a system comprising a guidewire and catheter where the force the catheter exerts on a body lumen can also be calculated. Apparatus and methods of making the guidewire are also disclosed, as well as alternative embodiments of the guidewire.
