Abstract

See full text

The present invention comprises a guidewire having a compressible guide section capable of deflecting a catheter to abut a lumen wall. The compressible guide section exerts an outward radial force while it is at least partially compressed within a lumen. The guide section permits a physician to precisely locate a catheter within a body lumen and adjust a catheter tip orientation to be directed to a particular side of a body lumen. A method is disclosed for properly matching a guidewire and a catheter to operate together in the present invention, along with a force measuring instrument to assist in measuring a catheter's resistance force value. This method and systems of the present invention involve determining the exact force relationship between the compressible guide section and the resistance of the catheter in vitro.
