Identification ring for catheter
First Claim
1. A catheter assembly having a distal end adapted for insertion into a living body and a proximal end adapted to remain external to said body,said assembly including a surface for placement of marking indicia,a plurality of marking indicia each indicating one of a plurality of locations within the living body at which said distal end may be placed during insertion, said markings being positioned at spaced intervals on said surface, anda member located on said assembly for movement on said surface,said member being provided with at least one window adapted to be moved into alignment with a selected one of said markings so that said selected marking is visible through said window.

Abstract
A catheter assembly which has a distal end adapted for insertion into a living body and a proximal end adapted to remain external to said body or a cable for use in such an assembly includes a cylindrical surface on which are inscribed a plurality of markings. Each of the markings indicates one of the specific locations within the living body at which the distal end may be placed during insertion. The markings are positioned at spaced intervals around the circumference of the cylindrical surface. A sleeve is rotatably and/or axially movable around the cylindrical surface, the sleeve being provided with at least one window adapted to be moved into alignment with a selected one of the markings.
