Abstract
The claimed invention provides an improved tracking tip for use with a work element in a catheter system having a flexible tubular catheter body. Use of a tracking tip according to the present invention will facilitate advancement of the work element within the catheter body and will substantially eliminate the possibility that the work element will puncture the catheter body. Preferred embodiments will comprise a wire coil and will often include a rounded end member, which may be in the form of a solder ball, at the distal tip of the wire coil. In some embodiments, the rounded end member may be coated with a lubricant or a suitable non-stick material to further improve tracking of the work element within the catheter body.
