Title: CENTERING COILED GUIDE
Abstract:
A device and system for providing a centered lumen within a catheter body. A coiled guide lumen (CGL) is composed of a length of wire forming a plurality of coils about the longitudinal axis of the CGL, the CGL including one or more first sections having a first diameter and one or more sections having a second diameter, the second diameter being greater than the first diameter, and a secondary guide lumen extending through the first sections. The CGL may include at least one pull wire extending through the secondary guide lumen and attached at the distal portion of the catheter body. A band may be coupled to an interior of the catheter body distal portion, each of the pull wires being coupled to the annular band. Alternatively, the system may further include a shim coupled to the band, each of the pulls wire being coupled to the shim.
