Abstract
Abstract A non-deforming deflectable multi-lumen catheter with an outer jacket having a deflectable distal end portion, an eccentric pull wire lumen, coil and shim embedded therein. The deflectable distal portion optionally having one or more transaxial notches in the external surface of the outer jacket. A functional device is disposed within the lumen of an inner tube substantially coaxial with the outer jacket of the catheter. The distal tip of the functional device egressible from the distal tip of the catheter, and upon deflection, automatically aligns with the distal tip of the catheter and functional device.
