Steerable medical catheter with bendable encapsulated metal spring tip fused to polymeric shaft

A steerable medical catheter, comprising:

• a polymeric main shaft having first and second ends with a plurality of lumens extending longitudinally therethrough;
• a shaft tip portion comprising a metallic coil spring with a polymeric coating having first and second ends, the first end of the metallic coil spring is fused to the second end of the main shaft, the polymeric coating having an inner portion configured to define a plurality of lumens between the first and second ends of the coil spring which extend through the coil spring, the lumens through the coil spring being aligned with the lumens in the main shaft such that the lumens extend through the catheter, the metallic coil spring being fully encapsulated by the polymeric coating and the second end of the main shaft;
• and
• a first control wire located in one of the lumens having a first end which terminates in proximity to the second end of the coil spring and a second end which extends from the first end of the main shaft.
