Narrative:

I was cleared for a visual approach to runway 34. When I checked in on tower they advised of helicopter traffic which was to my right. I reported traffic was not in sight. Tower advised helicopter of my position again. Helicopter reported he had me in sight. My situational awareness placed the helicopter below me and passing beneath me from right to left and it sounded like he would be using the parallel runway 35.I intentionally flew a significantly higher than normal visual approach to pass well above the runway 35 final approach course. Upon joining the runway 34 localizer I began a descent and got one TCAS 'traffic' call and observed a target -300 below me. I pulled up again and the target disappeared about 10 seconds later and I began a descent to try to join the glideslope to stabilize my approach. After selecting full flaps I noticed out of my peripheral vision to the right a helicopter at my altitude less than 100 feet off my right wing. When I looked to the right the helicopter was veering away from me to the right and I initiated a slight turn to the left to make sure I missed him.I asked the tower if he had seen the helicopter I had missed by less than 100 feet on the final approach course and got no response. I made a normal landing and exited and asked what the call sign of the helicopter was so it would get on the tape for review. After landing I called the tower chief and reported the incident so he could begin an immediate investigation into what caused the problem.

My situational awareness placed the helicopter below me and passing beneath me from right to left and it sounded like he would be using the parallel Runway 35.I intentionally flew a significantly higher than normal visual approach to pass well above the Runway 35 final approach course.
