Appeal No. 1998-1045 Application 08/482,674 APPENDIX 38. A catheter tip control system comprising: (a) a catheter having a highly flexible, tubular distal catheter section extending from a main catheter tube and having a central axis, catheter wall and describing a distal catheter lumen and having a flexible distal tip area to be precisely maneuvered independent of said main catheter, said control system further comprising: (1) a lateral deflection control element for angularly displacing said distal tip about said central axis threaded within the distal catheter lumen and having a distal end anchored to the catheter wall at or near the distal tip of the distal catheter section in a manner such that the application of rotational torque to the lateral deflection control element produces a corresponding displacement of the distal tip in a plane substantially parallel to the direction of the applied rotational torque when said distal tip is deflected from a linear disposition; and (2) means for applying rotational torque to the lateral deflection control element. 1Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15Last modified: November 3, 2007
