Long nose manipulatable catheter
First Claim
1. A catheter section comprising:
- a catheter body having a proximal end and a distal end, said catheter body including a distal flexible joint region, a main lumen extending through said catheter body and through said flexible joint region, and a wire lumen adjacent to said main lumen and extending through said catheter body and through said flexible joint region, the catheter body defining at least a first region having a first flexibility and a second region having a second flexibility more flexible than the first region, the wire lumen of said flexible joint region having an opening near or at a distal end of the flexible joint region, wherein the flexible joint region has a predetermined length sized to affect a flexure of the flexible joint region;
a push-pull wire configured to be pushed or pulled along a longitudinal axis of the wire through the wire lumen, the distal end of said push-pull wire attached to said distal flexible joint region;
a control in communication with a proximal end of the push-pull wire for manipulating the flexible joint region.

Abstract
The long nose manipulatable catheter includes a main lumen, a wire lumen with a push-pull wire therethrough, and a flexible joint region. The catheter section includes a control including a handle and a wire control member engaging the push-pull wire for manipulating the flexible joint region. The push-pull wire may be tapered, having a proximal portion of a first diameter and a smaller diameter distal portion. A coil may be placed around the smaller diameter to prevent buckling of the smaller diameter portion. A strapping coil may also disposed around the outside of the catheter, and an outer covering may be disposed around the strapping coil. An outer covering of a mesh may also be disposed around the distal tip of the catheter.
