Abstract

A long nose manipulatable catheter is described herein. The catheter generally comprises a flexible joint region defining a main lumen and an adjacent wire lumen. The wire lumen has an opening near or at a distal end of the flexible joint region and a push/pull wire can be pushed or pulled through the wire lumen. The catheter assembly may also comprise at least one radio-opaque marker band for securing the push/pull wire. The joint region has a predetermined length sized to affect a flexure of the joint and is generally located at the distal end of the catheter. The joint region itself may be varied to extend distally from where the braid terminates, or it may extend to encompass a portion of the braid. By varying a length of the joint region, the amount of curvature and flexure of the joint region can be controlled.

Claims

1-40. -40. (canceled)

41. A long nose manipulatable catheter section comprising:

a flexible joint region having a distal face, the flexible joint region defining a wire lumen and a main lumen therethrough, and the wire lumen having an opening from the flexible joint region near or at the distal face of the flexible joint region;

the flexible joint region including tubing defining an extension of the main lumen beyond the distal face of the flexible joint region;

the extension containing at least one radio-opaque band; and

a push/pull wire positioned within said wire lumen and configured to be pushed or pulled through the wire lumen, said push/pull wire having a distal portion extending through said opening of said wire lumen beyond the distal face of the flexible joint region, and said distal portion of said push/pull wire being secured to said at least one radio-opaque band.

42. The long nose manipulatable catheter section of claim 41, further comprising a braid disposed along at least a majority of the wire lumen.

43. The long nose manipulatable catheter section of claim 42, wherein said braid terminates proximally of the flexible joint region.

44. The long nose manipulatable catheter section of claim 41 wherein the main lumen further comprises a lining along at least a majority of the main lumen.

45. The long nose manipulatable catheter section of claim 44 wherein the lining of the main lumen comprises a lubricious lining.

46. The long nose manipulatable catheter section of claim 41 wherein the wire lumen further comprises a lining along at least a majority of the wire lumen.

47. The long nose manipulatable catheter section of claim 46 wherein the lining of the wire lumen comprises a lubricious lining.
