Manipulatable delivery catheter for occlusive devices
First Claim
1. A catheter section comprising:
- a.) a balloon region having a main lumen and an inflatable member within said balloon region, b.) a flexible joint region within said balloon region, and c.) a push/pull wire having a distal end secured to a radio-opaque band fixed to the catheter section, wherein the wire is configured to be pushed and pulled along a longitudinal axis of the wire through a wire lumen having an open distal end and adjacent to the main lumen to flex the flexible joint region.

Abstract
This is in the general field of surgical instruments and is, specifically, a microballoon-tipped delivery catheter with a flexible, proximally-manipulated hinge or joint region. The catheter may have a shaft of varying flexibility which contains several lumen. The inner, or delivery, lumen generally may be used with a guide wire to access target sites within the body via the flexible, small diameter vessels of the body. The delivery lumen may be also used for placement of occlusive materials, e.g., in an aneurysm. Inflation of the micro-balloon, located near the distal tip of the catheter, is effected using the inflation lumen. The push/pull wire lumen contains a wire, which when manipulated, flexes the catheter'"'"'s distal tip.

25. A catheter assembly for delivering a vaso-occlusive member comprising:
-
a.) an inner tubing member having a lumen and extending between a proximal and a distal end of the catheter;
b.) a guidewire insertable through and removable from said inner tubing lumen and which guidewire is suitable for guiding the catheter when the catheter is advanced through a hollow body organ;
c.) an inflation member in fluid communication with an inflation lumen defined in the catheter;
d.) a push/pull wire attached within the catheter, wherein the push/pull wire is adapted to be pushed and pulled along a longitudinal axis of the wire through a wire lumen having an open distal end and adjacent to the lumen of the inner tubing member; and
e.) a flexible joint region defined along the catheter which is manipulatable via pushing and/or pulling the wire. - View Dependent Claims (26, 27, 28, 29)
