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.
