A tubular catheter support member comprises a plurality of annular segments stacked along a longitudinal axis of the catheter, and a plurality of beams connecting respective annular segments in the stack, wherein the beams meet the respective annular segments at oblique angles, and wherein the beams collectively form a helix around the longitudinal axis of the catheter.

Balloon catheter and method of manufacture

A single lumen balloon-tipped micro catheter, wherein the distal portion of the shaft is reinforced and extends into the balloon to eliminate abrupt transitions in stiffness in the balloon region. The balloon may be formed of a thermoplastic polyisoprene rubber such as hydrogenated polyisoprene which has superior performance and manufacturing attributes.

Single lumen balloon-tipped micro catheter with reinforced shaft

The present invention relates to a high pressure vascular balloon catheter wherein the walls of the tube attached to the balloon-forming segment are reinforced with a braided ribbon member. The walls of the inner tube that provides the lumen for a guidewire may also be reinforced in the same way. The reinforcement has the dual effect of providing strength against rupture under pressure and prevention of ovalizing or kinking during insertion into tortuous vessels of a vascular system.

Kink-resistant braided catheter with distal side holes

This is a micro-vaso-occlusive device intended generally for occlusion of small arteries located distally in the vasculature. The device is made up of a binder, often radio-opaque, which may be short in length by comparison to the length of the included thrombogenic fibers. The fibers form the other portion of the device. At least one end of the device includes a solid but comparatively soft end typically made of a molten mass of the fibers. The micro device may have multiple binder sections. The fibers may be straight, looped, or tufted.

Soft-ended fibered micro vaso-occlusive devices

This is a catheter section having a number of radially placed holes through the catheter section wall and a catheter assembly including that section. That catheter assembly may be used in accessing and treating a tissue target within the body, typically one which is accessible through the vascular system. Central to the catheter section is the presence of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated in such a way to provide an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The orifices in the section are optimally placed in the interstices between the turns of the braid. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.
