A catheter includes a manifold and a proximal shaft portion coupled to the manifold. A distal shaft portion is coupled to a distal end of the proximal shaft portion and is flexible relative to the proximal shaft portion. A fiber reinforcement layer is disposed about the distal shaft portion.

Flow assisted catheter

Catheter having LCP reinforced distal portion

Catheter having distal fiber braid

The present invention provides a catheter for insertion into the body and having proximal and distal ends, the distal end preceding and the proximal end trailing when said catheter is inserted into the body, said catheter comprising an inner tubular shaft and an outer tubular shaft having a proximal outer tube section and a distal outer tube section, the proximal outer tube section further having proximal and distal ends, the proximal outer tube section comprising a polymer encased tubular braid of stainless steel, the polymer encasement for the braid comprising at least one layer of polyimide, the braid having a weave which increases in pick count from the proximal end to the distal end of the proximal outer tube section.

Dilatation catheter with polymide encased stainless steel braid proximal

An intravascular catheter for providing access to distal vascular sites. The intravascular catheter comprises an elongate shaft with a lumen extending therethrough. The elongate shaft is comprised of a composite construction and has a proximal relatively stiff section, a distal section relatively more flexible than the proximal section, and an intermediate section between the proximal and the distal sections that provides a transition in flexibility between the proximal section and the distal section. The distal section has surface contours that impart flexibility to the distal section. A method for processing a tubular member with surface contours for use in a medical device, such as a catheter or guide wire, is also provided.

Process for making a catheter

Vascular access catheter and methods for manufacture thereof

A dilatation balloon catheter includes a shaft having a proximal outer tube section and a distal outer tube section. The proximal outer tube section is formed from a tubular braid of a stainless steel member, which is encased in polyimide material. The distal outer tube section is a tube made of a polymer material, such as a high density polyethylene.
