Abstract
Abstract Guide catheter unibody and method for manufacturing such a catheter. In one preferred embodiment, the present invention is a unibody guide catheter for use in percutaneous transluminal angioplasty procedures. The catheter includes a base layer and a structural layer formed over the base layer. The structural layer includes strands which cross at a plurality of points, the strands being attached together for structural integrity at a substantial number of points where they cross. The structural layer may be at least partially embedded in the base layer. Additionally, a cover layer is formed over the structural layer.
