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.
Claims30
A unibody catheter, the catheter being used for percutaneous transluminal angioplasty procedures, the catheter including:
- a. a first layer;
- and
- b. a second layer coupled to the first layer, the second layer including a plurality of strands wherein the strands cross at a plurality of points, and further wherein the strands include means for fixedly attaching the strands to each other at a substantial number of the points where they cross.
A torque control guide catheter having a unibody, the unibody comprising:
- a. a tubular base member;
- b. a reinforcement member at least partially embedded in the tubular base member, the reinforcement member including a plurality of strands which cross at a plurality of points, the strands including means for fixedly attaching the strands together at a substantial number of points where they cross;
- and
- c. a cover layer formed over the tubular base member.
A unibody catheter comprising:
- a. a first layer;
- b. a second layer coupled to the first layer, the second layer including a plurality of strands wherein the strands cross at a plurality of points;
- and
- c. means carried by the strands for attaching the strands together at a substantial number of points where they cross.
A unibody catheter comprising:
- a first layer;
- and
- a second layer, the second layer including a plurality of strands which cross at a plurality of points;
- wherein the strands include a metallic core having a polymeric coating, and further wherein the polymeric coating attaches the strands together at a substantial number of points where they cross.
