    Abstract: An elongate shaft of a medical catheter including a thermoset polymeric tubular member including a skived distal portion. The skived distal portion includes a distally extending trough having a convex surface and a concave surface. A thermoplastic tubular sleeve may be positioned over at least a portion of the skived distal portion of the thermoset polymeric tubular member. In some instances, the thermoplastic tubular sleeve includes a crescent-shaped tubular portion defining a crescent-shaped lumen. The trough of the skived distal portion may extend through the crescent-shaped lumen. The thermoplastic tubular sleeve is thermally bonded to the inner and outer tubular members of a distal section of the elongate shaft at a guidewire port joint.

    Abstract: A medical device that may be implanted in a patient's body is disclosed. An illustrative medical device has an elongated structure that includes a material loaded with a radiopaque material. The radiopaque material includes radiopaque particles having multiple sets of radiopaque particles. The multiple sets of radiopaque particles may include a first set of radiopaque particles having particles with particle sizes in a first particle size range and a second set of radiopaque particles having particles with particle sizes in a second particle size range. The second set of radiopaque particles may have particles configured to fit within interstitial spaces between particles of the first set of radiopaque particles.

    Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include a guide extension catheter. The guide extension catheter may include a push member having a proximal portion with a proximal stiffness, a distal portion with a distal stiffness different from the proximal stiffness, and a transition portion disposed between the proximal portion and the distal portion. The transition portion may provide a smooth transition between the proximal stiffness and the distal stiffness. The push member may have a first outer diameter. A distal tubular member may be attached to the push member. The distal tubular member may have a second outer diameter larger than the first outer diameter.
