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.

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 may include a guide catheter. The guide catheter may include an elongate catheter shaft having a proximal end, a distal end, and a central lumen extending therebetween. An inflatable locking member may be disposed within the lumen. The locking member may be configured to longitudinally secure the position of a medical device extending through the lumen relative to the catheter shaft. The guide catheter may also include an inflation lumen in fluid communication with the inflatable locking member.
