Abstract: Intravascular imaging devices and methods for making and using intravascular imaging devices are disclosed. An example intravascular imaging device may include a catheter shaft configured to be disposed within a blood vessel. The catheter shaft may have an imaging window region and an imaging lumen. The imaging lumen may be configured to accommodate and imaging assembly therein. A distal tip member may be coupled to the catheter shaft. The distal tip member may have a guidewire lumen formed therein. The imaging window region and the distal tip member may axially overlap.

Abstract: An ultrasound catheter includes a distal port and a proximal port and is adapted to provide fluid communication between the distal port and the proximal port. The ultrasound catheter includes an ultrasound transducer. The ultrasound catheter may be advanced through a guide catheter that is positioned within a patient's vasculature and is fluidly coupled with the patient's blood. A vacuum may be applied to the proximal port, causing the patient's blood to be slowly pulled into the ultrasound catheter through the distal port such that any air near the ultrasound transducer is replaced with the patient's blood and the ultrasound transducer is surrounded by the patient's blood, which is an optimal imaging medium. The ultrasound transducer may be operated to obtain ultrasound images while applying the vacuum to the proximal port.

Abstract: Telescoping catheters for selectively moving a component of a medical device system are disclosed. An illustrative telescoping catheter may comprise a proximal hub adjacent a proximal end of the catheter, a drive cable, and a telescoping section extending from a proximal end adjacent the proximal hub to a distal end. The telescoping section may comprise an intermediate sheath having a proximal end coupled to the proximal hub and extending distally to a distal end, an outer sheath disposed over the intermediate sheath, the outer sheath having a proximal end and a distal end, an inner sheath disposed within the intermediate sheath, the inner sheath having a proximal end and a distal end, and a seal member disposed between the intermediate sheath and an outer surface of the inner sheath. The intermediate sheath may be configured to be longitudinally displaced relative to the inner and outer sheaths.
