Abstract: The invention relates to an implantable medical stent having a low profile for delivery through smaller lumens. The stent is constrained during delivery where the helically wrapped points of a diamond cell structure also include at least one crossed joint of intersecting strands to provide a reduced diameter.

Abstract: A device for ultrasonic imaging, and methods for the use an manufacture thereof, particularly of small coronary vessels. The device comprises an elongate member with a distal end that can be positioned within a small vessel of a patient's body while a proximal end is located outside the body, a transducer located at a distal end of the elongate member and operable to scan the distal coronary vessels with ultrasonic pulses, and a signal processor connected to a proximal end of the elongate member and to the transducer for generating and receiving pulses to and from the transducer. A motor may be also connected to the proximal end of the elongate member for rotating the transducer.
