Abstract:
An intraluminal catheter, comprising:a) an elongated shaft having a proximal end, a distal end, and a lumen; b) a tubular open-walled element having a proximal end, a distal end, and a lumen, being secured to the shaft, and being at least in part expandable to an expanded diameter within a body lumen to contact a wall defining the body lumen and thereby releasably secure the catheter within the body lumen, the distal end of the expanded tubular open-walled element being located distal to the shaft distal end; and c) an elongated cannula member slidably disposal within the lumen of the shaft, and slidably displaceable within the lumen of the tubular open-walled element and through a distal port in the distal end of the tubular open-walled element, having a single lumen and at least one port in a distal section in fluid communication with the cannula member single lumen, the port providing an opening to an outer surface of the cannula member.
