Abstract

An intraluminal catheter having an expandable tubular open-walled element for immobilizing at least part of the catheter within a patient'"'"'s body lumen, generally comprising an elongated shaft and a tubular open-walled element secured to the shaft, wherein the tubular open-walled element is at least in part expandable from an unexpanded diameter to a larger diameter expanded diameter within the body lumen. The expanded diameter configuration is configured to contact a wall defining the body lumen and thereby releasably secure at least part of the catheter within the body lumen. A cannula member, used for delivering or removing fluids from the body lumen, can be positioned in one or more optimal perfusion locations within the body lumen during use, independent of the secured site. When occlusion of the axial flow is necessary, an optional occluding member may be reversibly deployed so that it expands inside and against the expanded tubular open-walled element . The optimal occlusion site can also be chosen independently of the secured site.
