The invention provides a nested tubing cannula which comprises outer and inner elongate tubular members, each having a proximal end, a distal end, and a lumen therebetween. The inner tubular member is sealed at its distal end and is nested substantially coaxially within the lumen of the outer tubular member, so that the gap between the inner and the outer tubular member defines a second lumen whereas the first lumen is the lumen of the inner tubular member. A tubular sleeve is disposed coaxially between the inner and outer tubular members. A balloon is mounted on a distal region of the outer tubular member and is in communication with the first lumen. The cannula further comprises a port proximal or distal the balloon occluder and is in communication with the second lumen. Methods for making the devices herein are disclosed.
A cannula comprising a substantially rigid elongate tubular member having a proximal end, a distal region, a distal end, and a lumen extending from the proximal end to a perfusion port in the distal region the distal region having a first segment curved from an axis of the proximal tubular member, a second segment distal to the first segment and that curves in a direction opposite from the first segment, and a third segment distal to the second segment and that is substantially linear and lies at approximately a 90-degree angle to the axis of the proximal tubular member.
