摘要： Disclosed is an inter- and intra-catheter flow device for the management of vascular bleeding disorders that provide a liquid flow-pass between proximal and distal balloons for bridging the circulation between the upper and lower segments of a hemorrhaging artery or blood vessel, while blocking the blood flow to the hemorrhaging middle segment(s) of the artery or blood vessel between the two or more balloons. When only one balloon is inflated, these devices can create a pressure gradient between proximal or distal and middle segments of the artery or blood vessel. These devices are useful for controlling proximal artery blood pressure, preventing distal ischemia-reperfusion injury, identifying the bleeding location, controlling the bleeding, repairing and remodeling vascular structures, extending resuscitative endovascular balloon occlusion of the aorta (REBOA) use duration, and performing fluid resuscitation.

摘要： Embodiments of the present invention are directed to a rigid connector which joins an inflation lumen to an inflatable element in a medical device. The connector comprises a shaft fluidly connected to a crossbar. Preferably one embodiment provides a stable junction through which an inflation fluid may pass and inflate an inflatable element which is not co-linear with the axis of inflation. The junction maintains a generally rigid, fixed angle in relation to the axis of the inflation lumen, which in many embodiments is perpendicular to said axis. This fixed orientation creates a robust structure which is resistant to deflection when forces are encountered during its use within tubular and non-tubular structures within the human body. Such a structure maintains a rigid orientation between the inflatable element and the catheter body.
