Abstract:
Intravascular membrane oxygenator catheter systems and methods are disclosed, along with methods of making and using the same. A catheter system includes a catheter shaft having a wall that extends from a proximal end to a distal end along a longitudinal axis to define a lumen, a plurality of hollow fiber membrane loops each having a proximal portion positioned within the lumen of the catheter shaft and a distal portion extending beyond the lumen of the catheter shaft, the hollow fiber membrane loops are nonporous with solid walls; a pneumatic source in pneumatic communication with the hollow fiber membrane loops. The pneumatic source provides a gas containing oxygen at a pressure sufficient to cause a diffusive flux of the gas containing oxygen from an interior of the hollow fiber membrane loops to a fluid exterior to the hollow fiber membrane loops in a region of interest of a subject.
