ABSTRACT:
An inflatable percutaneous oxygenator has an inflatable balloon suitable for insertion into a blood vessel. Oxygen is circulated through a number of gas-permeable passageways (such as hollow gas-permeable fibers) adjacent to the balloon surface to permit diffusion of oxygen and carbon dioxide between the blood vessel and the passageways. A pump is used to alternately expand and contract the balloon. This causes movement of the passageways within the blood vessel to minimize streaming or channeling of the blood flow around the oxygenator, maximizes turbulence in the blood stream, and therefore maximizes diffusion of gases. An external connector has lumens that supply a flow of oxygen to the passageways, exhaust gas from the passageways, and allow inflation and deflation of the balloon by the pump.
