Abstract
A system comprising: a hollow tube having a distal end, a proximal end, and a lumen extending between the distal end and the proximal end; at least a portion of the tube comprising a porous membrane; and a gas-rich perfluorocarbon solution incorporated in the porous membrane; wherein the porous membrane has a porosity in the range of 0.001-200 microns, in order that: (i) the gas-rich perfluorocarbon solution is effectively incorporated into the porous membrane; and (ii) when the porous membrane is positioned in blood, the gas-rich perfluorocarbon solution elutes out of the porous membrane, in aggregations small enough to prevent the creation of embolisms in the blood, with the elution of the gas-rich perfluorocarbon solution into the blood varying between minutes and several hours, depending on the temperature and the hemodynamics of the blood.
