Inflatable percutaneous oxygenator with transverse hollow fibers

摘要

An elongated intravenous percutaneous oxygenator is described having a first and a second set of hollow gas permeable and liquid impermeable fibers, the fibers of each set having an input end and an output end, at least three longitudinally spaced manifolds in communication with one of said input ends or output ends of said fibers, gas delivery means in communication with the input ends of said fibers and gas exhaust means in communication with said output ends and inflatable balloon means disposed longitudinally of said oxygenator so as to be surrounded by said fibers, and gas inflation means in communication with said balloon means for inflating and deflating the balloon means.
