Abstract:
1. A device for at least partly liquefying a tissue, comprising: a reservoir; an abrasive material operatively coupled to the reservoir, the reservoir being configured to transmit mechanical energy through the abrasive material to the tissue in the form of stirring, abrasion, pressure, or shear force; and a liquefaction promoting medium, the liquefaction promoting medium comprising a non-ionic surfactant and a zwitterionic surfactant, the zwitterionic surfactant comprising one or more of: 3-(decyl dimethyl ammonio) propane sulfonate, 3-(dodecyl dimethyl ammonio) propane sulfonate, myristyldimethyl ammonio propane sulfonate, hexadecyldimethyl ammonio propane sulfonate, cocamidopropyl betaine, oleyl betaine, cocamidopropyl hydroxysultaine, or 3-(3-cholamidopropyl)-dimethylammonio-1-propanesulfonate, and the reservoir being configured to be operatively connected to the tissue and to apply the liquefaction promoting medium to the tissue.
