This invention relates to a process for separating a fluid component from a fluid mixture comprising the fluid component, the process comprising: (A) flowing the fluid mixture into a microchannel separator; the microchannel separator comprising a plurality of process microchannels containing a sorpt

This invention relates to a process for separating a fluid component from a fluid mixture comprising the fluid component, the process comprising: (A) flowing the fluid mixture into a microchannel separator; the microchannel separator comprising a plurality of process microchannels containing a sorption medium, a header and a footer, the combined internal volume of the header and the footer being up to about 40% of the internal volume of the process microchannels; the fluid mixture being maintained in the microchannel separator until at least part of the fluid component is sorbed by the sorption medium; purging the microchannel separator to displace non-sorbed parts of the fluid mixture from the microchannel separator; and (B) desorbing the fluid component from the sorption medium and flowing a flush fluid through the microchannel separator to displace the desorbed fluid component from the microchannel separator. The process is suitable for purifying oxygen as well as effecting other fluid separations.

The method of claim 21, wherein during the step of loading the clip, the clip resiliently grips the magazine to provide a frictional resistance to movement of the clip relative to the magazine. 23. The method of claim 22, wherein the magazine has a plurality of resilient clips and the step of advancing the clip includes separately engaging each of a majority of the plurality of clips in the magazine, and separately simultaneously advancing each of the separately engaged clips. 24. The method of claim 21, wherein the step of placing the clip includes placing the clip over a cystic duct. 25. The method of claim 21, wherein the step of loading includes loading a clip having a distal end and an opposite proximal end, the distal end having a height that is less than a height of the proximal end when the clip is in a closed position, the distal end of the clip being loaded first into the magazine. 26. The method of claim 21, wherein the step of loading includes loading a clip having a distal end and an opposite proximal end, the distal end having a transverse width that is greater than a transverse width of the proximal end of the clip, the distal end of the clip being loaded first into the magazine. 27. The method of claim 21, further comprising the step of pre-clamping the tissue before placing the clip over the tissue. 28. A method of ligating tissue of the human body, the method comprising the steps of: loa
