may be realized solely within the interior space 41 of the housing 42 and the syringe 70 can be directly coupled to the port 45 to recover the mixture 80 directly from the interior space 41 of the housing 42 further rather than mixing the gel and tissue in a separate container such as container 170 the outlet 46 of the tissue collection device 140 can be plugged or otherwise sealed and the mixture 80 of gel 62 and tissue particles 71 can be realized directly in the tissue collective device 140 moreover although the filtration devices have been described as either disk shaped or basket shaped filters other suitable filtration devices having any number of possible geometric shapes may be employed such examples comprise nucleated cell microfiltration tubular or hollow fiber filtration devices having for example square cylindrical tubular or round geometries in addition any filtration surface that contacts any of the relevant compositions of the tissue fluid or other surgical materials is sterile or can be readily sterilized for the purposes of this disclosure the injectable gel 62 may comprise any suitable biological or synthetic gels for example the gel can comprise hyaluronic acid alginate cross linked alginate collagen fibrin glue fibrin clot poly n isopropulacrylamide agarose.
