Tissue processing apparatus with fluid suction features and methods relating to collecting and processing human biological material
First Claim
1. An apparatus for collection of human biological material and post-collection processing of collected material, the apparatus being orientable in a collection orientation for collection of human biological material, as oriented in the collection orientation the apparatus comprising:
- a filter;
a container having an internal containment volume, the internal containment volume comprising;
a tissue retention volume and a filtrate volume separated by the filter;
a collection volume within the filtrate volume, the collection volume having a bottom elevation corresponding to a bottom elevation of the filtrate volume and a top elevation that is lower than the bottom elevation of the tissue retention volume;
a tapered portion that tapers in a downward direction with at least a portion of the tapered portion being located above the collection volume;
an inlet port in fluid communication with the tissue retention volume and configured for introducing human biological material comprising adipose directly into the tissue retention volume;
a suction port in fluid communication with the filtrate volume and providing access to the filtrate volume for suctioning from the filtrate volume components passing through the filter from the tissue retention volume to the filtrate volume; and
wherein;
the suction port is in fluid communication with the tapered portion of the internal containment volume through a conduit providing fluid communication from the suction port to a location within the filtrate volume that is within the tapered portion of the internal containment volume;
the conduit extends through the filtrate volume from adjacent the suction port to the location within the filtrate volume;
the suction port is located above the tapered portion of the internal containment volume and above the collection volume;
the location is within the collection volume;
the container comprises;
a fluid containment shell with an internal cavity portion forming at least a part of the internal containment volume, the internal cavity portion being open to above; and
a lid attached to the shell and disposed to cover from above the internal cavity portion;
the suction port passes through the lid;
the shell comprises an upper portion having a first wall surface portion defining a corresponding upper portion of the internal containment volume, wherein substantially all of the first wall surface portion has an incline relative to horizontal of at least 75°
;
the shell comprises a lower portion located below the upper portion and having a second wall surface portion defining a corresponding lower portion of the internal containment volume, the lower portion comprising a tapered wall surface portion defining the tapered portion of the internal containment volume, substantially all of the tapered wall surface portion having an incline relative to horizontal in a range of from 30°
to 60°
; and
the conduit extends from the suction port through the upper portion of the internal containment volume and into the tapered portion within the lower portion of the internal containment volume.

Abstract
A portable apparatus for collection and processing of human biological material containing adipose, such as extracted during a lipoplasty procedure, is useful for multi-step processing to prepare a concentrated product (e.g., stromal vascular fraction) or a fat graft composition. The apparatus has a container with an internal containment volume with a tissue retention volume and a filtrate volume separated by a filter and with a tapered portion to a collection volume for collecting concentrate product. The apparatus has fluid suction features including a suction port and a conduit providing fluid communication from the suction port to a location within the filtrate volume within a tapered portion of the internal containment volume, and optionally including a second suction port and a second conduit to a different location in the filtrate volume with the second conduit being configured to permit elevation adjustment within the filtrate volume. Methods include use of the fluid suction features during collection of human biological material and/or post collection.
