A portable apparatus useful for collection and processing of human biological material, such as adipose or cancellous bone material, to prepare a concentrated product (e.g., stromal vascular fraction). The apparatus has a container with a containment volume with a tissue retention volume and a filtrate volume separated by a filter and with a pellet well for collecting concentrate product in the form of a pellet phase from centrifuge processing. The pellet well is accessible only from above when the apparatus is in an access orientation. Collected pellet phase material may be removed from the pellet well by direct aspiration, without suspending the material in a suspension liquid within the container. Access ports may be configured for access only from above the container. The apparatus may include a tissue collector disposed in the disuse retention volume to engage and collect collagen or other stringy tissue. A method of processing adipose tissue to concentrate leuko stromal vascular cells includes multi-step processing using a portable container.

Disclosed herein are kits of consumable parts for a closed-loop adipose transplant system, closed-loop adipose transplant systems, controllers therefor, and methods of use thereof.

A method of treating soft tissue conditions. A harvesting device is provided. The harvesting device is operably connected to a tissue processing device using tubing. An aperture is formed in a bone. The bone has an interior. The harvesting device is inserted through the aperture in the bone and into the interior of the bone. The harvesting device is manipulated to dissociate connective tissue progenitor cells in the interior of the bone. Tissue is aspirated from the interior of the bone. The connective tissue progenitor cells are separated from the aspirated tissue. The separated connective tissue progenitor cells are injected in a region of a body that is experiencing a soft tissue condition to treat the soft tissue condition.

An adipose tissue (AT) transfer system includes, on the aspiration side, an aspiration cannula, an aspiration pump, a container, and flexible tubing connecting the aspiration cannula to the container. On the reinjection side, the system includes a reinjection cannula, flexible tubing connecting the inlet of the reinjection cannula to the container, and a reinjection pump imposing positive-displacement pumping action on the flexible tubing and causing movement of AT in a pulsed mode. The aspiration pump operates to continually supply harvested AT to the second flexible tubing while the reinjection pumps causes continuous or pulsed deposition of the AT at injection site. To ensure that internal pressure and/or flow of the AT through a channel of delivery of the AT to the reinjection site does not exceed a predetermined value, the system contains an external pressure sensor configured to measure such internal pressure in absence of a part that is in direct contact with the AT.

A device for filtration of fat extracted during liposuction procedures. The device includes: a first reservoir filled with a physiological solution adapted to be suctioned by a syringe containing fat mixed with blood and anesthetic; a second reservoir, empty, intended to receive cyclically from the syringe a liquid mixture consisting of the suctioned solution, blood and anesthetic separated from the fat; and at least one filter element provided with a connection member for connection of the syringe, the filter element being connected to the first reservoir and the second reservoir through a three-way connector. A first one-way valve configured to allow passage of a flow of fluid from the first reservoir towards the connector is arranged on a branch of the connector connected to the first reservoir. A second one-way valve configured to allow passage of a flow of fluid from the connector towards the second reservoir is arranged on a branch of the connector connected to the second reservoir.

A closed system for harvesting fat through liposuction, concentrating the aspirate so obtained, and then re-injecting the concentrated fat into a patient comprises as its main components a low pressure cannula having between about 7 to 12 side holes of about 1-2 mm by 2.0 to 4.0 mm, a spring loaded syringe holder with a constant force or coiled ribbon spring to apply a substantially constant pressure over the fill excursion of the plunger, and a preferably flexible collection bag which is also preferably graduated, cylindrical over most of its body and funnel shaped at its bottom, all of which are connected through flexible tubings to a multi-port valve. The multi-port valve has two flutter/duck bill valves which restrict the fluid flow to a one way direction which effectively allows the syringe to be used to pump fat out of a patient and into a collection bag in a continuous manner. After the bags are centrifuged to concentrate the fat, the excess fluids are separated and the valve is re-connected to permit the syringe pump to reverse fluid flow to graft the concentrated fat back into the patient.

The present disclosure provides an inventive method of treating deteriorated skin tissue in the face or selected areas of the body, wherein the skin tissue has deteriorated due to aging and/or other factors, by injecting mesenchymal stem cells (MSCs) into these areas, resulting in improving and/or restoring the affected areas. In one aspect, the MSCs are obtained autogenously. In another aspect, the MSCs are minimally manipulated. In yet another aspect, treatment of the skin tissue is carried out using bone marrow concentrate that contains the MSCs. A platelet rich plasma (PRP) may be added to a bone marrow concentrate containing MSCs.

A device that allows for either fat graft preparation or cell fraction harvest is disclosed. The device includes a first centrifuge tube configured to receive and process a biological substance, the first centrifuge tube comprising an upper cylindrical portion and a lower conical portion, a sterile tissue inlet fitting, at least one sterile processing fluid inlet fitting, a sterile suction fitting, and at least one sterile extraction port connected to a first extraction tube. The first centrifuge tube further includes an internal space including a screen being positioned therein, the screen being configured to divide the internal space in half, and a filter positioned therein, the filter being positioned below the screen in the lower conical portion of the first centrifuge tube. The device may further include a second centrifuge tube configured to receive and further process the biological substance from the first centrifuge tube. The second centrifuge tube has at least one sterile fitting, wherein the second centrifuge tube is releasably connected via the at least one sterile fitting to one of the at least one sterile extraction ports of the first centrifuge tube.

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 including an available processing volume in a range of from 75 cubic centimeters to 1300 cubic centimeters, and 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 a mixing device for mixing contents within the tissue retention volume, and including a rotatable shaft extending from outside of the internal containment volume to inside of the internal containment volume and comprises at least one mixing member that is disposed in the tissue retention volume and is connected with the shaft to move through the tissue retention volume relative to the filter when the shaft is rotated. Methods include use of the apparatus to process human biological material containing adipose, such as to prepare a stromal vascular fraction concentrate product or a fat graft composition.
