Tissue transfer devices suitable for tissue implementation
Tissue transfer devices suitable for transfer of tissues include a cannula, a plurality of tissue separating members outwardly extendable from the cannula, a tissue reservoir disposed in fluid communication with the cannula and a pump disposed in fluid communication with the tissue reservoir.
System and methods for preparation of adipose-derived stem cells
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.
DEVICE AND METHOD FOR RESIZING ADIPOSE TISSUE FOR IMPLANTATION
A deagglomerator for use in resizing masses of cells is disclosed. The deagglomerator may include a plurality of apertures defined by a plurality of front and back edges. The masses of cells may be passed through the plurality of apertures from the front to the back, and from the back to the front, repeatedly. The deagglomerator may also include a plurality of blades that may aid in the deagglomeration of the cell masses. The deagglomerator may be configured between two syringes so that the tissue may be passed back and forth from the first syringe through the device to the second syringe, and then back again from the second syringe through the device and to the first syringe. In this way, the masses of cells may be properly deagglomerated.

LUER TO LUER TISSUE MORSELIZER
A morselizer has a first end section with an axially and radially hollow luer fitting, a second end section with an axially and radially hollow luer fitting, a housing juxtaposed therebetween, a channel extending axially between the first end section and the second end section and through the housing providing an axial liquid pathway therein, and at least one blade disposed within the housing. Each end of the morselizer is attachable to a structure with a complimentarily sized luer fitting. In an embodiment, the morselizer facilitates atraumatic resizing of material through axial liquid transfer, by transferring material from a first structure attached to the first end section, thence through the channel, where material is resized by the blade, and through the second end section to a second structure attached to the second end section. The resized material may be suitable for injection, such as through a fine needle.
DEVICE FOR HARVESTING, PROCESSING AND TRANSFERRING ADIPOSE TISSUE
The present disclosure provides devices and methods for harvesting and processing tissue from patients for grafting. The devices can include a tissue collection chamber for ascetically collecting, processing, and/or re-implanting adipose tissue.
DEVICE FOR TREATING FAT CELLS TAKEN FROM A PATIENT AND INTENDED FOR A TRANSPLANT
The present invention relates to a device and a method for FIG. 2 treating fat cells taken from a patient and intended for a transplant. More specifically, it relates to a device and a method by suctioning which makes it possible to separate the viable fat cells from the residues and elements which are not transplantable. The device is a device for treating adipose tissues (G) connected to a suctioning means (M), consisting of a sealed treatment chamber (A) comprising a means for connection (17) to said suctioning means (M), a means for inlet (13) of said adipose tissues before treatment, a filtration means (3) and at least one means for outlet (20) of said adipose tissues (G) after treatment, said filtration means (3) comprising a conically shaped external wall (3 1, 3) comprising a narrow base (55) attached to an impeller (25) and an internal sieving means (30) connected to the output means (20), said impeller (25) being subjected to the air pressure reduction created by the suctioning means (M) and constituting a rotary mechanical actuating means for actuating said filtration means (3).
