Syringe filling device for fat transfer
The present disclosure provides systems and methods for transfer of tissue or other materials such as adipose tissue. The systems and methods can include a vessel and a syringe to facilitate transfer of tissue between one or more vessels and tissue implantation devices.
1. A tissue transfer system, comprising:
a material holding or processing vessel, including:
an exterior wall surrounding an interior vessel volume for holding tissue;
an outlet in fluid communication with the interior vessel volume; and
an exterior fluid passage having an opening disposed proximate an opening of the outlet;
a syringe, including:
a syringe body having an interior syringe volume; and
a syringe tip comprising a peripheral wall having a distal opening forming a first passage in fluid communication with the interior vessel volume, wherein the syringe tip is adapted to be mated with the outlet of the material holding or processing vessel such that the opening of the outlet is in fluid communication with the first passage of the syringe tip and the exterior fluid passage of the material holding or processing vessel is in fluid communication with the interior syringe volume of the syringe body; and
wherein application of negative pressure at the exterior fluid passage draws tissue through the outlet and into the interior syringe volume.
2. The system of claim 1 , wherein the material holding or processing vessel further comprises an elongated lumen extending from the exterior wall to the outlet.
3. The system of claim 1 , wherein the material holding or processing vessel further comprises a ridge whose interior surface is configured to mate with an exterior lateral surface of the syringe tip.
4. The system of claim 1 , wherein the material holding or processing vessel comprises a mating surface that connects with an end of the syringe tip.
5. The system of claim 1 , wherein a distal end of the exterior fluid passage comprises an adapter to facilitate connection to a source of negative pressure.
6. The system of claim 1 , wherein the syringe further comprises a plunger adapted to move longitudinally within the syringe body.
7. The system of claim 6 , wherein the syringe further comprises a locking mechanism for securing the plunger in a selected longitudinal position.
8. The system of claim 1 , wherein the exterior fluid passage has a proximal opening, a lumen, and a distal opening, wherein the proximal opening, lumen, and distal opening are external to the interior vessel volume, and the distal opening is located proximate an opening of the outlet.
9. The system of claim 1 , wherein the material holding or processing vessel further comprises at least one mixing blade, filter, fluid inlet, or fluid outlet to facilitate tissue washing or treatment.
10. The system of claim 1 , wherein the vessel comprises a plurality of outlets and a plurality of exterior fluid passages to allow the vessel to mate with multiple syringes.
11. The system of claim 1 , wherein the syringe tip further comprises a second passage through the peripheral wall in fluid communication with the interior syringe volume of the syringe body and the exterior fluid passage of the vessel.
12. A tissue transfer vessel, comprising:
an exterior wall surrounding an interior volume for holding a tissue;
an elongated lumen extending from the exterior wall to an outlet;
an exterior fluid passage having a proximal opening, a lumen, and a distal opening, wherein the proximal opening, lumen, and distal opening are external to the interior volume, and the distal opening is located proximate an opening of the outlet, the lumen of the exterior fluid passage at least partly embedded within the exterior wall; and
a ridge surrounding the elongated lumen whose interior surface is configured to mate with an exterior lateral surface of a syringe tip.
13. The vessel of claim 12 , wherein a portion of the exterior wall surrounding the elongated lumen outlet comprises a mating surface that connects with an end of a syringe tip.
14. The vessel of claim 12 , wherein the tissue transfer vessel further comprises at least one mixing blade, filter, fluid inlet, or fluid outlet to facilitate tissue washing or treatment.
