Abstract

A device is provided for introducing into a patient a combination of adipose tissue and an additive, for example, a hydrogel additive. The device includes a fat cartridge, an additive cartridge containing an additive, and a housing configured to receive, in a side-by-side manner, the fat cartridge and additive cartridge. A mixing tip may be included for causing mixing of the cartridge components prior to extrusion from a needle or cannula.

Claims

1. A device for introducing into a target region of a patient, a combination of adipose tissue and an additive, the device comprising:

a fat cartridge;

an additive cartridge;

a housing configured to receive, in a side-by-side manner, the fat cartridge and additive cartridge;

a mixing tip on the housing, the mixing tip including a distal end for receiving a cannula or needle;

a plunger assembly slidably received in the fat cartridge and the additive cartridge, the assembly including a fat cartridge plunger rod and an additive cartridge plunger rod;

a thumb piece structured to fix the fat cartridge plunger rod and the additive cartridge plunger rod in place, in variable positions, with respect to each other; and

a valve structured to prevent extrusion of additive from the additive cartridge without extrusion of fat from the fat cartridge.

2. The device of claim 1 wherein the thumb piece is structured to be snapped onto the fat cartridge plunger rod.

3. The device of claim 1 wherein the housing is configured to receive the fat cartridge and the additive cartridge in a longitudinally slidable manner.

4. The device of claim 1 wherein the housing is configured to receive the fat cartridge and the additive cartridge in a lateral manner.

5. The device of claim 1 wherein the additive cartridge contains an additive.

6. The device of claim 5 wherein the additive comprises hyaluronic acid and collagen.

7. The device of claim 5 wherein the additive comprises hyaluronic acid crosslinked with collagen.

8. A device for introducing into a target region of a patient, a combination of adipose tissue and an additive, the device comprising:

a fat cartridge;

an additive cartridge including an additive;

a housing configured to receive, in a side-by-side manner, the fat cartridge and additive cartridge;

a mixing tip on the housing, the mixing tip including a distal end for receiving a cannula or needle;

a plunger assembly slidably received in the fat cartridge and the additive cartridge, the assembly including a fat cartridge plunger rod and an additive cartridge plunger rod;

a thumb piece structured to fix the fat cartridge plunger rod and the additive cartridge plunger rod in place, in variable positions, with respect to each other; and

a valve structured to prevent extrusion of additive from the additive cartridge without coextrusion of fat from the fat cartridge.

9. The device of claim 8 wherein the additive comprises hyaluronic acid crosslinked with collagen.
