Tissue transplantation method and apparatus
First Claim
1. A device for use in tissue transplantation, comprising:
- a substantially rigid outer chamber defining an interior volume including;
an inlet fitting;
at least a first substantially rigid inner chamber including;
a substantially cylindrical body portion and a substantially cylindrical interior bore;
a plurality of perforations in the body portion;
an inlet at a distal end of the body portion, wherein the inlet is adapted for mating with the inlet fitting of the outer chamber; and
an open proximal end;
an integrated plug unit that includes an outer chamber seal having a first diameter that is received by an end of the outer chamber and an inner chamber seal having a second diameter that is received by an end of the inner chamber, an integrated plug unit fitting operable for interconnection to a vacuum device, and an opening, wherein the integrated plug unit fitting is in communication with the opening, the interior volume of the outer chamber, and an exterior of the inner chamber, and wherein the integrated plug unit fitting and the opening of the integrated plug unit are only in communication with an interior bore and the inlet of the inner chamber through the plurality of perforations in the body portion of the inner chamber.

Abstract
The present invention provides for the transplantation of tissue from a donor site in a body to a recipient site. The device includes an outer chamber having an interior volume in which a perforated inner chamber can be placed. During the aspiration of tissue, a vacuum is formed in the interior volume of the outer chamber, to draw tissue from a cannula into the perforated inner chamber. The perforations are sized such that fat is collected within the inner chamber, while fluids and other materials are drawn through the perforations, away from the collected fat. For reinjection, the inner chamber can be removed from the outer chamber, and a sleeve positioned to cover the perforations and thereby form a syringe body that can be interconnected to a needle and plunger for reinjection of the collected fat.
