Abstract

A system in accordance with embodiments of the present invention includes a permeable tissue collection vessel or filter element disposed within a collection container. Collected tissue is deposited within the filter element through an inlet. Fluid that passes through the filter element is withdrawn from the collection canister through an outlet. An access port can be provided in a lid of the collection container to facilitate the removal of collected tissue from the tissue collection vessel.

Claims

1. A tissue harvesting system, comprising:

a collection canister, wherein the collection canister is associated with a first volume, and wherein the collection canister has a first open end and a second closed end;

a lid, wherein the lid is interconnected to and extends across the first open end of the collection canister, the lid having apertures, wherein the apertures include at least a first outlet and an inlet, wherein the first outlet is in communication with the first volume;

a filter element, wherein the filter element is associated with a second volume corresponding at least in part to an interior of the filter element, wherein the filter element is located within the first volume, wherein the inlet opens into the second volume, and wherein the first outlet is in communication with a volume included in the first volume and outside of the second volume;

a waste conduit located within the first volume of the collection canister, wherein a first end of the waste conduit is interconnected to the first outlet at the lid, wherein a second end of the waste conduit is open and is nearer to the closed end than to the open end of the collection canister, and wherein the open second end of the waste conduit places the first outlet in communication with an annular volume within the first volume and outside of the second volume;

a harvest tube interconnected to the inlet; and

a vacuum tube interconnected to the first outlet, wherein, except for the apertures in the lid, the first volume is a closed volume.

2. The system of claim 1, wherein the filter element includes at least a first open end portion, wherein the lid further includes a locating member, wherein the locating member extends into the first volume and at least one of receives the open end portion of the filter element or is received by the open end portion of the filter element.

3. The system of claim 2, wherein the lid further includes a second outlet.

4. The system of claim 3, wherein the locating member defines the perimeter of a first area of the lid that includes the second outlet, and wherein the first outlet is outside of the first area.

5. The system of claim 1, wherein the filter element includes an open end portion that is proximate to the lid and a closed end portion that is opposite the open end portion.

6. The system of claim 1, wherein the filter element includes a permeable material.

7. The system of claim 1, wherein the collection canister further includes a mounting member.

8. The system of claim 7, wherein in operation the mounting member of the collection canister is interconnected to a stand, and wherein the collection canister is positioned such that the inlet is above the second end of the waste conduit.

9. The system of claim 1, further comprising:

an access port formed in the lid, wherein the access port provides access to an interior of the filter element.

10. The system of claim 1, further comprising:

a vacuum source, wherein the vacuum source is interconnected to the waste conduit by the vacuum tube interconnected to the first outlet.

13. The system of claim 1, wherein the second end of the waste conduit is one of serrated and perforated.

11. A tissue harvesting system, comprising:

a collection canister, wherein the collection canister is associated with a first volume, and wherein the collection canister has a first open end and a second closed end;

a lid, wherein the lid is interconnected to and extends across the first open end of the collection canister, the lid having apertures, wherein the apertures include at least a first outlet and an inlet, wherein the first outlet is in communication with the first volume;

a filter element, wherein the filter element is associated with a second volume corresponding at least in part to an interior of the filter element, wherein the filter element is located within the first volume, wherein the inlet opens into the second volume, and wherein the outlet is in communication with a volume included in the first volume and outside of the second volume;

a harvest tube interconnected to the inlet;

a vacuum tube interconnected to the first outlet, wherein, except for the apertures in the lid, the collection canister forms a closed volume;

wherein the filter element includes an open end portion that is proximate to the lid and a closed end portion that is opposite the open end portion, and wherein the first outlet is in communication with an annular volume within the first volume and outside of the second volume;

a waste conduit located within the first volume of the collection canister, wherein a first end of the waste conduit is interconnected to the first outlet at the lid, wherein a second end of the waste conduit is open and extends to the closed end of the collection canister, and wherein the open second end of the waste conduit places the first outlet in communication with the annular volume within the first volume; and

a vacuum source interconnected to the vacuum tube, wherein the vacuum source is in communication with the waste conduit.

12. The system of claim 11, wherein the second end of the waste conduit is one of serrated and perforated.
