## Abstract

Apparatuses and methods for recovering solid tissue and dislodged cells (“D-cells”) from a biopsy are disclosed herein. In an embodiment, a biopsy container apparatus includes a sample collection container, a basket sieve, and a buffer container. The sample collection container includes a reagent chamber. The basket sieve is configured for removable attachment at least partially within the sample collection container and includes a sieve surface configured to pass the D-cells from the biopsy but not the solid tissue from the biopsy. The buffer container is configured for removable attachment to the sample collection container and includes a buffer chamber.

## Claims

### Claim 1

A biopsy container apparatus for recovering solid tissue and dislodged cells (“D-cells”) from a biopsy, the biopsy container apparatus comprising:
a sample collection container including a reagent chamber;
a basket sieve configured for removable attachment at least partially within the sample collection container, the basket sieve including a sieve surface configured to pass the D-cells from the biopsy but not the solid tissue from the biopsy; and
a removable container configured for removable attachment to the sample collection container, the removable container including a chamber.

### Claim 2 (depends on 1)

The biopsy container apparatus of claim 1, wherein
the removable container includes a funnel portion configured to guide the solid tissue and the D-cells from the biopsy into the buffer chamber.

### Claim 3 (depends on 2)

The biopsy container apparatus of claim 2, wherein
the removable container is configured for attachment to the sample collection container with the chamber at least partly located within the sample collection container, and with the funnel portion at least partly located outside of the sample collection container.

### Claim 4 (depends on 1)

The biopsy container apparatus of claim 1, wherein
the sample collection container includes a rim configured to suspend the basket sieve within the sample collection container above the reagent chamber.

### Claim 5 (depends on 1)

The biopsy container apparatus of claim 1, wherein
the removable container includes an inner surface with a first attachment mechanism,
the sample collection container includes an outer surface with a second attachment mechanism, and
the removable container is removably attached to the sample collection container by cooperation between the first attachment mechanism and the second attachment mechanism.

### Claim 6 (depends on 5)

The biopsy container apparatus of claim 5, wherein
the first attachment mechanism and the second attachment mechanism include corresponding threads enabling the removable container to be screwed onto the sample collection container.

### Claim 7 (depends on 1)

The biopsy container apparatus of claim 1, comprising
a lid that fits both the sample collection container and the removable container.

### Claim 8 (depends on 1)

The biopsy container apparatus of claim 1, wherein
the sample collection container is pre-filled with a reagent in the reagent chamber, and
the buffer container is pre-filled with a solution in the chamber.

### Claim 9 (depends on 8)

The biopsy container apparatus of claim 8, wherein
the sample collection container includes between 1 and 2 mL of reagent, and
the removable container includes between 1 and 2 mL of solution.

### Claim 10 (depends on 8)

The biopsy container apparatus of claim 8, wherein
the sample collection container includes a first amount of reagent, and
the removable container includes a second amount of solution that is approximately equal in volume to the first amount of reagent.

### Claim 11 (depends on 8)

The biopsy container apparatus of claim 8, wherein
the solution includes a saline solution.

### Claim 12 (depends on 1)

The biopsy container apparatus of claim 1, wherein
the removable container includes a skirt configured to removably attach the removable container to the sample collection container.

### Claim 13

A biopsy container apparatus for recovering solid tissue and dislodged cells (“D-cells”) from a biopsy, the biopsy container apparatus comprising:
a sample collection container including a reagent;
a basket sieve configured for removable attachment at least partially within the sample collection container, the basket sieve including a sieve surface configured to pass the D-cells from the biopsy but not the solid tissue from the biopsy; and
a removable container configured for removable attachment to the sample collection container, the removable container including a solution.

### Claim 14 (depends on 13)

The biopsy container apparatus of claim 13, wherein
the basket sieve is located between the removable container and the sample collection container when the chamber is attached to the sample collection container.

### Claim 15

A method of recovering solid tissue and dislodged cells (“D-cells”) from a biopsy using a biopsy container apparatus including a removable container, a basket sieve and a sample collection container, the method comprising:
depositing the solid tissue and the D-cells from the biopsy into a solution within the removable container;
removing the removable container from the basket sieve and the sample collection container;
pouring the solid tissue, the D-cells and the solution into the basket sieve while the basket sieve is located within the sample collection container;
removing the basket sieve with the solid tissue from the sample collection container;
placing the basket sieve with the solid tissue into a sealed container for tissue processing; and
sealing a mixture including the D-cells, the solution and the reagent for diagnostic testing.

### Claim 16 (depends on 15)

The method of claim 15, comprising
depositing the solid tissue and the D-cells from a core needle into the chamber.

### Claim 17 (depends on 15)

The method of claim 15, wherein
sealing a mixture including the D-cells, the solution and the reagent includes sealing the mixture within the sample collection container.

### Claim 18 (depends on 15)

The method of claim 15, comprising
receiving the biopsy container apparatus with the removable container, the basket sieve and the sample collection container attached together.

### Claim 19 (depends on 18)

The method of claim 18, comprising
receiving the biopsy container apparatus with the sample collection container pre-filled with a reagent, the basket sieve located at least partially within the sample collection container, and the removable container pre-filled with a solution and located at least partially within the sample collection container.

### Claim 20 (depends on 15)

The method of claim 15, comprising
removing a lid from the removable container before depositing the solid tissue and the D-cells from the biopsy into the removable container, and
wherein sealing the mixture including the D-cells, the solution and the reagent for diagnostic testing includes sealing the D-cells, the solution and the reagent within the sample collection container using the lid.
