## Abstract

An improved tissue specimen trapping device for collecting and separating solid particles and materials from body fluids has a porous separator that rests on a shelf-like annular ledge between upper and lower portions of the tissue collection container. At least one tissue collection basket removably disposed in the tissue collection container above the separator shelf has a porous bottom surface to filter tissue specimens from body fluids and has downward projections to the tissue collection basket above the separator shelf to create a space therebetween.

## Claims

### Claim 1

A collection and separation device for use in combination with a fluid collection container operatively coupled to a suction source to withdraw body fluids and collect tissue specimens from a patient, comprising: a tissue collection container separated into upper and lower portions by a porous separator, said upper portion having a larger diameter than said lower portion, said tissue collection container having a ledge on an interior surface thereof for supporting said porous separator, at least one tissue collection basket having a porous lower surface removably disposed in said upper portion to receive body fluids and tissue specimens from the patient, wherein body fluids and tissue specimens from the patient are received in said at least one tissue collection basket, wherein the tissue specimens are retained in the tissue collection basket for subsequent removal from said tissue collection container and wherein the body fluids are collected in the fluid collection chamber, said at least one tissue collection basket having downward projections to provide distance between the porous lower surface thereof and the porous separator.

### Claim 2 (depends on 1)

The collection and separation device of claim 1, further comprising a tissue collection basket retention means comprising a projection disposed inwardly on an inward facing wall of said at least one tissue collection basket and a cooperating recess on an outward surface of a tubular surface extending through said tissue collection container to selectively retain said at least one tissue collection basket in position within said tissue collection container.

### Claim 3 (depends on 1)

The collection and separation device of claim 1, further comprising a projection disposed inwardly on an inward facing wall of said at least one tissue collection basket and a cooperating recess on an outward surface of a tubular surface extending through said tissue collection container to selectively retain said at least one tissue collection basket in position within said tissue collection container.

### Claim 4 (depends on 1)

The collection and separation device of claim 1, wherein said device is adapted to be coupled to a suction source.

### Claim 5 (depends on 1)

The collection and separation device of claim 1, wherein said suction source is adapted to withdraw body fluids from a patient.

### Claim 6 (depends on 1)

The collection and separation device of claim 1, wherein said device is adapted to be coupled to a fluid collection container.

### Claim 7 (depends on 1)

The collection and separation device of claim 1, further comprising a cover having an inlet port formed therethrough and an outlet port formed therethrough.

### Claim 8 (depends on 7)

The collection and separation device of claim 7, wherein the inlet port is coupled to a tube.

### Claim 9 (depends on 8)

The collection and separation device of claim 8, wherein the tube is adapted to form a passage between the upper portion of the tissue collection container and an endoscope.

### Claim 10 (depends on 7)

The collection and separation device of claim 7, wherein the outlet port is coupled to a tube.

### Claim 11 (depends on 10)

The collection and separation device of claim 10, wherein the tube is adapted to form a passage between the tissue collection container and a fluid collection container.

### Claim 12 (depends on 1)

The collection and separation device of claim 1, further comprising a cover having a tube that extends downward from an inside surface of the cover through the porous separator into the lower portion of the tissue collection container.

### Claim 13 (depends on 1)

The collection and separation device of claim 1, further comprising a basket positioning means.

### Claim 14 (depends on 1)

The collection and separation device of claim 1, further comprising a plurality of cooperating projections and recesses on an inside circumferential wall of the tissue collection container and on an outside arcuate wall of the tissue collection basket.

### Claim 15 (depends on 1)

The collection and separation device of claim 1, further comprising a cover, wherein the cover can be rotated to align a first tube with the tissue collection basket, so as to allow body fluids and tissue from the patient to flow into the tissue collection basket when suction is applied to the tissue collection container.
