Claim:
1. A device for the collection of materials from a medullary bone graft source to be used with a reaming device, the apparatus comprising: a plurality of filters, a plurality of filter containers, and a plurality of connecting tubes, wherein an input of a first stage filter container of the plurality of filter containers containing a first stage filter of the plurality of filters is connected, by a first connecting tube, to an output of the reaming device, the reaming device utilizing an irrigation fluid supply and a suction source, wherein a flow of materials harvested by the reaming device and suspended in the irrigation fluid passes through the first connecting tube, wherein the flow of materials suspended in the irrigation fluid is filtered by the first stage filter, wherein the first stage filter possesses a first particulate size selectivity to separate a first stage retained material from the flow of materials suspended in the irrigation fluid to provide a first stage output flow of materials suspended in the irrigation fluid, wherein the first stage output flow of materials suspended in the irrigation fluid is passed through an output of the first stage filter container, wherein an input of a second stage filter container of the plurality of filter containers is connected, by a second connecting tube, to the output of the first stage filter container, wherein the first stage output flow of materials suspended in the irrigation fluid is filtered by the second stage filter, wherein the second stage filter possess a second particulate size selectivity to separate a second stage retained material from the first stage output flow of materials suspended in the irrigation fluid to provide a second stage output flow of materials suspended in the irrigation fluid, and wherein the second stage particulate size selectivity includes particulate sizes less than those included with the first particulate size selectivity, wherein the second stage filter container includes an evacuation port to permit the flow of materials suspended in the irrigation fluid to be evacuated from the second stage filter container in a continuous process, wherein the continuous process includes the first stage filter container receiving an additional flow of materials suspended in the irrigation fluid from the first connecting tube simultaneously with the second stage filter providing the second stage output flow of materials suspended in the irrigation fluid to the evacuation port of the second stage filter container, wherein the second stage filter comprises a biocompatible filter material which is removable from the second stage filter container, and wherein the second stage filter is configured to receive at least a portion of the first stage retained material in combination with the second stage retained material to create a combined graft product.
