Abstract
Abstract A bone marrow collection kit is provided comprising a collection container for receiving a bone marrow containing fluid having a body that defines an interior and an inlet opening and an outlet opening and including a prefilter that extends from the outlet opening into the interior of the collection container so that fluid must flow through the prefilter to exit the collection container through the outlet opening. A first inline filter member is coupled to the outlet opening of the collection container, the first inline filter member having a flexible plastic body that defines an interior, and an inlet opening and an outlet opening and the interior including a filter so constructed and arranged that fluid that enters the inlet opening must flow through the filter to exit the first inline filter member through the outlet opening. A container for receiving a resultant filtered bone marrow containing fluid having an interior in fluid communication with the outlet opening of the first inline filter member is also provided. Methods for processing the bone marrow and constructing the inline filter are also provided.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
114 words
An inline filter for filtering biological suspensions comprising: a body defined by two flexible sheets of plastic sealed along edges thereof to form an interior having an inlet and an outlet opening; and a filter comprising a screen that is sealed along the edges of the sheets so as to extend across and for an entire length of the interior and divide the interior into a first section and a second section, the screen being so located that the inlet opening is in the first section and the outlet opening is in the second section and fluid entering the interior from the inlet must flow through the screen prior to entering the outlet opening.
Claim 2
Dependent Claim
114 words
An inline filter for filtering biological suspensions comprising: a body defined by two flexible sheets of plastic sealed along edges thereof to form an interior having an inlet and an outlet opening; and a filter comprising a screen that is sealed along the edges of the sheets so as to extend across and for an entire length of the interior and divide the interior into a first section and a second section, the screen being so located that the inlet opening is in the first section and the outlet opening is in the second section and fluid entering the interior from the inlet must flow through the screen prior to entering the outlet opening.
Claim 3
Dependent Claim
15 words
The inline filter of claim 1 wherein the screen is constructed from a fluorocarbon plastic.
Claim 4
Dependent Claim
12 words
The inline filter of claim 1 wherein the plastic comprises polyvinyl chloride.
Claim 5
Dependent Claim
18 words
The inline filter of claim 1 wherein the body and the screens each have a circular cross-sectional shape.
Claim 6
Dependent Claim
18 words
The inline filter of claim 1 wherein the body and the screens each have a square cross-sectional shape.
Claim 7
Dependent Claim
16 words
The inline filter of claim 1 wherein the biological suspension is a bone marrow containing fluid.
Claim 8
Dependent Claim
24 words
The inline filter of claim 1 wherein the two flexible sheets are sufficiently flexible to allow manual manipulation of the filter through the sheets.

Claim 10
Independent Claim
107 words
A method for manufacturing an inline filter comprising the steps of: placing a screen between two sheets of a plastic material; sealing the sheets of plastic together along a resultant seal line having a width to seal edges thereof to create an interior including the screen and to trap a perimeter of the screen within a portion of the width of the resultant seal line between the sheets of plastic so that the screen extends across the entire interior, the screen not extending for the entire width of the resultant seal line; and locating an inlet opening and an outlet opening on opposite sides of the screen.
Claim 11
Independent Claim
107 words
A method for manufacturing an inline filter comprising the steps of: placing a screen between two sheets of a plastic material; sealing the sheets of plastic together along a resultant seal line having a width to seal edges thereof to create an interior including the screen and to trap a perimeter of the screen within a portion of the width of the resultant seal line between the sheets of plastic so that the screen extends across the entire interior, the screen not extending for the entire width of the resultant seal line; and locating an inlet opening and an outlet opening on opposite sides of the screen.
Claim 12
Dependent Claim
14 words
The method of claim 9 wherein the screen is constructed from a fluorocarbon plastic.
Claim 13
Dependent Claim
14 words
The method of claim 9 wherein the plastic sheets are constructed from polyvinyl chloride.
Claim 14
Dependent Claim
12 words
The method of claim 9 wherein the sheets are R/F welded together.
Claim 15
Dependent Claim
15 words
