Abstract
Abstract A fill tool for directing bone replacement material into an expandable bag within a reamed out disc includes a deflector at its distal end which deflects the flow of such material to a one or more side openings at the distal end of the fill tool. This allows the tool to be used without being ejected when filling the bag under pressure and greatly increases the distraction forces possible when filling the bag.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
151 words
A system for filling a bone cavity comprising: a fill container, the fill container comprising a wall the wall defining a fill apace; a predetermined quantity of bone replacement material; and a tool for directing the bone replacement material into the fill space, the tool comprising: a) an elongated hollow tube having a proximal and a distal end, said proximal end being adapted for attachment to a source of the bone replacement material wider pressure; and b) said distal end including at least one deflector opening for deflecting the bone replacement material out of said tube and into the fill space at an angle relative to a longitudinal axis of said tube, each said at least one deflector opening having a length of between about 1 D to 3 D, wherein D is the internal diameter of said tube, the distal end comprising a tip, the tip having a tapered shape.
Claim 2
Independent Claim
151 words
A system for filling a bone cavity comprising: a fill container, the fill container comprising a wall the wall defining a fill apace; a predetermined quantity of bone replacement material; and a tool for directing the bone replacement material into the fill space, the tool comprising: a) an elongated hollow tube having a proximal and a distal end, said proximal end being adapted for attachment to a source of the bone replacement material wider pressure; and b) said distal end including at least one deflector opening for deflecting the bone replacement material out of said tube and into the fill space at an angle relative to a longitudinal axis of said tube, each said at least one deflector opening having a length of between about 1 D to 3 D, wherein D is the internal diameter of said tube, the distal end comprising a tip, the tip having a tapered shape.
Claim 3
Dependent Claim
25 words
The system of claim 1 wherein each said deflector opening includes a deflector for deflecting bone replacement material from said tube through said deflector opening.
Claim 4
Dependent Claim
24 words
The system of claim 2 including two opposing deflector openings and said deflector is a tapered wedge adjacent the distal end of said tube.
Claim 5
Dependent Claim
21 words
The system of claim 2 including a single deflector opening and said deflector presents an angled ramp to said deflector opening.
Claim 6
Dependent Claim
20 words
The system of claim 4 wherein said distal end of said tube is closed or open up to 2 D.
Claim 7
Dependent Claim
36 words
The system of claim 1 where in the wall of the fill container defines a plurality of openings, the plurality of openings being sufficiently small so as to prevent the bone replacement material from passing therethrough.
Claim 8
Dependent Claim
24 words
The system of claim 6 wherein each of the plurality of openings has a nominal diameter of about 0.25 mm to about 5 mm.
Claim 9
Dependent Claim
38 words
The system of claim 6 wherein at least one of the plurality of openings is expandable from the nominal diameter to an enlarged diameter, the enlarged diameter being at least as large as outer diameter of the tube.
Claim 10
Dependent Claim
37 words
The system of claim 1 wherein the fill container comprises a mesh bag, the mesh bag having a plurality of openings therethrough, the plurality of openings sized to retain the bone replacement material within the fill opening.
Claim 11
Dependent Claim
54 words
The system of claim 9 wherein the at least the distal end of the tube and at least one of the plurality of openings are of a complementary size to allow at least a portion of the distal end of the tube to pass through the at least one of the plurality of openings.
Claim 12
Dependent Claim
91 words
A method of filling a bone cavity utilizing the system of claim 1 comprising the steps of: inserting the fill container into a bone cavity; filling at least a portion of the tube with the bone replacement material; inserting at least a portion of the distal end of the tube into the fill space; injecting the bone replacement material out of the at least one deflector opening and into the fill space at the angle relative to the longitudinal axis of said tube; and withdrawing the tube from the fill container.
Claim 13
Dependent Claim
98 words
A tool for directing bone replacement material into a defined space comprising: a) an elongated hollow tube having a proximal and a distal end, said proximal end being adapted for attachment to a source of bone replacement material under pressure; and b) said distal end including at least one deflector opening for deflecting bone replacement material out of said tube at an angle relative to a longitudinal axis of said tube, each said at least one deflector opening having a length of between about 1 D to 3 D, wherein D is the internal diameter of said tube.
Claim 14
Dependent Claim
98 words
A tool for directing bone replacement material into a defined space comprising: a) an elongated hollow tube having a proximal and a distal end, said proximal end being adapted for attachment to a source of bone replacement material under pressure; and b) said distal end including at least one deflector opening for deflecting bone replacement material out of said tube at an angle relative to a longitudinal axis of said tube, each said at least one deflector opening having a length of between about 1 D to 3 D, wherein D is the internal diameter of said tube.
Claim 15
Dependent Claim
25 words
The system of claim 12 wherein each said deflector opening includes a deflector for deflecting bone replacement material from said tube through said deflector opening.
Claim 16
Dependent Claim
24 words
The system of claim 13 including two opposing deflector openings and said deflector is a tapered wedge adjacent the distal end of said tube.
Claim 17
Dependent Claim
21 words
The system of claim 13 including a single deflector opening and said deflector presents an angled ramp to said deflector opening.
Claim 18
Dependent Claim
20 words
The system of claim 15 wherein said distal end of said tube is closed or open up to 2 D.
