Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
202 words
An assembly for injecting flowable material into bone comprising a tubular body including an interior bore to carry a material flow, the tubular body having a longitudinal axis and including a dispensing end, an opening in the dispensing end communicating with the bore to dispense the material flow, a plunger located at least partially within the tubular body, the plunger adapted to be displaced along the longitudinal axis of the tubular body, an advancement mechanism attached to the plunger, a first advancement screw adapted to actuate the advancement mechanism to displace the plunger a first longitudinal displacement in a first direction in response to rotation of the first advancement screw in a first direction and to displace the plunger a first longitudinal displacement in a second direction in response to rotation of the first advancement screw in a second direction, and a second advancement screw adapted to actuate the advancement mechanism to displace the plunger a second longitudinal displacement in a first direction in response to rotation of the second advancement screw in a first direction and to displace the plunger a second longitudinal displacement in a second direction in response to rotation of the second advancement screw in a second direction.

Claim 3
Dependent Claim
16 words
The assembly of claim 1 , wherein the advancement mechanism comprises a plurality of threaded screws.
Claim 4
Dependent Claim
15 words
The assembly of claim 1 wherein the first and second advancement screws are co-axially oriented.
Claim 5
Dependent Claim
19 words
The assembly of claim 1 wherein the first advancement screw is actuated by rotation of a first control knob.
Claim 6
Dependent Claim
25 words
The assembly of claim 4 , wherein a complete rotation of the first control knob causes the plunger to displace approximately one half (½) inch.
Claim 7
Dependent Claim
54 words
The assembly of claim 4 , wherein a complete clockwise rotation of the first control knob causes the plunger to advance approximately one half (½) inch into the tubular body, and a complete counter-clockwise rotation of the first control knob causes the plunger to withdraw approximately one half (½) inch from the tubular body.
Claim 8
Dependent Claim
39 words
The assembly of claim 4 , wherein the rotation of the first control knob causes the plunger to advance towards the material, and the counter-rotation of the first control knob causes the plunger to draw away from the material.
Claim 9
Dependent Claim
19 words
The assembly of claim 1 wherein the second advancement screw is actuated by rotation of a second control knob.
Claim 10
Dependent Claim
26 words
The assembly of claim 8 , wherein a complete rotation of the second control knob causes the plunger to displace approximately one sixteenth ({fraction (1/16)}) inch.
Claim 11
Dependent Claim
165 words
An assembly for injecting flowable material into bone comprising a tubular body including an interior bore to carry a material flow, the tubular body having a longitudinal axis and including a dispensing end, an opening in the dispensing end communicating with the bore to dispense the material flow, a plunger located at least partially within the tubular body, the plunger adapted to be displaced along the longitudinal axis of the tubular body, an advancement mechanism attached to the plunger, a first control element adapted for movement in a first direction to actuate the advancement mechanism to displace the plunger a first longitudinal displacement in a first direction, and a second control element adapted for movement in a first direction to actuate the advancement mechanism to displace the plunger a second longitudinal displacement in a first direction, at least one of the first and second control elements being operable in a second direction to actuate the advancement mechanism to displace the plunger in a second direction.
Claim 12
Dependent Claim
165 words
An assembly for injecting flowable material into bone comprising a tubular body including an interior bore to carry a material flow, the tubular body having a longitudinal axis and including a dispensing end, an opening in the dispensing end communicating with the bore to dispense the material flow, a plunger located at least partially within the tubular body, the plunger adapted to be displaced along the longitudinal axis of the tubular body, an advancement mechanism attached to the plunger, a first control element adapted for movement in a first direction to actuate the advancement mechanism to displace the plunger a first longitudinal displacement in a first direction, and a second control element adapted for movement in a first direction to actuate the advancement mechanism to displace the plunger a second longitudinal displacement in a first direction, at least one of the first and second control elements being operable in a second direction to actuate the advancement mechanism to displace the plunger in a second direction.
Claim 13
Dependent Claim
122 words
An assembly for injecting flowable material into bone comprising a tubular body including an interior bore to carry a material flow, the tubular body having a longitudinal axis and including a dispensing end, an opening in the dispensing end communicating with the bore to dispense the material flow, a plunger located at least partially within the tubular body, the plunger adapted to be displaced along the longitudinal axis of the tubular body, and an advancement mechanism attached to the plunger, whereby the advancement mechanism is operable in a first mode to displace the plunger a first longitudinal distance and in a second mode to displace the plunger a second longitudinal distance, the second longitudinal distance being different than the first longitudinal distance.
Claim 14
Dependent Claim
