Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
110 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and said sleeve has an elliptical cross-section in a plane which is substantially perpendicular to the longitudinal axis.
Claim 2
Dependent Claim
110 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and said sleeve has an elliptical cross-section in a plane which is substantially perpendicular to the longitudinal axis.
Claim 3
Dependent Claim
163 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and a second wing; said central body having an end located distally from said first wing; a first sleeve guide extending from said first wing; and a first groove provided in said sleeve, such that with the sleeve received over said central body said first groove receives said first sleeve guide from said first wing so that said sleeve can rotate about said central body guided by said first sleeve guide.
Claim 4
Dependent Claim
163 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and a second wing; said central body having an end located distally from said first wing; a first sleeve guide extending from said first wing; and a first groove provided in said sleeve, such that with the sleeve received over said central body said first groove receives said first sleeve guide from said first wing so that said sleeve can rotate about said central body guided by said first sleeve guide.
Claim 5
Dependent Claim
20 words
The implant of claim 2 wherein said first guide include first and second pins extending from said first wing respectively.
Claim 6
Dependent Claim
11 words
The implant of claim 2 wherein said first grooves are curved.
Claim 7
Dependent Claim
121 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and said sleeve can rotate as the implant is inserted between spinous processes from a posterior position to an anterler position closer to vertebral bodies of the spinal column.
Claim 8
Dependent Claim
121 words
An implant for relieving pain associated with at least one of the spinal column and associated tissues and structures, which implant is positionable between spinous processes of the spinal column, the implant comprising: a first wing with a central body extending therefrom, said central body having a longitudinal axis; a sleeve positioned over said central body with said sleeve being able to rotate about said longitudinal axis of said central body so as to be positionable relative to said central body in order to aid in positioning said implant between spinous processes; and said sleeve can rotate as the implant is inserted between spinous processes from a posterior position to an anterler position closer to vertebral bodies of the spinal column.
