Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
99 words
A device for compacting cancellous bone comprising a support tube, a first expandable body and a second expandable body carried by the support tube, each expandable body having a collapsed geometry permitting the first and second expandable bodies to be simultaneously deployed inside a bone, and a common flow channel in the support tube communicating jointly with each expandable body and adapted to be coupled to a source of an expansion medium to convey the expansion medium simultaneously into the first and second expandable bodies to cause simultaneous expansion of both expandable bodies inside bone to compact cancellous bone.
Claim 2
Independent Claim
99 words
A device for compacting cancellous bone comprising a support tube, a first expandable body and a second expandable body carried by the support tube, each expandable body having a collapsed geometry permitting the first and second expandable bodies to be simultaneously deployed inside a bone, and a common flow channel in the support tube communicating jointly with each expandable body and adapted to be coupled to a source of an expansion medium to convey the expansion medium simultaneously into the first and second expandable bodies to cause simultaneous expansion of both expandable bodies inside bone to compact cancellous bone.
Claim 3
Dependent Claim
22 words
A device according to claim 1 wherein the second expandable body is joined in a side-to-side relationship to the first expandable body.
Claim 4
Dependent Claim
38 words
A device according to claim 1 wherein at least one of the expandable bodies includes a wall and includes changes in thickness of the wall to constrain expansion of the at least one expandable body in cancellous bone.
Claim 5
Dependent Claim
41 words
A device according to claim 1 wherein at least one of the expandable bodies includes further includes an internal restraint coupled to the at least one expandable body to constrain expansion of the at least one expandable body in cancellous bone.
Claim 6
Dependent Claim
13 words
A device according to claim 4 wherein the internal restraint includes mesh material.
Claim 7
Dependent Claim
13 words
A device according to claim 4 wherein the internal restraint includes string material.
Claim 8
Dependent Claim
14 words
A device according to claim 4 wherein the internal restraint includes a woven material.
Claim 9
Dependent Claim
13 words
A device according to claim 4 wherein the internal restraint includes a seam.
Claim 10
Dependent Claim
15 words
A device according to claim 4 wherein the internal restraint includes an essentially non-elastic material.
Claim 11
Dependent Claim
41 words
A device according to claim 1 wherein at least one of the expandable bodies includes further includes an external restraint coupled to the at least one expandable body to constrain expansion of the at least one expandable body in cancellous bone.
Claim 12
Dependent Claim
13 words
A device according to claim 10 wherein the external restraint includes mesh material.
Claim 13
Dependent Claim
13 words
A device according to claim 10 wherein the external restraint includes string material.
Claim 14
Dependent Claim
14 words
A device according to claim 10 wherein the external restraint includes a woven material.
Claim 15
Dependent Claim
13 words
A device according to claim 10 wherein the external restraint includes a seam.
Claim 16
Dependent Claim
15 words
A device according to claim 10 wherein the external restraint includes an essentially non-elastic material.
Claim 17
Dependent Claim
32 words
A device according to claim 1 wherein at least one of the expandable bodies includes at least two materials that constrain expansion of the at least one expandable body in cancellous bone.
Claim 18
Dependent Claim
17 words
A device according to claim 16 wherein the at least two materials possess essentially similar elastic properties.
Claim 19
Dependent Claim
17 words
A device according to claim 16 wherein the at least two materials possess essentially different elastic properties.
Claim 20
Dependent Claim
32 words
A device according to claim 1 wherein the first and second expandable bodies include material that, during the simultaneous expansion in cancellous bone, applies a force capable of moving fractured cortical bone.
Claim 21
Dependent Claim
87 words
A device according to claim 1 further including at least one additional expandable body carried by the support tube having a collapsed geometry permitting the at least one additional expandable body to be simultaneously deployed inside the bone with the first and second expandable bodies, and wherein the common flow channel communicates with each expandable body and conveys the expansion medium simultaneously into the first, second, and at least one additional expandable bodies to cause simultaneous expansion of all expandable bodies inside bone to compact cancellous bone.
