Abstract
Abstract The present invention is directed to an inflatable device for use in restoring the anatomy of diseased or fractured bone. The inflatable device may be a balloon of varied size or shape to conform to the bone to be treated and may be deployed in any type of bone where collapsed fractures of cortical bone may be treated by restoring the bone from its inner surface. Once the bone has been sufficiently restored the balloons may be deflated and removed, or may remain inside the bone. The balloon may have multiple layers to provide desired surface characteristics, resistance to puncture and tearing, or other beneficial properties, as appropriate for the particular application of the device.</PTEXT>

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
92 words
A method for treating bone comprising: creating a cavity in a bone treatment area; deploying an inflatable device inside the bone, the inflatable device having first and second components and applying a sealant to the treatment area prior to deployment of the inflatable device, wherein the first component is a barrier that forms a balloon wall and the second component comprises a thread for reinforcing the wall, and wherein the second component is molded onto the first component and the step of applying the sealant to the treatment area comprises spray coating.
Claim 2
Independent Claim
92 words
A method for treating bone comprising: creating a cavity in a bone treatment area; deploying an inflatable device inside the bone, the inflatable device having first and second components and applying a sealant to the treatment area prior to deployment of the inflatable device, wherein the first component is a barrier that forms a balloon wall and the second component comprises a thread for reinforcing the wall, and wherein the second component is molded onto the first component and the step of applying the sealant to the treatment area comprises spray coating.
Claim 3
Dependent Claim
14 words
The method of claim 1 , wherein the second component is a woven braid.
Claim 4
Dependent Claim
14 words
The method of claim 2 , wherein the woven braid forms a predetermined shape.
Claim 5
Dependent Claim
38 words
The method of claim 1 , wherein the step of applying the sealant further comprises: at least partially inflating the inflatable device within the treatment area; using the inflatable device to spread the sealant onto the treatment area.
Claim 6
Dependent Claim
23 words
The method of claim 4 , wherein the step of using the inflatable device to spread the sealant comprises rotating the inflatable device.
Claim 7
Dependent Claim
35 words
The method of claim 4 , wherein the step of using the inflatable device to spread the sealant comprises moving the device along an axis in which the device is deployed into the treatment area.
Claim 8
Dependent Claim
24 words
The method of claim 4 , further comprising the step of gradually inflating the inflatable device while spreading the sealant onto the treatment area.
Claim 9
Independent Claim
46 words
A method for treating bone comprising: forming a cavity in a bone treatment area; deploying an inflatable device in the cavity, the inflatable device comprising an outer wall and spray coating the treatment area with a sealant and a thread moldably coupled to the outer wall.
Claim 10
Independent Claim
46 words
A method for treating bone comprising: forming a cavity in a bone treatment area; deploying an inflatable device in the cavity, the inflatable device comprising an outer wall and spray coating the treatment area with a sealant and a thread moldably coupled to the outer wall.
Claim 11
Dependent Claim
34 words
The method of claim 8 , further comprising: at least partially inflating the inflatable device in the cavity; and contacting the inflatable device with a wall of the cavity to spread the sealant thereon.
Claim 12
Dependent Claim
17 words
The method of claim 9 , wherein the inflatable device rotatably contacts the wall of the cavity.
Claim 13
