Methods and systems for performing a medical procedure
Method and system for treating a patient using a compressible, pressure-attenuating device. According to one embodiment, the system is used to treat urinary tract disorders and can include one or more of an access device, a delivery device, a pressure-attenuating device, and a removal device. The access device may be used to create a passageway to an anatomical structure, such as the patient's bladder. The delivery device may be inserted through the passageway created by the access device and may be used to deliver the pressure-attenuating device to the anatomical structure. The removal device may be inserted through the passageway created by the access device and may be used to view the bladder and/or to capture, to deflate and to remove the pressure-attenuating device.
1. A medical device, the medical device comprising an implantable inflatable cell having a cell wall and a valve, the valve configured to allow or prevent access to an interior of the inflatable cell defined by the cell wall to inflate or deflate the cell and to allow the inflatable cell to be implanted within a body in a deflated state to then be inflated to an inflated state;
wherein the interior of the inflatable cell increases in volume by at least 10%, but less than 50% when internal pressure increases by 30 cmH2O from the cell volume at zero pressure; and
wherein the inflatable cell is made of polyurethane.
2. The medical device of claim 1 , wherein the inflatable cell increases in volume by at least 15% from the cell volume at zero pressure.
3. The medical device of claim 1 , wherein the inflatable cell has a wall thickness of between about 0.0001 and about 0.25 inches.
4. The medical device of claim 1 , wherein the inflatable cell has a wall thickness of between about 0.0003 and about 0.005 inches.
5. The medical device of claim 1 , wherein the inflatable cell has an initial volume between about 0.1 cc and about 500 cc.
6. The medical device of claim 1 , wherein the inflatable cell has an initial volume between about 1 cc and about 180 cc.
7. The medical device of claim 1 , further comprising an inflation media comprising a high vapor pressure media.
8. A medical device, the medical device comprising an implantable inflatable cell having a cell wall and a valve, the valve configured to allow or prevent access to an interior of the inflatable cell defined by the cell wall to inflate or deflate the cell and to allow the inflatable cell to be implanted within a body in a deflated state to then be inflated to an inflated state;
wherein the interior of the inflatable cell increases in volume by at least 6%, but less than 12% when internal pressure increases by 15 cmH2O from the cell volume at zero pressure, the inflatable cell having a wall thickness of between about 0.0003 and about 0.005 inches.
9. The medical device of claim 8 , wherein the inflatable cell increases in volume by at least 10% from the cell volume at zero pressure.
10. The medical device of claim 8 , wherein the inflatable cell has a wall thickness of between about 0.0009 and about 0.0015 inches.
11. The medical device of claim 8 , wherein the inflatable cell is made of polyurethane.
12. The medical device of claim 8 , wherein the inflatable cell has an initial volume between about 0.1 cc and about 500 cc.
13. The medical device of claim 8 , wherein the inflatable cell has an initial volume between about 1 cc and about 180 cc.
14. The medical device of claim 8 , further comprising an inflation media comprising a high vapor pressure media.
15. A medical device, the medical device comprising an implantable inflatable cell having a cell wall and a valve, the valve configured to allow or prevent access to an interior of the inflatable cell defined by the cell wall to inflate or deflate the cell and to allow the inflatable cell to be implanted within a body in a deflated state to then be inflated to an inflated state;
wherein the interior of the inflatable cell increases in volume by at least 15%, but less than 24% when internal pressure increases by 30 cmH2O from the cell volume at zero pressure.
16. The medical device of claim 15 , wherein the inflatable cell has a wall thickness of between about 0.0003 and about 0.005 inches.
17. The medical device of claim 15 , wherein the inflatable cell is made of polyurethane.
18. The medical device of claim 15 , wherein the inflatable cell has an initial volume between about 0.1 cc and about 500 cc.
19. The medical device of claim 15 , wherein the inflatable cell has an initial volume between about 1 cc and about 180 cc.
20. The medical device of claim 15 , further comprising an inflation media comprising a high vapor pressure media.
21. A method of treating a patient comprising delivering the inflatable cell of claim 8 into a bladder in the deflated state and while within the bladder, inflating the implantable inflatable cell through the valve to the inflated state.
22. A method of treating a patient comprising delivering the inflatable cell of claim 1 into a bladder in the deflated state and while within the bladder, inflating the implantable inflatable cell through the valve to the inflated state.
23. A method of treating a patient comprising delivering the inflatable cell of claim 15 into a bladder in the deflated state and while within the bladder, inflating the implantable inflatable cell through the valve to the inflated state.
