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 to inflate or deflate the cell and to allow the inflatable cell to be implanted within a body in an inflated state;
wherein a burst force of the inflatable cell when in the inflated state is greater than 4.9 pounds when a compressive force is applied by a piston on the inflatable cell within a fixture configured to limit expansion of the inflatable cell once the compressive force is applied, the fixture having a hole of 0.575 inches in diameter, the inflatable cell being compliant so that the cell wall expands out of the fixture through the hole when the compressive force is an applied pressure of 4.25 pounds;
wherein the inflatable cell when in the inflated state has an outer dimension greater than 0.575 inches.
2. The medical device of claim 1 , wherein the inflatable cell has a burst force greater than 7 pounds.
3. The medical device of claim 1 , wherein the inflatable cell has a wall thickness of between about 0.0003 and about 0.005 inches.
4. The medical device of claim 1 , wherein the inflatable cell has a wall thickness of between about 0.0009 and about 0.0015.
5. The medical device of claim 1 , wherein the inflatable cell is made of one or more of silicone, estane polyurethane, and pelethane polyurethane.
6. The medical device of claim 1 , wherein the inflatable cell has an initial volume of about 18 ml or about 30 ml.
7. The medical device of claim 1 , further comprising an inflation media comprising a gas.
8. The medical device of claim 7 , wherein the inflation media further comprises a liquid.
9. 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 to inflate or deflate the cell and to allow the inflatable cell to be implanted within a body in an inflated state:
wherein the inflatable cell when in the inflated state deforms less than 10 millimeters thru a hole of 0.575 inches in diameter with an applied pressure of 4.25 pounds when the applied pressure of 4.25 pounds is applied by a piston on the inflatable cell within a fixture configured to limit expansion of the inflatable cell once the compressive force is applied, the fixture having the hole, the inflatable cell being compliant so as to expand out of the fixture through the hole when the applied pressure of 4.25 pounds is applied;
wherein the inflatable cell when in the inflated state has an outer dimension greater than 0.575 inches.
10. The medical device of claim 9 , wherein the inflatable cell deforms less than 8 millimeters.
11. The medical device of claim 9 , wherein the inflatable cell deforms less than 6 millimeters.
12. The medical device of claim 9 , wherein the inflatable cell has a wall thickness of between about 0.0003 and about 0.005 inches.
13. The medical device of claim 9 , wherein the inflatable cell has a wall thickness of between about 0.0009 and about 0.0015.
14. The medical device of claim 9 , wherein the inflatable cell is made of one or more of silicone, estane polyurethane, and pelethane polyurethane.
15. The medical device of claim 9 , wherein the inflatable cell has an initial volume of about 18 ml or about 30 ml.
16. The medical device of claim 9 , further comprising an inflation media comprising a gas.
17. The medical device of claim 16 , wherein the inflation media further comprises a liquid.
18. The medical device of claim 9 , wherein when in the inflated state, the inflatable cell has a burst force greater than 4.9 pounds when a compressive force is applied on the inflatable cell within the fixture.
