An implant for use in a human or animal body can include a flexible housing with an outer wall and having a chamber therein. The implant can have at least one high vapor pressure medium within the chamber. The at one high vapor pressure medium can have a combined vapor pressure equal to or greater than about the average value of the hydrostatic pressure of the implantation site plus the skin tension of the housing minus the gas tension of the dissolved gasses present at the implantation site.

1. A device for use in a human or animal body, comprising: a flexible housing comprising an outer wall and defining a chamber therein; andat least one high vapor pressure medium having a vapor pressure greater than the pressure in an anatomical structure and a low permeability rate through the outer wall of less than 1 ml/day at body temperature;wherein said high vapor pressure medium is a liquid at body temperature. 2. A device as in claim 1, wherein said high vapor pressure media comprises at least one of heptafluoropropane, perfluorooctylbromide, perfluorohexane, perfluorodecalin, tetrafluoroethane, sulfur hexafluoride, hexafluoroethane, perfluoropropane, perfluorobutane, perfluoropentane, perfluoroheptane, perfluorooctane, octafluoropropane, decafluoro-n-butane and perfluoroperhydrophenanthrene. 3. A device as in claim 1, wherein said high vapor pressure medium has a solubility of less than about 0.1 ml per ml of urine at body temperature and pressure. 4. A device as in claim 1, wherein said housing is configured to be positioned within an anatomical structure while in a first, introduction configuration and then at least partially inflated into a second, implanted configuration. 5. A device as in claim 1, wherein said device is an inflatable attenuation device. 6. A device as in claim 1, wherein said device is an implantable pressure attenuation device. 7. A device as in claim 1, wherein the at least one high vapor pressure medium comprises a vapor and a reservoir of liquid. 8. A device as in claim 1, wherein the device is a device for attenuating and/or baffling transient pressure waves in relatively incompressible materials in organs in a human or animal body. 9. A device as in claim 1, wherein the device is adapted to reversibly occupying intraorgan space. 10. A device as in claim 1, wherein the outer wall is made of a gas permeable material that allows permeation of gas at a rate of at least 15 ml per twelve months in or out of the device. 11. A device as in claim 1, wherein said anatomical structure is the bladder. 12. A device for use in a human or animal body, comprising: a flexible housing comprising an outer wall and defining a chamber therein; andat least one high vapor pressure medium having a vapor pressure greater than the pressure in an anatomical structure and a low permeability rate through the outer wall of less than 1 ml/day at body temperature;wherein said high vapor pressure medium has a solubility of less than about 0.1 ml per ml of urine at body temperature and pressure. 13. A device as in claim 12, wherein said high vapor pressure media comprises at least one of heptafluoropropane, perfluorooctylbromide, perfluorohexane, perfluorodecalin, tetrafluoroethane, sulfur hexafluoride, hexafluoroethane, perfluoropropane, perfluorobutane, perfluoropentane, perfluoroheptane, perfluorooctane, octafluoropropane, decafluoro-n-butane and perfluoroperhydrophenanthrene. 14. A device as in claim 12, wherein said housing is configured to be positioned within an anatomical structure while in a first, introduction configuration and then at least partially inflated into a second, implanted configuration. 15. A device as in claim 12, wherein said device is an inflatable attenuation device. 16. A device as in claim 12, wherein said device is an implantable pressure attenuation device. 17. A device as in claim 12, wherein the at least one high vapor pressure medium comprises a vapor and a reservoir of liquid. 18. A device as in claim 12, wherein the device is a device for attenuating and/or baffling transient pressure waves in relatively incompressible materials in organs in a human or animal body. 19. A device as in claim 12, wherein the outer wall is made of a gas permeable material that allows permeation of gas at a rate of at least 15 ml per twelve months in or out of the device. 20. A device for use in a human or animal body, comprising: a flexible housing comprising an outer wall and defining a chamber therein, wherein the outer wall is made of a gas permeable material that allows permeation gas at a rate of at least 15 ml per twelve months in or out of the device; andat least one high vapor pressure medium having a vapor pressure greater than the pressure in an anatomical structure and a low permeability rate through the outer wall of less than 1 ml/day at body temperature. 21. A device as in claim 20, wherein said high vapor pressure media comprises at least one of heptafluoropropane, perfluorooctylbromide, perfluorohexane, perfluorodecalin, tetrafluoroethane, sulfur hexafluoride, hexafluoroethane, perfluoropropane, perfluorobutane, perfluoropentane, perfluoroheptane, perfluorooctane, octafluoropropane, decafluoro-n-butane and perfluoroperhydrophenanthrene. 22. A device as in claim 20, wherein said housing is configured to be positioned within an anatomical structure while in a first, introduction configuration and then at least partially inflated into a second, implanted configuration. 23. A device as in claim 20, wherein said device is an inflatable attenuation device. 24. A device as in claim 20, wherein said device is an implantable pressure attenuation device. 25. A device as in claim 20, wherein the at least one high vapor pressure medium comprises a vapor and a reservoir of liquid. 26. A device as in claim 20, wherein the device is adapted to reversibly occupying intraorgan space. 27. A device as in claim 20, wherein said anatomical structure is the bladder.
