Abstract
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.
Claims27
A device for use in a human or animal body, comprising:
- a flexible housing comprising an outer wall and defining a chamber therein;
- and
- at 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.
A device for use in a human or animal body, comprising:
- a flexible housing comprising an outer wall and defining a chamber therein;
- and
- at 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.
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;
- and
- at 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.
