Abstract
An implant delivery system can be configured to deliver an inflatable implant into a bladder via a urethra. The delivery system can comprise an elongate tubular body, an inflation tube and an implant decoupler. The tubular body can comprise a central lumen configured to hold an inflatable implant in an initial un-inflated state for delivery of the implant into the bladder. A method of use can include passing a distal tip of the elongate tubular body into the bladder. The implant can be inflated and released into the bladder.

2. 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 within the chamber having a vapor pressure equal to or greater than Panatomical environment/hydrostatic-avg+PSkin-tension−
PDissolved gas in absolute pressure, wherein the one or more high vapor pressure medium comprises a vapor and a reservoir of liquid;wherein the reservoir of liquid is of sufficient initial quantity to maintain the high vapor pressure medium in the housing for the duration of a treatment period. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. An inflatable implant operable to maintain or increase inflation comprising:
-
a flexible housing comprising an outer wall defining a chamber, wherein the housing is configured to be positioned within the body while in a first, introduction configuration and then at least partially inflated into a second, implanted configuration; and one or more high vapor pressure media having a combined vapor pressure equal to or greater than about the value of the hydrostatic pressure of the implantation site or the desired increased hydrostatic pressure at the site and the skin tension of said housing minus the gas tension of the dissolved gasses present at said implantation site.

18. A method of treatment in a human or animal body comprising:
-
implanting an inflatable implant within the body, the inflatable implant device comprising a flexible housing comprising an outer wall defining a chamber; injecting into the chamber, while within the body, at least one high vapor pressure medium within the chamber having a vapor pressure equal to or greater than Panatomical environment/hydrostatic-avg+PSkin-tension−
PDissolved gas in absolute pressure, wherein the one or more high vapor pressure medium comprises a vapor and a reservoir of liquid; andvaporizing, while within the body, at least some of the liquid as the vapor leaves the chamber, thereby the vaporizing maintains the implant in an inflated state for the duration of a treatment period.
