Implant with high vapor pressure medium

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 pressure attenuation device for use in a body, the pressure attenuation device comprising:
 a balloon comprising an outer wall and defining an interior chamber therein, the balloon having a minimum wall thickness of between 0.0005 inches and 0.005 inches;   a high vapor pressure media is positioned within the interior cavity of the balloon, the high vapor pressure media having a vapor pressure of between 50 cm H 2 O-200 cm H 2 O and a low permeability rate through the outer wall of less than 1 ml/day at body temperature.   
     
     
         3 . A pressure attenuation device as in  claim 2 , 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. 
     
     
         4 . A pressure attenuation device as in  claim 2 , 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. 
     
     
         5 . A pressure attenuation device as in  claim 2 , 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. 
     
     
         6 . A pressure attenuation device as in  claim 2 , wherein said device is an implantable pressure attenuation device. 
     
     
         7 . A pressure attenuation device as in  claim 2 , wherein the at least one high vapor pressure medium comprises a vapor and a reservoir of liquid. 
     
     
         8 . A pressure attenuation device as in  claim 2 , 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 pressure attenuation device as in  claim 2 , wherein the device is adapted to reversibly occupying intraorgan space.
