Abstract

An inflated implant, such as an attenuation device, previously implanted in a urinary bladder can later be removed according to a number of different methods. Preferably, removal is accomplished transurethrally. In one embodiment, removal is accomplished by reducing the inflated implant from an enlarged profile to a reduced profile so that it may be withdrawn transurethrally by a removal system. The removal system can be configured differently depending upon whether reduction from the enlarged profile to the reduced profile is accomplished by deflation, compression, and/or other ways.

Claims21

Dependent claims

An attenuation device for use in an anatomical structure of a subject, the attenuation device, comprising:

a flexible housing having an outer wall and defining a chamber therein;
at least one fluid having a first vapor pressure and a first permeability rate through the outer wall of the flexible housing, wherein the first vapor pressure is greater than a pressure in the anatomical structure of the subject, and wherein the at least one fluid comprises a quantity of vapor and a quantity of liquid;
and
at least one gas having a second permeability rate through the outer wall of the flexible housing, wherein the second permeability rate of the at least one gas through the outer wall of the flexible housing is greater than the first permeability rate of the at least one fluid through the outer wall of the flexible housing.
