Claim Text:
1. A medical device for occupying a space within a patient's body with a filler material, the medical device comprising: a device assembly comprising a reservoir and having a release channel defining a lumen; a release material located within the reservoir and completely surrounding the release channel where the release material compresses an exterior of the release channel to prevent fluid flow through the lumen of the release channel; a valve on the device assembly and in fluid communication with the reservoir, where the valve permits delivery of the filler material into the reservoir; the device assembly having a deployment profile and an active profile, where the deployment profile is smaller than the active profile and permits deployment of the device assembly within a space in the patient's body and where the device assembly expands to the active profile upon delivery of the filler material; and wherein exposure of the release material to the filler material reduces a structural integrity of the release material opening the release channel to allow fluid flow through the lumen of the release channel and causing the filler material to pass into the space within the patient's body resulting in reduction of a size of the active profile.
