Abstract
Methods, devices and systems for delivering a device assembly into a gastric or other space within the body, allowing the device to expand to occupy volume within the gastric space and, after an effective period of time, delivering a substance or stimulus to begin breakdown of the expanded device so that it may release from the body.
Claims18
A medical device for occupying a space within a patient's body, the medical device comprising:
- a device body having an interior reservoir;
- a fluid filler material configured to expand within the interior reservoir;
- a fill valve configured to deliver the fluid filler material into the interior reservoir, wherein expansion of the fluid filler material increases pressure against the fill valve, wherein the fill valve comprises a first layer and a second layer and a flow control material between the first layer and the second layer, wherein the fill valve comprises a first fluid path between the first layer and the second layer, wherein the fluid filler material closes the first fluid path by pressing the first layer and the second layer toward the flow control material such that the first fluid path is closed;
- a release channel providing a second fluid path between an exterior of the device body and the interior reservoir;
- a restraining element that closes the release channel such that the restraining element temporarily fluidly constrains the release channel closed to prevent fluid transfer between the exterior of the device body and the interior reservoir, wherein the restraining element is monolithic;
- and
- wherein the fluid filler material degrades the restraining element to unseal the release channel.

- a release channel configured to control flow through a second-first fluid path, where the second fluid path extends between an exterior of the device body and the interior reservoir, the release channel having a sealed configuration preventing flow of the fluid filler material through the second fluid path and an open configuration permitting flow of the fluid filler material through the second fluid path;
- and
- a restraining element that closes the release channel in the sealed configuration such that the restraining element temporarily fluidly constrains the release channel closed to prevent fluid transfer between the exterior of the device body and the interior reservoir, wherein the restraining element is monolithic;
- and
- wherein the fluid filler material degrades the restraining element to unseal the release channel and to assist in opening the release channel.
