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.
Claims20
A medical device for use with a fluid filler material and for occupying a space within a patient's body, the medical device comprising:
- a device body having an interior reservoir, the device body having a deployment profile and expandable to an active profile upon receiving the fluid filler material within the interior reservoir;
- a fill valve configured to deliver the fluid filler material into the interior reservoir;
- and
- a release channel providing a first fluid path between an exterior of the device body and the interior reservoir;
- an energy storage element coupled to the release channel;
- a restraining element that closes the release channel and compresses the energy storage element, 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 until the fluid filler material reduces a structural integrity of the restraining element to unseal the release channel and cause expansion of the energy storage element to assist in opening the release channel, wherein the restraining element is monolithic.
A medical device for use with a fluid filler material and for occupying a space within a patient's body, the medical device comprising:
- a device body having an interior reservoir, the device body having a deployment profile and expandable to an active profile upon receiving the fluid filler material within the interior reservoir;
- a fill valve configured to deliver the fluid filler material into the interior reservoir;
- and
- a release channel configured to control flow through a first fluid path, where the first 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 first fluid path and having an open configuration permitting flow of the fluid filler material through the first fluid path;
- and
- wherein in the sealed configuration, a restraining element compresses an energy storage element such that when compressed the energy storage element applies a tensile force on the restraining element, such upon degradation of the restraining element by the fluid filler material, the energy storage element expands to assist the release channel in assuming the open configuration.
