METHODS AND DEVICES FOR DEPLOYING AND RELEASING A TEMPORARY IMPLANT WITHIN THE BODY

摘要

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.

主权项

1. A device for temporarily occupying a space within a patient's body, the device comprising:
a device assembly comprising a 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, where delivery of a filler material into the reservoir causes expansion of the device assembly towards the active profile; where an extension of the device assembly extends into the reservoir to form a boundary defining a release channel; a release material located within the reservoir and coupled to the release channel to prevent fluid flow therethrough; and wherein exposure of the release material to the filler material reduces a structural integrity of the release material sufficient to allow fluid flow through the release channel and causing the filler material to exit the reservoir.
