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 method for temporarily occupying a gastric space in a body of a patient, the method comprising:
providing a device assembly having a conduit comprising a flexible end portion, where the flexible end portion extends within an enclosed reservoir of the device assembly; deploying the device assembly within the gastric space; delivering a filler through the conduit such that the device assembly expands to an active profile that occupies an increased volume within the gastric space; and where the device assembly further comprises a section providing a fluid path out of the reservoir, where the section is temporarily sealed by a release material that is located within the enclosed reservoir and remains entirely exterior to the fluid path such that the release material is physically separated from the gastric space, until reduction of a structural integrity of the release material allows opening of the section to open the fluid path.
