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 medical device for use with a fluid filler material and for occupying a space within a patient's body, the medical device comprising:
a first fluid impermeable surface material forming 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 fluid tunnel ending within the interior reservoir; and a release channel formed by an interior of a second fluid impermeable material, where the release channel is in fluid communication with the interior reservoir and is temporarily fluidly sealed by a release material located in the interior reservoir about an exterior of the second fluid impermeable material to mechanically secure the second fluid impermeable material to fluidly seal the release channel and to prevent fluid transfer to or from the patient's body until the fluid filler material reduces the structural integrity of the release material to unseal the release channel.
