摘要:
Residence devices for long term delivery of therapeutic compounds and/or for sensing one or more relevant parameters in vivo are disclosed. In one embodiment, a residence device may include a plurality of links interconnected by a corresponding plurality of flexible hinges to permit the residence device to be deformed into a contracted configuration and subsequently permitted to return to an expanded configuration once positioned in a desired location, such as the stomach, of a subject. In some instances, at least a portion of the interconnected links may include a first link segment, a second link segment, and a coupling that selectively connects the first link segment to the second link segment. The coupling may be configured to weaken or decouple a connection between the first link segment and the second link segment when exposed to a temperature greater than a threshold temperature to selectively weaken and/or disassemble the residence device.
