摘要： Described are gastric residence structures that include an active substance. The gastric residence structures may include one or more arms that include a loadable polymeric component, an elastic polymeric component, and a separate linker component. The linker may connect the one or more arms with the elastic polymeric component. The gastric residence structures may be configured to be folded and physically constrained during administration and may be configured to assume an open retention shape upon removal of a constraint. The change between the folded shape and the open retention shape may be mediated by the elastic polymeric component that undergoes elastic deformation when the residence structure is in the folded shape and recoils when the gastric residence structure assumes the open retention shape.

摘要： Residence structures, systems, and related methods are generally provided. Certain embodiments comprise administering (e.g., orally) a residence structure to a subject (e.g., a patient) such that the residence structure is retained at a location internal to the subject for a particular amount of time (e.g., at least about 24 hours) before being released. The residence structure may be, in some cases, a gastric residence structure. In some embodiments, the structures and systems described herein comprise one or more materials configured for high levels of active substances (e.g., a therapeutic agent) loading, high active substance and/or structure stability in acidic environments, mechanical flexibility and strength in an internal orifice (e.g., gastric cavity), easy passage through the GI tract until delivery to at a desired internal orifice (e.g., gastric cavity), and/or rapid dissolution/degradation in a physiological environment (e.g., intestinal environment) and/or in response to a chemical stimulant (e.g., ingestion of a solution that induces rapid dissolution/degradation). In certain embodiments, the structure has a modular design, combining a material configured for controlled release of therapeutic, diagnostic, and/or enhancement agents with a structural material necessary for gastric residence but configured for controlled and/or tunable degradation/dissolution to determine the time at which retention shape integrity is lost and the structure passes out of the gastric cavity. For example, in certain embodiments, the residence structure comprises a first elastic component, a second component configured to release an active substance (e.g., a therapeutic agent), and, optionally, a linker. In some such embodiments, the linker may be configured to degrade such that the residence structure breaks apart and is released from the location internally of the subject after a predetermined amount of time.

摘要： In accordance with the invention, compositions, devices, and related methods have been developed for medical-related and other applications. In some embodiments, the devices and compositions described herein comprise a triggerable shape memory polymer network. In certain embodiments, the polymer network comprises a covalently crosslinked polymeric material and a non-crosslinked polymeric material associated with the crosslinked polymeric material. In some cases, the polymer network has a first configuration (e.g., as polymerized), and a second configuration (e.g., upon heating and deformation), such that the polymer network can be triggered to recover the first configuration upon heating the polymeric material above a softening temperature of the polymeric material. In certain embodiments, the polymer network comprises a plurality of particles capable of increasing the temperature of the polymer network (e.g., above the softening temperature) in the presence of an external stimulus such as induction, radio frequency, or magnetic resonance, such that the polymer network changes configuration. The polymeric material may be molded into any suitable shape.
