AU2020360407B2 — Self-sizing device for delivering a formulation to a lumen wall

USPTO Abstract

A system is provided for delivering a therapeutic formulation into a lumen. The system includes a self-sizing device comprising an expandable component that includes at least one non-compliant section structured to resist deformation in an expanded configuration, the expandable component further including at least one hinge structured to allow deformation in an expanded configuration, the expandable component structured to bend about the hinge upon expansion to adapt to an inner circumference of a lumen independent of the inner circumference of the lumen within a selected range. The system includes the therapeutic formulation and a delivery mechanism. The self-sizing device is structured to, upon expansion of the expandable component, cause the delivery mechanism to apply a force to the therapeutic formulation, the force designed to expel the therapeutic formulation from the self-sizing device. The self-sizing device may be disposed within a capsule.
