摘要：
Self-righting articles, such as self-righting capsules for administration to a subject, are generally provided. In some embodiments, the self-righting article may be configured such that the article may orient itself relative to a surface (e.g., a surface of a tissue of a subject). The self-righting articles described herein may comprise one or more tissue engaging surfaces configured to engage (e.g., interface with, inject into, anchor) with a surface (e.g., a surface of a tissue of a subject). In some embodiments, the self-righting article may have a particular shape and/or distribution of density (or mass) which, for example, enables the self-righting behavior of the article. In some embodiments, the self-righting article may comprise a tissue interfacing component and/or a pharmaceutical agent (e.g., for delivery of the active pharmaceutical agent to a location internal of the subject). In some cases, upon contact of the tissue with the tissue engaging surface of the article, the self-righting article may be configured to release one or more tissue interfacing components. In some cases, the tissue interfacing component is associated with a self-actuating component. For example, the self-righting article may comprise a self-actuating component configured, upon exposure to a fluid, to release the tissue interfacing component from the self-righting article. In some cases, the tissue interfacing component may comprise and/or be associated with the pharmaceutical agent (e.g., for delivery to a location internal to a subject).D'une manière générale, l'invention concerne des articles à auto-actionnement comprenant, par exemple, des aiguilles à actionnement automatique et/ou des poinçons de biopsie à auto-actionnement. De manière avantageuse, les articles à auto-actionnement décrits ici peuvent être utiles en tant que plate-forme générale pour l'administration de divers médicaments pharmaceutiques qui sont habituellement administrés par injection directement dans un tis
