Implantable devices, systems, and methods for maintaining desired orientations in targeted tissue regions

摘要

At least one elongated body is sized and configured for implantation in a desired orientation in a tissue region in an airway. An array of projections extends from the elongated body and is resiliently coupled to the elongated body. The array or projections is in a normally biased outward extending condition sized and configured to engage tissue and resist a reorientation of the elongated body within the tissue region out of the desired orientation after implantation of the elongated body in the tissue region. The array of projections is sized and configured to resiliently yield by flexing inward against the elongated body during implantation of the elongated body in the tissue region.
