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

摘要

At least one elongated tension-able body is sized and configured for implantation in a desired orientation in a tissue region in an airway. An array of projections extend from the elongated tension-able body, which are sized and configured to engage tissue and resist a reorientation of the elongated tension-able body within the tissue region out of the desired orientation.
