Abstract: Systems, devices, and methods are provided for creating bone tunnels. In particular, described herein are embodiments of bone tunneling devices configured to create curvilinear tunnels in bone, as well as methods and devices relating thereto.

Abstract: Systems, devices, and methods are provided for attaching and supporting a bone suture. In particular, described herein are embodiments of implantable bracing apparatuses comprising one or more curved tubes configured to be implanted in one or more bone tunnels, and further configured to pass one or more sutures therethrough. Embodiments of methods of creating a bracing apparatus in situ by injecting a fluidic agent into a bone tunnel and inducing a phase transition are also described. Furthermore, described herein are embodiments of tunneling devices for creating a bone tunnel, which can be used with any of the bracing apparatuses described herein.
