Abstract: Intramedullary medical devices (e.g., intramedullary nails) and methods for their use and manufacture are described herein. The intramedullary medical devices described herein may provide sustained compressive forces across a bone fusion site despite bone resorption processes. Through various embodiments, the intramedullary medical devices described herein may provide non-linear force curves relative to displacement. Intramedullary medical devices are described with multiple elements made of different materials. Examples of intramedullary medical devices are described with shape memory alloys.

Abstract: Methods and systems are described which allow medical devices containing shape memory polymers to be stored and/or transported without temperature control. Temperature control can be used to inhibit activation of shape memory polymers. Embodiments of methods described herein include activating shape memory polymers while within packaging which inhibits shape change due to activation. Packaging systems are also described herein.

Abstract: Methods and systems have been developed allowing for increased strain storage in shape memory polymer devices. Larger stored strains allow for smaller and different implantable shapes of shape memory polymer devices. For example, by storing a larger strain, a shape memory polymer device may be implanted at a smaller fraction of its final implanted shape. Benefits include shorter patient recovery times, smaller implantation sites, and flexibility of implantation techniques.
