Abstract: The present technology may comprise a fixation device. The fixation device can comprise an elongate body comprising a plurality of interconnected segments, each of the segments comprising an engagement member, a recess configured to receive the engagement member of an adjacent one of the segments, and a plurality of channels. At least one of the channels can extend through the engagement member. The fixation device can further comprise a plurality of flexible elongate members, each extending through one of the channels. The elongate body can be transformable between a flexible configuration in which the elongate members can move relative to one another and a rigid configuration in which the elongate members are fixed relative to one another.

Abstract: Implantable intramedullary devices, and systems and methods related thereto, are provided which enable the delivery of a liquid material into an intramedullary channel. An implantable intramedullary device may include a delivery channel through which liquid material may be delivered through the device into the intramedullary channel. The intramedullary device may be adapted for coupling to a fluid delivery apparatus which delivers the liquid material into the delivery channel of the intramedullary device. Delivery catheters configured for insertion into implantable intramedullary devices are also disclosed. Liquid materials which may be delivered include bone cement, biologics, pharmacologic solutions, and other materials useful in conjunction with treatments involving intramedullary implants.
