The Marrow Cellution™ MC Ran 11CSTS Bone Marrow Aspiration Harvesting System is a longer version of the MC Ran 11C novel bone marrow access and retrieval device that incorporates features designed to minimize limitations of traditional trocar needles for large or obese patients.

Marrow Cellution™ accesses aspirate flow collected exclusively laterally as the tip of the aspiration cannula is closed allowing marrow collection perpendicular to and around the channel created by the device. It incorporates technology to precisely reposition the retrieval cannula within the marrow space after each aspiration. These features achieve a clinicians‘ desire for a single entry point. 

Marrow Cellution™ allows for easy access through soft tissue and cortical bone. A fenestrated blunt trocar is then introduced to create access for closed end, side port aspiration stylet. The design minimizes trauma to cancellous bone and marrow, thereby mitigating pooling of peripheral blood. 

The patent pending design consists of a closed end stylet which forces aspiration of marrow laterally from the marrow space. The manual rotation of the handle allows the fenestrated stylet to be raised to a desired position in a new level of undisturbed marrow for subsequent aspiration aliquots. From a single stick, Marrow Cellution™ is capable of collecting up to 10ml of high quality bone marrow equivalent or superior to other systems that require additional manipulation steps such as centrifugation or chemical separation in a laboratory.
