K2M, Inc. has announced the international launch of revolutionary minimally invasive approach to dynamic fixation of the spine. The company received CE mark approval for POTOMAC Rod System and the SERENGETI Minimally Invasive Retractor System that enables the company for international distribution of these devices. POTOMAC Rod System is a simple and versatile one-piece rod designed to enhance the stabilization characteristics of the spine. The device will be distributed outside the US. The company has patented manufacturing process of the material properties of Nitinol, a shape memory alloy. The intrinsic elasticity of the rod provides stabilization of the spine, while potentially reducing problems typically associated with traditional fusion materials. Additionally, the simplistic design allows POTOMAC to be implanted using traditional surgical techniques or by using the innovative SERENGETI Minimally Invasive Retractor System. SERENGETI offers a novel approach for the insertion of spinal implants through very small incisions. This device was already being introduced into the market in 2007. This percutaneous approach has been designed to provide improved visualization and access for multi-level complex posterior instrumentation procedures.
