Methods, systems and devices are provided which promote the uptake of one or more agents into cellular material, wherein incorporation of such agent(s) improve the intended performance of the material upon implantation. This is particularly applicable to vascular replacements wherein uptake of agents, such as nucleic acids, induces long-term stable adaptation of the vascular replacement involving resistance to neointimal hyperplasia and atherosclerosis. The promotion of such uptake is achieved with the use of vibrational energy, particularly ultrasound. The cellular material is immersed into an acoustically transmissive solution comprising the agent. The immersed material is then exposed to vibrational energy under conditions and for a time which promotes incorporation of the agent into the cells. Portable, convenient and easy to use systems and devices are also provided for use in conjunction with these methods.
