Reply from Steven Mayer, 3-25-96 with regard to infusion of drugs directly into blood. The type of infusion pump you describe in a general way should be available. You should contact a large medical supply house as a start. Also you should contact oncologists and endocrinologistswho do regional infusiions of cancer chemotherapeutic agents for chronic and large dose effects.Ican't be more specific, as thse are not my areas of experties. You will find something with persistence. Good luck. Steven E. Mayer, Ph.D. Steven E. Mayer, Ph.D.
