1. A device for extended release of pharmaceutical products comprising:
an implantable bioabsorbable elongated member appearing as a strand having at least one sleeve slideable into a trocar for implantation;
said bioabsorbable elongated member being enabled to contain time-release pellets containing at least one pharmaceutical material;
said elongated member containing time-release pellets having a pre-determined pharmaceutical schedule for time release of said at least one pharmaceutical material from said elongated member containing time-release pellets;
said bioabsorbable elongated member being bioabsorbable;
said bioabsorbable elongated member having multiple varied polymeric strands having at least one layer of polymeric material, each said strand containing said time-release pellets, each said strand being formulated from a varying combination of bioabsorbable polymeric materials set to dissolve at varying times so that by the cooperation of the rate of dissolution of each said polymeric strand and the rate of time release of the time-release pellets contained within each said polymeric strand result in the time release of said at least one pharmaceutical material in each said strand corresponding to said pre-determined pharmaceutical schedule.
