Abstract:
A method of producing a delivery device for the controlled release of a bioactive substance, which comprises the steps of:(a) forming a generally elongate structure by melt processing extrusion and extrusion when heated of one or more pharmaceutically or veterinarily acceptable polymeric materials so as to coat a core material containing the bioactive substance, the coating structure having an internal cavity extending at least substantially along its length, and wherein, the internal cavity of the coating structure is capable of receiving the core material; (b) inserting the core material into the internal cavity of the coating structure; (c) compressing the coating structure at a first location along its length so as to generally form a seal at that location; and (d) compressing the coating structure at a second location along its length.
