1. An injectable implantable device used in treating a medical condition when implanted into a subject, the device comprising:
at least one coaxially extruded fibre of a hydrophilic polymer and a hydrophobic polymer, wherein at least one of said polymers is loaded with an agent that is active towards treating the medical condition,
a sheath encapsulating the at least one coaxially extruded fiber substantially therein for protecting the at least one coaxially extruded fiber during implantation by injection and controlling release of the active agent from the at least one coaxially extruded fiber, wherein the sheath comprises a plurality of apertures disposed along the length of the sheath in a spaced apart arrangement, and
an echogenic locating means for use in locating the implantable device when implanted into a subject.
