Ballistically implantable shaped body for the controlled release of active substance

摘要

The shaped body (10, 40) comprising a biocompatible polymer and at least one biologically active substance (22) is ballistically implanted in animal tissue. The biologically active substance can be located in a cavity of the projectile or can be distributed within the entire projectile inside a matrix maintaining release. By contact with the body fluids of the animal, the biologically active substance (22) is then released in a protracted manner. <IMAGE>
