The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site. In one embodiment, the body is made from at least one sheet (12) of a biologically-compatible material, in one embodiment, the sleeve may be made in least in part from caprolactone to add stretchability to the sleeve.
