An implantable therapy lead is disclosed herein. The lead includes an elongated lead body having a suture sleeve. The suture sleeve is supported on the lead body and has each of an outer surface and an inner surface radially inward of the outer surface. The inner surface defines a lumen through which the elongated lead body extends. The suture sleeve further includes a structure projecting radially inward and/or outward from the inner surface. The suture sleeve is compressible from a first state into a second state by applying a constrictive force to the outer surface of the suture sleeve such that, when in the second state, the structure contacts the elongated lead body, at least in part, to resist movement of the elongated lead body relative to the suture sleeve.
