Abstract: Anchors for use with implantable medical leads include an elastic body containing one or more rigid bodies that have longitudinal free edges. The longitudinal free edges run from end to end to define full length slots. Partial length slots may also be included within the one or more rigid bodies. The full length and partial length slots allow for deflection of the rigid bodies against the body of an implantable medical lead to hold the anchor in place on the lead. The full length slots allow a blade to pass through and cut a slit in the elastic body which allows the anchor to be removed from the lead.
