In one embodiment, an implantable anchor for holding a catheter in place within a patient, comprises a body comprising a channel for holding the catheter; a plurality of apertures such that at least one aperture is disposed on each side of the spiral channel; and one or more suture structures to allow a surgeon to suture the anchor to tissue of the patient; wherein when a catheter is disposed within the channel and is threaded through the plurality of apertures, the plurality of apertures limit longitudinal displacement of the catheter in either longitudinal direction relative to the anchor without continuously applying a compressive force to the catheter. |
