A ratchet mechanism having one or more rotatable ratchet members which pivot and a ratchet member engagement spring which maintains contact between the teeth of the rotatable ratchet member and the teeth of the ratchet ring. An O-ring is provided to maintain the position of the sutures to minimize disruption of the sutures before deployment of the sutures. In one embodiment, a stationary base of the anchor device comprises a single molded member. In another embodiment a method of manufacturing the catheter anchor device comprising welding a rotatable ring and one or more bearing members of the catheter anchor device through access bores in the stationary base.
