| 1. A catheter anchor device, the catheter anchor device comprising:
a base;
a rotatable ring coupled to the base and arranged for movement relative to the base; and
a first suture and additional sutures coupled to the rotatable ring, the first suture including a loop portion and first and
second ends, the loop portion looping around a catheter when the anchor device is in place relative to a catheter insertion
site, the first suture being arranged relative to the base and catheter such that a predetermined rotation of the rotatable
ring deploys at least the first suture to cause the loop portion of the first suture to engage a wall of the catheter and
wherein additional rotation of the rotatable ring corresponds with a relative increase in tension of the first suture about
the catheter;
means for tensioning a suture, the means serving to enable tensioning of at least one suture about the catheter; and
a ratchet mechanism operably disposed with respect to the rotatable ring, the ratchet mechanism comprising a rotatable ratchet
member which maintains cooperative engagement of the components of the ratchet mechanism such that the rotatable ring is rotatable
in a first direction and is not rotatable in a second direction.
