| U.S. Cl. 604—180 | 10 Claims |
| 1. A catheter anchor device for use with a catheter, the anchor device comprising:
a stationary base secured to the patient;
a rotatable ring secured to the stationary base such that the rotatable outer ring can be rotated by the user relative to
the stationary base;
one or more sutures positioned internally within the rotatable ring such that actuation of the rotatable ring automatically
deploys the one or more sutures from within the rotatable ring to engage a sidewall of the catheter and to secure the catheter
relative to the rotatable ring;
a ratchet mechanism mechanically operable with the rotatable ring such that when a user rotates the rotatable ring, the ratchet
mechanism is engaged during rotation of the rotatable ring, the ratchet mechanism comprising a rotatable ratchet member which
maintains cooperative engagement of the components of the ratchet mechanism allowing movement of the rotatable ring in a first
direction while minimizing inadvertent movement of the rotatable ring in a second direction securing the rotational position
of the rotatable ring against movement in the second direction;
means for retaining the one or more sutures in a desired location relative to the base; and
means for biasing, the means for biasing cooperating with the means for retaining to aid in retention of the one or more sutures
in a desired location relative to the base.
