1. An anchor system for use in securing a catheter to tissue, the system comprising:
- a catheter anchor placement tool comprising an elongate body portion, wherein the elongate body portion comprises a non-flexible outer cylindrical surface located between a first end and a second end of the elongate body portion, and further wherein the elongate body portion defines a lumen through the elongate body portion from the first end to the second end having a diameter that is greater than an outer diameter of the catheter to allow the catheter to pass through the catheter anchor placement tool; and
an anchor comprising a body member formed of a flexible material defining at least one opening through which the catheter is positioned when secured using the anchor, wherein the outer cylindrical surface of the catheter anchor placement tool is configured so as to hold the anchor thereon such that the inner diameter of the at least one opening defined through the anchor is greater than the outer diameter of the catheter when the anchor is positioned on the outer cylindrical surface.

- 14. An anchor for use in securing a catheter to tissue, the anchor comprising an elongate body member, wherein a channel is defined through the elongate body member from a first end to a second end thereof, wherein the cross-sectional inner diameter along at least a portion of the length of the channel is less than the outer diameter of the catheter when the anchor is in a normal state preventing the insertion of the catheter through the channel, and further wherein the anchor comprises a flexible material that allows the cross-sectional inner diameter along the portion of the length of the channel to be expanded to a cross-sectional inner diameter greater than the outer diameter of the catheter when the anchor is in a flexed state.

22. An anchor for use in securing a catheter to tissue, the anchor comprising:
-
an elongate body member, wherein a channel is defined through the elongate body member from a first end to a second end thereof, wherein the elongate body member comprises a slot that extends from an outer surface of the elongate body member to the channel defined thereby, the slot having side edges opposed to each other; a pair of wings extending from the elongate body member on opposite sides of the slot, the pair of wings separated from each other by an angle, wherein the wings and the slot cooperate so that when the wings are brought into contact with each other the anchor secures the catheter in the channel, wherein the pair of wings define a first suture eyelet offset from a centerline of the channel when the pair of wings are brought into contact with each other; and an additional wing extending from the elongate body member defining an additional suture eyelet offset from the centerline of the channel. - View Dependent Claims (23, 24, 25, 26)

27. A method of securing a catheter to tissue, wherein the method comprises:
-
providing an anchor comprising a body member, wherein the body member comprises a flexible material defining at least one opening through the body member; inserting a non-flexible portion of a catheter anchor placement tool into the at least one opening of the anchor, wherein the anchor is held thereon; inserting the catheter through a lumen in the catheter placement tool; and holding the anchor and removing the catheter anchor placement tool so as to position the anchor on the catheter. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35)
