Abstract
An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient'"'"'s skin and supports a retainer. The retainer releasably receives a portion of the catheter and includes one or more retention mechanisms. The retention mechanisms inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. In one mode, the retention mechanism is positioned within a channel of the retainer and includes at least first and second members that project from opposite sides of the channel. The members are arranged to cooperate with one another when the cover is closed so as to capture a structural portion of the catheter between the first and second members without substantially occluding an inner lumen of the catheter.
