Abstract
A catheter anchor for holding a catheter in position in a patient has a base in the form of a disc with a flat surface normal to a central axis. There is a transverse, resilient bar extending across the disc on the side opposite the flat surface. The bar has at least one reentrant groove in it to receive and grasp the catheter. There may be an additional reentrant groove in the bar expandable by a plug to constrict the catheter groove. Also, there may be a pawl sheet adapted to grip the catheter and abut the bar to inhibit unwanted insertion of the catheter into the patient. From the flat surface of the disc a number of needles extend approximately helically and symmetrically with the axis and with their exposed points engageable with the patient'"'"'s tissue by rotation. There may also be a central guide needle extending from the flat surface along the axis.
