Patent number: 8728039Abstract: An anchoring system for an elongated medical article comprises an anchor pad and a retainer mounted upon the anchor pad. The retainer includes a base, a cover, and a compressible member including a receptacle into which the medical article to be retained is placed. When the cover is closed, the medical article is secured within the receptacle by the pressure of the compressible member and the cover upon the medical article. One or more biasing members act upon the compressible member to increase the frictional forces acting on the retained section of the medical article. The receptacle may form a channel that follows a curved path through the retainer. The retainer may also include guide extensions to support the medical article along a transverse bend toward the skin of the patient.Type: GrantFiled: August 10, 2007Date of Patent: May 20, 2014Assignee: Venetec International, Inc.Inventors: Steven F.

Patent number: 8636698Abstract: An anchoring system for securing a dialysis catheter to a patient comprises an anchor pad and retainer. The anchor pad is attached to the skin of the patient by an adhesive layer on one side of the pad. The retainer is disposed upon the surface of the anchor pad opposite the adhesive layer and includes a base, a cover, and an adhesive spot. A groove upon the base is arranged to receive a Y-site portion of a dialysis catheter. A post also protrudes from the base to the cover at a position which will be disposed between the two distal branches of the dialysis catheter. The cover closes over the base, securing the Y-site between the groove and the post. Closing the cover places the catheter in contact with the adhesive spot. This contact between the retainer, adhesive spot and catheter inhibits inadvertent motion of the catheter.Type: GrantFiled: January 30, 2012Date of Patent: January 28, 2014Assignee: Venetec International, Inc.Inventors: Steven F.
