Dialysis catheter anchoring system
First Claim
1. An anchoring system for a medical article comprising:
- a medical article having an elongated body and a branching site at which point the elongated body separates into two elongated sections, a portion of the medical article located proximal to the branching site having a cross-sectional shape;
a retainer defining a channel and an abutment surface, the channel being configured to receive at least the branching site of the medical article, the channel having a first opening, a second opening, and a third opening, the first opening being sized at least as large as the cross-sectional shape of the proximal portion of the medical article, the second opening being configured to accept one of the two elongated sections, and the abutment surface being located between the second and third openings when the branching site is located within the channel; and
an adhesive spot disposed on the retainer at a location to cooperate with the medical article to provide an adhesive force so as to resist movement of the medical article relative to the retainer in at least a direction that is generally normal to a surface of the adhesive spot.

Abstract
An anchoring system for securing a dialysis catheter to a patient comprises an anchor pad and a 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 and a cover and a adhesive spot. A groove upon the base is arranged to receive a Y-site portion of a dialysis catheter where the lumens merge distal to the insertion site. 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 also places at least a portion of the catheter in contact with the adhesive spot. This contact between the retainer, adhesive spot and catheter thereby inhibits inadvertent motion of the catheter upon the patient. A latch mechanism is disposed upon the retainer to maintain the cover in a closed position over the Y-site of the catheter on the base.
