Filed:

Aug 3, 2000

Appl. No.:

09/630582

Inventors:

Steven F. Bierman - Del Mar CA
Richard A. Pluth - San Diego CA
Wayne T. Mitchell - Cardiff CA

Assignee:

Venetec International, Inc. - San Diego CA

International Classification:

A61M 532

US Classification:

604174, 604180, 128DIG 26

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.

International Classification:

A61M 532

US Classification:

604174, 604180, 128DIG 26

Abstract:

An anchoring system includes a simply-structured device which permits a portion of a catheter or similar medical article to be easily anchored to a patient, desirably without the use of tape or needles and suture. An anchoring system for an elongated medical article comprises an anchor pad and a retainer mounted upon the anchor pad. The retainer includes a channel into which the medical article to be retained is placed. The retainer is attached to an anchor pad including an adhesive bottom surface, which can be attached to the patients skin. A medical article is secured within a channel by retaining at least one radially extending member on the medical article.

International Classification:

A61M 532

US Classification:

604180, 128DIG 26, 604174

Abstract:

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.

International Classification:

A61M 532

US Classification:

604174, 604178, 604180

Abstract:

An anchoring system includes a simply-structured device that permits a portion of a catheter tube or similar medical article to be easily anchored to a patient, desirably without the use of tape or needles and suturing. A unitary retainer desirably includes a base connected to a cover assembly by way of flexible hinges. The retainer is attached to a flexible anchor pad including an adhesive bottom surface, which can be attached to the patients skin. A catheter is secured within a channel formed between posts of the retainer. The cover assembly is reproducibly positioned over the base by bending the flexible hinges, and the cover assembly is latched to the base. The posts provide a universal feature such that the anchoring system can adapt to and receive a variety of catheters and catheter fittings by providing at least one post that is movable relative to at least one other post.

Venetec International, Inc. - San Diego CA

International Classification:

A61M 532

US Classification:

604174, 604180, 128877

Abstract:

A method of securing a medical article to the body of a patient is disclosed in which an anchoring device comprising an anchor and a retainer is used. The retainer is attached to an upper surface of the anchor and comprises a base, a cover and a post. The base is disposed on the upper surface of the anchor and the cover is connected to the base so as to move between an open and a closed position. When the cover is in the closed position, it lies above at least part of the base. The post is attached movably to either the base or the cover and is arranged so as to lie at least partially between the cover and the base when the cover is in the closed position. When securing a medical article, the cover is placed in the open position and the medical article placed onto the retainer. The cover may then be closed over the medical article and the anchoring device attached to the patient.
