  • Patent number: 8105289
    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.

  • Publication number: 20110276002
    Abstract: In some embodiments of the invention, an access device can be provided. Advantageously, the access device can enhance the detection of the device's access into a desired body space. For example, the access device may have portions with enhanced visibility to a naked human eye, or an imaging device such as a medical imaging device. Where an imaging device is used, the imaging device can image the access device in a space that usually would not be visible to an operator, such as within a medical patient's body. Where the access device is directly viewed by a human eye, the access device can provide some form of feedback that allows an operator to more quickly discern if the access device has entered a desired space. For example, if the access device is to enter a blood-filled body space, the access device can allow blood to flow up and into the device, and the device can make the blood's presence more immediately apparent.
