  • Patent number: 6554802
    Abstract: The present invention provides an anchor for securely positioning a catheter intended to deliver drug or other medicaments to a desired position in tissue wherever found in the body or in epidural or intrathecal space of a spinal cord or brain. The present invention comprises, in the preferred embodiment, a generally tubular body for receiving the catheter and a pair of wings to assist in securing the device. The body has a slot that extends through the body between the wings. The wings and the slot cooperate so that the opposed edges of the slot just come together as the wings are brought into contact with each other. The wings interact with the slot to radially compress the catheter within the lumen of the tubular body to hold the catheter in a fixed relation to the tubular body. In addition, the wings allow the device to be sutured to tissue to secure and fix the device to tissue. A first suture is placed around the base of the wings very near where the wings contact the body of the anchor.
