  • Patent number: 6436073
    Abstract: A butterfly anchor for an infusion set is described. The anchor provides a means to rapidly and securely stabilize an intravascular catheter for a patient while preventing the catheter from resting against or puncturing the vein wall subsequent to insertion or during later patient movement. The anchor includes a flexible anchor pad having an upper surface and a lower surface. The lower surface includes a means for attaching the anchor pad to the backing pad of a butterfly infusion set and to the skin of a patient. The anchor pad includes longitudinal reinforcing means located parallel to the long axis of the catheter and spaced apart from the center line of the anchor pad so as to control the orientation of the catheter in the patient's vein.

  • Patent number: 6436091
    Abstract: Implantable devices and osmotic pump and catheter systems for delivering a pharmaceutical agent to a patient at selectable rates include an impermeable pump housing and a moveable partition disposed within the housing, the partition dividing the housing into an osmotic driving compartment having an open end and a pharmaceutical agent compartment having a delivery orifice. A plurality of semi permeable membranes may be disposed in the open end of the osmotic driving compartment and a number of impermeable barriers may seal selected ones of the plurality of semi permeable membranes from the patient until breached. Breaching one or more of the impermeable barriers increases the surface area of semi permeable membrane exposed to the patient and controllably increases the delivery rate of the pharmaceutical agent through the delivery orifice and catheter.

  • Patent number: 6406456
    Abstract: An injector for the intra-muscular, subcutaneous, or intra-dermal delivery of a fluid medicament to a patient includes a cylindrical member which has a closed end and an open end, and which is formed with a compartment between these two ends. An injection tube extends from the closed end through the cylindrical member and into the compartment. A suction pump is connected in fluid communication with the compartment to create a partial vacuum in the compartment when the open end of the cylindrical member is held against the skin of the patient. Due to this vacuum, skin of the patient is drawn into the compartment to position the tip of the injection tube against the skin. Also, skin that is adjacent the tip is drawn by the vacuum into the compartment. This stabilizes the skin around the injection tube tip and thereby minimizes any movement of skin relative to the tip during an injection of fluid medicament into the patient.
