  • Patent number: 11291755
    Abstract: Exemplary embodiments described herein are directed to arteriovenous (AV) access catheters with inline needles that are protectable by sliding displacement of the catheter, and to methods of performing hemodialysis using said AV catheters. Extension (sliding) of the catheter portion of an exemplary device relative to a needle portion, after the needle of the needle portion has been used to access a patient fistula/graft, allows the catheter to cover the needle tip, thereby minimizing or eliminating the possibility that the needle may damage the fistula/graft. Because the needle still remains largely within the catheter, there is no risk of catheter collapse, kinking, etc., which could compromise blood flow during a hemodialysis procedure.

The safety feature is a telescopic device including a shield with handling wings, which when placed in cooperating relationship, allows accommodation of a conventional unmodified blood collection needle affixed to a hub, and a sleeve with a locking cap. After use, the hub with the needle are pulled rearwardly into positive locking position which prevent the hub and needle from moving out of the shield thereafter. The telescopic nature of the device then allows the locked needle/hub to move rearward in relation to the shield until the shield is unreleasably locked to the sleeve. The shield provides for passage of the needle and hub from a releasable locked use position to a shielded and unreleasable locked protected position.

A spring is telescoped over the cannula and engages with or into distal portions of the hub. A hub guide projects radially out from the hub. A first wing includes a center sleeve rotationally mounted on the hub and axially movable along the hub when a slot formed in the center sleeve aligns with the hub guide. A second wing has proximal and distal sleeves mounted at opposite ends of the center sleeve. The proximal and distal sleeves each are rotationally mounted relative to the hub and each include slots that enable sliding movement of the hub guide when the slots of the second wing align with the slot of the first wing. The spring propels the cannula and hub into a shielding position when the slots of the wings are rotated into alignment with one another.

  • Publication number: 20040225261
    Abstract: A butterfly needle device having a passive needle protection system includes a needle that has a proximal end, a distal tip and defines a needle axis. A cylindrical base member having an axially aligned groove is disposed over the needle with a first wing extending radially from the base member. A second wing is provided for rotation about the needle axis relative to the first wing between a closed configuration in which the wings are juxtaposed and an open configuration in which the wings are displaced from each other. A cylindrical needle guard having a plug is disposed over the needle. A spring biases the needle guard distally relative to the base member. A wing-activated mechanism is provided to align the plug with the groove after a closed-open-closed wing cycle allowing the needle guard to distally advance to cover the needle tip at the end of the cycle.

    Abstract: A needle sheath assembly comprises a butterfly needle coupled to an IV tubing, and a plastic sheath comprising two rear side slits, two pairs of upper and lower snapping members, a latched member in front of the slits, a slot extended forward from the latched member. The needle is concealed in the sheath. The upper and lower snapping members secured together. In use push the wings forward along the slot until the needle projects from the aperture. After use pull the wings rearward until the needle has concealed in the sheath and a joint of the wings has moved in the slits prior to pushing the wings forward again until being stopped by the latched member. This can eliminate a possibility of accidentally pricking a medical worker after use. Also, criminals are prevented from selling needle sheath assemblies to hospitals again by simply cleaning or even disinfecting the used needles.

  • Patent number: 6579267
    Abstract: System for the subcutaneous delivery into the body of a patient of a fluid from a remote vessel. The system includes a main assembly and placement member with a needle. A delivery tube for carrying the fluid is attached at a near end to the remote reservoir or vessel. At removed end, the delivery tube has a needle for engagement with the main assembly. The main assembly includes a rotating member that when the rotating is perpendicular to the main assembly, it will accept the handle and needle for emplacement of the body onto a patient. After the handle and needle are removed, the delivery tube can be attached to the rotating member which can then be rotated down to a position along to and adjacent the skin of the patient. This provides for a flush mounted infusion device.

  • 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.
