    Abstract: The device is an implantable subcutaneous injection port used for various purposes including, but not limited to, vascular access and laparoscopic adjustable gastric banding. This device, with its tubing route and flexible connectors offers a solution to the problem of tubing occlusion and loss of integrity due to kinking. This device exhibits an injection chamber disposed within a housing. A self sealing septum is disposed within an injection chamber aperture. A second aperture communicates with a tube that is designed to connect to a catheter or other device suitable to the surgical application. Here the second aperture exits directly beneath the onlay port reducing the possibility of tubing kink, needle puncture and malpositioning seen with only ports where the catheter exits from the side of the device. An alternate embodiment utilizes a u-joint and ball joint to maximize the flexibility of the connection between the onlay port and the exiting catheter.

    Abstract: The subcutaneously implantable vascular access port has two parts including a body and a wing. The body supports a chamber covered by a septum, with a septum held in place over the chamber by a collar. The chamber is coupleable to a vascular structure, such as through tubing extending from the body, for delivery of medical preparations. The body is preferably elongate in form. The wing is configured to be adjustable in width. In one embodiment the wing rotates relative to the body and has an elongate form similar to that of the body. When the wing is rotated it extends laterally from the body and enhances a stability of the body. In another embodiment, the wing is provided as a deformable wing which can expand laterally out of side openings of a cavern in the body into which the deformable wing is inserted.

  • Patent number: 8870829
    Abstract: Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

  • Patent number: 8852160
    Abstract: A venous access port assembly having a housing base, a flange, and a septum. The housing base defines an interior reservoir. The flange includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the flange from a top surface to a bottom surface of the flange. According to one aspect, the flange may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material of the flange, or they may be formed by voids in the X-ray discernable material. According to another aspect, the flange may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the flange applied with the radiopaque agent.

  • Publication number: 20140276473
    Abstract: An implantable portal includes a septum that has embedded therein a plurality of formations that together form an indicia adapted to identify at least one characteristic of the portal. The formations are configured from impressions formed on different layers of the septum spatially separated along the vertical axis of the septum. The impressions are filled with a radiopaque material. The superposed formations do not overlap when viewed from atop the septum. When viewed under radiographic imaging from the top of the septum, a 3-D identification indicia is presented to the viewer. The 3-D indicia may be used as a 3-D marker to focus the location of the septum where a needle to access the fluid reservoir of the portal may be inserted.

  • Publication number: 20140207116
    Abstract: This improved subcutaneous implantable vascular access port invention is designed to accommodate a larger catheter caliber attachment and six multi-window elongated dual lumen trough reservoir to allow 200-600 milliliters per minute of blood flow. This accommodating high flow fluid volume blood flow rate will be ideal to support functions to include but not limited to dialysis and electrophoresis. Both the six multi-window non-coring needle access septum and subcutaneous implantation of this high flow vascular access port will markedly reduce the risk of infection. The augmented port length trough style and six self-sealing multi septum windows will allow variable needle placement on a bi-daily basis. The purpose of the variable different location needle site is to avoid both skin breakdown, and reduce the risk of infection.

  • Publication number: 20140194833
    Abstract: An access port includes a first and a second resilient element, each having a first face and a second face. A first slit and a second slit are defined in the first and second resilient elements, respectively. The first face of the first resilient element abuts the first face of the second resilient element. The lengthwise direction of the second slit is transverse to the lengthwise direction of the first slit. The first and second resilient elements are configured to assume at least a first position wherein the first and second slits are substantially closed, thereby preventing a passage of a fluid therebetween and at least a second position wherein a member projects through the first and second slits, thereby allowing the member to pass through the access port.
