  • Patent number: 7549976
    Abstract: A portal access device that is adapted to provide long term access to a port implanted in a patient has two major components, an infuser assembly and a safety needle insertion device. The infuser assembly has an infuser housing that can be configured into a specific shape, for example a dome. A blunt cannula is attached to and extends downwardly from the underside of the infuser housing. Also connected to the infuser housing, preferably at a side thereof, is a tubing or catheter. The safety needle inserter assembly has a base having a proximal portion that is configured to form fit over the infuser housing. At the distal portion of the base uprights are provided so that a second end of an arm, to which first end a needle or a sharp cannula is connected, may be movably and hingedly connected to the base. The sharp cannula extends from the underside of the proximal end of the arm and passes through the base by way of a bore formed at the proximal portion of the base.

  • Patent number: 6332877
    Abstract: A catheter or ostomy tube placement tip is comprised of a tapered, substantially conical head portion and a cylindrical body or stem portion centrally attached to the base thereof. The cylindrical base fits snugly within the lumen of a catheter or ostomy tube such as a ostomy or jejunal feeding tube and its tapered design allows for the insertion and placement of the tube within the lumen of the stomach or other body cavity through an opening or ostomy. Once properly placed, the tip is discharged from the end of the tube so that it is dissolved by human body fluids and is excreted.

  • Patent number: 6039714
    Abstract: The present invention is an improved ostomy fluid tube and method for its use comprising a collapsible retention bolster for securing the tube to the inner stomach wall and fascia. The retention means comprise several resilient leaf or petal-shaped flanges circumferentially arranged about the feeding tube at a distal point thereon. The otherwise flat, circumferentially arranged flanges possess notches or grooves which facilitate collapse or folding of the retention means for easier removal through an ostomy or other internal cavity.

  • Patent number: 5634907
    Abstract: An infusion apparatus includes a pump and a fluid delivery set. The infusion apparatus is adapted to monitor the fluid delivery set for insuring proper placement in relation to the pump. The infusion apparatus further includes a sensor which operates to detect the proper alignment of the fluid delivery set and also the proper operating position of the infusion apparatus. The infusion apparatus includes a cover which is adapted to be in a closed position when the infusion apparatus is in proper operating position. The cover operates to secure the fluid delivery set within the mounted position in the infusion apparatus.

  • Patent number: 5628753
    Abstract: A gastrostomy feeding tube removal device is comprised of a hollow cylindrical body, a conical head formed at one end and preferably a cap or top at the other to assist in grasping the tool during use. A sheath covers the remaining body portion and is slideably moveable thereon. In use, the gastrostomy tube is pulled through the device which enters the stomach through an ostomy of the patient. Upon contacting the retention bolster means proximate the inner stomach lining, the plastic sheath is pressed forward against the extended members of the retention means thereby collapsing them and withdrawing them into the sheath. The device is then withdrawn from the patient's body simultaneously removing the tube as well.

  • Patent number: 5259367
    Abstract: Method for placing a guide wire through a gastrostomy tube which has a plug through which only the guide wire can pass in slidable communication. The plug prevents air from escaping from the stomach, thus, preventing the collapse of the stomach during the guide wire placement. The plug may comprise a substantially cylindrical member having a longitudinal bore for receiving the guide wire in slidable communication.
