Publication number: 20110301542Abstract: A portal access assembly includes an inserter that has a needle, a cap moveable along the length of the needle and an infuser having a cannula through which the needle extends. A safety mechanism inside the cap allows the needle to be moved relative to the cap so long as the shaft of the needle biases against an edge of one of the legs of the mechanism. After the cannula is properly positioned in the implanted port to establish a fluid path between the port and the infuser, the needle is removed by being pulled upwards until it no longer biases the one leg of the mechanism. At which time the safety mechanism fixedly captures the needle inside the cap to prevent the contaminated tip of the needle from being exposed to the environment. At the same time, the cap is detached from the infuser.Type: ApplicationFiled: June 4, 2010Publication date: December 8, 2011Applicant: SMITHS MEDICAL MD, INC.Inventors: Lori Schwartz, Ronald G.

Publication number: 20110092921Abstract: An implantable portal includes a septum that has embedded therein an indicia adapted to identify at least one characteristic of the portal. The indicia may be formed as an impression at a base layer of the septum, and is filled with a radiopaque material. The septum base layer is covered by liquid silicone, which bonds with the septum base layer when solidified, so that an integral one-piece septum, with the identifier indicia embedded therein, is effected. The indicia embedded septum is fitted to the reservoir housing of the portal for providing identification information for that portal. The septum embedded indicia is viewable visually and also by x-ray or computer tomography imaging.Type: ApplicationFiled: October 16, 2009Publication date: April 21, 2011Applicant: SMITHS MEDICAL MD, INC.Inventors: William Lloyd Beling, Kristin Finberg, Ronald Gene Travis

Publication number: 20090264825Abstract: An infusion device including a site and a set for delivery of a substance to a patient. The site can include a cannula that is introduced into a subcutaneous layer of skin of the patient. The set can be coupled to the site by placing the set over the site and moving the set from an unlocked to a locked position. The set can be oriented at multiple rotational orientations with respect to the site, and can be coupled and uncoupled with the site multiple times. Also included is a device for inserting a subcutaneous infusion device into a subcutaneous layer of skin of a patient. Some devices automatically retract a needle used to introduce the cannula.
