Filed:

Oct 4, 2001

Appl. No.:

09/969870

Inventors:

Jeffrey D. Sandstrom - Forest Lake MN
William L. Beling - Newbrighton MN
Kristin Finberg - Minneapolis MN
Ronald G. Travis - Spring Lake Park MN

Assignee:

Deltec, Inc. - St. Paul MN

International Classification:

A61M 500

US Classification:

604110, 604117, 604233, 604239, 604272

Abstract:

A right angle safety needle has a base to which an arm is hingedly mounted at a proximal portion. The base has an opening at its distal portion wherethrough the vertical portion of the right angle needle extends. A well is formed adjacent the opening and a dam is provided on the side of the well away from the opening. To retract the needle from the opening, the horizontal portion of the needle, which may be encased in an arm, is rotated about the upright to which it is hingedly connected so that the needle is pivoted upwards and withdrawn from the opening. Once the tip of the needle clears the opening, due to the tip of the needle being offset from the body of the needle and the fact that the needle tends to flex forward, the tip of the needle is entrapped in the well adjacent to the opening. The dam forward of the well provides a backstop for any further forward movement of the tip of the needle, thereby fixedly retaining the needle within the well. Stops are provided in the device, at its arm and base, to prevent the needle from being further moved relative to the base once the tip of the needle is entrapped in the well of the base.

International Classification:

A61M 31/00

US Classification:

604110, 604 9301

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. The bore is defined between an opening at the underside of the base and an opening at the upper surface of the base.

International Classification:

A61M 5/178

US Classification:

60416408, 60416407

Abstract:

A needle protector that protects the tip or distal end of a cannula, a trocar, or a cannula/trocar combination, is provided by an extruded tubing that has at least a section thereof that includes one or a plurality of protrusions or protuberances that are configured in a given fashion so that there is a slight bend created at that section of the tube, when the tube is fitted onto a cannula or trocar with the protrusions coming into contact with the outer diameter surface of the cannula or trocar. This results in friction contact between the protrusions and the cannula or trocar to maintain the tube protector in place relative to the cannula or trocar. The protrusions may be punched or lanced in the tube to a given depth towards the interior of the tube to establish a given friction contact.

International Classification:

A61M 37/00

US Classification:

60428802

Abstract:

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.
