Abstract: 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.

Abstract: A connector and method of connecting are described for connecting a first and second catheter at an overlap area where the first catheter fits within the second catheter. The connector includes a collar that surrounds a portion of the overlap area and a clamp that applies a radially inward force to the collar and encircles a portion of the overlap area.

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.

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.
