Latest Patents

One of Longson's latest patents is the "Microtaper needle and method of use." This invention relates to medical needles used in connection with guide wires. The needle features a substantially cylindrical tube formed along a central longitudinal axis, with a tapered tube connected to one end that has a sharpened end. A channel extends through both the cylindrical and tapered tubes, aligned with the longitudinal axis. In certain embodiments, the tapered portion is designed to be radially expandable, which occurs when a guide wire is selectively inserted through the channel. The radial expansion is facilitated by a relief on the tapered tube portion, which may include a plurality of slots that expand as the guide wire is inserted.

Another significant patent is the "Cleaning brush for medical devices." This brush is designed for in situ cleaning of one or more passageways defined by a medical device. It features a NiTiNOL shaft attached to a fill section via a proximal connector sleeve, which is resistance welded to both the fill section and the shaft. The fill section is composed of braided wire and includes bristles interwoven with the braided wire. It is attached to an atraumatic tip through a distal connector sleeve, also resistance welded. The atraumatic tip contains a NiTiNOL core wire, around which is a gold-plated tungsten coil that is visible under fluoroscopy. This design helps facilitate the cleaning of passageways while protecting both the patient and the medical device from potential trauma.
