| description | The present invention relates to medical needles used in connection with guide wires. A needle of the present invention includes a substantially cylindrical tube formed along a central longitudinal axis. A tapered tube is connected to one end of the tube and has a sharpened end. A channel extends through the cylindrical tube and the tapered tube, and is aligned with the longitudinal axis. In some embodiments, the tapered portion is radially expandable. For instance, radial expansion may result when a guide wire is selectively inserted through the channel. The radial expansion may be facilitated by a relief on the tapered tube portion. Optionally, the relief includes a plurality of slots which expand as a guide wire is inserted through the channel and tapered portion, thereby also causing the internal and outer diameters of the tapered portion to expand. |
