Abstract
A needle guide ensures that an angiographic needle is inserted into a patient's femoral artery at a prescribed location, angle and direction. The needle guide includes an elongated base having a recess on one end defined by a pair of projecting fingers, and a support member on the upper surface of the base adjacent to the recess. The support member has a support surface which is inclined at a prescribed angle with respect to a locating plane defined by the base. The length of the projecting fingers help position the support surface at a spaced distance from the patient's inguinal crease, while a channel in the support surface cradles and guides the angiographic needle at the prescribed angle as it is inserted into the femoral artery. The needle guide may include a second recess defined by a pair of projecting fingers at the opposite end of the base and another support member adjacent thereto. This other support member may have a support surface inclined at an angle relative to the locating plane of the base which is different from the angle the first support member makes with the locating plane of the base. Thus, depending upon the direction in which it is oriented, the needle guide may be used to insert a needle at one of two different angles.
