Abstract: A flexible pipe features an open end and a generally closed end. The open end is elevated so that it is maintained above the remaining portion of the flexible pipe. The generally closed end of the pipe features a venting arrangement. As a result, the flexible pipe may be filled with fluid. The open end of the flexible pipe is flared and features dividers so that the ends of guidewires placed within the flexible pipe are separated. The flexible pipe features a cross section that prevents the guidewires stored therein from interacting with one another. The flexible pipe may be held in a coiled configuration by clamps. Alternatively, the flexible pipe may be straightened and attached to a surface, such as the sterile drapes covering a patient, by way of one or more wire/catheter guides which include channels positioned upon a base which features adhesive. A wire gutter serves as a bridge between the flexible pipe and the patient and features adhesive so that is may be attached to the drapes covering the patient.
