The proposed patents relates to a catheter, tube, dilator, shunt, drain, access device like invention that allows positioning over another catheter, tube, dilator, shunt, wire, cable, drain, access device or the like via a sidewall defect in contrast to the current practice of deployment of catheters, tubes, dilators, drains, access devices or the like over a guiding device such as a wire via the openings at the tips of these devices. This unique method of deployment offers some advantages over current methodology and allows avoiding some limitations with methods in current practice that rely heavily on traditional guiding devices such as wires. Potential advantages include procedural time reduction, less labor-intensive procedures, as well as the ability to perform some objectives not possible with current methods in certain situation.
