Abstract
Abstract A mandrel for use with a catheter or body probe comprises at least four outer wires which are spirally wound with a high pitch around a straight wire core. The outer wires are covered by a coating of plastic of uniform thickness wherein the coating is sufficiently thin so that the contours of the outer wires are preserved on the outer side of the mandrel. Each turn of the outer wires has a large component in longitudinal direction, and the mandrel is easily displaceable within the catheter.
