Abstract
A mechanism for applying a predetermined pattern of material onto an elongate tubular substrate includes a first motor, an engagement member rotatable by the first motor and configured to reversibly grasp an elongate member, such that rotation of the first motor rotates the elongate member around its longitudinal axis, a fluid dispenser configured to dispense a fluid having a first, flowable state, the fluid dispenser including an elongate dispensing conduit having a distal end having an orifice, the orifice configured to be placed adjacent a surface of the elongate member, a second motor configured to move at least one of the elongate member or the elongate dispensing conduit such that the orifice changes its relative orientation along the longitudinal axis of the elongate member, and wherein the distal end of the elongate dispensing conduit is configured to apply a bias on the surface of the elongate member.
