Disclosed herein are techniques for the reduction speckle of a projection display system using novel lenslet integrators and related methods. The distal end of the outer sheath terminates at least one medical device length proximal of the medical device. The hydrophilic film-forming polymer is preferably GANTREZ S. 1 to 20 seconds at a time and that light from the lamp light source irradiates the object several times. The distal tip of the catheter is rendered radiopaque, at least at its distal-most end, to enable visualization of the position of the catheter and to facilitate placing the catheter in the desired position.
