Abstract: A medical device includes a flexible member having a hollow cavity extending between a proximal end and a distal end, an optical fiber extending through the hollow cavity, and a potting material to secure/pot the optical fiber to the distal end to inhibit damage of the distal end. The potting material can be an adhesive, such as a UV curable adhesive or dual-cure adhesive. The medical device can be stripped or a buffered optical fiber, and can include a spacer, wherein the optical fiber can be fused to the spacer, and potted in the distal end. The medical device can have a rebuffer heat shrink tube surrounding the area of the optical fiber on a guidewire, and can have distal optics at the distal end that include at least a spacer, a lens and a reflector. The medical device can be a disposable catheter, and an MMOCT catheter.

Abstract: An imaging catheter assembly comprising a catheter comprising: a proximal end; a distal end; a tubular body extending from the proximal end to the distal end; and an imaging element within the tubular body; a sheath comprising: a proximal end; a distal end; and a tubular body extending from the proximal end to the distal end, the tubular body having an inner surface, wherein the inner surface of the tubular body of the sheath at least partially defines a conduit for conveying a fluid to the distal end of the sheath, and wherein the sheath is movable such that the distal end of the sheath is positionable relative to the distal end of the catheter.

Abstract: Exemplary probes including longitudinal marker elements arranged parallel to the probe axis are provided for reducing or eliminating non-uniform rotational distortions (NURD) in imaging systems. Additional ring marker elements may also be provided to reduce or eliminate non-uniform linear distortion (NULD). These probes, as well as systems and methods of use provide for images having better image quality and reduced NURD.
