Claim:
1. A sheath for a medical instrument, comprising: an elongate body extending from a proximal end to a distal face, the elongate body comprising a diverging element proximate the distal face; a neck region extending from the distal face; a first hollow lumen extending from a first end proximate the proximal end to a second end distal the distal face; a second lumen extending from proximate the proximal end to the distal face; a third lumen extending from the proximal end to the distal face; and a transparent window positioned at the second end of the first lumen to seal the first lumen at the second end, the transparent window being configured to transmit light therethrough; wherein each of the second lumen and the third lumen comprises a distal-most portion open at the distal face; wherein the distal face includes a single continuous surface defining an opening of the distal-most portion of the second lumen and an opening of the distal-most portion of the third lumen; and wherein the diverging element is configured to change an orientation of the openings of the second and the third lumens relative to each other upon activation of the diverging element.
