US 9,307,893 B2 · Space-optimized visualization catheter with camera train holder in a catheter with off-centered lumens

Abstract

Methods and apparatuses for space-optimized visualization catheters are provided. Some embodiments utilize complimentary metal-oxide-semi-conductor (“CMOS”) technology integrated into a CMOS camera train holder system that may be a stand-alone component for use with a visualization catheter, such as a baby endoscope, or may be fabricated/extruded as a part of the catheter itself. Some embodiments of apparatuses, methods, and equivalents thereto provide better direct visual feedback to the medical personnel performing the procedure while providing a similarly-sized outer diameter visualization catheter device having an increased space therein for additional lumens and equipment or by reducing the overall outer diameter of the visualization catheter.

Dependent claims

A visualization catheter comprising:

a camera train holder holding a camera train comprising a visualization sensor and a lens stack;
and
a catheter comprising:
a proximal catheter portion;
a distal catheter portion;
a working channel lumen extending through the proximal catheter portion and the distal catheter portion;
a cabling lumen extending through the proximal catheter portion and the distal catheter portion and adjacent to the working channel lumen, wherein the cabling lumen is configured to have disposed therein cabling that is electrically coupled to the visualization sensor at a distal end of the cabling lumen;
and
a notch having disposed therein the camera train holder, wherein the notch is disposed into an inner surface of the distal catheter portion, and wherein the notch is positioned distal the distal end of the cabling lumen and axially off-centered from a central longitudinal axis of the cabling lumen at the distal end of the cabling lumen.
