SPACE-OPTIMIZED VISUALIZATION CATHETER WITH CAMERA TRAIN HOLDER IN A CATHETER WITH OFF-CENTERED LUMENS
First Claim
1. A visualization catheter comprising:
- 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; and
a notch disposed into an inner surface of the distal catheter portion, wherein the notch is off-centered from the cabling lumen and connected to the cabling lumen;
a camera train holder comprising;
a proximal camera train holder portion configured to receive a visualization sensor; and
a distal camera train holder portion configured to receive a lens stack;
wherein the camera train holder is disposed within the notch of the catheter.

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.
