1. A feeding tube assembly comprising:
- a flexible feeding tube having opposite first and second longitudinal ends, a longitudinal axis extending between the first and second longitudinal ends, and a feeding passage defined therein extending along the longitudinal axis between the first and second longitudinal ends;
an inlet adaptor adjacent the second longitudinal end of the feeding tube in fluid communication with the feeding passage, the inlet adaptor configured for fluid connection to a source of enteral feeding liquid to fluidly connect the source of enteral feeding liquid to the feeding passage;
an imaging assembly including an imaging device, the imaging assembly configured for generating and transmitting imaging signals indicative of images of the alimentary canal of a subject, wherein the imaging assembly is secured to the feeding tube adjacent the first longitudinal end of the tube;
a feeding outlet proximate the imaging assembly and in fluid communication with the feeding passage for delivering enteral feeding liquid to the subject;
a console connector in communication with the imaging assembly for receiving the imaging signals, the console connector including a housing and configured for use in connecting the imaging assembly to a console to allow transmission of the imaging signals to the console, the feeding tube extending into the console connector;
a joining assembly separate from the housing and feeding tube and configured to connect the console connector to the feeding tube and to the inlet adaptor, wherein the housing is molded over the joining assembly, the console connector overlapping a distal end of the joining assembly.

Abstract
A catheter with an imaging assembly is disclosed. The catheter is used with a console for viewing and/or storing images obtained from the catheter. The catheter may be a feeding tube assembly. The imaging assembly on the feeding tube assembly allows a user to confirm placement of the feeding tube assembly in the patient'"'"'s alimentary canal.
