Abstract
A sterilizable catheter of micro-thin diameter has a central coherent fiber bundle for carrying an image to a viewing means, which is surrounded by light fibers. The proximate end of the catheter is provided with a coupling means for aligning the coherent optical bundle with the optical system of the viewing means and for providing an interface with light transmitting means to transmit light from a light source to the body cavity. The coupling means has a diameter no bigger than the diameter of the covering of the catheter. When the catheter is used in a trochar, the trochar can be removed while the catheter remains in place. This is accomplished by removing the viewing means and sliding the trochar over the catheter and then replacing the viewing means for further viewing within the body cavity. The catheter of this invention may be provided in various sizes, each having coupling means for reception in any one of a plurality of sockets in a video monitor which are sized for the various catheters to provide an image to the video monitor screen.
