Abstract
Abstract A photographic capsule for diagnostic use in photographing a walled organ of the body such as a portion of the alimentary canal or the like includes a frame with a photographic unit and a balloon surrounding the photographic unit for expansion in place in the alimentary canal to smooth and space to a focal plane the walls of the portion to be photographed; the photographic unit making exposures through the balloon, illuminated by light relayed from outside the subject against a conical mirror through a fibre optics bundle within a shielding tube which also serves for retrieval, for holding signal leads, and as conduit for gas in inflating and deflating the balloon; in a preferred embodiment an electro-optical shutter is employed and a 360° view is provided by means of annular coaxial structure of photographic lens, shutter, film and balloon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
116 words
In a capsule for photographic use in a walled organ of the living human body and including a source of illumination, film and photographic focussing means, and means for retrieving the capsule from within the living human body, the improvement comprising: a frame, a balloon having attachment to the frame, means for inflating the balloon to press outward against the walls of said organ, means for photographing with one exposure a 360 degree field of view of the walls of said organ through the balloon, including the frame mounting the film and photographic focussing means within the balloon, a shutter, and said shutter coaxially mounted to the frame between the film and the photographic focussing means.
Claim 2
Dependent Claim
116 words
In a capsule for photographic use in a walled organ of the living human body and including a source of illumination, film and photographic focussing means, and means for retrieving the capsule from within the living human body, the improvement comprising: a frame, a balloon having attachment to the frame, means for inflating the balloon to press outward against the walls of said organ, means for photographing with one exposure a 360 degree field of view of the walls of said organ through the balloon, including the frame mounting the film and photographic focussing means within the balloon, a shutter, and said shutter coaxially mounted to the frame between the film and the photographic focussing means.
Claim 3
Dependent Claim
15 words
In a capsule as recited in claim 1, the shutter being a liquid crystal shutter.
Claim 4
Dependent Claim
327 words
In a capsule for photographic use in a walled organ of the living human body and including a source of illumination, film and photographic focussing means, and means for retrieving the capsule from within the living human body the improvement comprising: a frame, a balloon having attachment to the frame, means for inflating the balloon to press outward against the walls of said organ, means for photographing the walls of said organ through the balloon, including the frame mounting the film and photographic focussing means within the balloon with the photographic focussing means in an outward position relative to the film, the balloon wall being of a thickness and composition rendering at least a portion thereof substantially transparent to visible radiation on inflation, the frame having a tubular shape and the balloon attachment comprising affixation substantially coaxially thereover, the source of illumination including means for projecting light along the interior of the frame, means passing said light from the interior of the frame through the balloon at a position outward relative to the photographic focussing means, means exterior of the frame for controlling the source of illumination, the means for retrieving including means for controlling inflation and deflation of the balloon from a position sufficiently remote from the balloon to be outside a human body when the balloon is in a said walled organ of a said human body and comprising a flexible tube having communication with the interior of the balloon and means for detachable attachment to a source of compressed fluid, thereby comprising said means for controlling inflation and deflation, said means exterior of the frame including switching means for the source of illumination, fibre optics extending with said flexible tube to the frame from adjacent the source of illumination comprising said means for projecting, the means passing said light including the frame having a concentric transparent light-passing portion, and the means passing said light further including conical optical element reflecting means within the frame.
