Abstract
Abstract A pad for cooling the heart or other similar organs during surgery comprises a pad of a generally flat configuration constructed of a pliable material having heat transfer means in the form of a conduit for conducting a coolant through the pad adjacent one surface and an insulating device in the form of an air chamber insulating the cooling apparatus from the opposite face of the pad and including a malleable frame within the pad for maintaining the pad in selected configurations for folding around an organ, and retaining the pad in position.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
129 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, insulating means disposed between said heat transfer means and said insulating face for insulating said insulating face from said heat transfer medium, and malleable means comprising a frame of malleable metal within said pad extending substantially throughout said body substantially parallel to said heat transfer face and being sufficiently deformable to be readily formed into selected shapes and being sufficiently resistant to deformation for retaining said pad in said selected shape.
Claim 2
Independent Claim
129 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, insulating means disposed between said heat transfer means and said insulating face for insulating said insulating face from said heat transfer medium, and malleable means comprising a frame of malleable metal within said pad extending substantially throughout said body substantially parallel to said heat transfer face and being sufficiently deformable to be readily formed into selected shapes and being sufficiently resistant to deformation for retaining said pad in said selected shape.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1, wherein said heat transfer means comprises a fluid conducting passage disposed in said body closely adjacent the heat transfer face.
Claim 4
Dependent Claim
37 words
The apparatus of claim 2, wherein said fluid conducting passage enters said pad at one end and exits at the other end and passes back and forth along a plurality of parallel lines between the sides thereof.
Claim 5
Independent Claim
109 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, insulating means comprising an air space disposed between said heat transfer means and said insulating face for insulating said face from said heat transfer medium, and malleable means within said pad for permitting said pad to be readily formed into selected shapes and for retaining said pad in said selected shape.
Claim 6
Independent Claim
109 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, insulating means comprising an air space disposed between said heat transfer means and said insulating face for insulating said face from said heat transfer medium, and malleable means within said pad for permitting said pad to be readily formed into selected shapes and for retaining said pad in said selected shape.
Claim 7
Dependent Claim
12 words
The apparatus of claim 4, wherein said material is a sterilizable plastic.
Claim 8
Dependent Claim
27 words
The apparatus of claim 1, wherein said frame comprises a central spine and a plurality of cross bars defining arms extending outward from said central body member.
Claim 9
Dependent Claim
27 words
The apparatus of claim 6, wherein said heat transfer means comprises a plurality of fluid conducting passages disposed in said body closely adjacent the heat transfer face.
Claim 10
Independent Claim
124 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, an air space disposed between said heat transfer means and said insulating face for insulating said insulating face from said heat transfer medium, and malleable means within said pad for a frame of malleable metal extending substantially through said body substantially parallel to said heat transfer face permitting said pad to be readily formed into selected shapes and for retaining said pad in said selected shape.
Claim 11
Independent Claim
124 words
An apparatus for inducing local temperature changes in a portion of the body comprising: a pad of a generally flat configuration constructed of a pliable material and having a heat transfer face and an insulating face, heat transfer means closely adjacent said heat transfer face for transferring heat between a heat conducting medium and said heat transfer face, an air space disposed between said heat transfer means and said insulating face for insulating said insulating face from said heat transfer medium, and malleable means within said pad for a frame of malleable metal extending substantially through said body substantially parallel to said heat transfer face permitting said pad to be readily formed into selected shapes and for retaining said pad in said selected shape.
Claim 12
Dependent Claim
12 words
