Abstract
Abstract A banding prosthesis comprising an expandable helical member encased within an elongatable outer covering. The ends of the outer covering are sealed and incorporate silk sutures for joining the two ends of the banding prosthesis to form a band about the circumference of a tubular organ such as a blood vessel so as to encircle and constrict the organ lumen. An intraluminal balloon dilator is inserted within the lumen of the organ in the region of the band and is inflated to dilate the banding prosthesis and allow the constricted lumen to expand. The design of the present invention allows for gradual dilation of the banding prosthesis in stages.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A banding prosthesis comprising an expandable helical member having a series of coils that define a cylindrical volume having an outer surface, said outer surface being encased by an elongatable outer covering having a pair of sealed ends to completely enclose the cylindrical volume of said helical member said ends of said outer covering incorporating attachment means for joining the two ends of the banding prosthesis to form an encircling band about a circumference of a tubular organ so as to constrict the organ lumen whereupon an intraluminal balloon dilator inserted within the lumen of said organ in the region of said band and inflated can be used to permanently dilate said banding prosthesis and allow the constricted lumen to expand.
Claim 2
Dependent Claim
121 words
A banding prosthesis comprising an expandable helical member having a series of coils that define a cylindrical volume having an outer surface, said outer surface being encased by an elongatable outer covering having a pair of sealed ends to completely enclose the cylindrical volume of said helical member said ends of said outer covering incorporating attachment means for joining the two ends of the banding prosthesis to form an encircling band about a circumference of a tubular organ so as to constrict the organ lumen whereupon an intraluminal balloon dilator inserted within the lumen of said organ in the region of said band and inflated can be used to permanently dilate said banding prosthesis and allow the constricted lumen to expand.
Claim 3
Dependent Claim
18 words
A banding prosthesis as claimed in claim 1 wherein said expandable helical member is made from stainless steel.
Claim 4
Dependent Claim
22 words
A banding prosthesis as claimed in claim 1 wherein said elongatable outer covering is formed from a tubular member of silicone rubber.
Claim 5
Dependent Claim
24 words
A banding prosthesis as claimed in claim 1 in which said ends of said outer covering are sealed with silicone type A medical adhesive.
Claim 6
Dependent Claim
20 words
