Abstract
Abstract A high elastic modulus, cohesive bandage comprising partially extended spaced aligned elastic yarns sealed between two thin nonwoven fibrous webs by means of a polymeric binder is disclosed. The bandage provides joint support without imposing undue constriction. A method of supporting and/or providing compressive force to a mammalian limb including supporting suspensory ligaments and flexor tendons in the leg of a horse is also described.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A cohesive bandage comprising a series of spaced elastic yarns between coextensive thin non-woven fibrous cover webs, the bandage being uniformly impregnated throughout and bonded together in a unified structure with a polymeric binder having a basis weight at least equal to the basis weight of the cover webs, said yarns being maintained under tension in said unified structure,and wherein said elastic yarns are from about 550 to about 1700 denier and are uniformly spaced at about 15 to 25 yarns per inch of width with the proviso that the product of the denier times the number of yarns per inch of width is from about 10,000 to about 25,000; said cohesive bandage being further characterized by the ratio of the elastic modulus F 125 value to the elastic modulus F 50 value being less than about 10.
Claim 2
Dependent Claim
138 words
A cohesive bandage comprising a series of spaced elastic yarns between coextensive thin non-woven fibrous cover webs, the bandage being uniformly impregnated throughout and bonded together in a unified structure with a polymeric binder having a basis weight at least equal to the basis weight of the cover webs, said yarns being maintained under tension in said unified structure,and wherein said elastic yarns are from about 550 to about 1700 denier and are uniformly spaced at about 15 to 25 yarns per inch of width with the proviso that the product of the denier times the number of yarns per inch of width is from about 10,000 to about 25,000; said cohesive bandage being further characterized by the ratio of the elastic modulus F 125 value to the elastic modulus F 50 value being less than about 10.
Claim 3
Dependent Claim
15 words
The bandage of claim 1 wherein said elastic yarn is about 600 to 1,000 denier.
Claim 4
Dependent Claim
22 words
The bandage of claim 1 wherein said elastic yarn is uniformly spaced at about 17 to 22 yarns per inch of width.
Claim 5
Dependent Claim
25 words

Claim 9
Dependent Claim
27 words
The bandage of claim 1 wherein the ratio of the elastic modulus F 125 value to the elastic modulus F 50 value is less than about 5.
Claim 10
Dependent Claim
