Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
61 words
A novel method for the application of an orthopedic device to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 2
Dependent Claim
61 words
A novel method for the application of an orthopedic device to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 3
Independent Claim
63 words
A method for the application of an orthopedic device to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 4
Independent Claim
63 words
A method for the application of an orthopedic device to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 5
Dependent Claim
66 words
A novel method for the application of an orthopedic cast to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable polyester resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said polyester resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 6
Dependent Claim
66 words
A novel method for the application of an orthopedic cast to a body member which comprises enclosing said member in an essentially dry ultrasonic energy curable polyester resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said polyester resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous device.
Claim 7
Dependent Claim
68 words
A novel method for the application of an orthopedic cast to a body member which comprises wrapping said member in a long strip of an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous cast.
Claim 8
Dependent Claim
68 words
A novel method for the application of an orthopedic cast to a body member which comprises wrapping said member in a long strip of an essentially dry ultrasonic energy curable resin system impregnated, flexible fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous cast.
Claim 9
Dependent Claim
69 words
A novel method for the application of an orthopedic cast to a body member which comprises wrapping said member in a long strip of an essentially dry ultrasonic energy curable resin system impregnated, flexible glass fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous cast.
Claim 10
Dependent Claim
69 words
A novel method for the application of an orthopedic cast to a body member which comprises wrapping said member in a long strip of an essentially dry ultrasonic energy curable resin system impregnated, flexible glass fabric, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy; and curing said resin at room temperature by exposure to ultrasonic energy to form a hard, lightweight, physiologically inert integral porous cast.
Claim 11
Dependent Claim
21 words
The method of claim 4 wherein said body member is covered with a stockinette prior to being wrapped in said strip.
Claim 12
Dependent Claim
20 words

Claim 13
Dependent Claim
60 words
An essentially dry storage stable flexible resin-impregnated fabric adapted to wrap a body member, said fabric being in the form of a long narrow bondage strip, said resin comprising an ultrasonic energy curable resin system capable of becoming hard and rigid at room temperature upon exposure to ultrasonic energy, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy.
Claim 14
Dependent Claim
60 words
An essentially dry storage stable flexible resin-impregnated fabric adapted to wrap a body member, said fabric being in the form of a long narrow bondage strip, said resin comprising an ultrasonic energy curable resin system capable of becoming hard and rigid at room temperature upon exposure to ultrasonic energy, said system including encapsulated catalyst releaseable upon exposure to ultrasonic energy.
Claim 15
Dependent Claim
20 words
