Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
111 words
Splint system for the treatment of carpal tunnel syndrome in a patient comprising: (a) a clamp formed from a generally rectangular sheet of semi-rigid material and formed into a generally tubular shape having four generally planar panels, a first two of the panels occupying the ends of the rectangular sheet, and the other two panels being located between the first two panels to give a cross-section of a diamond-shaped conformation for embracing the wrist of a patient with opposite corners embracing the wrist exteriorly of the radius and ulna bones to press them together, and (b) a bandage surrounding the clamp to regulate the pressure of the clamp on the wrist.
Claim 2
Dependent Claim
111 words
Splint system for the treatment of carpal tunnel syndrome in a patient comprising: (a) a clamp formed from a generally rectangular sheet of semi-rigid material and formed into a generally tubular shape having four generally planar panels, a first two of the panels occupying the ends of the rectangular sheet, and the other two panels being located between the first two panels to give a cross-section of a diamond-shaped conformation for embracing the wrist of a patient with opposite corners embracing the wrist exteriorly of the radius and ulna bones to press them together, and (b) a bandage surrounding the clamp to regulate the pressure of the clamp on the wrist.
Claim 3
Dependent Claim
16 words
Splint system as recited in claim 1, wherein the clamp is formed of a thermoplastic resin,
Claim 4
Dependent Claim
12 words
Splint system as recited in claim 2, wherein the resin is poly-epsilon-caprolactone.
Claim 5
Dependent Claim
51 words
Splint system as recited in claim 1, wherein the ends of the sheet are located at one corner of the diamond and are spaced from one another, and wherein the other three corners of the diamond are defined by the junction between the panels, the corners being formed with smooth curves.
Claim 6
Dependent Claim
25 words
Splint system as recited in claim 1, wherein the bandage is of a generally elongated rectangular shape with a loop-and-hook fastener located at its ends.
Claim 7
Dependent Claim
24 words
Splint system as recited in claim 1, wherein the ends are provided with outwardly-extending flares to prevent pinching when the ends are pressed together.
Claim 8
Dependent Claim
76 words
Splint system for the treatment of carpal tunnel syndrome, comprising: (a) a clamp formed of a semi-rigid material and formed into a generally tubular shape of parallelogram-shaped cross-section to give a conformation in which the clamp embraces the wrist of a patient with opposite corners embracing the wrist exteriorly of the radius and ulna bones to press them together, and (b) a bandage surrounding the clamp to regulate the pressure of the clamp on the wrist.
Claim 9
Dependent Claim
