Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
120 words
A method for adhesively coating the inner surface of an external catheter having a sheath of thin, stretchable, elastic material, said sheath having a generally cylindrical section merging at one end with a tapered neck section terminating in an outlet section of reduced diameter, comprising the steps of inserting the neck and outlet sections of said sheath axially into one end of a relatively rigid open-ended tube and then folding said cylindrical section back along the outer surface of said tube to support said cylindrical section in stretched condition with its inner surface in everted and exposed condition, and then applying a layer of pressure-sensitive adhesive to the exposed inner surface of the everted cylindrical section supported by said tube.
Claim 2
Independent Claim
120 words
A method for adhesively coating the inner surface of an external catheter having a sheath of thin, stretchable, elastic material, said sheath having a generally cylindrical section merging at one end with a tapered neck section terminating in an outlet section of reduced diameter, comprising the steps of inserting the neck and outlet sections of said sheath axially into one end of a relatively rigid open-ended tube and then folding said cylindrical section back along the outer surface of said tube to support said cylindrical section in stretched condition with its inner surface in everted and exposed condition, and then applying a layer of pressure-sensitive adhesive to the exposed inner surface of the everted cylindrical section supported by said tube.
Claim 3
Dependent Claim
18 words
The method of claim 1 in which said tube is supported upon a mandrel during said applying step.
Claim 4
Dependent Claim
33 words
The method of claim 1 in which said layer of pressure-sensitive adhesive is applied circumferentially about said cylindrical section in a band having a width narrower than the length of said cylindrical section.
Claim 5
Independent Claim
25 words
The method of claims 1 or 3 in which there is the step of covering said layer of pressure-sensitive adhesive with a removable release, strip.
Claim 6
Dependent Claim
24 words
The method of claim 4 in which said removable release strip and said layer of pressure-sensitive adhesive are simultaneously applied to said cylindrical section.
Claim 7
Dependent Claim
24 words
The method of claim 5 in which said release strip constitutes a carrier strip for applying said pressure-sensitive adhesive layer to said cylindrical section.
