Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
An iris clip filament prepared for attachment to an intraocular lens comprising: a rigid ferrule having a passageway extending completely therethrough; said filament extending completely through the length of said passageway with protrusion therebeyond; the portion of said filament within said passageway being in frictional contact with said ferrule along said length of said passageway; and said protrusion being beaded to a diametral size greater than an adjacent diameter of said passageway.
Claim 2
Dependent Claim
72 words
An iris clip filament prepared for attachment to an intraocular lens comprising: a rigid ferrule having a passageway extending completely therethrough; said filament extending completely through the length of said passageway with protrusion therebeyond; the portion of said filament within said passageway being in frictional contact with said ferrule along said length of said passageway; and said protrusion being beaded to a diametral size greater than an adjacent diameter of said passageway.
Claim 3
Dependent Claim
32 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 1 wherein said filament is formed of a flexible plastic material and said ferrule is formed of metal.
Claim 4
Dependent Claim
35 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 1 wherein said filament is formed of a flexible plastic material and said ferrule is formed of a rigid plastic material.
Claim 5
Dependent Claim
23 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 1 wherein said filament is compressed within said passageway.
Claim 6
Dependent Claim
22 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 1 wherein said ferrule has a ball-shaped portion.
Claim 7
Dependent Claim
37 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 5 wherein said ferrule includes a neck portion for extending the length of said passageway beyond the diametral dimension of said ball portion.
Claim 8
Dependent Claim
22 words
An iris clip filament prepared for attachment to an intraocular lens according to claim 1 wherein said ferrule is cylindrical in shape.
Claim 9
Dependent Claim
103 words
The intraocularly implantable system of a lens having an aperture and an iris clip filament anchored within said aperture wherein said system comprises: a rigid ferrule, said ferrule being secured to said lens within said aperture and having a passageway extending completely therethrough in a direction generally parallel to said lens aperture, said filament extending completely through said passageway and protruding therebeyond, the portion of said filament within said passageway being in frictional contact with said ferrule within said passageway and said protrusion of said filament being beaded to a size substantially greater than an adjacent diameter of said passageway in said ferrule.
Claim 10
Dependent Claim
103 words
The intraocularly implantable system of a lens having an aperture and an iris clip filament anchored within said aperture wherein said system comprises: a rigid ferrule, said ferrule being secured to said lens within said aperture and having a passageway extending completely therethrough in a direction generally parallel to said lens aperture, said filament extending completely through said passageway and protruding therebeyond, the portion of said filament within said passageway being in frictional contact with said ferrule within said passageway and said protrusion of said filament being beaded to a size substantially greater than an adjacent diameter of said passageway in said ferrule.
Claim 11
Dependent Claim
15 words
The intraocularly implantable system according to claim 8 wherein said ferrule has a ball-shaped portion.
Claim 12
Dependent Claim
14 words
The intraocularly implantable system of claim 8 wherein said ferrule is of cylindrical shape.
