Abstract
Abstract An intrauterine contraceptive device and method of manufacturing the same including a separately formed elongate body member including a lower body portion and an upper, reduced diameter body portion and a separately formed transversal member removably affixed to the upper end of the reduced diameter body portion. Prior to affixing the transversal member on the body member, a copper helical member is located over the reduced diameter body portion. A connecting member may be provided on the transversal member to facilitate connection thereof to the body member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
75 words
An intrauterine contraceptive device comprising: an elongated body member; a spiral member formed of copper disposed around said body member; a transversal member connected at its substantial midpoint to one end of said elongated body member by connecting means; and means for connecting said transversal member to said one end of said elongated body member, said connecting means comprising means for detachably connecting said transversal member to said one end of said elongated body member.
Claim 2
Dependent Claim
75 words
An intrauterine contraceptive device comprising: an elongated body member; a spiral member formed of copper disposed around said body member; a transversal member connected at its substantial midpoint to one end of said elongated body member by connecting means; and means for connecting said transversal member to said one end of said elongated body member, said connecting means comprising means for detachably connecting said transversal member to said one end of said elongated body member.
Claim 3
Dependent Claim
32 words
A device as recited in claim 1 wherein said connecting means comprises a bore formed in said transversal member and an annular groove formed at said one end of said body member.
Claim 4
Dependent Claim
20 words
A device as recited in claim 2 wherein said bore tapers downwardly and said annular groove is correspondingly tapered downwardly.
Claim 5
Dependent Claim
53 words
A device as recited in claim 1 wherein said elongated body member comprises a lower, first elongated cylindrical portion distal from said transversal member and an upper second elongated reduced diameter cylindrical portion proximate to said transversal member and wherein said spiral member is located around said second upper reduced diameter body portion.
Claim 6
Dependent Claim
71 words
A device as recited in claim 1 wherein said transversal member includes a pair of integral leg portions defining a substantially V-shaped portion and an elongate connecting member having opposed ends, each end being integrally formed with one of said leg portions, said connecting member and upper portions of said leg portions defining a triangular space therebetween, said elongated body portion being connected at said one end to said connecting member.
Claim 7
Dependent Claim
32 words
A device as recited in claim 5 wherein said connecting means comprises a bore formed in said connecting member and an annular groove formed in said one end of said body member.
Claim 8
Independent Claim
94 words
A method of manufacturing intrauterine contraceptive devices comprising an elongate body portion, a spiral member formed of copper and a transversal portion connected at its midpoint to one end of said body portion comprising the steps of: forming a plurality of separate transversal members; forming a plurality of separate elongated body members; forming a plurality of separate copper spiral members; locating each of said separate copper spiral members around a respective separate body member; and attaching each of said separate transversal members at its midpoint to said one end of said separate body member.
Claim 9
Independent Claim
94 words
A method of manufacturing intrauterine contraceptive devices comprising an elongate body portion, a spiral member formed of copper and a transversal portion connected at its midpoint to one end of said body portion comprising the steps of: forming a plurality of separate transversal members; forming a plurality of separate elongated body members; forming a plurality of separate copper spiral members; locating each of said separate copper spiral members around a respective separate body member; and attaching each of said separate transversal members at its midpoint to said one end of said separate body member.
Claim 10
Dependent Claim
62 words
A method as recited in claim 7 wherein said transversal member has a bore formed therethrough and said body member has an annular groove formed at said one end and having a diameter corresponding to the diameter of said bore, wherein said step of attaching comprises removably attaching said transversal member to said body portion by locating said groove within said bore.
Claim 11
Dependent Claim
45 words
A method as recited in claim 7 wherein said elongated body member comprises a first elongated cylindrical portion and a second elongated reduced diameter cylindrical portion and wherein said location of the spiral member comprises locating said spiral member around said second reduced diameter portion.
Claim 12
Dependent Claim
71 words
A method as recited in claim 7 wherein said transversal member includes a pair of integral leg portions defining a substantially V-shaped portion and an elongate connecting member having opposed ends, each end being integrally joined to one of said leg portions, said connecting member and upper portion of said leg portions defining a triangular space therebetween, said connecting step comprising connecting said body portion one end to said connecting member.
