Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
104 words
A pessary ring structure comprising first and second limbs adapted to fit together to constitute a closed flexible pessary ring, the first limb comprising a flexible arm, a metal electrode at or near each end of the arm and an insulated conductor lead connected to each elecTrode, the leads extending from the arm for the remote application of stimulating potentials, and the second limb comprising a flexible tube which may be cut to a desired length to make the complete ring fit a particular patient, there being provided coupling means for coupling the ends of the tube to the respective ends of the arm.
Claim 2
Dependent Claim
104 words
A pessary ring structure comprising first and second limbs adapted to fit together to constitute a closed flexible pessary ring, the first limb comprising a flexible arm, a metal electrode at or near each end of the arm and an insulated conductor lead connected to each elecTrode, the leads extending from the arm for the remote application of stimulating potentials, and the second limb comprising a flexible tube which may be cut to a desired length to make the complete ring fit a particular patient, there being provided coupling means for coupling the ends of the tube to the respective ends of the arm.
Claim 3
Dependent Claim
40 words
A pessary ring structure as claimed in claim 1 wherein the coupling means comprises a plug for each end of the tube, the plugs fitting the ends of the tube tightly and being attached to the ends of the arm.
Claim 4
Dependent Claim
30 words
A pessary ring structure as claimed in claim 2 wherein the arm is tubular, at least at its ends and the plugs are inserted in place in the tubular ends.
Claim 5
Dependent Claim
30 words
A pessary ring structure as claimed in claim 3 wherein the arm is tubular and is filled with a flexible sealing material which assists in holding the plugs in place.
Claim 6
Dependent Claim
37 words
A pessary ring structure as claimed in claim 1 wherein the coupling means are the electrodes, which are fitted to the ends of the arm which have protruding plug portions for accepting the ends of the tube.
Claim 7
Dependent Claim
26 words
A pessary ring structure as claimed in claim 5 wherein each electrode has a barrel-shaped cylindrical portion which overlaps the ends of the tube and arm.
