Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
150 words
A spring member for use as an electrode in an apparatus for cauterization of the uterus of flexible material that will conduct electricity and is collapsible along a longitudinal axis to a size adapted to be passed through the cervical canal for insertion into the uterus, and is expandable in the uterus in a direction transverse to said longitudinal axis whereby it is self-orienting in the uterus, an electric insulating coating except on selected portions of said spring member said selected porTions corresponding to the area of the uterus to be cauterized and being automatically aligned with said area by means of the self-orientation of the spring member upon expansion of the spring member in the uterus and an insulated electric conductor attached to said member for feeding an electric current through said member, said conductor being adapted to extend outside the uterus when the member is in place therein.
Claim 2
Dependent Claim
150 words
A spring member for use as an electrode in an apparatus for cauterization of the uterus of flexible material that will conduct electricity and is collapsible along a longitudinal axis to a size adapted to be passed through the cervical canal for insertion into the uterus, and is expandable in the uterus in a direction transverse to said longitudinal axis whereby it is self-orienting in the uterus, an electric insulating coating except on selected portions of said spring member said selected porTions corresponding to the area of the uterus to be cauterized and being automatically aligned with said area by means of the self-orientation of the spring member upon expansion of the spring member in the uterus and an insulated electric conductor attached to said member for feeding an electric current through said member, said conductor being adapted to extend outside the uterus when the member is in place therein.
Claim 3
Dependent Claim
118 words
The device of claim 1 wherein the spring member comprises a flattened spiral spring member of resilient material having a plurality of windings which are capable of expanding and contracting, said windings tracing a three-dimensional volume of a generally rectangular shape which contains a central axis of expansion and contraction, said windings being expandable and contractable along axes which are generally parallel to said central axis, the distance between opposite windings measured perpendicularly to said central axis and the distance between the ends of said windings when contracted being such that said spring member when so contracted may be passed through the cervical canal of the user of the device for emplacement and subsequent expansion within the uterus.
