Abstract
Abstract Disclosed is a method for treating carcinoma of the uterine cervix by judiciously applying radioactive material immediately adjacent the uterine cervix for an extended period of time empirically determined by the radiologist. The novel method comprises inserting three radioactively chargeable components including a central tubular tandem vaginally longitudinally into the uterine cervix and two non-lineal tubular ovoidal assemblies longitudinally locatable at the cervix and positioned laterally between the respective vaginal walls and the uterine cervix. The ovoidal assemblies are conveniently removably and pivotably connected to the central tandem component externally of the vagina along the sagittal plane through a novel adapter member whereby the radioactively chargeable ovoidal assemblies tend to remain within a laterally extending plane located substantially midway the transversely separated vasicovaginal and rectovaginal septa, even though the patient periodically shifts her reclining posture during the extended treatment by said vaginally protruding apparatus.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
A method of treating carcinoma comprising the steps of: inserting a tubular tandem and first and second tubular side assemblies through the vaginal orifice with the tandem extending into the uterus and the first and second side assemblies being positioned against the vaginal wall; and emitting radiation from at least one of the tubular tandem and first and second tubular side assemblies; the step of inserting the tubular tandem and first and second tubular side assemblies including the steps of inserting the tubular tandem with a mounting portion and a radiating portion attached to each other, inserting the first tubular side assembly with a first-tubular-side-assembly mounting portion and a first-tubular-side-assembly radiating portion attached together and inserting the second tubular side assembly with a second-tubular-side assembly mounting portion and a second-tubular-side assembly radiating portion attached together and with the mounting portions of each extending through the vaginal orifice in the sagittal plane and the radiating portions being located adjacent to the vaginal walls within a plane substantially perpendicular to the sagittal plane.
Claim 2
Independent Claim
171 words
A method of treating carcinoma comprising the steps of: inserting a tubular tandem and first and second tubular side assemblies through the vaginal orifice with the tandem extending into the uterus and the first and second side assemblies being positioned against the vaginal wall; and emitting radiation from at least one of the tubular tandem and first and second tubular side assemblies; the step of inserting the tubular tandem and first and second tubular side assemblies including the steps of inserting the tubular tandem with a mounting portion and a radiating portion attached to each other, inserting the first tubular side assembly with a first-tubular-side-assembly mounting portion and a first-tubular-side-assembly radiating portion attached together and inserting the second tubular side assembly with a second-tubular-side assembly mounting portion and a second-tubular-side assembly radiating portion attached together and with the mounting portions of each extending through the vaginal orifice in the sagittal plane and the radiating portions being located adjacent to the vaginal walls within a plane substantially perpendicular to the sagittal plane.
Claim 3
Dependent Claim
110 words
A method according to claim 1 in which the step of inserting includes the steps of: first inserting the tandem into the uterus; secondly inserting one of said first and second side assemblies through the vaginal orifice to a location in which the radiating portion is adjacent to the vaginal walls within a plane substantially perpendicular to the sagittal plane and mounting it in position with its mounting portion in the sagittal plane; and thirdly inserting the other of said side assemblies with its radiating portion in the plane perpendicular to the sagittal plane adjacent to the vaginal walls and mounting it with its mounting portion in the sagittal plane.
Claim 4
Dependent Claim
72 words
A method according to claim 2 in which the step of inserting includes the step of: pivotally mounting the first and second side assemblies to said tandem by a pivot axis means lying within the sagittal plane; and pivotally holding said first and second side assemblies by mounting means for preventing rotation of the first and second side assemblies about their respective longitudinal axis while they pivot about said pivotal axis means.
Claim 5
Dependent Claim
48 words
The method according to claim 2 in which the step of radiating includes the step of inserting radioactive material into at least one of said tandem and first and second side assemblies after said tandem and first and second side assemblies have been inserted and mounted in place.
Claim 6
Dependent Claim
72 words
The method according to claim 4 in which the step of inserting includes the step of: pivotally mounting the first and second side assemblies to said tandem by a pivot axis means lying within the sagittal plane; and pivotally holding said first and second side assemblies by mounting means for preventing rotation of the first and second side assemblies about their respective longitudinal axis while they pivot about said pivotal axis means.
Claim 7
Dependent Claim
246 words
A method according to claim 1 in which the step of inserting includes the steps of: measuring the longitudinal uterus length; placing an adapter member around a tubular tandem having a straight portion with a slight curvature at its end; inserting the tandem through the vaginal opening with the curved end being inside the uterus and following the curvature of the uterus and the straight portion extending outside of the vaginal opening with the adapter being positioned outside the vaginal opening; inserting a first of the first and second side assemblies having a mounting portion and a radiation portion, with the radiation portion forming an obtuse angle with the mounting portion; pivotally attaching the mounting portion of the first inserted one of said first and second side assemblies to the mounting portion of the tandem by means of said adapter; inserting the other of said first and second side assemblies having a mounting portion and a radiation portion, with the radiation portion forming an obtuse angle with the mounting portion; mounting the mounting portion of said second inserted side assembly to the mounting portion of said tandem by said adapter; and moving the radiation portions of said first and second side assemblies in opposite directions within a plane perpendicular to the sagittal plane and with said mounting portion and radiation portion lying in the same plane and with the mounting portions of the first and second side assemblies and the tandem lying in the sagittal plane.
Claim 8
Dependent Claim
72 words
A method according to claim 6 in which the step of inserting includes the step of: pivotally mounting the first and second side assemblies to said tandem by a pivot axis means lying within the sagittal plane; and pivotally holding said first and second side assemblies by mounting means for preventing rotation of the first and second side assemblies about their respective longitudinal axis while they pivot about said pivotal axis means.
Claim 9
Dependent Claim
57 words
A method according to claim 1 in which the step of radiating from at least one of said tandem and first and second side assemblies includes the step of inserting into the tubular tandem and the first and second side assemblies a radioactive material after said tandem and first and second side assemblies are mounted into position.
Claim 10
Dependent Claim
72 words
A method according to claim 8 in which the step of inserting includes the step of: pivotally mounting the first and second side assemblies to said tandem by a pivot axis means lying within the sagittal plane; and pivotally holding said first and second side assemblies by mounting means for preventing rotation of the first and second side assemblies about their respective longitudinal axis while they pivot about said pivotal axis means.
Claim 11
Dependent Claim
72 words
A method according to claim 1 in which the step of inserting includes the step of: pivotally mounting the first and second side assemblies to said tandem by a pivot axis means lying within the sagittal plane; and pivotally holding said first and second side assemblies by mounting means for preventing rotation of the first and second side assemblies about their respective longitudinal axis while they pivot about said pivotal axis means.
