Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
193 words
In postoperative treatment following the operational procedure of enlargement of the anal canal, the insertion in said anal canal at intervals of short duration of diminishing frequency of a rectal cone having an insertable portion terminating in a shoulder portion, said insertable portion being about 2 3/4 inches to 4 inches in length and presenting a smooth peripheral surface the transverse cross sections of which along its length are substantially circular and the longitudinal cross section of which in the plane of the longitudinal axis presents a curved blunt end flaring outwardly and toward said shoulder with progressively diminishing gradual curvature to a maximum diameter of about 1 1/4 inches to 1 3/4 inches that is spaced from said shoulder by about 1/4 inch to 1 1/4 inches and a gradually curved waist in the region between said maximum diameter and said shoulder the innermost diameter of which is less than said maximum diameter by about one-eighth inch to five-sixteenths inch, the diameter of said shoulder portion of said cone being sufficiently greater than said maximum diameter of said insertable portion to effectively restrain further insertion when said insertable portion is fully inserted.
Claim 2
Dependent Claim
193 words
In postoperative treatment following the operational procedure of enlargement of the anal canal, the insertion in said anal canal at intervals of short duration of diminishing frequency of a rectal cone having an insertable portion terminating in a shoulder portion, said insertable portion being about 2 3/4 inches to 4 inches in length and presenting a smooth peripheral surface the transverse cross sections of which along its length are substantially circular and the longitudinal cross section of which in the plane of the longitudinal axis presents a curved blunt end flaring outwardly and toward said shoulder with progressively diminishing gradual curvature to a maximum diameter of about 1 1/4 inches to 1 3/4 inches that is spaced from said shoulder by about 1/4 inch to 1 1/4 inches and a gradually curved waist in the region between said maximum diameter and said shoulder the innermost diameter of which is less than said maximum diameter by about one-eighth inch to five-sixteenths inch, the diameter of said shoulder portion of said cone being sufficiently greater than said maximum diameter of said insertable portion to effectively restrain further insertion when said insertable portion is fully inserted.
Claim 3
Dependent Claim
106 words
Postoperative treatment according to claim 1 which comprises the insertion of the rectal cone defined in said claim wherein the insertable portion is substantially 3 3/8 inches in length, the maximum diameter is substantially 1 1/2 inches, the spacing of the maximum diameter from the shoulder is from about seven-eighths inch to about 1 1/4 inches, the minimum diameter of the waist is about one-eighth inch less than said maximum diameter and which comprises a zone about 1 1/2 inches in length extending from said minimum diameter of said waist the diameter of which differs from said maximum diameter by not more than substantially one-eighth inch.
Claim 4
Dependent Claim
173 words
A rectal cone for postoperative insertion in the anal canal comprising an insertable portion terminating in an annular shoulder portion, said insertable portion being about 2 3/4 inches to 4 inches in length and presenting a smooth peripheral surface the transverse cross sections of which along its length are substantially circular and the longitudinal cross section of which in the plane of the longitudinal axis presents a curved blunt end flaring outwardly and toward said shoulder with progressively diminishing gradual curvature to a maximum diameter of about 1 1/4 inches to 1 3/4 inches that is spaced from said shoulder by about three-fourths inch to 1 1/4 inches and a gradually curved waist in the region between said maximum diameter and said shoulder the innermost diameter of which is less than said maximum diameter by about one-eighth inch to five-sixteenths inch, the diameter of said shoulder portion of said cone being sufficiently greater than said maximum diameter of said insertable portion to effectively restrain further insertion when said insertable portion is fully inserted.
Claim 5
Dependent Claim
173 words
A rectal cone for postoperative insertion in the anal canal comprising an insertable portion terminating in an annular shoulder portion, said insertable portion being about 2 3/4 inches to 4 inches in length and presenting a smooth peripheral surface the transverse cross sections of which along its length are substantially circular and the longitudinal cross section of which in the plane of the longitudinal axis presents a curved blunt end flaring outwardly and toward said shoulder with progressively diminishing gradual curvature to a maximum diameter of about 1 1/4 inches to 1 3/4 inches that is spaced from said shoulder by about three-fourths inch to 1 1/4 inches and a gradually curved waist in the region between said maximum diameter and said shoulder the innermost diameter of which is less than said maximum diameter by about one-eighth inch to five-sixteenths inch, the diameter of said shoulder portion of said cone being sufficiently greater than said maximum diameter of said insertable portion to effectively restrain further insertion when said insertable portion is fully inserted.
Claim 6
Dependent Claim
67 words
A rectal cone according to claim 3 wherein said longitudinal cross section of said peripheral surface of said insertable portion comprises a zone from approximately 1 1/4 inches to 1 3/4 inches in length which extends from said minimum diameter of said waist so as to include said maximum diameter and the minimum diameter which differs from said maximum diameter by not more than about three-eighths inch.
Claim 7
Dependent Claim
38 words
A reCtal cone according to claim 3 which includes an integral handle that protrudes from the shoulder end of said cone and is adapted to be grasped with the fingers to facilitate insertion and removal of said cone.
