Abstract
Abstract A method for determining the extensibility of selected non-excised tissue of the uterine cervix, ear or skin by: (a) positioning the tissue between two force transmitting members, applying a varying compressive force to the tissue through the force transmitting members, measuring the force applied and the displacement of the non-excised tissue resulting from said force, and calculating the modulus of extensibility curve of the tissue, or (b) positioning the tissue between two force transmitting members, applying a constant compressive force to the tissue through the force transmitting members, measuring the displacement of the tissue resulting from the application of the force, and continuously monitoring the changes in the displacement of the tissue over a period of time to determine the changes in the extensibility of the tissue while the constant force is applied.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A method for measuring the modulus curve of extensibility for selected nonexcised tissue of the uterine cervix comprising: (a) positioning the tissue at the lip of the uterine cervix between two members; (b) applying an increasing compressive force to the tissue which increases from a minimum force to a maximum force; (c) measuring the instantaneous force applied and the displacement of tissue resulting from said force over the range of forces applied; (d) calculating the ratio of the instantaneous force applied to the displacement resulting therefrom; (e) deriving the modulus curve of extensibility for the uterine tissue from the calculated ratios; and (f) displaying the modulus curve of extensibility over the range of forces applied.
Claim 2
Independent Claim
115 words
A method for measuring the modulus curve of extensibility for selected nonexcised tissue of the uterine cervix comprising: (a) positioning the tissue at the lip of the uterine cervix between two members; (b) applying an increasing compressive force to the tissue which increases from a minimum force to a maximum force; (c) measuring the instantaneous force applied and the displacement of tissue resulting from said force over the range of forces applied; (d) calculating the ratio of the instantaneous force applied to the displacement resulting therefrom; (e) deriving the modulus curve of extensibility for the uterine tissue from the calculated ratios; and (f) displaying the modulus curve of extensibility over the range of forces applied.
Claim 3
Independent Claim
90 words
A method for determining changes in the extensibility of selected nonexcised tissue of the uterine cervix, ear or skin comprising: (a) positioning the tissue between two force transmitting members; (b) applying a constant compressive force to said tissue through said force transmitting members; (c) measuring the displacement of the tissue resulting from the application of said force; and (d) continuously monitoring the changes in the displacement of said tissue over a period of time to determine the changes in the extensibility of said tissue while said constant force is applied.
Claim 4
Independent Claim
90 words
A method for determining changes in the extensibility of selected nonexcised tissue of the uterine cervix, ear or skin comprising: (a) positioning the tissue between two force transmitting members; (b) applying a constant compressive force to said tissue through said force transmitting members; (c) measuring the displacement of the tissue resulting from the application of said force; and (d) continuously monitoring the changes in the displacement of said tissue over a period of time to determine the changes in the extensibility of said tissue while said constant force is applied.
