Abstract

Abstract An improved elastic band is disclosed having dimensions and design specifically adapted for tying off human fallopian tubes or similar internal, tubular members. The band of the present invention has an internal diameter at least about 50% larger than the diameter of similar bands previously employed and ranges from 1.4 to 2.2 mm. The length or thickness of the band is at least 50% greater than the internal diameter of the band; and, in a preferred embodiment, the internal diameter of the band at both ends is about 0.2 to 0.6 mm. smaller than the internal diameter at the mid portion of the band. Thus, in a preferred embodiment, the internal diameter of the tube at its mid portion is 1.8-2.2 mm, at both ends is 1.4 to 1.8 mm, and the length of the band is 2 to 3.5 mm.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 68 words
An elastic band adapted for tying off human fallopian tubes, said band consisting of a small, hollow tube whose inside diameter at its midsection is 1.8 to 2.2 mm and whose length is at least about 50% greater than the minimum inside diameter of said tube, the inside diameter of the tube being 0.2 to 0.6 mm. smaller at both ends that at the midsection of the tube.
Claim 2
Dependent Claim 68 words
An elastic band adapted for tying off human fallopian tubes, said band consisting of a small, hollow tube whose inside diameter at its midsection is 1.8 to 2.2 mm and whose length is at least about 50% greater than the minimum inside diameter of said tube, the inside diameter of the tube being 0.2 to 0.6 mm. smaller at both ends that at the midsection of the tube.
Claim 3
Dependent Claim 16 words
The elastic band of claim 1 which has a outside diameter of 3 to 4 mm.
Claim 4
Dependent Claim 21 words
The elastic band of claim 1 wherein the inside diameter of the tube at both ends is 1.4 to 1.8 mm.
Claim 5
Dependent Claim 17 words
The elastic band of claim 3 wherein the length of the tube is 2.1 to 3.5 mm.
Claim 6
Dependent Claim 82 words
An elastic band for tying off internal tubular members of the human body, said band consisting of a small hollow tube having an outside diameter of 3 to 4 mm., an inside diameter at the midsection of the tube of 1.8 to 2.2 mm. and an inside diameter at both ends thereof which is 0.2 to 0.6 mm. smaller than said midsection inside diameter, and a length which is at least about 50% greater than the minimum inside diameter of said tube.
Claim 7
Dependent Claim 82 words
An elastic band for tying off internal tubular members of the human body, said band consisting of a small hollow tube having an outside diameter of 3 to 4 mm., an inside diameter at the midsection of the tube of 1.8 to 2.2 mm. and an inside diameter at both ends thereof which is 0.2 to 0.6 mm. smaller than said midsection inside diameter, and a length which is at least about 50% greater than the minimum inside diameter of said tube.
Claim 8
Dependent Claim 13 words
The elastic band of claim 5 which is 2.1 to 3.5 mm. long.
