Abstract
Abstract A tampon prepared for use and used so that the narrow end of a tampon, which is wide at one end and narrow at the other end when subjected to intravaginal pressures, is the last point of attachment for the withdrawal string and that narrow end is located deepest in the vagina. After being placed, the string extends from the narrow end, along the side of the tampon, and through the introitus to the outside of the vagina. A pull on the withdrawal string will reverse the tampon during removal so that the narrow end is the first portion of the tampon to exit the vagina.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A catamenial device comprising: A. An inserter having a proximal end adapted to be the leading end during insertion into a vagina; B. A flexible, absorbent tampon having a proximal end and a distal end, said tampon being within said inserter, the proximal end of said tampon being located adjacent the proximal end of said inserter; and C. A flexible withdrawal string, said string being attached to the tampon and depending therefrom at a last point of attachment, said last point of attachMent being at the exterior of the proximal end of the tampon, whereby upon placement of the tampon in a vagina, a pull on the string turns the tampon end for end and permits removal of the tampon with its proximal end leading.
Claim 2
Dependent Claim
125 words
A catamenial device comprising: A. An inserter having a proximal end adapted to be the leading end during insertion into a vagina; B. A flexible, absorbent tampon having a proximal end and a distal end, said tampon being within said inserter, the proximal end of said tampon being located adjacent the proximal end of said inserter; and C. A flexible withdrawal string, said string being attached to the tampon and depending therefrom at a last point of attachment, said last point of attachMent being at the exterior of the proximal end of the tampon, whereby upon placement of the tampon in a vagina, a pull on the string turns the tampon end for end and permits removal of the tampon with its proximal end leading.
Claim 3
Dependent Claim
29 words
The device of claim 1 wherein said tampon is constructed of resilient, elastic material, is generally conically shaped, and wherein said proximal end is the apex of the cone.
Claim 4
Dependent Claim
65 words
The device of claim 1 wherein the tampon is constructed of a resilient, elastic material and has a dry material modulus of compressibility for a 25 percent compression deflection ranging from about 0.2 to 0.6 pounds per square inch and a wet material modulus of compressibility to attain 75 percent of the original dry thickness ranging from about 0.1 to 0.3 pounds per square inch.
Claim 5
Dependent Claim
14 words
The device of claim 3 wherein the tampon has a cellular foam absorbent body.
Claim 6
Dependent Claim
14 words
The device of claim 4 wherein the tampon has a polyurethane mensesphilic absorbent body.
Claim 7
Dependent Claim
26 words
The device of claim 1 wherein the tampon is constructed of a resilient, elastic material and has a hollow cavity propagating inwardly from its distal end.
Claim 8
Dependent Claim
45 words
The device of claim 1 wherein the unattached portion of the string is enclosed in the inserter between the exterior surface of the tampon and the interior surface of the inserter from the last point of attachment to beyond the distal end of the tampon.
Claim 9
Dependent Claim
116 words
The device of claim 1 wherein said tampon has an open celled, polyurethane, resilient, elastic, mensesphilic absorbent body, said body having a generally conical exterior surface, said body having an interior cavity, said cavity similar to and coaxial with the exterior of the tampon, the bases of said tampon and said cavity being coplanar, the apex of the tampon being the proximal end, and the absorbent body having a dry material modulus of compressibility for a 25 percent compression deflection ranging from about 0.2 to 0.6 pounds per square inch and a wet material modulus of compressibility to attain 75 percent of the original dry thickness ranging from about 0.1 to 0.3 pounds per square inch.
