The depressed center and the surrounding upper cushion surface are configured such that the user's weight is essentially supported by the surrounding upper cushion surface whereas the depressed center is substantially non-body-weight-bearing and provides an upward force that contacts and supports a rectal area of a user when the toroidal cushion is sat upon.

## Background
PRIORITY CLAIM
The present application claims the benefit of U.S. Provisional Patent Application No. 61/473,629, filed Apr. 8, 2011, which application is incorporated herein by reference in its entirety.


BACKGROUND
Hemorrhoids and other pain associated with the rectal and rear area have been an ongoing problem for millennia. Many different systems, devices and procedures have been provided over the years in an attempt to alleviate/reduce the pain and/or reduce the symptoms associated with such conditions. However, even after these many years of trying, there has gone unmet a need for effective devices that are simple, usable by the common person, and effective at alleviating both symptoms and discomfort associated with hemorrhoids and other conditions. The present devices, systems and methods remedy one or more of these long-felt needs.
SUMMARY
As can be seen in the drawings and discussion herein, the present devices, systems, etc., are directed to a seating cushion or pillow configured to fit a human posterior and to help alleviate, i.e., reduce, pain and/or symptoms of hemorrhoids or other posterior-related conditions, as well as related methods of making and using such cushions. The cushions can also help reduce the amount and/or intensity of recurrences or flare-ups. The cushions are also very comfortable.
The cushions comprise a front and a back wherein there is a slight but significant downward slope from the back to the front. The cushions are substantially toroidal and therefore comprise a significant depression such as a divot or hole or in the middle of the cushion. In certain embodiments, the toroid is an oval, and the “doughnut hole” of the toroidal cushion need not be hollow all the way through, although such full-bore-hole configuration is typical where the cushion further comprises a cushion cover substantially, e.g., fully, encompassing the cushion.
The upper cushion surface for the “doughnut” of the cushion must be adequately taut across the opening or depression of the toroid or “doughnut” such that the upper cushion surface contacts and provides support for the rectal area of the user when in use. In particular, the upper cushion surface is adequately taut such that the rectal area of the user contacts the covering and is substantially supported thereby such that hemorrhoids, if present, are supported and not left to “dangle”. This provides significant health advantages to hemorrhoid sufferers.
The back-to-front slope may progress in a relatively continuous manner from the front edge to the rear edge of the cushion or it may comprise only a substantial portion of the cushion from the back edge to the front edge, for example starting from about 50% from the back sloping down to about 20% from the front. The slope is relatively gradual, for example at about a five degree to 15 degree angle relative to horizontal. In certain embodiments, the front edge of the cushion is approximately one to three inches thick while the back edge of the cushion is approximately two to five inches thick.
In the event that the cushion is a full toroid (i.e., completely hollow in the “doughnut hole” area of the torus), and preferably regardless of whether the center of the toroid is hollow, the system further includes a cushion cover substantially, tautly covering the hollow of the cushion toroid from side to side and front to back. The cushion cover can be applied to the cushion and retained on the cushion using any desirable approach, such as buttons, zippers, snaps, VelcroTM (i.e., a hook and loop fastener), etc. The cushion cover can be made from any suitable material, typically a resilient, tough fabric such as cotton, polyester, etc.
Preferably, the upper cushion surface, be it the cushion cover or the cushion itself if no extra cover is provided, has a desired frictional quality (coefficient of friction) such that slipping off the cushion is impeded yet the user can still move freely on the cushion to reposition him/herself as desired.
The interior of the cushion can be made of any suitable stuffing, including, for example, natural fibers such as cotton, wood fibers, flax, seed husks, etc., or non-natural fibers such as polyester or rayon. The cushion is generally sized and shaped to fit a human posterior.
The cushion is also typically configured in an oval shape wherein the front-to-back of the cushion is the relatively narrow portion of the oval while the side-to-side portion of the cushion is the relatively wide portion of the oval. For example, the front-to-back dimension of the cushion can be from about 11 to 24 inches, and more typically around 12, 13 or 14 to 18 inches, while the side-to-side dimension of the cushion can be from about 14 to 28 inches, and more typically around 15.5 to 20 inches.
These and other aspects, features and embodiments are set forth within this application, including the following Detailed Description and attached drawings. In addition, various references are set forth herein, including in the Cross-Reference To Related Applications, that discuss certain systems, apparatus, methods and other information; all such references are incorporated herein by reference in their entirety and for all their teachings and disclosures, regardless of where the references may appear in this application.

DETAILED DESCRIPTION
Turning to the figures, FIGS. 1-3 depict views of one embodiment of a toroidal cushion 2 as discussed herein with and without its top covering 12. The seating cushion system shown comprises a toroidal cushion 2 sized to fit and support a posterior of a human user. The toroidal cushion 2 slopes 6 significantly from the back 28 toward the front 30 of the toroidal cushion 2. The toroidal cushion 2 comprises an upper cushion surface 4 comprising a depressed center 8 within a surrounding upper cushion surface 10. The depressed center 8 and the surrounding upper cushion surface 10 are configured such that the user's weight is essentially supported by the surrounding upper cushion surface 10 whereas the depressed center 8 is substantially non-body-weight-bearing and provides an upward force that contacts and supports a rectal area of a user when the toroidal cushion 2 is sat upon.
The toroidal cushion 2 can comprise an inner toroid 14 and a cushion cover 12 that is a separate piece of fabric. The depressed center 8 of the inner toroid 14 can be hollow as in FIGS. 1-3 or not fully or entirely hollow, as in FIGS. 4-5. The cushion cover 12 spans at least the depressed center 8 to tautly provide a surface across the depressed center 8 that provides the upward force that contacts and supports a rectal area of a user when the toroidal cushion 2 is sat upon. The cushion cover 12 can comprise any suitable attachment or closure device such as zipper 16.
The toroidal cushion 2 in these figures is oval with a long axis 32 of the oval extending side-to-side and a short axis 34 extending back-to-front. The toroidal cushion 2 can be about 12 to 15 inches from front to back, and 15 to 19 inches from side to side. The toroidal cushion 2 can also be from about 3 to 4 inches thick at the back and from about 1.5 to 2 inches thick at the front.
The toroidal cushion 2 can also comprise a plurality of dividers 18 configured to create a plurality of separate zones within the cushion with different heights of filler material 20 to create the slope 6. At least two of the dividers 18 can be located within opposed side portions 22 of the cushions. At least two of the dividers 18 are located within forward sections 26 of the opposed side portions 22 of the cushions and are disposed less than 180° from each other. In some embodiments, the dividers 18 are angled relative to perpendicular within the cushion.
As shown in FIG. 2 the slope 6 begins at about 1 inch from the front of the toroidal cushion 2 and extends back to about 2 inches from the rear of the toroidal cushion 2. As shown in FIG. 4, the slope 6 from front to back can be substantially continuous, or as shown in FIG. 5, the slope 6 from front to back can begin about 2 inches to the rear of the front edge 36 of the toroidal cushion 2 and extend rearwardly to about the midway point 38 of the toroidal cushion 2. The toroidal cushion 2 is filled with a polyester stuffing or a natural filler material 20.
FIG. 6 depicts a top plan view of a pattern 40 for a top portion 48 of an inner toroid 42 for an exemplary cushion 2 herein. FIG. 7 depicts a bottom plan view of a pattern 40 for a bottom portion 50 of the inner toroid 42 of FIG. 6. The pattern includes darts 24, label 44 and dividers 18. In the embodiment shown, two dividers 18 are located in opposed forward sections 26 of side portions 22. Cut out 46 reflects the fact that the top portion 48 is smaller than the bottom portion 50 to provide for the forward slope of the toroidal cushion 2.
FIG. 8 depicts a side plan view of a cushion divider 18 as discussed herein.
FIGS. 9-11 depicts views of a pattern 52 for a cushion cover 12 for an exemplary cushion 2 herein. FIG. 9 depicts the top or bottom piece 56, which can be identical as depicted. FIG. 10 depicts a plan view of a pattern for a front piece 58 of a cushion cover 12 that connects the top and bottom pieces 56 of the cushion cover 12. Slopes 6 correlate to the slope of toroidal cushion 2. FIG. 11 depicts a plan view of a pattern 52 for a rear piece 58 of a cushion cover 12 that connects the top and bottom pieces 56 of the cushion cover 12, including zipper cut outs 54.
The aspects herein also include methods comprising either or both making or using of the toroidal cushion embodiments discussed herein. For example, the cushions can be used to alleviate hemorrhoid symptoms such as hemorrhoid pain. Such methods can comprise identifying a person as having hemorrhoid symptoms and/or pain, then having the person suffering the hemorrhoids sit on the toroidal cushion 2 as desired.
