Abstract

A prosthesis comprising a pancake-shaped body (100), a neck (110) and a flared flattened handle (120) sized and shaped to shield the posterior vaginal wall (610) from frictional contact during coitus. This self-retaining prosthesis comprises a means to retain the pancake-shaped body (100) within the vagina and a means to prevent the flared flattened handle (120) from entering the vagina during insertion of the prosthesis or during coitus. This prosthesis decreases the volume of the vagina and decreases the area of the vaginal opening providing a non-surgical, cost-effective solution to tightening a woman's vagina. The posterior vaginal wall prosthesis enables women who have larger vaginas to use tampons.

Description

PROSTHESIS OF FEMALE BACK WALL The present application relates generally to medical devices, particularly to a prosthesis constructed to duplicate the posterior vaginal wall.

After an episiotomy, vaginoplasty or vaginal tear, the remaining healed scar on the posterior vaginal wall may be painful or the area on the posterior vaginal wall may be hypersensitive. There is a need for a device for covering sensitive area, which can be used in the posterior vaginal wall during intercourse, to reduce friction in this area to help with hypersensitivity in this area. The standard medical practice when performing an episiotomy is to cut from the entrance (introitus) to and within the peritoneum. These areas are the site of varisurgical and non-surgical traumas that include tears, occlusions, sutures, scars, yagas or ulcers, genital warts and genital herpes, all of which can cause the posterior vaginal wall, the entrance and the area to be hypersensitive. of perineum.

In addition, a woman's vagina and the entrance of the vagina naturally differ in size from person to person. Factors such as age, over stretched or excessive stretching by childbirth or sexual activities, can additionally cause the vagina and the entrance of the vagina lose elasticity. To help tighten or tighten your vagina, a woman has few options available to choose from. These options have varying degrees of success and risk.

From the earliest times, some women have used creams that claim to narrow the vagina. The evidence shows that remarkable narrow effects of these ointments are considered ineffective. Application of the cream to the inner walls of the vagina is difficult, embarrassing and should be properly synchronized to correspond with the sexual relationship. Some of the creams They contain benzocaine, alum or petrolatum, none of which is recommended for insertion into the vagina.

Another alternative is to make an alum shower. Alum showers are not recommended by doctors, they can be irritating and are associated with increased risk of pelvic and vaginal infection. Alum is an astringent that acts to contract the walls of the vagina, but there is no way to judge how long the constriction will last or a way to control the extent of narrowing.

Performing exercises designed to strengthen the pubococcygeal muscles, such as the exercises developed by Dr. Amold Kegel of the University of California, which is a doctor-recommended way to exercise the vaginal muscles to tighten the vagina. For those who find it difficult to identify these muscles, bioinformation or biofeedback systems may be useful. These muscles can also be exercised using varivaginal exercise devices (U.S. Patent Number 4,241, 912 issued to Mercer et al. (1980), U.S. Patent Number 4,048,985 issued to Sasse (1977), U.S. Patent Number 4,895,363 issued to Plevnik et al (1990), U.S. Patent Number 5,256,123 issued to Reinbolt (1993), to name a few). A disadvantage of these methods of exercise is that it takes a long time, an average of 6 to 12 weeks, for results to be seen, so one must dedicate to maintain the muscle development program for a sufficiently long time to be of benefit. Also, like any muscle, if the muscles are not continuy worked, the pubococcygeal muscles will lose their strength. Another disadvantage is that to be of benefit during a sexual relationship, the woman must consciy flex her inner muscles, thus removing her ability to relax and enjoy the act of sexual intercourse itself.

The electrotherapy of the vagina as described in the U.S. Patent. Number 3,640,284 granted to De Langis (1972), reproduces the physical and chemical phenomena connected with normal muscular work. A small electronic probe is placed in the vagina and painless electrical currents, low frequency cause contractions of the vaginal muscles. Alternatively, the vaginal muscles can be exercised with attractor magnets as described in US Pat. Number 6,672,996 issued to Ross et al. (2004). Unfortunately, both of these methods are expensive and are not viable for use in domestic conditions.

Vaginoplasty is a surgical procedure that helps tighten or tighten the vaginal muscles, as well as supporting tissues of the vaginal wall. Any excess vaginal mucosal tissue is cut or removed with a laser. The result is an immediate decrease in the size of the vaginal muscles. This is a costly procedure, and has the following risks: problems with anesthesia, bleeding, bruising, infection with inflammation, soreness and sensitivity and post operative healing. There is also the risk of losing sensitivity due to complications within the area of the vaginal wall and muscles.

Canadian Patent Application Number 2,673,567, by Mark, filed on June 26, 2008, describes a sexual assist device that is inserted into a human vagina, to provide an increased sense of fullness or satiety for the female and a sense of narrowness increased and friction for a man's penis during intercourse.

Deficiencies in Mark's device and method of sexual assistance They are as follows: (a) Mark's device is not designed to protect the posterior vaginal wall, entrance or perineum while in use (use here includes sitting, walking, normal daily activities and intercourse). Mark's device neglects to cover a wide area that includes the posterior vaginal wall, the entrance and the perineum, thus exposing women, who experience hypersensitivity, to frictional contact in these areas. The posterior vaginal wall, the entrance and the perineum, are often the location or site of hypersensitivity, including but not limited to, tears, occlusions, sutures, scars, sores, warts and herpes. In addition, the Mark device guarantees frictional contact over the entire extension of the posterior vaginal wall, the entrance and the perineum, when the device is connected to a penis by means of a ring or a condom. This frictional contact further irritates hypersensitive areas. (b) Mark's device is not designed to be used apart from intercourse. Your device is not designed to be held exclusively by the vagina at all times. Inside the vagina, Mark's device is designed with only a retention mechanism, a bulbous head. When a woman uses Mark's device and is upright, the device is susceptible to gravity movement such that the bulbous head falls toward the vaginal entrance. Mark's modality has an anal penetrator that serves as a second means of retention, however this form of retention complicates daily activities in the toilet and otherwise may not be suitable for use throughout the day. Mark's device is not designed to be used comfortably all day and all night. (c) the Mark device has no shape geometry that allows the device to support itself when inserted into the vagina and remains supported during use without penetrating the anus. When Mark's device is located in a single hole, his device is not self-locating, it is not self-retaining, it does not remain in a position defined by the user and it does not resist or impede rotation. Mark's device does not have a mechanism to deploy, which serves to place the device in the vagina when it passes the muscles of the vaginal entrance nor its device has shape and geometry to prevent the device from entering completely into the vagina while inserting and while it is in use. Mark's device does not have features that hold the device in a predetermined position defined by the user, inside and outside the vagina. (d) Mark's device is not designed to be exclusively by the vagina to allow a woman to use a blood collection device, such as a tampon. In addition, your device does not work to support a method for transdermal drug delivery. (e) Mark's device is not designed to house insertable and detachable electronic devices. Your device has inter-built electronic devices that increase manufacturing costs, limit end user options and make your device less easily recyclable. (f) Mark modalities that are manufactured from a simple material stretch the muscles of the entrance when the device is inserted. To reduce the minimum stretch of the entrance muscles, Mark has a modality that is cylindrically foldable for insertion into the vagina, however, this modality requires at least two different types of materials and a more complex manufacturing process that complicates recycling Of the device. Mark's device does not take advantage of an engineering form that is simple to manufacture and that can Hand rolled in a narrow cylinder for easy insertion into the vagina without stretching the muscles of the entrance.

Therefore, there is a need for some women for a cost-effective, non-surgical solution, to protect at all times a sensitive area in the posterior vaginal wall, the entrance and the perineum area, to restore the sensation of a narrow vaginal entrance. and allow women with larger vaginas to use a tampon. In this aspect, the posterior vaginal wall prosthesis substantially meets this need. The posterior vaginal wall prosthesis according to the present invention is substantially separated from the conventional concepts and designs of any prior art.

OBJECTS AND ADVANTAGES Accordingly, several objects and advantages of the posterior vaginal wall prosthesis are: (a) provide a prosthesis that is self-retaining, hands-free and ergonomic and that protects against frictional contact in the posterior vaginal wall, the entrance and the perineum area; (b) it provides a prosthesis that effectively decreases the volume of the vagina and decreases the area of the vaginal opening, thereby providing a cost-effective, non-surgical solution to give a woman the sensation of a narrow vagina; (c) provide a prosthesis that will allow couples to achieve the desired adjustment and the desired sensations during a sexual relationship, decreasing the need to look outside the relationship for the desired adjustment and sensations, thus decreasing the transmission of AIDS (AIDS) and other diseases or sexually transmitted infections; (d) provide a prosthesis that increases sensations for the male partner by applying more pressure around the penis; (e) providing a prosthesis that prevents tampons from detaching from larger vaginas, thus allowing the use of tampons; (f) providing a prosthesis that has design features to ensure that the prosthesis remains in place while the vagina is penetrated by foreign objects; (g) providing a prosthesis that is rolled into a cylindrical tube-like shape that allows easy insertion into the vagina, the muscles of the vaginal inlet do not require expansion to allow insertion of the prosthesis; (h) providing a prosthesis that unfolds naturally after insertion to provide the necessary tension in its deployed state to self-retain, self-locate and remain in place in the vagina; (i) provide a prosthesis that has a widened flattened handle that resides on the outside of the vaginal entrance, which follows the natural contours of the perineal area that protect this area; (j) providing a prosthesis having a widened flattened handle that serves to prevent the entire device from entering the vagina; (k) providing a prosthesis that is simultaneously retained both inside and outside the vagina; (I) provide a prosthesis that resists rotation after being inserted into the vagina.

Additional objectives and advantages will be apparent from a consideration of the following description and drawings.

DETAILED DESCRIPTION - FIGURES 1 -6 - FIRST MODALITY One embodiment of the posterior vaginal wall prosthesis that resembles a vane with a curved handle is illustrated in Figures 1-5. This embodiment comprises a cake-shaped body 100, a narrow neck 1 10, an enlarged squashed handle 120, and a medium-section bulb 130. The cake-shaped body 100 includes two projecting lateral wings 140, 140. The narrow neck 110 connects to the body in the form of cake 100, with the flattened broadened handle 120 as illustrated in Figure 1. This embodiment comprises a unitary, flexible, elastic structure, wherein the cake-shaped body 100 and the enlarged flattened handle 120 are placed in a divergent relationship with an intermediate included angle. Within this included angle, the teardrop-shaped mid-section bulb 130 is located at the base of the pie-shaped body 100 near the narrow neck 110 with the largest part of the bulb positioned closest to the narrow neck 110 as illustrated in Figure 2. The posterior vaginal wall prosthesis is dimensioned and configured to be placed in a human vagina as shown in Figure 6 in such a way that the end of the pie-shaped body 100 is placed towards the posterior fornix 620 of the vagina, the medial section bulb 130 is located to make contact with the posterior vaginal wall 610, the narrow neck 1 10 is at the entrance 640 and the enlarged squashed handle 120 directs towards the perineum 630. It is important to note that the narrow neck 110 It has a half moon shape to allow sexual intercourse when the prosthesis is placed in a vagina. The cross section of the narrow neck 110 is illustrated in Figure 5.

The preferred material for the manufacture of this embodiment is a medical grade silicone or an elastomeric gel with a durometer measurement between 15-25 on the Shore O hardness scale. Preferred elastomeric gels for use are described in US Pat. No. 5, 807,360 awarded to Shubin (1998). This modality of the posterior vaginal wall prosthesis can be elaborated with any other material that comprises the following characteristics. The material should be soft and flexible and deformable by human fingers. The material should have an elastic memory to avoid permanent deformation and allow the prosthesis to unroll naturally after insertion into the vagina. The material should also be stable and capable of multiple washes without deterioration. The material should also have density and tactile sensation of human skin and be able to easily transmit vibrations and heat through the material.

The posterior vaginal wall prosthesis is molded using conventional liquid injection molding techniques and technologies.

OPERATION - FIGURES 1-6 - FIRST MODALITY Beginning on one of the projecting lateral wings 140 and ending with the opposite projecting lateral wing 140, the cake-shaped body 100 is wound with the medium-section bulb 130 on the outside. The rolled-up cake-shaped body 100 is then inserted into the vagina until the narrow neck 110 is located in the inlet 640 and the enlarged squashed handle 120 resides on the outside of the vagina, adjacent to the perineum 630 (see placement in the passage). vaginal vagina in Figure 6). Once inside the vaginal cavity, due to the natural tendency of the prosthesis material to return to its original shape, the prosthesis will unroll. However, a full deployment is not necessary to work as the prosthesis is intended. Slight minor displacements for comfort can be made by adjusting the widened flattened handle 120. In this position, the prosthesis reduces the volume of the internal cavity and reduces the area of the vaginal entrance. In addition, various geometric configurations of narrow neck can emulate a larger male sexual organ. The mid-section bulb 130, and the shape of the cake-shaped body 100 act as a means of retention, to retain the prosthesis inside the vagina. The shape of the enlarged squashed handle 120 acts as prevention means to prevent the enlarged squashed handle 120 from entering the vagina.

To remove the prosthesis, the enlarged squashed handle 120 is clamped and the prosthesis is gently removed from the vagina. Due to the shape and deformability of the pie-shaped body 100, the prosthesis will naturally fold the wings 140 to allow the prosthesis to be removed. The prosthesis can then be subjected to cleaning and reuse.

To use the posterior vaginal wall prosthesis with a tampon, the prosthesis is placed in position as described above and the tampon is then inserted in place following the instructions for insertion of the tampon. The buffer is then removed and changed as required. The prosthesis is You can remove, wash and re-insert as required.

DESCRIPTION - FIGURES 7-11 - SECOND MODALITY Another embodiment of the posterior vaginal wall prosthesis is shown in Figures 7-1 1. The embodiment shown in Figures 7-11 comprises the texture 280 on the non-bulbous side, a deformable body retainer 240, embedded in the body in cake form 100, a deformable handle retainer 250 embedded in the flattened collapsed section 120, finger holes 260 and 270, and a recess 290 in the mid-section bulb 130. The texture 280 is provided in the cake-shaped body 100 on the non-bulbous side and serves to act as an additional means of retention by creating a superior friction surface. This surface texture 280 serves to improve the stimulation of the male sex organ and effectively duplicate the texture of the posterior vaginal wall 610. It should be noted that the localized texture 280 or the texture 280 on the entire surface of the prosthesis aids in maintaining tampons. The deformable body retainer 240 applies continuous pressure in an attempt to crush the body in the form of a pie 100 in the vagina after insertion. The shape of the pie-shaped body 100, the mid-section bulb 130, the body retainer 240, and the texture 280 serve to support the posterior vaginal wall prosthesis within the vagina. The shape of the flattened broadened handle 120 and the handle retainer 250 reduce the tendency for the prosthesis to enter the vagina during intercourse. If and / or when lubricants are used, the prosthesis can become slippery; the finger hole of the body 260 and the finger hole of the handle 270 serve as means to more easily locate and hold the prosthesis.

The recess 290 can house a vibration and / or pulsating device commonly known as a "bullet" vibrator (not shown). This comprises a electrically displaceable motor with an eccentric mounted load, encapsulated in a generally cylindrical cover with a rounded tip. This "bullet" can be remotely energized and controlled and may or may not have electrical wiring, or it may be internally energized by batteries. Some versions only vibrate; others have a range of selectable pulsating modes. With the correct selection of materials, the vibrations and / or pulses will be transmitted through the prosthesis. Alternatively, the recess 290 can house an electrically energized warning device, applying in the same way as the pulsating / vibrating mechanism.

The preferred material for the posterior vaginal wall prosthesis embodiment illustrated in Figures 7-1 1 is the same as the preferred material for the first embodiment, with a different material required for the body retainer 240 and the handle retainer 250 .

The body retainer 240 and the handle retainer 250 are preferably constructed of a similar material used for the first embodiment, although more rigid. The preferred material for the manufacture of the retainers is a medical grade silicone, with a durometer measurement between 25-75 on the Shore A hardness scale. The retainers can also be made of any material with elastomeric properties that can be manually stressed to deform in an easy way The material should be flexible so that the human fingers can roll the prosthesis in a tube-like shape before insertion into the vagina and still be elastic enough to flex back, or close to its original shape. Other common shape memory materials that can be used for retainers include: plastics, rubbers, nylons and polyurethanes. Round retainers 240 and 250 are illustrated in the embodiment of Figures 7-1 1, however, a rectangular, triangular or any other shape may be molded on top of the prosthesis to facilitate the same bending function.

The retainers themselves can be manufactured using standard liquid injection molding technologies and techniques. However, the retainers can also be standard silicone O-ring retainers, standard, inventory, easy to process, as illustrated in the embodiment of Figures 7-1 1.

The prosthesis with retainers of FIGURES 7-1 1 is manufactured using conventional liquid injection molding techniques and technologies.

OPERATION - FIGURES 7-1 1 - SECOND MODALITY To operate the embodiment of FIGS. 7-1 1, if desired, the user first inserts a "bullet" or heating device into the recess 290 of the prosthesis, securing the "bullet" or heating device in the recess 290 with a snap fit. Then, the embodiment of FIGURES 7-1 1 is operated in the same manner as the first embodiment of FIGURES 1-6. In addition, the user may use the loop finger hole 250 of the vaginal posterior wall prosthesis modality of FIGS. 7-1 1 to remove the prosthesis from the vagina. The body retainer 240 will deform due to its elastic nature to allow separation. A thread can also be attached to the finger hole of the handle 270, to assist in removing the prosthesis.

If the prosthesis slides completely into the vagina, the finger hole of the handle 270 and the finger hole of the body 260 serve as a means to locate, hold and remove the prosthesis. This is especially useful if additional lubricants are used.

DETAILED DESCRIPTION - FIGURES 2-16 - THIRD MODALITY The embodiment of FIGS. 12-16 illustrates one embodiment of the prosthesis with a combined retainer 310. The combined retainer 310 is a unitary retainer that combines the body retainer 240 and the handle retainer 250 and passes through the narrow neck 1 10. The combined retainer serves the same purpose as separate retainers, which serve to unwind the prosthesis after it is rolled up and inserted into the vagina. The combined retainer 310 also holds the pie-shaped body 100 in place, within the vagina and prevents the flared, squashed end 120 from entering the vagina before, during or after intercourse.

The preferred material for the manufacture of this embodiment is the same material as the material described for the first embodiment shown in FIGS. 1-5. The combined retainer 310 is made from a similar and stiffer material to facilitate the added bending function. The preferred material for the manufacture of the combined retainer 310 is the material of the retainer body 240 described for the embodiment of FIGS. 7-1 1.

The combined retainer 310 is manufactured using conventional liquid injection molding techniques and technologies. The prosthesis with the combined retainer is manufactured using conventional liquid injection molding techniques and techniques.

OPERATION - FIGURES 12-16 - THIRD MODALITY The embodiment of FIGS. 12-16 is operated in the same manner as the embodiment illustrated in FIGS. 1-5 described above.

CONCLUSION, BRANCHES AND REACH Accordingly, the reader will see that the posterior vaginal wall prosthesis can be used to protect the posterior vaginal wall, the entrance and the perineal area. In addition, the prosthesis provides women with new, highly effective, inexpensive, non-surgical means to reduce the volume of the vagina and decrease the area of vaginal entry. The prosthesis is simple to use, easily adjusted for comfort and provides pleasure for both women and men.

While the above figures and descriptions contain many specificities, the reader should not consider these as limitations to the scope of the invention, but simply as exemplifications of several preferred embodiments thereof.
