     BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    The invention relates to an enhancement device as well as a method of making and using the same. The device can be configured to enhance a sexual experience for the female and can, in particular, be use to provide deep clitoral stimulation. In embodiments, the device may be placed on a penis and/or on a device simulating or being capable of functioning like a penis, e.g., an erect penis.

         [0006]    Conventional devices, however, have not been aimed at or specifically configured to mainly enhance a sexual experience for the female. Nor have such devices had as their main aim to provide deep clitoral stimulation. Such devices also lack the advantageous combination of the material and physical configuration utilized in the invention. In particular, many of the conventional devices are designed to fit and be used only at the base of the penis, even though they are configured to help stimulate the female. When such shorter length devices are utilized, only the outer portion of the vagina is targeted for stimulation. Such devices do no take advantage or take into account the recently discovered information regarding deep branches of the clitoris. In contrast, the invention aims to enhance an entire or substantially an entire length of the penis allowing for deep clitoral stimulation as well as for outer stimulation. Another disadvantage or difficulty associated with conventional devices relates to the material of the devices. Many of these devices are made out of a relatively hard material. This may present less of a problem for short length devices, but becomes more of a concern if such sleeves are lengthen. This is because it is more difficult to install or slide-on a longer sleeve onto the penis. It is believed that this is a major reason why many conventional sleeves are relatively short so as to end up being located at the base of the penis. In contrast, the sleeve of the invention can be made longer, i.e., enhance substantially an entire length of the penis, and be made of a material that can be slid-on more easily, i.e., by being made of a material that allows for it to fold onto itself. 
         [0007]    Masters and Johnson were the first to determine that the clitoral structures surround and extend along the vagina, determining that all orgasms are of clitoral origin. More recently, Australian urologist Dr. Helen O&#39;Connell using MRI technology noted a direct relationship between the legs or roots of the clitoris and the erectile tissue of the clitoral bulbs and corpora, and the distal urethra and vagina. She asserts that this interconnected relationship is the physiological explanation for the conjectured G-spot and experience of vaginal orgasm taking into account the stimulation of the internal parts of the clitoris during vaginal penetration. The invention aims to take advantage of this new information, further details of which can be found in the following publications: O&#39;Connell, Helen,  Anatomy of the Clitoris , J Urol. 2005 October; 174(4 Pt 1):1189-95, PMID 16145367, Federation of Feminist Women&#39;s Health Centers (1991).

     DETAILED DESCRIPTION OF THE INVENTION 
       [0058]    The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing, without wishing to be bound by theory, what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description is taken with the drawings making apparent to those skilled in the art how the forms of the present invention may be embodied in practice. 
         [0059]    The following is a description of non-limiting embodiments of a device, system and/or method for enhancing the sexual experience of a female by stimulating a specific area of the vagina. In particular, the device is configured to provide deep clitoral stimulation. The device is installable on a penis or on a member simulating a penis which is then inserted into the vagina. Repeated movement of an enlarged section of the device located not only in an area of the base of the penis but also mostly on the entire length of the penis shaft, and the resulting stimulating contact between the same and the vagina, can result (all things being equal) in female reaching orgasm in a shorter time than without using the device and/or can result in more intense orgasms and specifically provides for deep clitoral stimulation. The properties of the material of the device are such as to make the installation on the penis, the use on the penis, and/or the stimulation to the vagina easier, more comfortable, and/or ergonomic than known devices. 
         [0060]      FIGS. 1-7  show one non-limiting embodiment of the invention. The device  10  is essentially comprised of a member  1 . The member  1  has first end  2  which is sized and configured to be disposed adjacent a head portion of a penis and a second end  3  which is sized and configured to be disposed adjacent a base portion of a penis. In embodiments, the first end  2  is disposed adjacent a head portion of a penis, but spaced therefrom by a space ranging from about ⅛ inch to about 1 inch, and preferably between about ¼ inch and ½ inch, and the second end  3  is disposed adjacent a base portion of a penis, but spaced therefrom by a space ranging from about ⅛ inch to about 1 inch, and preferably between about ¼ inch and ½ inch. In embodiments, the first end  2  is generally annular and is slightly rounded where it meets the inner surface  4  and where it meets outer surface  5 . In embodiments, the second end  3  is generally annular and need not be rounded where in meets the inner surface  4  and where it meets outer surface  6 . 
         [0061]    In embodiments, the member  1  is a one-piece or integrally formed member. In embodiments, the member  1  can be formed from any suitable material, e.g., a synthetic resin (e.g., plastic or synthetic rubber). In embodiments, the material can be a medical grade and/or a flexible and/or semi-rigid synthetic resin material. In embodiments, the member  1  is made of a transparent or translucent material. In embodiments, the member  1  is made of a material from the family of thermoplastic elastomers. In embodiments, the member  1  is made of a silicone material or silicone/rubber mixtures. One non-limiting advantageous material for the member  1  is Dermasol DS-303 made by or obtainable from the company California Medical Innovations of Pomona, Calif. In embodiments, the member  1  is non-porous and/or does not absorb fluid and/or is made of a solid material. In embodiments, the member  1  is made of an elastically expandable material and/or capable of being of assuming at least one folded configuration as will be described below. In embodiments, the member  1  has the configuration shown in the drawings when made, has an amount of rigidity which allows it to assume the configuration shown in the drawings when a cylindrical shaft is inserted within the member  1  and having an outside diameter which matches that of the inside diameter of the main axial opening, but does not maintain that same shape when the shaft is removed and the member  1  is placed on its side (as shown in  FIG. 1 ), i.e., the member  1  will experience some deflection due to the force of gravity and its own weight. 
         [0062]    The member  1  also has a generally or substantially cylindrical inner surface  4  which defines a main axial through opening and extends along substantially the entire length of the member  1 . This inner surface  4  is sized and configured to be disposed over a shaft portion of a penis and to exert a compressive force thereon so as to create at least a snug fit. This also prevents, reduces or minimizes axial or rotational movement of the member  1  relative to the penis. 
         [0063]    The member  1  further also has plural generally or substantially cylindrical outer surfaces  5 ,  6  and  8  which define distinct and separate sections of the member  1 . Section  5  is sized and configured to be disposed adjacent a head portion of a penis, has a uniform but thinner wall thickness, and a predetermined axial length. In embodiments, a wall thickness of section  5  is between about 0.05 inch and about 0.15 inch, and can preferably be about ⅛ inch. Section  6  is sized and configured to be disposed adjacent a base portion of a penis, has a uniform but thicker wall thickness, and a predetermined axial length. In embodiments, the axial length of section  6  is greater than that of section  5 . In embodiments, a wall thickness of section  6  is between about 0.2 inch and about 0.3 inch, and can preferably be about ¼ inch. Section  8  is sized and configured to be disposed intermediate the base and head portions of a penis, has a uniform but intermediate wall thickness, and a predetermined axial length. In embodiments, the axial length of section  8  is less than that of section  6 . In embodiments, a wall thickness of section  8  is between about 0.15 inch and about 0.25 inch, and can preferably be about 3/16 inch. 
         [0064]    The member  1  further also has plural generally or substantially tapered or chamfered outer surfaces  7  which define distinct and separate short transition sections of the member  1 . Each section  7  is sized and configured to provide a short but smooth and comfortable transition between sections  5  and  8  as well as between sections  8  and  6 . In embodiments, an axial length of each section  7  is between about 0.05 inch and about 0.15 inch, and can preferably be about ⅛ inch. 
         [0065]    As shown in  FIGS. 3 and 4 , the member  1  can be capable of radial expansion (indicated by arrows) in embodiments. In embodiments, the member  1  is capable of assuming an original state after the force(s) causing radial expansion are removed, i.e., the member  1  has memory which allows it to expand elastically and thereafter return to a relaxed state which is the same or nearly the same as an original resting state. This elastic expansion allows the member  1  to be more easily installed on a penis or a member simulating the penis. 
         [0066]    As shown in  FIGS. 5 and 6 , the member  1  can be capable of being flattened in embodiments. In embodiments, the member  1  is capable of assuming an original state after the force(s) causing the flattening shown in  FIGS. 5 and 6  are removed, i.e., the member  1  has memory which allows it to deflect elastically and thereafter return to a relaxed state which is the same or nearly the same as an original resting state. This flattening allows the member  1  to be more easily packaged. 
         [0067]    As shown in  FIG. 7 , the member  1  can be capable of being folded over in embodiments. In embodiments, the member  1  is capable of assuming an original state after the member  1  is folded as shown in  FIG. 7 , i.e., the member  1  has memory which allows it to deflect and bend elastically and thereafter return to a relaxed state which is the same or nearly the same as an original resting state. This allows the member  1  to be more easily installed on a penis or a member simulating the penis. 
         [0068]      FIGS. 8-10  show one non-limiting way in which the member  1  of  FIGS. 1-7  can be installed on a penis. In  FIG. 8 , the member  1  is shown in a folded back configuration and is ready to be installed on a penis P—which is schematically shown in the right side. The penis P has a head portion HP, a shaft portion SP and a base portion BP.  FIG. 9  shows the member  1  partially installed the penis P. This would typically occur after a lubricant is applied to either the inside of the member  1 , i.e., on surface  4 , or to the outside of the penis P (or both) to facilitate installation. In embodiments, the lubricant is a thin fluid type lubricant such as a commercially available personal lubricant, e.g., astroglide. Although not shown, the penis P can have, in embodiments, a condom (not shown) already installed thereon before the member  1  is placed on the penis P in the manner shown in  FIG. 9 . As is shown in  FIG. 9 , the first end  2  of the member  1  is can be placed adjacent to and slightly spaced from the head portion HP of the penis P.  FIG. 10  shows the member  1  fully installed on the penis P. This occurs after the folded-over portion of the member  1  is folded back towards a base portion BP of the penis P. The fully installed position is, in embodiments, one wherein the first end  2  of the member  1  is located at a short but comfortable position behind the head portion HP of the penis P and the second end  3  of the member  1  is located at a short but comfortable position in front of the base portion BP of the penis P. 
         [0069]      FIGS. 11 and 12  show another non-limiting embodiment of the invention. As in the previous embodiment, the device  100  is essentially comprised of a member  101 . The member  101  has first end  102  which is sized and configured to be disposed adjacent a head portion of a penis and a second end  103  which is sized and configured to be disposed adjacent a base portion of a penis. In embodiments, the first end  102  is disposed adjacent a head portion of a penis, but spaced therefrom by a space ranging from about ⅛ inch to about 1 inch, and preferably between about ¼ inch and ½ inch, and the second end  103  is disposed adjacent a base portion of a penis, but spaced therefrom by a space ranging from about ⅛ inch to about 1 inch, and preferably between about ¼ inch and ½ inch. In embodiments, the first end  102  is generally annular and is slightly rounded where in meets the inner surface  104  and where it meets outer surface  105 . In embodiments, the second end  103  is generally annular and need not be rounded where in meets the inner surface  104  and where it meets outer surface  106 . 
         [0070]    In embodiments, the member  101  is a one-piece or integrally formed member. In embodiments, the member  101  is made of any of the materials used in the previously described embodiment. In embodiments, the member  101  is made of an elastically expandable material and/or capable of being of assuming at least one folded configuration as will be described below. In embodiments, the member  101  has the configuration shown in the drawings when made, has an amount of rigidity which allows it to assume the configuration shown in the drawings when a cylindrical shaft is inserted within the member  101  and having an outside diameter which matches that of the inside diameter of the main axial opening, but does not maintain that same shape when the shaft is removed and the member  101  is placed on its side (as shown in  FIG. 11 ), i.e., the member  1  will experience some deflection due to the force of gravity and its own weight. 
         [0071]    The member  101  also has a generally or substantially cylindrical inner surface  104  which defines a main axial through opening and extends along substantially the entire length of the member  104 . This inner surface  104  is sized and configured to be disposed over a shaft portion of a penis and to exert a compressive force thereon so as to create at least a snug fit. This also prevents, reduces or minimizes axial or rotational movement of the member  1  relative to the penis. 
         [0072]    The member  101  further also has plural generally or substantially cylindrical outer surfaces  105 ,  106 ,  108  and  109  which define distinct and separate sections of the member  1 . Section  105  is sized and configured to be disposed adjacent a head portion of a penis, has a uniform but thinner wall thickness, and a predetermined axial length. In embodiments, a wall thickness of section  105  is between about 0.05 inch and about 0.15 inch, and can preferably be about ⅛ inch. Section  106  is sized and configured to be disposed adjacent a base portion of a penis, has a uniform but thicker wall thickness, and a predetermined axial length. In embodiments, the axial length of section  106  is greater than that of section  105 . In embodiments, a wall thickness of section  106  is between about 0.2 inch and about 0.3 inch, and can preferably be about ¼ inch. Section  108  is sized and configured to be disposed intermediate the base and head portions of a penis, has a uniform but intermediate wall thickness, and a predetermined axial length. In embodiments, the axial length of section  108  is less than that of section  106 . In embodiments, a wall thickness of section  108  can preferably be about 7/32 inch. Section  109  is also sized and configured to be disposed intermediate the base and head portions of a penis, has a uniform but intermediate wall thickness, and a predetermined axial length. In embodiments, the axial length of section  109  is less than that of section  106 . In embodiments, a wall thickness of section  109  can preferably be about 3/16 inch. 
         [0073]    The member  101  further also has plural generally or substantially tapered or chamfered outer surfaces  107  which define distinct and separate short transition sections of the member  101 . Each section  107  is sized and configured to provide a short but smooth and comfortable transition between sections  105  and  109 , between sections  109  and  108 , as well as between sections  108  and  106 . In embodiments, an axial length of each section  107  is between about 0.05 inch and about 0.15 inch, and can preferably be about ⅛ inch.
