Sexual stimulation devices and methods

1. A sexual pleasure device comprising:

an elastomeric sleeve including an elongated cavity;

a rigid housing at least partially surrounding the elastomeric sleeve; and

a pressure element disposed proximal to an inner surface of the rigid housing and distal to and operably engaged with the elastomeric sleeve; and

an actuator disposed distal to the rigid housing and connected to the pressure element,

wherein the actuator is operable to control movements of the pressure element, relative to the housing, thereby to apply pressure to the elastomeric sleeve.

2. The sexual pleasure device of claim 1 , wherein the elongated cavity is configured to simulate a vagina.

3. The sexual pleasure device of claim 1 , wherein the rigid housing is approximately cylindrical.

4. The sexual pleasure device of claim 1 , wherein the pressure element is disposed in a discrete region, and wherein the actuator is operable to displace the pressure element, thereby to impose a localized pressure on the elastomeric sleeve.

5. The sexual pleasure device of claim 1 , wherein the actuator is operable to control movements of the pressure element, relative to the housing, thereby to adjust a volume of the elongated cavity.

6. The sexual pleasure device of claim 1 , wherein the actuator is operable to affect a reduction in the volume of the elongated cavity only in a region proximate the pressure element.

7. The sexual pleasure device of claim 1 , wherein the actuator is operable to affect a reduction in the volume of the elongated cavity localized to one side of the cavity.

8. The sexual pleasure device of claim 1 , wherein displacement of the actuator, relative to the rigid housing, within a first region along a length of the elongated cavity effects a reduction in the volume of the elongated cavity in a second region, along the length of the elongated cavity.

9. The sexual pleasure device of claim 1 , further comprising a pivot point about which the pressure element can move.

10. The sexual pleasure device of claim 1 , wherein the pivot point is removable.

11. The sexual pleasure device of claim 1 ,

wherein the elastomeric sleeve includes an opening arranged to accommodate insertion of a male sex organ into the elongated cavity,

wherein the rigid housing comprises:

a first region, along a length of the rigid housing, arranged proximate to the opening; and

a second region, along the length of the rigid housing, associated with a majority of the length rigid housing, and

wherein a cross-sectional area of the first region is larger than a cross-sectional area of the second region.

12. The sexual pleasure device of claim 11 , wherein the actuator defines a control surface, and wherein the control surface is disposed predominately within the second region along a length of the rigid housing.

13. The sexual pleasure device of claim 1 , wherein the elastomeric sleeve comprises an elastomeric gel formed from a mixture of plasticizing oil and a block copolymer, the block copolymer comprising an admixture of (i) a styrene ethylene butylene styrene block copolymer and (ii) a styrene ethylene propylene styrene block copolymer combined in a ratio of approximately 1:4 to 4:1.

14. The sexual pleasure device of claim 1 , wherein the rigid housing includes a grasping region arranged to be grasped by a user for manipulation of the device, and wherein the actuator is disposed within the grasping region.

15. The device of claim 1 wherein the actuator is a manually operable handle.

16. The device of claim 1 further including at least one stanchion disposed between the actuator and the pressure element.

17. The device of claim 16 further including a hole in the rigid housing through which passes said at least one stanchion.

18. The device of claim 1 wherein the pressure element may rotate relative to the housing.

19. A method for providing sexual pleasure, the method comprising: inserting a male sex organ into a cavity of an elastomeric sleeve, the elastomeric sleeve being at least partially surrounded by a rigid housing engaging an actuator disposed distal to the rigid housing and exposed to manual contact to effect movement of a pressure element disposed proximal to the rigid housing and distal to and operably engaged with the elastomeric sleeve, thereby modifying a sensation perceived by the male sex organ.

20. The method of claim 19 , wherein engaging the actuator comprises applying a first force to the actuator, and wherein the first force is applied within a first region along a length of the cavity and a resulting increase in pressure is applied to the male sex organ within a second region, at a distance from the first region, along the length of the cavity.

21. The method of claim 19 , further comprising dynamically controlling the sensation perceived by the male sex organ as a function of time.

22. The method of claim 21 wherein the dynamically controlled sensation is modified contemporaneously at the manual command of the user.

23. The method of claim 19 , further comprising dynamically controlling the sensation perceived by the male sex organ selectively as a function of location along a length of the elastomeric sleeve.

24. The method of claim 23 wherein the dynamically controlled sensation is modified contemporaneously at the command of the user.

25. The method of claim 19 , further comprising dynamically controlling the sensation perceived by the male sex organ as a function of force applied to the actuator.

26. The method of claim 25 wherein the dynamically controlled sensation is modified manually.

27. The method of claim 19 , wherein modifying the sensation comprises increasing a pressure applied to the male sex organ via the elastomeric sleeve at a location proximal to the pressure element.

28. The method of claim 19 , wherein a plurality of sensations may be provided in the absence of linear displacement between the sex organ and the cavity.
