Sexual Stimulation Devices and Methods

Abstract

A sexual stimulation device includes an elongated dildo housing sized to be received within an orifice of a human body, the housing defining an internal cavity extending along a longitudinal axis of the housing, a mass laterally constrained within the cavity and movable linearly along the cavity, and an electrically driven actuator disposed within the housing and operably coupled to the mass. The actuator is operable to accelerate the mass along the cavity and to thereby induce a longitudinal reactive acceleration of the housing.

1 . A sexual stimulator, comprising:
 an elongated housing sized to be received within an orifice of a human body, the housing defining an internal cavity extending along a longitudinal axis of the housing;   a mass laterally constrained within the cavity and movable linearly along the cavity; and   an electrical actuator operably coupled to the mass, the actuator operable to accelerate the mass with a non-rotational, linear reciprocal motion along the cavity and to thereby induce a longitudinal acceleration of the housing.   
     
     
         2 . The stimulator of  claim 1 , wherein the housing comprises a flexible sheath overlaying a structural member. 
     
     
         3 . The stimulator of  claim 1 , wherein the actuator comprises a linear motor. 
     
     
         4 . The stimulator of  claim 1 , wherein the actuator comprises an electromechanical solenoid. 
     
     
         5 - 8 . (canceled) 
     
     
         9 . The stimulator of  claim 1 , further including a lateral mass displaceable with respect to the housing only in a direction substantially perpendicular to the longitudinal axis. 
     
     
         10 . The stimulator of  claim 1 , wherein the actuator comprises a rotary motor coupled to a transmission that converts rotary motor armature motion to linear mass motion. 
     
     
         11 - 16 . (canceled) 
     
     
         17 . The stimulator of  claim 1 , further comprising a signal receiver connected to the actuator and responsive to a control signal from a remote operator. 
     
     
         18 - 19 . (canceled) 
     
     
         20 . The stimulator of  claim 1 , further comprising a handle disposed at one end of said housing, and an isolator connecting the housing and handle. 
     
     
         21 . The stimulator of  claim 20 , wherein the housing is slidably coupled to the handle. 
     
     
         22 . The stimulator of  claim 1 , wherein the actuator is operable to induce an overall longitudinal motion of the stimulator, the induced overall motion having an amplitude of at least 4 mm. 
     
     
         23 . The stimulator of  claim 1 , wherein the actuator is operable to induce an overall longitudinal motion of the stimulator with an amplitude at least 10 times greater than an amplitude of any lateral motion of the stimulator induced by actuator operation. 
     
     
         24 . (canceled) 
     
     
         25 . A method of creating sexual stimulation, the method comprising
 bringing the stimulator of  claim 1  into contact with a sexual organ; and   holding the stimulator in contact with the sexual organ while the actuator is operated to move the mass along the cavity.   
     
     
         26 . A sexual stimulator, comprising:
 an elongated housing sized to be received within an orifice of a human body, the housing defining an internal cavity extending along a longitudinal axis of the housing;   a mass laterally constrained within the cavity and movable linearly along the cavity;   an electric actuator disposed within the housing and operable to accelerate the mass along the cavity; and   a controller configured to control motion of the mass according to a preset motion profile including a first acceleration rate in a first direction along the longitudinal axis, and a second acceleration rate in a second direction along the longitudinal axis, the second acceleration rate differing from the first acceleration rate.   
     
     
         27 . The stimulator of  claim 26 , wherein the housing comprises a flexible sheath overlaying a structural member. 
     
     
         28 . The stimulator of  claim 26 , wherein the actuator comprises a linear motor. 
     
     
         29 . The stimulator of  claim 26 , wherein the actuator comprises an electromechanical solenoid
