referring now to the drawings , wherein like reference numerals designate corresponding or similar elements throughout the several views , fig1 shows a device for treating urinary incontinence , generally designated at 10 , and the placement of the device 10 in a female urinary tract 12 . one embodiment of the device 10 comprises a single catheter , or other form of housing 14 defining a lumen 16 . the housing 14 incorporates a time - delayed , physiologically - controlled system situated in the lumen 16 of the device 10 between a proximal portion 18 and a distal portion 20 of the device 10 . the physiologically - controlled system allows a user to achieve urinary control . in one embodiment , the device 10 incorporates the teachings of u . s . patent application publication no . 2007 / 0276342 that describes one embodiment of a physiologically - controlled system . however , it is understood that the different embodiments of the present invention , including the housing of a system of valves in a catheter - like housing that allows for convenient user - controlled insertion and removal , as well as positioning completely internal to the body , is unknown in the prior art . the housing 14 , in one embodiment , resembles a self - catheter and may be cylindrical in shape . as shown in fig1 , the housing 14 comprises a flanged proximal portion 18 and a foley balloon 22 at the distal portion 20 . the device 10 may be positioned in the user &# 39 ; s urethra 24 with a distal end 28 situated internal to the bladder 26 and extending the length of the urethra 24 such that a proximal end 32 of the flanged proximal portion 18 is external to the outside of the body . the housing 14 may be comprised of different materials or vessels that will house a physiologically - controlled system and function similarly while delivering the same benefits to the user . the physiologically - controlled system is activated by the user to regulate the flow of urine through the lumen 16 of the device 10 . in one embodiment , a plurality of valves such as check valves may be centrally mounted within the device lumen 16 and arranged in a linear fashion in series , equally distanced from the distal end 28 to the proximal end 32 . each valve of the plurality of valves is specifically calibrated to the cracking pressure of the human anatomy during stress and normal voiding situations so that optimal urinary retention is achieved . users may initiate opening of individual valves within the physiologically - controlled system through a valsalva maneuver with the user applying physiological pressure to the device 10 of the present invention for a period of approximately 2 - 3 seconds . voiding of the bladder 26 follows as urine enters the device 10 from the bladder 26 through one or more openings in the distal portion 20 and flows through the device lumen 16 causing one or more of the valves to open sequentially . the voiding process is concluded as urine exits the lumen 16 at the proximal portion 18 of the device 10 , externally situated outside of the body . once the flow of urine ceases and the user releases pressure , the valves will revert to the closed position . the physiologically - controlled system as a whole will remain closed until the user once again directly applies a short duration (˜ 2 - 3 seconds ) of pressure . the device 10 may be secured in the bladder 26 at the distal end 28 by means of the foley balloon 22 that , when inflated , rests at the top of the urethra 24 as illustrated in fig1 . once balloon 22 inflation is achieved the device 10 is secured from easily exiting the bladder 26 and moving proximally out of the urethra 24 during unintended exertions of abdominal pressure or movement . the device 10 is further secured by the housing , which in this embodiment includes the flanged proximal portion 18 such that the shape of the proximal end 32 provides resistance against undesired inward movement of the device 10 through the urethra 24 and into the bladder 26 as may be caused by user movement or activity . together the foley balloon 22 and the flanged proximal portion 18 secure the device 10 in place throughout usage . a tube or similar infrastructure ( not shown ) lines the interior of the device 10 from the proximal portion 18 to the distal portion 20 and provides a fluid carrying and delivery means for the balloon &# 39 ; s 22 inflation and deflation mechanism . the tube has a circular or oval outlet at the proximal end 32 of the device 10 that allows for the insertion of a fluid delivery mechanism . in one embodiment , the fluid is water or other sterile solution , and the delivery mechanism is a syringe that is operated by the user of the device 10 . to inflate the balloon 22 , the user inserts the syringe into the outlet and deploys the syringe thereby releasing the water contained within . the water then travels through the tube to the foley balloon 22 until inflation is achieved . the water remains in the foley balloon 22 until the user decides to remove the device 10 from the urethra 24 . to deflate the balloon 22 , the user again inserts the syringe into the outlet at the proximal end 32 of the device 10 and removes the water by retracting the loading piece of the syringe or by merely allowing the pressure contained in the balloon 22 to passively deflate the fluid from the balloon 22 . once balloon 22 deflation is achieved , the user can remove the device 10 by simply grasping and pulling on the flanged proximal portion 18 of the device 10 until it is completely withdrawn from the urethra 24 . fig2 shows another embodiment of a device for treating urinary incontinence , generally designated at 40 . in this embodiment , the device 40 may be positioned in the user &# 39 ; s urethra 24 with a distal end 42 situated in the urethra that does not extend to the bladder 26 , and a proximal portion 44 extending the length of the urethra 24 external to the outside of the body . the device 40 , in form and function , can be similar to the previously described embodiment . the methods to secure the device 40 may be different in this embodiment , as is insertion and removal , which may include but are not limited to , an external balloon , being conically shaped , having the device attach to an external article of clothing , etc . thus , fig2 shows an embodiment of the device 40 whereby the positioning and securing of the device 40 can be changed to achieve optimal urinary retention and user control . fig3 shows another embodiment of a device for treating urinary incontinence , generally designated at 50 . in this embodiment , the device 50 may be positioned in the user &# 39 ; s urethra 24 and extends the length of the distal region of the urethra and such that the distal end 52 of the device 50 enters the bladder 26 . the device 50 is sized so that the proximal portion 54 does not extend to the urethral meatus 56 or external to the outside of the body . the device 50 , in form and function , can be similar to the previously described embodiments . the methods to secure the device 50 may be different in this embodiment , as is insertion and removal , which may include but are not limited to a collapsible component that , when collapsed , can traverse the urethra 24 but that then deploys to a larger diameter inside the bladder 26 , a mechanism that is deployed outward once placed into the bladder 26 , etc . fig4 shows another embodiment of a device for treating urinary incontinence , generally designated at 60 . in this embodiment , the device 60 may be positioned in the user &# 39 ; s urethra 24 and extends the length of the urethra , but the device 60 is sized so that the ends of the device 60 do not extend beyond the urethral meatus 56 or enter into the bladder 26 . the device 60 , in form and function , can be similar to the previously described embodiments . the methods to secure the device 60 may be different in this embodiment , as is insertion and removal , which may include but are not limited to , having a conical shape , having a temporary adhesive ( such as a biodegradable glue ), having an external component of the device that grips the urethra , etc . in practice , the embodiments of the device 10 , 40 , 50 , 60 as described herein are intended for short term usage and may be replaced regularly to prevent against or minimize infections in the urethra . the embodiments of the device 10 , 40 , 50 , 60 are intended to be reused for a period of 1 to 2 weeks , although optimal usage time is expected to be determined on a case - by - case basis by a practitioner .
a short term usage device is provided for treating urinary incontinence . the device may extend the length of the urethra from internal to the bladder to external to the outside the body . a proximal component , when external to the body , prevents the device from leaving the urethra and entering into the bladder and prevents the device from leaving the urethra and exiting the body . a distal component , when internal to the bladder , prevents the device from leaving the urethra and exiting the body and prevents the device from leaving the urethra and entering into the bladder . the device is configured with a mechanism to regulate urine flow using physiologically created pressures that are applied to the distal portion of the device .
