Abstract
An inflatable vaginal pessary of the invention, which can be mechanically inserted into and removed from the patient's vagina, comprises a tapered body inflatable at its large-diameter side and having an axial channel inflation of the pessary. This channel passes from the small-diameter end to the inflatable chamber and has a check valve at the outer end of the channel for inflation of the pessary. The pessary can be connected to and disconnected from a mechanism for insertion and removal of the pessary into and from the vaginal cavity. This mechanism has a hollow tubular housing with a funnel-like finder for engagement with the tapered end of the pessary. On the bottom of the finder the pessary installation mechanism has a threaded tubular stem that could be screwed into the threaded opening on the tapered end of the pessary. On the proximal end the mechanism has a pumping bulb for inflating the pessary via the check valve by squeezing the bulb, in the same manner as inflation of the occlusive cuff in a manually-operated blood-pressure measuring apparatus. The pessary of the invention can be easily installed into the patient's vagina by the patient herself. For this purpose, the pessary is connected to the aforementioned mechanism, inserted by the patient into an appropriate position inside her vagina, inflated to a required degree in order to fix the pessary in place, and is then disconnected from the mechanism for use during the day. In its inflated state with an increase diameter the pessary compresses the urethra through the vaginal wall and thus reduces the cross section of the urethral lumen. At the end of the day before the bed time, the patient easily reconnects the mechanism to the pessary, deflates the pessary, and removes the latter by means of the same mechanism.
Description




TECHNICAL FIELD




The present invention relates to an inflatable vaginal pessary suitable for treating urinary incontinence, cystoceles, rectoceles, enterocelles, and uterine prolapse. The invention also relates to a method for installation and removing of the aforementioned inflatable pessary.




BACKGROUND




Continence, or normal control of urine retention in the bladder, involves the coordination of the bladder, bladder neck and urinary sphincter. The body stores urine in the bladder by maintaining a closed bladder neck and a contracted urinary sphincter muscle. To pass urine the bladder contracts while the bladder neck opens and the urinary sphincter muscle relaxes.




Urinary incontinence (UI) occurs when one or more of the anatomical structures related to urine storage malfunctions and leads to a loss of control of urination. The most common type of incontinence is caused by hypermobility of the bladder neck and urethra due to weakening of the tissues surrounding these structures. In females, pelvic trauma associated with child birth is a common cause of tissue weakening. Another cause of incontinence is a deficiency in urinary sphincter muscle control, intrinsic sphincter deficiency (ISD). It is estimated that approximately 8.5 million women suffer from UI in the United States. Up to 75% of female nursing home patients experience some degree of urinary incontinence, creating a tremendous economic, as well as hygienic, burden.




Female incontinence is currently treated using behavioral techniques, various devices, surgical techniques, and pharmaceuticals. Among devices widely used for alleviating the above problem, a device, which is known as pessary, is a useful alternative or an adjunctive aid rather than a substitute for gynecological surgery. A pessary is a device, which is inserted into the vagina for controlling uterine prolapse, uterine retrodisplacement, or stress urinary incontinence via the walls of the vagina.




A great variety of vaginal pessary device is known and is available on the market. Some pessaries are made in the form of a rigid, i.e., non-inflatable rings, dishes, hodges, donuts, etc. Such devices are produced, e.g., by Millex Products, Inc., Chicago, U.S.A. The aforementioned pessaries are inserted and removed manually which present a problem for inserting and removing by the patient. Insertion and removal of such pessary by the doctor or nurse is easy in most cases. In the past, doctors and nurses would fit the patient with a type of pessary, insert it into the patients vagina and leave it there for 3 months. The patient comes back to the doctor's office in 3 months and remove, clean and insert the pessary again or use a new one. But the doctor or nurse always insert and remove the pessary. Such a practice is seldom used now because pessaries left for weeks and months usually cause irritation and infection in the vagina and produce bad odor and significant vaginal discharge. Therefore most doctors and patient have abandoned this method.




The new approach is to use the pessary on a daily basis by having the patient insert the pessary in the morning and removing it in the evening. She cleans the pessary with special solution, and then re-insert it the next morning. This is the same idea as intermittent catheterization that is now done three-four times per day by the patient rather than having an indwelling Foley catheter in the bladder for usually four weeks, and the doctor insert and remove the catheter.




The problem with this new method of daily insertion and removal is that the patient has to learn how to insert and remove the pessary herself. However, as has been mentioned above, the aforementioned rigid pessaries are difficult to insert and likewise, very difficult to remove by the patient.




Attempts have been made to solve the above problem by providing an inflatable pessary consisting of a donut-type inflatable portion which is manually inserted into the vagina and which is connected via a flexible tube with an externally located pumping bulb. The donut portion is individually fitted and adjusted into a required place of the vagina and then is inflated to a proper size by means of the pumping bulb via the flexible tube. The donut portion is provided with a check valve for maintaining the pessary in an inflated state. Upon completion of inflation, the bulb is disconnected leaving a short piece of the flexible tube protruding out from the vagina, so that this protruding end can then be used for removing the inflated donut portion of the pessary from the vagina. Such a device is also produced by Millex Products, inc., Chicago, U.S.A. A disadvantage of this device is that it is still manually inserted and that the end of the flexible tube protruding from the vagina creates discomfort for the patient. Another disadvantage is that the donut portion is removed in an inflated state.




U.S. Pat. No. 5,611,768 issued in 1997 to R. Tutrone discloses a pessary device comprising two sequentially arranged inflatable chambers, one of which is placed into the anterior part of the vaginal cavity and another to the posterior part of the vaginal cavity. Both chambers are inflated separately via separate valves located outside the vagina and remaining attached to the device after the inflation. At least one of the chambers is intended for pressing via the vaginal wall on the urethra thus combating female incontinence.




This device entails the same disadvantages as the previously described pessaries, i.e., the pessary removing means remain permanently attached to the pessary. Another disadvantage is that this device has a complicated construction. It has top be manually inserted and removed.




OBJECTS OF THE INVENTION




It is an object of the invention to provide a mechanically insertable and removable inflatable vaginal pessary which is easily insertable and removable by a patient, which is disconnected from the insertion and removal device after inflation and during the use of the pessary, and which can be easily reconnected to the aforementioned device, and can be adjusted to a required position within the patient's vagina. It is another object to provide a mechanical device, which is connectable to a pessary for its insertion, disconnectable from the inserted pessary after insertion, and reconnectable for removal of the pessary for replacement. It is a further object to provide the aforementioned mechanical device with means for inflation and deflation of the inflatable pessary. Another object is to provide a method for easy and reliable insertion of the pessary by the patient herself.




SUMMARY OF THE INVENTION




An inflatable vaginal pessary of the invention, which can be mechanically inserted into and removed from the patient's vagina, comprises a tapered body inflatable at its large-diameter side and having an axial channel for inflation of the pessary. This channel passes from the small-diameter end to the inflatable chamber and has a check valve at the outer end of the channel for inflation of the pessary. The pessary can be connected to and disconnected from a mechanism for insertion and removal of the pessary into and from the vaginal cavity. This mechanism has a hollow tubular housing with a funnel-like finder for engagement with the tapered end of the pessary. On the bottom of the finder the pessary installation mechanism has a threaded tubular stem that could be screwed into the threaded opening on the tapered end of the pessary. On the proximal end the mechanism has a pumping bulb for inflating the pessary via the check valve by squeezing the bulb, in the same manner as inflation of the occlusive cuff in a manually-operated blood pressure measuring apparatus. The pessary of the invention can be easily installed into the patient's vagina by the patient herself. For this purpose, the pessary is connected to the aforementioned mechanism, inserted by the patient into an appropriate position inside her vagina, inflated to a required degree in order to fix the pessary in place, and is then disconnected from the mechanism for use during the day. In its inflated state with an increase diameter the pessary compresses the urethra through the vaginal wall and thus reduces the cross section of the urethral lumen. At the end of the day before the bedtime, the patient easily reconnects the mechanism to the pessary, deflates the pessary, and removes the latter by means of the same mechanism.

DETAILED DESCRIPTION OF THE INVENTION




A method of the invention comprises the steps of: providing an inflatable vaginal pessary, which has an inflatable portion with a check valve, a tapered guide portion with connection means, and a pessary insertion/removal device; connecting the aforementioned device to the aforementioned connection means of the pessary in a deflated state, when its inflatable portion has a reduced diameter; inserting the pessary into the patient's vagina; inflating the pessary within the vagina so as to fix it in place; disconnecting the pessary insertion/removal device from the pessary; maintaining the pessary within the vagina for a required period of time; connecting the aforementioned device to the aforementioned connection means of the pessary; deflating the inflatable portion by acting with the aforementioned device on the check valve of the pessary, thus reducing the diameter of the inflatable portion; removing the pessary from the vagina; and disconnecting the used pessary from the device for discarding.




An inflatable vaginal pessary for realization of the method of the invention is shown in

FIG. 1

, which is a longitudinal sectional view of the device. As can be seen from this drawing, the pessary consists of a donut-like hollow inflatable portion


12


, shown by solid lines in an inflated form and by dash-and-dot lines in its inflated form, and a tapered guide portion


14


projecting from the inflatable portion


12


. The tapered guide portion


14


has a longitudinal channel


16


, which is open to the atmosphere at one end and is connected to the hollow inflatable portion


12


at the other end via transverse channels


18


and


20


. It can also be seen that in the embodiment shown in

FIG. 1

the tapered guide portion


14


of the vaginal pessary


10


has a round cross section.




At the end opposite to the inflatable portion


12


the longitudinal channel


16


has a threaded portion


19


, and a spring-located ball


21


which is located in a tapered expansion


23


of the channel


16


is permanently urged by a spring


25


toward the threaded end of the channel


16


for normally closing the channel. The spring-loaded ball


21


forms a check valve which allows admission of the pressurized fluid into the channel for inflation of the inflated portion


12


but prevents the escape of pressurized fluid from the inflated pessary. On the side opposite to the tapered guide portion


14


, the inflatable portion


12


is fit onto a bobbin-like end


22


of the tapered portion which has a recess


24


for engagement with neck of the uterus U when the pessary is installed and fixed in the vagina V in the operating position, as shown in FIG.


2


.





FIG. 3

is a longitudinal sectional view of the inflatable pessary of

FIG. 1

connected, prior to insertion into the patient's vagina, to a mechanical pessary insertion/removal device


30


. The insertion/removal device


30


has a hollow tubular housing


32


with a longitudinal central opening


34


and a funnel-like pessary finder


36


on the end of the housing


32


that faces the pessary


10


. On the finder side, the central opening


34


is closed with an end wall


38


, which forms the bottom of the funnel-like finder


36


. A threaded tubular stem


40


, which has an external thread


42


, extends from the outer side of the end wall


38


for engagement with the thread


19


at the end of the longitudinal channel


16


of the pessary


10


. The length of the threaded tubular stem


40


is greater than the distance from the front end of the tapered portion


14


of the pessary to the spring-loaded ball


21


in it normal position. It is recommended that the threaded stem


40


and the threaded opening


19


have non-locking thread, which could be easily disconnected and reconnected without application of a noticeable torque.




At the end opposite to the finder


36


, the tubular housing


32


of the insertion/removal device


30


has a flange


42


for use as a handle for connecting the device


30


to the pessary by screwing the threaded stem


40


into the threaded opening


19


of the pessary


10


. On the flanged side, the housing


32


has a pumping bulb


44


made of a resilient material such as rubber for inflating the pessary


10


via the check valve of the pessary


10


formed by the spring-loaded ball


21


by squeezing the bulb


44


, in the same manner as inflation of the occlusive cuff in a manually-operated blood-pressure measuring apparatus. The bulb


44


can be easily removed or connected by fitting onto spherical or similar head


46


with a through opening


47


connected to the central opening


34


of the housing


32


. Reference numeral


45


designates a check valve in the bulb


44


for admission of air from the surrounding atmosphere when the bulb is released after being squeezed for pumping the inflatable portion of the pessary.




In order to ensure that the valve formed by the ball


21


is closed when the device


30


is connected to the pessary


10


prior to insertion into the patient's vagina, the pessary


10


may have a mark


48


on the outer surface of the tapered portion


14


for discontinuing rotation of the flange


42


when the front end of the finder


36


is aligned with the position of the mark


48


. The same mark


48


can be used for deflation of the inflated portion


12


of the pessary prior to removal of the pessary from the vagina.




The device of the embodiment shown in

FIGS. 1

,


3


and


4


operates as follows. Prior to insertion of the pessary into the patient's vagina, the pessary


10


, with an inflatable portion


12


in its deflated form shown by solid lines in

FIG. 1

, is attached to the pessary insertion/removal device


30


by screwing the threaded stem


40


of the device


30


into a threaded opening


19


of the pessary. This operation is performed by inserting the tapering end


14


of the pessary


10


into the tapered opening of the funnel-like finder


36


so that the threaded stem


40


of the device


30


is aligned with the threaded opening


19


, and then the stem


40


is screwed into opening


19


by rotating the device


30


with the use of a flange. The rotation is continued until the front end of the finder


36


is aligned with the matching mark


48


on the tapered portion


14


of the pessary


10


. When rotation of the device


30


is discontinued in the position of alignment of the mark


48


with the end of the finder


36


, the user of the device can be sure that the connection between the pessary


10


and the device


30


is sufficiently strong and that the check valve formed by the spring-loaded ball


21


is closed.




The pessary


10


supported by the device


30


is then easily inserted into the patient's vagina and adjusted to an appropriate position. The pessary is then inflated by periodically squeezing and releasing the pumping bulb


44


. When the bulb is squeezed, the air which is entrapped in the bulb


44


and in the central axial opening


34


of the housing


32


is displaced under pressure towards the vaginal pessary


10


and lifts the ball


21


against the force of the spring


23


. The air is then pumped into the inflatable portion


12


of the pessary


10


via the threaded opening


19


, axial channel


16


, and transverse channels


18


. As a result, the inflatable part


12


of the pessary is inflated, its diameter is increased, and it assumes the form shown in

FIGS. 1 and 4

by dash-and-dot lines. Due to an increased diameter, the pessary is fixed in the vaginal V in the selected position, e.g., as shown in FIG.


7


. In its inflated state with an increase diameter the pessary compresses the urethra through the vaginal wall and thus reduces the cross section of the urethral lumen to the point where no urine leaks out during movement. Within the vagina V, the tapered portion


14


of the pessary


10


is directed towards the vaginal entrance.




Since the pessary


10


is fixed within the vagina V, the insertion/removal device


30


can be separated. For this purpose, the threaded stem


40


is unscrewed from the threaded opening


19


of the pessary by rotating the device


30


with the use of the flange


42


as a handle. Since the stem


40


and the opening


19


have non-locking thread, the device


30


can be disconnected from the pessary


10


fixed in the vagina without a noticeable effort, so that disconnection of the device


30


will not violate position of the pessary in the vagina V.




At the end of the day before the bed time, the patient easily reconnects the mechanism to the pessary


10


by inserting the device


30


into the vagina V so that the funnel-like finder


36


is fit onto the tapered portion


14


of the pessary and is then connected thereto by screwing the threaded stem


40


into the threaded opening


19


of the pessary


10


. The flange


42


is rotated until the front edge of the device


30


overlaps the position of the mark


48


so that the end of the stem


40


pushes the ball


25


against the force of the spring


25


, whereby the air is released from the inflated portion


12


of the pessary


10


via the channels


18


,


20


, channel


16


and a gap between the now lifted ball


21


and the open end of the threaded opening


19


. After deflation, the diameter of the inflatable portion


12


is reduced to the condition shown by the solid lines in

FIGS. 1 and 4

, so that the pessary


10


, which is now connected to the device


30


, can be easily withdrawn from the vagina V.





FIGS. 5 and 6

illustrate another embodiment of the vaginal pessary and the pessary insertion/removal device.

FIG. 5

is a longitudinal sectional view of a modified inflatable pessary connected to a pessary insertion/removal device made in accordance with another embodiment of the invention.

FIG. 6

is a sectional view along line VI—VI of FIG.


5


.




Since in general the pessary and the pessary insertion/removal device of this embodiment are similar to those of the previous embodiment, the parts of the embodiment of

FIGS. 5 and 6

identical to those shown in

FIGS. 1-4

will be designated by the same reference numerals with an addition of


100


. Furthermore, the description of identical parts and elements will be omitted.




A pessary


110


of the embodiment of

FIGS. 5 and 6

differs from the one shown in

FIGS. 1-4

only by the non-round cross section of the tapered portion


114


of the pessary


110


. As can be seen from

FIG. 6

, in the illustrated embodiment the tapered portion


114


has a hexagonal shape. The device


130


is in general similar to the device


30


of the previous embodiment and differs from it in that the finder portion


136


is separated from the hollow tubular housing


132


and is formed on the end of an outer housing


150


which faces the tapered portion


114


of the pessary


110


. The opening of the funnel-like finder


136


has the same non-round cross section as the tapered end


114


of the pessary


110


, which is hexagonal in this embodiment. The hollow threaded stem


140


is formed on the closed front end of the tubular housing


132


which is telescopically inserted into the outer housing


150


. The rest of the device remains the same as in the previous embodiment.




In use, prior to insertion, the device


130


is connected to the pessary


110


by inserting the tapered portion


114


into the finder


136


. Since the tapered end


114


of the pessary


110


and the opening of the finder


136


have mating hexagonal profiles, the finder


136


will fit onto the tapered end as an Allen wrench is fit onto the hexagonal head of the bolt, so that the relative rotation between the pessary


110


and the outer housing


150


is prevented. By holding with one hand the pessary


110


and the outer housing


130


in the region of the finder


136


, the stem


140


is screwed into the threaded opening


119


of the pessary by rotating the flange.




The flange is rotated until a small gap G, e.g., of about 2 to 5 mm remains between the front edge of the flange


142


and the rear end face of the outer housing


150


. A provision of this gap guarantees that the end of the stem did not lift the ball


121


against the force of the spring


125


.




The pessary


110


, which is a deflated state, is inserted into the patient's vagina, is inflated in the same manner as in the previous embodiment, and is then easily disconnected by rotating the flange


142


in the direction of unscrewing the stem


140


from the threaded opening


119


.




For removal of the pessary


110


from the patient's vagina, the profiled finder


136


is fit onto the profiled tapered end


114


of pessary


110


so that the pessary cannot be rotated with respect to the outer housing


150


. The outer housing


150


is held with one hand of the user and the flange


142


is then rotated by another hand of the user in the direction of screwing the threaded stem


140


into the threaded opening


119


. The flange


142


is rotated until its front surface comes into contact with the rear end face of the outer housing


150


so that no gap G is left between both parts. Under these conditions, the front end of the hollow threaded stem


140


lifts the ball


121


against the force of the spring


125


, whereby air is released from the inflated portion


112


of the pessary


110


. In a deflated state, the pessary


110


is removed from the vagina by withdrawing the device


130


from the vagina together with the reconnected pessary


110


.




Thus it has been shown that the invention provide an inflatable vaginal pessary which can be easily inserted into and removed from the patient's vagina without the use of fingers but with the use of a simple mechanical device by a patient herself, which is disconnected from the device after inflation and during the use of the pessary, which can be easily reconnected to the pessary removing device, can be adjusted to a required position within the patient's vagina, can be connected to a mechanical device for its insertion and removal. The invention also provides a method for easy and reliable insertion of the pessary by the patient herself.




Although the invention has been shown and described with reference to specific embodiments, it is understood that these embodiments should not be construed as limiting the application of the invention, so that any changes and modifications are possible, provided they do not depart from the scope of the patent claims. For example, the pessary may be made without the recess on the front side of the inflatable portion, the tapered guide portion of the pessary may have a square, triangular, hexagonal, splines, or any other cross-section. The housing of the pessary insertion/removal device may have any modified shape and made of biologically-acceptable plastic or metal. The device can be connected to the pessary by having a thread on the outer side of the tapered portion and on the inner surface of the finder, while the ball of the check valve is lifted by a non-threaded stem.
