Definitions

  • the present invention relates to an intravaginal device comprising components capable of being distended to engage vaginal walls during use and then contracted prior to its removal .
  • Intravaginal devi-ces for managing bodily fluids are known in the art. Two major uses are known: managing discharged bodily fluids, such as menses, and support of the urinary system, such as "pessaries" . Devices for managing bodily fluids generally fall into two main categories.
  • the first category consists of one or more absorbing bodies such as tampons containing absorbent material .
  • tampons containing absorbent material .
  • Tampons are typically manufactured from a web of absorbent fibers and compressed into a cylindrical form for inserting into a user's vaginal canal, either digitally or with the assistance of an applicator.
  • the second category of intravaginal devices known in the art consists of collecting devices, such as those disclosed in Zoller, US Pat. No. 3,845,766 and Contente et al., US Pat. No. 5,295,984. Collection devices are designed to assume a normally open, concave configuration, with an open side facing a user's cervix. The collection devices may be folded, or otherwise manipulated, to facilitate insertion into the vaginal canal.
  • the first method disclosed consists of pulling on an attached removal means, such as a string, sufficient to decrease a transverse diameter of the balloon.
  • the second method employs microporous material for constructing the balloon. This allows air to escape at a substantially predetermined time following inflation of the distensible member.
  • Zadini et al . , PCT Pub. No. WO 99/07433 discloses an intravaginal balloon for blood leakage prevention.
  • a method of deflating the intravaginal balloon consists of creating a slit in a chamber wall of the balloon with the removal string, thereby providing an escape route for carbon dioxide or suitable inflating gas.
  • DEKA Products Limited Partnership discloses a catamenial collector having a receptacle with a flexible hollow rim capable of inflation. The device employs tear marks along portions of a handle extending from the receptacle, whereby portions of the device can be torn away, allowing for deflation prior to removal.
  • the gas that escapes from the inflatable portion is not assuredly directed outside of the body. Indeed, in one or more of the Zadini embodiments, the gas may be discharged directly into the vagina.
  • the gas may be discharged directly into the vagina.
  • Osborn et al . , WO 98/41179 suggests that the presence of excessive amounts of gas, including oxygen and carbon dioxide , in the vaginal canal may be undesirable. Therefore, it is desirable to ensure that discharges of such gases into the vagina is prevented.
  • the inflatable devices that are pumped from the atmosphere may allow the user to over- inflate the devices with dangerous consequences. Therefore, what is needed is a distensible intravaginal device that prevents discharge of potentially dangerous gases into the user's vagina and that safely limits the distension of any insertable reservoir.
  • an intravaginal catamenial device comprising an distensible member and a single valve, the valve capable of repeated two-way fluid communication providing a means for both inflation and deflation of the device.
  • the present invention relates to a device for insertion into a body cavity having a wall .
  • the device includes an insertable reservoir that is capable of being inserted into the body cavity and distending to engage the wall of the body cavity.
  • An external reservoir is in fluid communication with the insertable reservoir through a conduit.
  • There is a valve associated with the conduit that is capable of alternately preventing and allowing fluid to flow, via the conduit, from the external reservoir to the insertable reservoir and from the insertable reservoir to the external reservoir, as desired by a user.
  • the device contains a predetermined quantity of a working fluid.
  • the device may be used intravaginally as a catamenial device or as a urinary system support.
  • the device may be useful if dimensioned to fit within a user's urethra to block unwanted urinary discharge.
  • the invention also relates to a method for controlling the passage of bodily discharges from a body cavity having a wall.
  • the method includes inserting an insertable reservoir into the body cavity; transferring a quantity of fluid from an external reservoir into the insertable reservoir via a conduit; distending the insertable reservoir to engage the wall of the body cavity; operating a valve to maintain fluid in the insertable reservoir; operating a valve to permit transfer of a quantity of fluid from the insertable reservoir to the external reservoir via the conduit; and removing the insertable reservoir from the body cavity. This may be repeated, as necessary, to meet the needs of the user.
  • the method may relate to managing bodily fluids during a period of menstruation.
  • Such a method may include the steps of inserting a catamenial device into a vaginal canal, having a wall, transferring fluid from the external reservoir into the insertable reservoir, the amount of fluid being sufficient to distend the insertable reservoir to cause it to engage the wall of the vaginal canal; maintaining the insertable reservoir in the vaginal canal for preventing passage of the bodily fluids from the vaginal canal for a duration of at least 2 hours; transferring fluid from the insertable reservoir to the external reservoir; and removing the insertable reservoir from the vaginal canal .
  • a device useful in this method has an insertable reservoir that is capable of being inserted into the vaginal canal and distending to engage the wall of the vaginal canal, an external reservoir, and a conduit providing fluid connection between the reservoirs .
  • the insertable reservoir has a cervix-facing side and an opposing side, and a valve capable of alternatively preventing and allowing fluid to flow, via the conduit, from the external reservoir to the insertable reservoir and from the insertable reservoir to the external reservoir, as desired by a user, is associated with the conduit.

  • a first valve 30a would operate to maintain fluid in the insertable reservoir 20
  • a second valve 30b would operate to maintain fluid in the external reservoir 22.
  • the device 10 could then be manipulated, e.g., by compressing the external reservoir 22 and opening the second valve 30b to direct fluid from the external reservoir 22, through the conduit 24, and into the insertable reservoir 20.
  • the first valve 30a would then keep the fluid in the insertable reservoir 20 (again, as shown in FIGS. 3 or 4) .
  • a manipulable valve may also require appropriate environmental properties.
  • environmental properties relates to the condition or circumstances corresponding to the materials or elements of the device surrounding the valve. This includes, but is not limited to, physical properties of the valve housing and valve placement within the housing, such as depth. For example, if a duckbill valve resides within a fluid conducting conduit, then the conduit must be sufficiently flexible and resilient, in at least portions proximal the duckbill valve, so as to permit transfer of compressive forces applied to the outer surface of the conduit, to open the normally closed sealing lips. Upon release of the compressive forces, any environmental changes, such as distortion of the conduit in areas proximal the valve dissipates, due to its resiliency. This dissipation allows for repeated manipulation of valves used in the present invention.

Abstract

L'invention concerne un dispositif intravaginal cataménial comportant un élément gonflable destiné à coopérer de manière étanche les parois du vagin. Le gonflement de cet élément permet d'obtenir une expansion immédiate après introduction dans le vagin, ce qui permet de minimiser la possibilité d'une fuite secondaire de fluides corporels. Le dispositif de l'invention utilise un mécanisme de valve capable d'établir une communication fluidique bidirectionnelle qui permet de gonfler et de dégonfler ledit dispositif. L'élément gonflable peut présenter toute forme utile pour bloquer et/ou collecter des fluides corporels.
