An implantable urodynamic system includes an implantable first device deployable in a patient's bladder, an implantable second device deployable in a patient's vaginal canal, and a data acquisition and analysis module or processing unit external to the body of the patient. The first device includes a magnet and an inductive coil, and the second device includes a magnet, an inductive coil and a battery. When deployed in the patient's body, attraction between the magnets maintains the two devices in close proximity to one another to effect an inductive coupling between the coils so that the first device may be powered by the battery of the second device. The urodynamic system is intended to facilitate measurement, collection, and wireless transmission of real-time, or near real-time, data (bladder pressure, abdominal pressure, and temperature) from an ambulatory patient. This data is of value in diagnosing a number of abnormal bladder conditions, such as infection, overactive bladder, bladder spasms, and the like.

This document provides surgical retractor devices and systems. For example, this document provides a weighted surgical retractor system. In one example embodiment, this document provides a weighted Deaver retractor system that includes a selectable amount of weight that can be releasably coupled to a shaft of the retractor. The surgical retractors provided herein can be used during a variety of surgical procedures, including surgical procedures performed on the abdomen, thoracic regions, limbs, and so on. In some embodiments, the surgical retractors provided herein are well-suited for retraction of the vaginal canal for hysterectomy surgery, and for other procedures for which vaginal retraction is necessary.

The novel idea of the present invention is to fabricate spiral configuration into the annular recessed cylindrical wall around the spray nozzle on the face plate of certain kinds of currently marketed hand-held and wall-mounted showerheads to allow a coupling feature in place for screw-on connection by our specially designed disposable vaginal douche nozzle. The showerhead water flow path for the douche nozzle shares the same water flow path with the spray nozzle. User can access the douche mode by selecting the existing spray mode of the spray nozzle wherein it has a coupling structure attachable to our douche nozzle. The spray pattern of the spray nozzle stays unaffected when our douche nozzle is not attached. In accordance with the present invention, adequate and efficient vaginal deodorization may be accomplished by douching with only normal household water that ensures minimal alteration of vaginal pH while rinsing out the vaginal canal.

A device and method for improving fertility among couples after intercourse is disclosed. The device and method uses an intravaginal device that collects ejaculate from the vaginal canal after intercourse and presents it to the os of the cervix. The device also serves to contain ejaculate near the cervical os to increase the chances of successful fertilization.

Employing the known “tensegrity” principle, a female condom is configured such that when the condom is inserted into a woman's vagina, the woman's introitus acts on a proximal section of an elongated pouch extending between internal and external biasing members (e.g., rings) of the condom. Inward compressive forces exerted by the introitus on the inner ring of the condom cause the inner ring to be pushed distally within the vaginal canal, and the proximal pouch section to become a tension member pulling against the external ring. This causes a “tenting” of the proximal pouch section against the introitus. The resulting interaction of compression and tensile forces (a tensegrity effect) serves to provide the condom with a high degree of internal and external stability, including resistance to twisting and slippage.

A novel absorbent tampon suitable for insertion into a body cavity has a substantially elongate, compressed primary absorbent structure having a first end, a second end disposed opposite thereof, and a density of at least about 0.3 g/cm³. The tampon also includes a secondary absorbent structure secured to and extending from the first end of the primary absorbent structure and extending toward the second end of the primary absorbent structure. Preferably, the secondary absorbent structure is disposed about the primary absorbent structure and forms the outer circumferential surface of the tampon. The secondary absorbent structure is capable of extending outwardly from the primary absorbent structure upon the absorption of fluid into the tampon to increase the cross-sectional area of the tampon in the body cavity. In a preferred embodiment, the tampon has sufficient column strength for digital insertion (insertion without an applicator) into a vaginal canal.

Relatively pain free vaginal dilation is obtained by inserting into the vaginal canal a variable rigidity vaginal dilator having an inflatable balloon, in a manner that avoids insertion into the urethra. Air is introduced into the balloon. When the patient has gained confidence in the pain free use of the dilator, the balloon is deflated to remove the air and water is introduced into the balloon to expand it so that it contacts the vaginal canal and exerts a pressure thereon. This contact is maintained for a period of up to about 15 minutes. The pressure and/or contact time is stepwise sequentially increased to a maximum of about 12 atmospheres and a contact time of up to about 45 minutes, in accordance with a regimen and instructions established by the patient's healthcare provider and tailored to the patient's specific needs. A preferred embodiment of the dilator and a kit employing same, useful in the method of the invention, are disclosed.

The invention provides a devices, methods and systems to measure and record uterine tissue environment components such as pH during the course of uterine artery occlusion. The uterus becomes ischemic due to the occlusion thereof, and its pH drops sharply within minutes of uterine artery occlusion and remains relatively low for a period of time. The return of normal pH is an indicator of return of blood to the ischemic tissue. In use, a catheter with a pH measuring tip is advanced through the patient's vaginal canal and into the patient's uterine cavity until the pH measuring active electrode on the distal end of the catheter contacts or penetrates the uterine fundus. The active electrode detects the pH and a signal representing pH is transmitted to a pH recording and monitoring device which preferably displays the pH. The signal may be transmitted through a conductor or by a radio transmitter. Components other than pH may be monitored such a pCO₂, and pO₂.

A splinting appliance for use in repair of the vaginal wall or uterus includes a body portion, securing means and coupling means. The body portion is shaped to support a substantially normal vaginal apex. The securing means is configured to enable removable securing of the splinting appliance within the vaginal canal. The coupling means enables the splinting appliance to releasably couple with a vaginal elevator device when inserted in the vaginal canal during surgery. Use of the vaginal elevator device when coupled with the splinting appliance aids in location of the vaginal apex. The splinting appliance provides a substantially rigid support which, when in use, facilitates manipulation of tissue at the vaginal wall when approaching through the abdomen e.g. for dissection and/or attachment of a repair graft.
