An implantable device for the treatment of acid reflux disease has a body including an outer surface adapted to rest against a patient's fundus wall. The device, when implanted in a patient, fills a volume in the patient's abdomen in the cardia area and above the cardia of the patient, when standing. The body prevents the cardia from moving through the diaphragm opening into the thorax, thereby preventing reflux by keeping the abdominal pressure supporting the cardia sphincter muscle. The device may be affixed to stomach tissue. The device may also be invaginated or otherwise indirectly secured in position.

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.

The abdominal circulatory pump uses expulsive manoeuvres performed by contraction of the diaphragm while stabilizing, contracting or compressing the abdominal wall to increase abdominal pressure and pump blood. At the same time, it can be used to lower pleural pressure around the surface of the lung to provide ventilation. In humans the blood in the splanchnic circulation; i.e., the blood in the abdominal contents, is a reservoir of about 20% to 25% of the whole body blood volume. The increase in abdominal pressure forces this blood to flow out of the abdomen and through the body.

Even when a urinary incontinence patient exercises, sneezes or coughs to increase the abdominal pressure instantaneously, the device can sufficiently inhibit urinary incontinence. Furthermore, the device does not require a guide needle holder that causes damage, and is minimally invasive so that damage associated with an invasive method can be reduced. Also, the device eliminates the need for spinal anesthesia or sedative anesthesia and does not cause discomfort that can occur when excessive local anesthesia is performed. In addition, it can be easily corrected in a non-invasive manner when the therapeutic effect thereof is insufficient. Furthermore, it is easily removed so that it makes it possible to perform surgery again using other methods when the therapeutic effect thereof is insufficient.
