One aspect of the present disclosure relates to a therapy delivery device for treating an obstetric or gynecological disorder other than urinary incontinence in a subject. The therapy delivery device can include a housing, at least one electrode, and a power source. The housing can be configured for implantation in a reproductive system of the subject. The at least one electrode can be connected to the housing and be configured to deliver an electrical signal to an autonomic nervous system nerve target. The power source can be in electrical communication with the at least one electrode.

There is provided a method for controlling a flow of fluid in the vas deferens in order to obtain a controlled male contraception. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the flow vas deferens, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the flow in the vas deferens. The method can be used for restricting or stopping the flow in the vas deferens, or for actively moving the fluid in the vas deferens, with a low risk of injuring the organ.

Apparatus and methods are described including a mechanical support element that is placed inside a first vein of a subject. At least one electrode disposed on the mechanical support element is placed inside the first vein, in a vicinity of a site upstream of a bifurcation with a second vein of the subject. A control unit enhances downstream blood flow from the first vein by driving the at least one electrode to divert blood downstream into the second vein by constricting the first vein at the upstream site, by driving the at least one electrode to apply a current to the vicinity of the site. The mechanical support element prevents the first vein from collapsing by providing mechanical support to the vein. Other embodiments are also described.

A submucosa treating apparatus according to an exemplary embodiment of the present invention includes: a probe that is capable of approaching mucosa of a treatment field; an electrode that is provided in the probe, and applies an electrical signal to blood vessels of submucosa; and a guide where the probe is movably accommodated, and a guide where the probe is movably accommodated, and guiding a position of the electrode with respect to the mucosa.

In a system for electrical stimulation of nerves of a living being a pulse generator is configured to provide a sequence of electrical and/or vibration pulses to at least one electrode and/or vibration generator that are maintained in close proximity to the nerve of interest with the use of means for securing the electrode to the skin or tissue of the living being.

Systems and methods for applying stimulating current to a patient for treating insufficient uterine contractions are provided. The system includes stimulation electrodes of a balloon electrode array device, a ring electrode array device, an electrode probe device, or a mesh electrode array device. Some aspects of the invention also provide a connector and cable device for coupling the stimulation electrodes to electronics for generating and providing the stimulating current to the stimulation electrodes.

A method for identifying a ureter during a medical procedure, the method comprising: providing an electrical stimulator comprising: a shaft having at least one electrode; and a power supply connected to the at least one electrode for providing an electrical signal to the at least one electrode; advancing the shaft so that the at least one electrode contacts tissue; operating the power supply so that the electrical signal is applied to the tissue; and visually observing the tissue to determine the presence of a ureter in the tissue.
