There is provided a method for controlling a flow of sperms in a uterine tube of a female patient. The method comprises electrically stimulating a uterine tube wall portion by controlling an implanted stimulation device from at least one of an external control unit and an internal control unit, wherein the electrically stimulating causes contraction of the uterine tube wall portion along a length of the portion to restrict the flow of sperms in the uterine tube.

An apparatus for irrigating the vas deferens in connection with a vasectomy reversal is described. The apparatus comprises a fluid delivery device having a first portion that connects to the vas deferens, the fluid delivery device connecting such that a catheter tip inserts into the vas deferens and is held in stable position relative thereto and such that fluid enters the vas deferens through the catheter tip.

Medical devices and methods for treating and occluding a female patient's fallopian tubes to provide permanent birth control or sterilization.

Medical devices and methods for treating and occluding a female patient's fallopian tubes to provide permanent birth control or sterilization.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may be useful in the treatment of infertility associated with PCOS.

Various features are described that are adapted to improve performance of interference-relief type delivery systems. A delivery system provided herein comprises an implant comprising a socket at a proximal end of the implant; an elongate sleeve having (i) a proximal section, (ii) a distal section slidably disposed within the socket, and (iii) a window between the proximal section and the distal section, the window extending through a wall of the sleeve; and a core member having a proximal portion slidably received within the proximal section of the sleeve and a distal portion extending through the window to a space outside the sleeve and within the socket. The distal portion of the core member provides an interference fit with the distal section of the sleeve within the socket until the core member is withdrawn.

There is provided a method for controlling a flow of eggs in a uterine tube formed by a uterine tube wall of a patient. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the uterine tube wall) at least one portion of the uterine tube wall to influence the flow of eggs in the uterine tube, and stimulating the constricted wall portion to cause contraction of the uterine tube wall portion to further influence the flow of eggs in the uterine tube. The method can be used for restricting or stopping the flow of eggs in the uterine tube, or for actively moving the fluid in the uterine tube, with a low risk of injuring the uterine tube.

The present methods, systems, and devices relate to an occlusion device for blocking a biological tube, the biological tube being prone to a peristaltic wave having a wave length, and where the occlusion device comprises at least two sections, where each section is connected by at least one narrowing to at least one other section. The occlusion device is of an elastic material, and each section is configured to deform when a force is applied by the peristaltic wave, and the length of at least one of the at least two sections corresponds substantially to the wave length of the peristaltic wave in the biological tube, so as to absorb the peristaltic wave. The methods, systems, and devices relates to reversible contraception of female and/or male gendered species intervening with biological tube, which are responsible for transportation of fertility fluids, such as the transportation of spermatozoes or oocytes in for example the human reproductive system.
