According to the invention, an uterotubal implant device is provided. Said uterotubal implant device comprises at least two compressible self-expanding bodies which are composed of a grid structure and are coupled to one another in a longitudinal direction such that one body is arranged distally in the longitudinal direction and the other body is arranged proximally in the longitudinal direction, at least one of the bodies having a spindle- or funnel-shaped design.

The disclosure relates to a vas deferens valve for contraception for use in a man and for implanting in the vas deferens within the scrotum, enabling the regulating of sperm flow in the vas deferens. There is a manually activated rocker switch which can be activated through the skin of the scrotum and which has a through-channel which, in the opened state, leads from a valve connection piece on the testicular vas deferens to a valve connection piece on the abdominal end of the vas deferens and, in the closed valve state, can be blocked on the end of the through-flow channel which faces the abdominal vas deferens end. The valve additionally has at least one outlet channel which, in the closed state of the valve, leads from the valve connection piece on the testicular end of the vas deferens out of the valve to the outside in the body of the man.

An apparatus which includes a closure member and delivery systems for closing vessels in the body of a patient is disclosed. In one embodiment, the closure member is a hemostatic closure member having a cylindrical shape and an expandable volume on contact with fluids. The hemostatic member includes a functional passageway through the length of the member so that it may be mounted over a delivery catheter or wire guide for delivery against a vessel puncture or into another vacuslar environment, such as to fill an aneurysm sac. In another embodiment the closure member is a fallopian tube closure member which is deployed into the fallopian tube over a guide wire to prevent conception. The fallopian tube member includes a loop-shaped frame having barbs, a first layer of material, a binding wire, a second layer of material, and an expandable volume on contact with fluids.

The present invention introduces a groundbreaking solution in the field of male contraceptiona reversible male birth control implant device. The device offers enhanced flexibility in family planning by controlling the amount of sperm ejaculated. It consists of a tubular component surgically inserted into each severed vas deferens, with a wireless receiver attached. The wireless receiver receives external wireless signals and enables the device to switch between a state that permits the flow of sperm and a state that impedes it. The device also features an outlet for the safe elimination of obstructed sperm. The use of biocompatible materials and compatibility with medical imaging devices, such as MRI, ensures safety and usability. This innovative device empowers individuals with convenient and discreet control over their fertility, revolutionizing male contraception and opening new possibilities in reproductive health.

Contraceptive devices that provide substantially immediate and permanent sterilization are described herein. Systems and methods for transcervically delivering the contraceptive devices are also described herein. The contraceptive device may include an expandable implant. The implant includes hydrogel to provide substantially immediate sterilization, and tissue in-growth fibers to provide permanent sterilization. As an alternative or in combination to hydrogel, the implant may include copper or cupric ions to provide substantially immediate sterilization. The implant may also include hydrogel to improve trackability of the implant through an ovarian pathway.
