The present invention relates to the application of medical devices that manage urinary incontinence. The inter-bladder/urethra implanted device allows for passive urine leakage above a threshold bladder pressure and subject-controlled opening and closing of a valve to allow urine passage, below the threshold bladder pressure. The valve is preferably a deformable sac which seals against the interior of the urethra when closed. The valve can be opened by withdrawing slightly from the urethra surface. Passive urine leakage to prevent over-pressure can be facilitated by including external channels on the valve sac. In another embodiment, the valve sac has a central passage which expands and contracts for opening and closing, respectively.

The inventions relates to a transurethral catheter device for bleeding control in pelvic fractures. The catheter device comprises an expandable body assembly with at least one expandable body. The expandable body assembly comprises a proximal portion, a center portion and a distal portion. The expandable body assembly is configured to be expanded from a collapsed state to an expanded state by expanding the at least one expandable body. The expandable body assembly is further configured to be inserted into the urinary bladder of a patient via the urethra in the collapsed state. In the expanded state, the proximal portion has a length l.sub.1 and a width w.sub.1, the center portion a length l.sub.2 and a width w.sub.2, the distal portion a length l.sub.3 and a width w.sub.3, and the expandable body assembly a total length l. A displacement volume V of the expandable body assembly in the expanded state is larger than 0.5 liters. The width w.sub.2 is smaller than 50% of the width w.sub.3. The width w.sub.1 is larger than a width {tilde over (w)}.sub.1 of the proximal portion in the collapsed state and the width w.sub.3 is larger than a width {tilde over (w)}.sub.3 of the distal portion in the collapsed state. The length l.sub.1 is smaller than 25% of the total length l. This allows for arranging the expandable body assembly in the expanded state in the urinary bladder such that the proximal portion is adjacent to the internal urethral orifice of the urinary bladder and the center portion is adjacent to the ureter orifices of the urinary bladder, but not in contact with the ureter orifices.

Everting balloon systems and methods for using the same are disclosed herein. The systems can be configured to access and dilate body lumen and cavities. For example, the systems can be used to dilate the cervix and access the uterine cavity. The systems can also be used to occlude the cervix. The systems can also be used to occlude the urethra.

The invention provides a device for treating urinary incontinence having a fillable expandable balloon made of a flexible material. The wall of the balloon has at least one recess and a valve. A central core located in the lumen of the balloon encloses a central channel having one or more openings and one or more magnetable elements there being.

An implantable device includes a conduit, an adjustable membrane element coupled to the conduit near the front end of the conduit for controllable coaptation of a body lumen, such as coaptation of a urethra as treatment for urinary incontinence, and a fixation mechanism at or near the front end of the conduit. In various embodiments, the fixation mechanism can anchor the implantable device to the tissue using a movement of a push wire. Optionally, the fixation mechanism can also allow the implantable device to be released from the tissue using another movement of the push wire, to allow for re-positioning or removal of the implantable device.

The invention relates to devices (1) for draining or closing a natural or artificial bladder outlet by means of a balloon body (3) made of preferably micro-scale thin-walled Polyurethane, which has a vesical anchor, is transurethrally sealing and is extended into the urethra or through the urethra. According to the invention, the balloon body is seated on a shaft body (2) supporting the balloon, and the filling of the balloon body is preferably done with air.

A device for introducing an implant (1) into blood vessels or hollow organs of the human or animal body. The device includes an implant (1), an insertion wire (14) and a release tube (13), wherein the implant (1) is deformable so that it fits into a microcatheter (8) and expands once the external constraint of the microcatheter (8) disappears, adapting to the diameter of the blood vessel or hollow organ, wherein a holding element (2) is arranged on the insertion wire (14) and the holding element (2) has at its periphery at least one groove (3) set into the holding element (2), running along the circumference of the holding element (2) and forming tracks in the form of curved lines, wherein the implant (1) has holding wired (5) extending proximally, which are fitted into the grooves (3).
