URETHRAL ARTIFICIAL SPHINCTER WITH BISTABLE ACTUATION SYSTEM

摘要

An artificial sphincter to be implanted in a urethra, in particular, for treating patients suffering from urinary incontinence, comprises a container (10) configured to be connected to a wall of a urethra (4), inside or outside it, a valve unit (20) housed within the container (10) and configured to move from a release configuration (R) to a block configuration (B) and vice-versa; an actuation magnet (66) movably (rotatably or slidably) arranged between a first and a second position in the container (10), and connected to the valve unit (20) in such a way that a predetermined (rotation or translation) movement (67', 67") of the actuation magnet (66) from a first towards a second position, or from the second towards the first position, under the effect of an external manoeuvre magnet (90), brings the valve unit (20) from the release configuration (R) to the block configuration (B), where the valve is stably maintained, and from the block configuration (B) to the release configuration (R), where the valve is stably maintained.
