Abstract: Left atrial auricle occluder designed to be implanted into a left atrium through a transcatheter route includes a self-expandable hyperelastic cage configured to rest against an inner surface of the left atrium and is provided with an end obturator suitable to be retained frontally against a rim of an auricle, plugging it, by an elastic thrust exerted by the cage.

Abstract: A torque-controlled screwdriver for medical use includes a hollow maneuvering body, coaxially housed within which are a first bushing and a second bushing provided with respective front toothings for mutual torsional coupling. The first bushing is permanently connected in rotation to the maneuvering body, and the second bushing drives a tool in rotation. The front toothings are configured for disengaging from one another when the screwing torque applied by the maneuvering body to the tool exceeds a predetermined threshold value. A system for enabling a free rotation of a pre-set angular amplitude of the maneuvering body with respect to the tool in the opposite direction to that of screwing is located between the second bushing and the tool.
