Abstract: A wireless lock assembly includes a latch assembly that includes a wireless, electrically operated latching component, and a manually movable latching component. The wireless, electrically operated latching component is movable between activated and inactivated positions. The electrically operated latching component will remain in the activated position for a predetermined period of time, after which it will return to the inactivated position. The lock assembly also includes a handle assembly that is manually movable from a non-enabled position into an enabled position when the electrically operated latching component is moved to its activated position. When the handle assembly is in its enabled position, it can be manually moved so as to move the manually movable latching component from a locking condition to a releasing condition. The handle assembly can be manually moved from its non-enabled position to its enabled position by manual engagement and depression of an exposed surface portion thereof.

Abstract: Implantable vascular devices and implantable cardiovascular devices suitable for contacting a patient's blood or bodily fluids include a polymer substrate that is at least partly coated with a diamond-like carbon coating. The diamond-like carbon coated polymer substrate can be flexible or rigid. Preferred medical devices include heart valve prostheses with leaflets or orifice rings formed from diamond-like carbon coated polymer materials. Preferred approaches for the deposition of the diamond-like carbon coating are performed at low pressures and include ion beam assisted deposition.

Abstract: A rotary cutter including a handle, a cylindrical head formed on one end of the handle and having a planar surface on each side, the handle and head having an internal cavity, a unitary actuating member mounted in the cavity in the handle and head, a circular blade supported by the actuating member for movement between a storage position and an operating position with respect to one of the planar surfaces, the actuating member including a spring for biasing the blade to the storage position, and a resilient latch for locking the actuating member in the operative position.
