Chirurgischer Ring mit Fernsteuerungseinrichtung für reversible Durchmesserveränderungen

The implant consists of a ring of variable diameter. It has a supple lengthwise inner filament, fixed at one end and able to slide relative to the loop. The free end of the filament is connected to an actuator that can tension/release it to reduce/increase the ring's diameter. The filament can...

Beschreibung
Zusammenfassung:	The implant consists of a ring of variable diameter. It has a supple lengthwise inner filament, fixed at one end and able to slide relative to the loop. The free end of the filament is connected to an actuator that can tension/release it to reduce/increase the ring's diameter. The filament can interact with the actuator by a threaded mechanism formed by a nut in the actuator, and the outer spiral surface of a spring surrounding the filament. The implant consists of a ring in the form of a closed loop of variable diameter. It has a supple lengthwise inner filament (4), fixed at one end (5) and able to slide relative to the material of the loop. The free end (7) of the filament is connected to an actuator (8) that can tension or release it to reduce or increase the ring's diameter as required. The filament can interact with the actuator by a threaded mechanism formed by a nut in the actuator, driven by a radio-controlled electric motor, and the outer spiral surface of a spring surrounding the filament.
