包括人造收缩性结构的医疗装置
摘要：
本发明设计一种包括人造收缩性结构的医疗装置，该人造收缩性结构有利地用于辅助中空器官的功能。所述医疗装置包括人造收缩性结构，该人造收缩性结构包括：被适于收缩器官的至少一个收缩性元件(100)，以此方式所述收缩性元件(100)处于闲置或被激活位置中；被设计成激活所述收缩性结构的至少一个致动器；以及为所述致动器供能的至少一个能量源。“将该收缩性元件维持在其被激活位置及其闲置位置中所需要的电流与改变该收缩性元件的位置所需要的电流”之比是小于1/500，优选地小于1/800，并且更优选地小于1/1000。所述医疗装置进一步包括用于降低该医疗装置的腐蚀的手段。
摘要（英）：

The present invention relates to a medical device comprising an artificial contractile structure which may be advantageously used to assist the functioning of a hollow organ. Said medical device comprises an artificial contractile structure comprising at least one contractile element (100) adapted to contract an organ, in such way that said contractile element (100) is in a resting or in an activated position, at least one actuator designed to activate said contractile structure, and at least one source of energy for powering said actuator. The ratio "current which is needed to maintain the contractile element in its activated position / current which is needed to change the position of the contractile element" is less than 1/500, preferably less than 1/800, and more preferably less than 1/1000.Said medical device further comprises means for reducing corrosion in the control unit (114).
