A medical device has an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ in such a way that said contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with the contractile element not constricting the hollow body organ. The medical device further includes a tensioning device adapted to apply a force so as to tighten the contractile element around the hollow body organ. The contractile element further includes a closure for forming the contractile element into a closed loop around said hollow body organ, the closure having a plurality of lips arranged to engage the contractile element.

Medical device comprising an artificial contractile structure

A medical device including an artificial contractile structure which may be advantageously used to assist the functioning of a hollow organ. Specifically, the medical device includes an artificial contractile structure with at least one contractile element adapted to contract an organ, in such way that the contractile element is in a resting or in an activated position, at least one actuator designed to activate the contractile structure, and at least one source of energy for powering the actuator. The medical device also includes a means for reducing corrosion of the medical device hence reducing the risk of the device dysfunction and patient contamination.

Medical device including an artificial contractile structure including at least one contractile element adapted to contract a hollow body organ, in such a way that the contractile element is adapted to be in a resting position or in an activated position, the activated position being defined with the contractile element constricting the hollow body organ and the resting position being defined with said contractile element not constricting the hollow body organ. The medical device can include a tensioning device adapted to apply a force so as to tighten the contractile element around said hollow body organ. The tensioning device can be arranged to cause the contractile element to apply a substantially uniform occlusive pressure of at most 8N/cm, along the circumference of the contact area between the contractile element and the hollow body organ when the contractile element is in its activated position.

A medical device including an artificial contractile structure, which may be advantageously used to assist the functioning of a hollow organ, is provided.

Abutment with a hydroxylated surface

A method for manufacturing a one-piece dental implant. The method includes the steps, in any order, of manufacturing an outer body of metal having a cavity and manufacturing an inner body of plastic or composite material having an outer profile. The cavity has an inner profile, and the outer profile of the inner body is complementary to the inner profile of the cavity of the outer body. The inner body includes a core manufactured within the cavity of the outer body. The respective profiles are wavelike rounded in an axial direction of the dental implant and tapering from the crestal end of the outer body to the apical end of the outer body, such as to decrease tension between the inner and the outer bodies and/or such that to provide for an anti-rotation lock between the two bodies.
