  • Patent number: 9095341
    Abstract: A medical device including artificial contractile structures generally devised to be used in the medical field. Such structures may be advantageously used to assist the functioning of an organ. The medical device includes an artificial contractile structure having at least two contractile elements (100) adapted to contract an organ, in such way that each of the contractile elements (100) can be in a resting or in an activated position, independently of the position of each other, the activated position being defined with the contractile element (100) constricting the organ and the resting position being defined with the contractile element (100) not constricting the organ, and at least one actuator designed to activate the contractile structure. Each contractile element (100) is connected to an adjacent contractile element (100), while remaining flexible one with respect to the other.

  • Patent number: 8439979
    Abstract: An artificial contractile structure generally devised to be used in the medical field to assist the functioning of an organ, includes a support (2) and one or more fibers (5) fixed thereto. The fibers are made of a contractile material which can be activated by an activator so as to provide the structure in a rest or activated position, the activated position being defined with fibers of reduced length compared to their length in the rest position. The structure is adapted to be placed around a hollow part of an organ to be contracted. The fibers are distributed along the support in order to be able to reduce the volume of the hollow part, when the fibers are contracted. The fibers and the activator are designed so that the temperature of fluids or tissues surrounding the organ does not increase above 40° C., preferably 39° C., and more preferably 38° C.
