Abstract

Abstract Implantable training appliance for a muscle, which is present for supporting the heart muscle, having a first chamber (3) which is filled with a gaseous and/or a liquid medium, has elastically deformable walls (4), and is surrounded by the muscle to be trained, and is connected to a second chamber (10, 11) which is connected to the first chamber and can exert a counterpressure on a medium flowing into the second chamber (10, 11). Through the periodic stimulation of the muscle surrounding the first chamber (3), to and fro flow of the medium between the two chambers is achieved by repeatedly compressing the first chamber (3). After sufficient muscle training the chambers are removed and the remaining hollow muscle is connected to the circulation system as a heart-supporting pump.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 148 words
Training appliance for a muscle to replace the heart muscle function for internal use, comprising a first chamber (3, 23) to be filled with a fluid and to be surrounded by said muscle said first chamber having elastically deformable outer walls (4, 24), while the first chamber (3) can be deformed between a first state in which the chamber takes up a maximum volume and a second state in which the chamber has a smaller volume than in the first state, and a second chamber (10, 11, 30) immediately adjacent to said first chamber and in fluid communication with the first chamber, said second chamber having displacable walls for allowing increasing the volume of the second chamber when the first chamber is in the second state, one of said first and second chambers having introduction means (17) for fluid, one of said chambers having pressure observation means (19).
Claim 2
Dependent Claim 148 words
Training appliance for a muscle to replace the heart muscle function for internal use, comprising a first chamber (3, 23) to be filled with a fluid and to be surrounded by said muscle said first chamber having elastically deformable outer walls (4, 24), while the first chamber (3) can be deformed between a first state in which the chamber takes up a maximum volume and a second state in which the chamber has a smaller volume than in the first state, and a second chamber (10, 11, 30) immediately adjacent to said first chamber and in fluid communication with the first chamber, said second chamber having displacable walls for allowing increasing the volume of the second chamber when the first chamber is in the second state, one of said first and second chambers having introduction means (17) for fluid, one of said chambers having pressure observation means (19).
Claim 3
Dependent Claim 48 words
Training appliance according to claim 1, in which said displaceable wall means comprise an elastically deformable wall (38) which in the first state of the first chamber bounds a first volume in the second state of the first chamber defines a second, larger volume of the second chamber.
Claim 4
Dependent Claim 30 words
Training appliance according to claim 1, further comprising a container space which is separated by a deformable wall from the content of the second chamber, which container space is compressible.
Claim 5
Dependent Claim 41 words
Training appliance according to claim 3, in which the second chamber (30) is formed completely inside the first chamber, and the second chamber is provided with a rigid wall (31) which forms the division between the first and the second chamber.
Claim 6
Dependent Claim 22 words
Training appliance according to claim 1, in which the second chamber (10, 11) is formed at one end of the first chamber.
Claim 7
Dependent Claim 23 words
Training appliance according to claim 1, in which the connection (13, 14) between the first and the second chamber comprises a fluid restriction.
Claim 8
Dependent Claim 13 words
Training appliance according to claim 1, in which the fluid is a liquid.
Claim 9
Dependent Claim 157 words
Training appliance for a muscle to replace the heart muscle function for internal use, comprising a first chamber (3, 23) to be filled with a fluid and to be surrounded by said muscle, said first chamber having elastically deformable outer walls (4, 24), while the first chamber (3) can be deformed between a first state in which the chamber takes up a maximum volume and a second state in which the chamber has a smaller volume than in the first state, said first chamber in said first state being barrel shaped, and two second chambers (10, 11, 30) immediately adjacent to and at opposite ends of said first chamber and in fluid communication with the first chamber, which second chambers having displaceable walls for allowing increasing the volume of said second chambers when the first chamber is in the second state, wherein one of said first and second chambers is provided with introduction means (17) for fluid.
Claim 10
Dependent Claim 157 words
Training appliance for a muscle to replace the heart muscle function for internal use, comprising a first chamber (3, 23) to be filled with a fluid and to be surrounded by said muscle, said first chamber having elastically deformable outer walls (4, 24), while the first chamber (3) can be deformed between a first state in which the chamber takes up a maximum volume and a second state in which the chamber has a smaller volume than in the first state, said first chamber in said first state being barrel shaped, and two second chambers (10, 11, 30) immediately adjacent to and at opposite ends of said first chamber and in fluid communication with the first chamber, which second chambers having displaceable walls for allowing increasing the volume of said second chambers when the first chamber is in the second state, wherein one of said first and second chambers is provided with introduction means (17) for fluid.
