Abstract

A device for treating obesity in humans is described, with a balloon arrangement that can be introduced into the human stomach and that can be filled with a fluid and emptied inside the stomach for controlled reduction of the stomach volume; with at least one fluid line, which is connected in a fluid tight manner to the balloon arrangement and via which the balloon arrangement can be filled and emptied transcutaneously; with at least one securing means provided along the fluid line in order to fix the fluid line to skin and tissue layers enclosing the stomach; and with at least one valve unit provided along the fluid line. The balloon arrangement has a first means that can be filled with the fluid and assumes a balloon-like configuration in a filled state, a second fillable means which, in a filled state, assumes a ring-shaped or loop-shaped configuration and radially encloses a clear internal diameter, and the first and second means are connected to each other in so that the first means extends into a first half space via a plane enclosed by the ring-shaped or loop-shaped configuration of the filled second means.

35. A device according to one of claim 29, wherein:

the first and/or second means has on a side, which faces radially away from a clear internal diameter, a holding element which clamps an area and is used for bearing against an inner wall region of the stomach.

36. A device according to one of claim 30, wherein:

the first and/or second means has on a side, which faces radially away from a clear internal diameter, a holding element which clamps an area and is used for bearing against an inner wall region of the stomach.

37. A device according to one of claim 31, wherein:

the first and/or second means has on a side, which faces radially away from a clear internal diameter, a holding element which clamps an area and is used for bearing against an inner wall region of the stomach.

38. A device according to claim 32, wherein:

the holding element is plate-shaped, ring-shaped or star-shaped.

39. A device according to claim 33, wherein:

the holding element is plate-shaped, ring-shaped or star-shaped.

40. A device according to claim 37, wherein:

the holding element is plate-shaped, ring-shaped or star-shaped.

41. A device according to claim 32, wherein:

the at least one fluid line is connected to the first and/or second means in the region of the holding element.

42. A device according to claim 38, wherein:

the at least one fluid line is connected to the first and/or second means in the region of the holding element.

43. A device according to claim 26, wherein:

44. A device according to claim 38, wherein:

a fixing element is disposed along the fluid line proximally at a distance from the holding element.

45. A device according to claim 41, wherein:

a fixing element is disposed along the fluid line proximally at a distance from the holding element.

46. A device according to claim 43, wherein
