Abstract

A device for modifying an eating behavior of a subject is provided. The device includes a device body which is attachable to GI tract tissue of a subject and functions in altering an eating behavior thereof.

Claims

1-34. -34. (canceled)

35. A device for modifying an eating behavior of a subject comprising a device body attachable to tissue of a stomach, said device body being sized and configured for passing through a pyloric opening when detached from said tissue of said stomach.

36. The device of claim 35, wherein said device body is attached to said stomach tissue via a tether.

37. The device of claim 36, wherein a first end of said tether is designed for anchoring in or through said tissue of said stomach.

38. The device of claim 35, wherein at least a portion of the device body is hollow.

39. The device of claim 35 wherein said device body has a volume of 4 cm³ or less.

40. The device of claim 35 wherein said device body has a surface area 15 cm² or less.

41. The device of claim 36, wherein at least a portion of said tether can reversibly increase in length by least 25%.

42. The device of claim 36, wherein at least a portion of said device body is capable of moving between a stomach and a duodenum when attached to said tissue of said stomach.

43. The device of claim 35, wherein said device body has a maximum diameter of 2 cm.

44. The device of claim 36, wherein said tether is 0.5-10 cm in length.

45. The device of claim 35, wherein said device body includes one or more discs.

46. The device of claim 35, wherein the device is configured for at least partially blocking said pylorus from the stomach or duodenal side.

47. The device of claim 35, wherein said device body is capable of moving between an antrum and a duodenum with natural peristaltic and reflux forces.

48. The device of claim 35, wherein said device body consists of one or more polymers.

49. The device of claim 35, wherein said device body is non-expandable.

50. A method of altering eating behavior in a subject comprising attaching a device to a tissue of a stomach of a subject in need, said device having a device body being designed and configured for passing through a pylorus.

51. The method of claim 50 wherein said device is attached to said stomach tissue via a tether.

52. The method of claim 50 wherein said device intermittently and/or partially blocks the pylorus.

53. A method of anchoring a device in the stomach of a subject comprising passing a first end of a tether through a stomach tissue fold wherein a second end of said tether is attached to a device body.

54. The method of claim 53, wherein said first end of said tether passes through a washer.
