Abstract

When a patient is fitted with an external gastrostomy connection to the stomach, ingested food can be removed through the gastrostomy connection using a pump-based or siphon-based system to achieve weight loss. The process of removing ingested food can be improved by alternating the infusion of liquid into the stomach with the removal of material from the stomach. Optionally, stomach acid may be captured and returned to the stomach. Optionally, nutritional supplements or medicines may be added to the infused liquid. Optionally, a flush mount connectorized system with a built in valve may be used to simplify the interface with the gastrostomy hardware that remains installed in the patient. Optionally, the system may be configured to disable itself from further use after a triggering event (e.g., the passage of time or a predetermined number of uses) has occurred.

Claims

1-44. -44. (canceled)

45. A valve assembly for alternately providing and preventing the passage of fluid and food through a fluid pathway comprising:

a bottom platform having a first thru-hole biased to one quadrant that passes therethrough;

a top platform having a second thru-hole biased to one quadrant that passes therethrough;

a middle layer having a third thru-hole biased to one quadrant that passes therethrough, the middle layer comprising an elastomeric material and being sandwiched between the bottom platform and the top platform; and

a retainer configured to retain the bottom platform in proximity to the middle layer and top platform such that the middle layer and top platform can be moved together with respect to the bottom platform between a first position and a second position, wherein in the first position the first, second, and third thru-holes align to provide access to the fluid pathway and in the second position the first, second and third thru-holes are not aligned to provide a fluid tight seal and to prevent passage of fluid and food through the fluid pathway.

46. The valve assembly according to claim 45, the bottom platform being configured to sit against a patient'"'"'s skin.

47. The valve assembly according to claim 45, the first, second and third thru-holes each having a diameter from about 6 to about 8 mm.

48. The valve assembly according to claim 45, each platform having a diameter from about 3.5 to about 7 times larger than diameter of the thru-hole that passes therethrough.

49. The valve assembly according to claim 45, the middle layer being sandwiched between the top platform and bottom platform with a force that is high enough to prevent leaks and yet low enough to permit movement of the middle layer with respect to the bottom platform.

50. The valve assembly according to claim 45, the middle layer being attached to the top platform.

51. The valve assembly according to claim 45, one platform being capable of moving with respect to the other platform by a rotational force.

52. The valve assembly according to claim 45, one platform being capable of moving in a substantially linear direction with respect to the other platform.

53. The valve assembly according to claim 45, the valve assembly being configured to provide access to the fluid pathway without changing the internal diameter of the fluid pathway.

54. An apparatus comprising:

a valve assembly for alternately providing and preventing the passage of fluid and food through a fluid pathway comprising;

a bottom platform having a first thru-hole biased to one quadrant that passes therethrough;

a top platform having a second thru-hole biased to one quadrant that passes therethrough,

a middle layer having a third thru-hole biased to one quadrant that passes therethrough, the middle layer comprising an elastomeric material and being sandwiched between the bottom platform and the top platform; and

a retainer configured to retain the bottom platform in proximity to the middle layer and top platform such that the middle layer and top platform can be moved together with respect to the bottom platform between a first position and a second position, wherein in the first position the first, second, and third thru-holes align to provide access to a fluid pathway and in the second position the first, second and third thru-holes are not aligned to provide a fluid tight seal and to prevent passage of fluid and food through the fluid pathway; and

a gastrostomy tube having a distal end and a proximal end;

the first thru-hole of the valve assembly being mated with the proximal end of the gastrostomy tube.

55. The apparatus according to claim 54, the fluid pathway comprising a uniformly sized lumen extending from a gastrostomy tube through the valve assembly.

56. The apparatus according to claim 55, the lumen having a sufficiently large diameter to accommodate food particles.

57. An apparatus for providing and preventing access to a fluid pathway of a gastrostomy tube that passes through a patient'"'"'s abdominal wall into the patient'"'"'s stomach, the apparatus comprising:

a first connector comprising a valve assembly, the valve assembly comprising;

a first platform having a first thru-hole biased to one quadrant that passes therethrough, the first platform being mounted to a gastrostomy tube so as to remain stationary with respect to the gastrostomy tube and so that a fluid pathway is established between the fluid pathway of the gastrostomy tube and the first thru-hole,

a second platform having a second thru-hole biased to one quadrant that passes therethrough,

a third platform having a third thru-hole biased to one quadrant that passes therethrough, the third platform being sandwiched between the first and second platforms and being fixed with respect to the second platform such that the third thru-hole is aligned with the second thru-hole, and

a retainer that retains the first platform in proximity to the second platform such that the second platform can be rotated with respect to the first platform between a first position wherein the first and second thru-holes align to provide access to the fluid pathway of the gastrostomy tube and a second position wherein the first and second thru-holes offset to prevent access to the fluid pathway of the gastrostomy tube,

the connector being configured for flush mounting on a patient'"'"'s skin and having a low profile with respect to the patient'"'"'s skin.

58. The apparatus of claim 57, the first connector further comprising a skin flange, the skin flange being capable of interfacing with the first platform, sitting flush against a patient'"'"'s skin and being connected to a gastrostomy tube positioned in a patient.

59. The apparatus of claim 58 further comprising one or more protrusions disposed on the first platform that fasten to one or more complementary recesses in the skin flange.

60. The apparatus of claim 57 further comprising:

a second connector having a disk defining a disk thru-hole sized and positioned to complement the first and second thru-hole and one or more protrusions that removably couple to one or more structures disposed on the first connector.

61. The apparatus of claim 60 where the second connector further comprises a ridge configured to mate with a valley on the first connector.

62. The apparatus of claim 60 wherein the second connector further comprises a tube having a second fluid pathway that couples to the disk thru-hole.

65. The apparatus of claim 60 wherein the first and second thru-holes are offset in the second position to prevent access to the fluid pathway when the second connector is separate from the first connector.

66. The apparatus of claim 57 wherein aligning the first and second thru-holes in the first position avoids restriction of the gastrostomy tube.

67. The apparatus of claim 57 wherein the first platform further comprises a spout surrounding at least a portion of the first thru-hole, the spout being sized to enter the lumen at the proximal end of the gastrostomy tube.
