Gastro-occlusive device
First Claim
1. A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a dermal wall of the patient'"'"'s body or extends exteriorly out of the dermal wall of the patient'"'"'s body, and means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least a portion of the volume of the stomach cavity, wherein the dermal wall and the stomach wall are in spaced relationship to one another, and wherein the gas tube is positionally anchored at both the stomach wall and the dermal wall of the patient.

Abstract
A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending outwardly through a stomach wall for coupling with a gas source for selectively inflating the balloon, to occlude at least a portion of the volume of the stomach cavity. The gastro-occlusive device may be employed in combination with a feeding tube unit, a drain unit or other ancillary apparatus, and is useful for treatment of morbid obesity and various eating disorders.

- 1. A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a dermal wall of the patient'"'"'s body or extends exteriorly out of the dermal wall of the patient'"'"'s body, and means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least a portion of the volume of the stomach cavity, wherein the dermal wall and the stomach wall are in spaced relationship to one another, and wherein the gas tube is positionally anchored at both the stomach wall and the dermal wall of the patient.
- 5. A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a surface of the patient'"'"'s body, and means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least a portion of the volume of the stomach cavity, wherein the proximal end of the gas flow tube is coupled to a subcutaneous sealable membrane and port assembly that is subcutaneously engageable with an injector of inflation gas for inflation of the balloon.
- 26. A method of treating a subject in need of treatment for an eating disorder or overweight condition, said method comprising disposing in the stomach of the subject a balloon that is inflatable to occlude at least a portion of interior volume of the stomach, wherein the balloon is coupled by a gas flow passage to an actuatable source of inflation gas, and actuating the source of inflation gas to flow gas into the balloon for inflation thereof to occlude at least a portion of the interior volume of the stomach, to an extent producing satiety with reduced intake of nutrition, relative to a corresponding subject lacking the inflated balloon in the subject'"'"'s stomach, wherein the stomach is defined by a stomach wall, said gas flow passage is at or in interior proximity to a dermal wall of the subject'"'"'s body or extends exteriorly out of the dermal wall of the subject'"'"'s body, said dermal wall and the stomach wall are in spaced relationship to one another, and said gas flow passage is positionally anchored at both the stomach wall and the dermal wall of the subject.

34. A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that is at or in interior proximity to a surface of the patient'"'"'s body or extends exteriorly out of a dermal wall of the patient'"'"'s body, and means for selectively inflating the balloon, coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least a portion of the volume of the stomach cavity, wherein the gas flow tube is a single lumen tube.

35. A gastro-occlusive device, comprising a balloon disposable in a stomach cavity of a patient, and inflatable therein to occlude a portion of the volume of the stomach cavity, a gas flow tube coupled at a distal end thereof with the balloon and extending through a stomach wall to a proximal end that extends exteriorly out of a dermal wall of the patient'"'"'s body, and means for selectively inflating the balloons coupled to the gas flow tube at the proximal end thereof and arranged to flow inflation gas to the balloon in the patient'"'"'s stomach cavity, for said inflation therein to occlude at least a portion of the volume of the stomach cavity, wherein the gas flow tube extending through the stomach wall is retained in position by a first exterior flange member and a first interior flange member, and wherein the gas flow tube extending through the dermal wall is retained in position by a second exterior flange member and a second interior flange member.
