Capsule for use in small intestine
First Claim
1. Apparatus, comprising:
- an introducer tube, configured to be advanced into a gastrointestinal tract of a subject;
a guide member coupled to a distal end of the introducer tube said guide member being configured to be inflated and, by inflation thereof, to be mounted within a valve of the subject and to form a pressure seal therewith;
a capsule removably coupled to a distal portion of the introducer tube, said capsule comprising an inflation device configured to form a pressure seal with a wall of the small intestine;
a gas supply configured to propel the capsule distally through the small intestine by generating positive gas pressure proximal to the capsule, such that when said capsule is decoupled from the introducer tube;
said capsule is propelled through a small intestine of the subject; and
a vent tube configured to be advanced from a site that is distal to the capsule to a site that is less distal in the capsule, and to facilitate passage of a fluid from a site distal to the capsule to a site outside the body of the subject;
the capsule being configured to be advanced distally from a pyloric valve of the subject,and wherein the vent tube is configured to be advanced through a colon of the subject.

Abstract
Apparatus for use in a body lumen is provided including an introducer tube configured to be advanced into a gastrointestinal tract of a subject. A guide member is coupled to a distal end of the introducer tube and is configured to be mounted in a vicinity of a valve of the subject. The apparatus also includes a capsule removably coupled to a distal portion of the introducer tube, and configured to be decoupled from the introducer tube and propelled through a small intestine of the subject once the guide member has been mounted in the vicinity of the valve. The apparatus also includes a gas supply configured to propel the capsule distally through the small intestine by generating positive gas pressure proximal to the capsule. Other embodiments are also described.
