TOOLS FOR USE IN SMALL INTESTINE
First Claim
1. Apparatus for use with a biologically-compatible-fluid pressure source, comprising:
- an inflatable guide member, configured to be mounted in a vicinity of a valve of a subject selected from the group consisting of;
an ileocecal valve and a pyloric valve, and to form a pressure seal upon inflation;
an elongate carrier, configured to be slidably advanced through the guide member into a small intestine of the subject; and
an imaging capsule coupled to a distal portion of the carrier, the imaging capsule comprising;
an imaging element; and
a piston head, configured to;
form a pressure seal with a wall of the small intestine, andbe advanced distally through the small intestine in response to pressure from the fluid pressure source.

Abstract
Apparatus (10) is provided for use with a biologically-compatible-fluid pressure source. The apparatus includes an inflatable guide member (30), configured to be mounted in a vicinity of a small intestinal site, and to form a pressure seal upon inflation. An elongate carrier (24) is configured to be slidably advanced through the guide member into a small intestine (20) of the subject. An imaging capsule (26) is coupled to a distal portion of the carrier. The imaging capsule includes an imaging element (42) and a piston head (40). The piston head forms a pressure seal with a wall of the small intestine and is advanced distally through the small intestine in response to pressure from the fluid pressure source.

16. A method for use with a biologically-compatible-fluid pressure source, comprising:
-
forming a pressure seal at a pressure seal site in a vicinity of a valve of a subject selected from the group consisting of;
an ileocecal valve and a pyloric valve;placing an elongate carrier distal to the pressure seal site, in a small intestine of the subject; forming a pressure seal between a piston head coupled to the elongate carrier and a wall of the small intestine; advancing the elongate carrier distally through the small intestine by applying pressure from the fluid pressure source to the piston head; and imaging the small intestine from a distal portion of the carrier. - View Dependent Claims (17, 18, 19, 20, 21, 23, 24, 25, 26, 27, 28, 29)

22. A method for use with a biologically-compatible-fluid pressure source, comprising:
-
forming a pressure seal at a pressure seal site within a small intestine of a subject; placing an elongate carrier distal to the pressure seal site, in the small intestine of the subject; forming a pressure seal between a piston head coupled to the elongate carrier and a wall of the small intestine; advancing the elongate carrier distally through the small intestine by applying pressure from the fluid pressure source to the piston head; and imaging the small intestine from a distal portion of the carrier.
