Abstract

A gastrointestinal system including a carrier including an actuator in operative communication with at least one traction member, the actuator moving the at least one traction member relative to the carrier, wherein the at least one traction member is movably supported across supports extending from the carrier, and wherein a portion of the at least one traction member between the supports is sufficiently compliant so as to deform in conformance with a shape of a gastrointestinal tract during traction therealong.

Claims

1. A gastrointestinal system comprising:

at least one traction member;

a carrier comprising an actuator in operative communication with said at least one traction member, said actuator moving said at least one traction member relative to said carrier, wherein a portion of said at least one traction member is sufficiently compliant so as to deform in conformance with a shape of a gastrointestinal tract during traction therealong; and

a pulley system,

wherein said at least one traction member is arranged for rotation about said pulley system, and

wherein said pulley system comprises;

pulley wheels;

a belt placed around said pulley wheels; and

spacers, which space said at least one traction member from and connect said at least one traction member to said belt.

2. The gastrointestinal system according to claim 1, wherein said at least one traction member is more compliant than said belt.

3. A gastrointestinal system comprising:

at least one traction member;

a carrier comprising an actuator in operative communication with said at least one traction member, said actuator moving said at least one traction member relative to said carrier, wherein a portion of said at least one traction member is sufficiently compliant so as to deform in conformance with a shape of a gastrointestinal tract during traction therealong,

wherein said at least one traction member comprises;

an arm;

a roller, mounted for rotation on said arm and operatively connected to said actuator; and

an elastomeric member applied over said roller.

4. The gastrointestinal system according to claim 3, wherein said elastomeric member is stretched over said roller.

5. The gastrointestinal system according to claim 3, wherein said elastomeric member is coated on said roller.

6. The gastrointestinal system according to claim 3, wherein an outer surface of said roller is shaped so as to define a plurality of indentations separated by walls.

7. The gastrointestinal system according to claim 3, wherein said roller is shaped so as to define a fluid passage arranged for fluid communication with at least one port formed in said arm, said port being adapted to be connected to at least one source selected from the group consisting of:

a suction source and a blowing source.
