Abstract
An ingestible device includes a cylindrical capsule having a central axis defined therethrough, a proximal end portion, and an atraumatically shaped distal end portion. A propulsion unit is disposed at the proximal end portion of the capsule for effecting movement of the capsule within an in vivo environment.
Claims17
An ingestible device, comprising:
- a cylindrical capsule having a central axis defined therethrough, the capsule including a proximal end portion and an atraumatically shaped distal end portion;
- and
- a propulsion unit disposed at the proximal end portion of the capsule for effecting movement of the capsule within an in vivo environment, the propulsion unit including:
- a first pair of rotors disposed radially opposite from each other relative to the central axis;
- and
- a second pair of rotors disposed radially opposite from each other relative to the central axis, the second pair of rotors disposed proximal to the first pair of rotors along the central axis, wherein the first pair of rotors is offset from the central axis by a first pitch angle and the second pair of rotors is offset from the central axis by a second pitch angle different than the first pitch angle,
- wherein each rotor of the first and second pairs of rotors is configured to draw fluid through a corresponding inlet formed in the capsule and discharge the fluid through a corresponding outlet nozzle formed in the capsule to propel the capsule.
