Abstract
Methods and devices for actuating a clearance device to clear obstructive debris from medical tubes are disclosed. More particularly, a shuttle that includes a first primary magnetic element that is adapted to magnetically engage and translate a magnetic guide within a tube is disclosed. The first primary magnetic element is aligned so that a first primary magnetic field emanating therefrom is aligned substantially perpendicular to a longitudinal axis of the tube when viewed from a side of the shuttle.
Claims18
A device for clearing obstructions, comprising:
- a tube defining a passageway;
- a guide member disposed within said passageway and configured to translate axially therein;
- a shuttle disposed outside of said passageway, said shuttle being coupled to said guide member such that translation of said guide member depends on a movement of the shuttle;
- a first magnet disposed on the shuttle and emitting a first magnetic field having a first magnetic-field axis;
- and
- a second magnet disposed on the shuttle and emitting a second magnetic field having a second magnetic-field axis, said first magnet opposing said second magnet with respect to the tube such that said first and second magnetic-field axes are aligned along a common radial axis relative to said tube.
