1. A medical device comprising:
- a distal end adapted to be inserted into a patient;
a proximal end adapted to interface with an operator;
an elongate body disposed between the proximal and distal ends;
at least one electromagnet disposed on the elongate body wherein said at least one electromagnet is disposed a first distance from the central longitudinal axis of the elongate body;
at least one ferromagnetic or paramagnetic material disposed on or in the elongate body in a position such that the electromagnet applies a force to the ferromagnetic or paramagnetic material when current travels through the electromagnet; and
,wherein the ferromagnetic or paramagnetic material is disposed a second distance from the central longitudinal axis of the elongate body; and
a torque is created between the electromagnet and the material when current is passed through the electromagnet.

Abstract
In one embodiment, an elongate body with a proximal end and a distal end is disclosed and which is controllable by an operator at the proximal end; in one embodiment, the elongate body is a catheter and the catheter tip is located at the distal end. The body contains numerous magnets along its length, at least one of which is an electromagnet, controllable by means of a current delivered by the operator of the body at the proximal end of the body. The magnets are placed such that a force is created at the distal end of the elongate body. The magnetic forces which control the distal end of the body originate from the controllable magnets placed on the body.
