Abstract
A magnetically guidable intubation device including performing means for performing a medical procedure. A magnetically guidable member is connected with a device for performing a medical procedure within the body. The magnetically guidable intubation device is effective to be introduced into a patient's body and magnetically guided within the body by an externally applied magnetic field. A flexible retrieving member may be fixedly attached to the magnetically guidable member and is used for retrieving the magnetically guided member from the body. An external magnetic field is applied and is effective to guide the magnetically guidable member within the body to perform the medical procedure. The magnetically guidable member may include a core and a conductive winding wound around the core. A remotely controllable current source may be provided for applying an electric current to the winding which is effective to induce a magnetic field around the magnetically guidable member. Thus, by changing the field strength and polarity of the magnetic field around the magnetically guidable member, precise control of the magnetically guidable member can be realized.
