Medical apparatus includes an external drive magnet mounted for rotation externally of a subject's body, an implantable driven magnet configured and dimensioned to be implantable in the subject's body and mounted for rotation by magnetic coupling with the drive magnet and an implantable device mechanically coupled to the driven magnet to be driven thereby. The driven magnet is mountable for rotation in the subject's body about an axis of rotation which is not collinear with the axis of rotation of the external drive magnet such that the magnetic poles of the external drive magnet are magnetically coupled sequentially with the magnetic poles of the implanted driven magnet to rotate the implanted driven magnet, thereby providing flexibility in the location, design and dimensions of the implanted driven magnet, and in the speed and torque ratios between the two magnets.

[ I claim:] [35.] A medical apparatus, comprising:a drive magnet, externally located with respect to a subject's body, having a first axis, and mounted on a first support means for supporting said drive magnet along said first axis for rotation about said first axis; and,a fluid pump dimensioned to be contained in a fluid carrying vessel of the subject's body, said pump comprising a housing containing a driven magnet, an inlet and an outlet, said driven magnet having a second axis and being mounted on a second support means for supporting rotation of said driven magnet about said second axis by magnetic pole coupling with said drive magnet when said driven magnet is implanted in the subject's body and said drive magnet is rotated sufficiently close to said driven magnet to be magnetically coupled thereto.
