Magnetically-coupled implantable medical devices
First Claim
1. A medical apparatus, comprising:
- a drive magnet, externally located with respect to a subject'"'"'s body, having a first axis and mounted for rotation about said first axis;
a driven magnet having a second axis and configured and dimensioned to be implantable in the subject'"'"'s body and mounted for rotation about said second axis by sequential magnetic pole coupling with said drive magnet when said driven magnet is implanted in the subject'"'"'s body and the drive magnet is rotated sufficiently close to the driven magnet to be magnetically coupled thereto;
wherein said first and said second axis are parallel;
and an implant device implantable in the subject'"'"'s body coupled to said driven magnet to be operated by rotation of said driven magnet.

Abstract
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 t 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.
