The invention provides a transcutaneous energy transfer device having an external primary coil and an implanted secondary coil inductively coupled to the primary coil, electronic components subcutaneously mounted within the secondary coil and a mechanism which reduces inductive heating of such components by the magnetic field of the secondary coil. For one embodiment of the invention, the mechanism for reducing inductive heating includes a cage formed of a high magnetic permeability material in which the electronic components are mounted, which cage guides the flux around the components to prevent heating thereof. For an alternative embodiment of the invention, a secondary coil has an outer winding and either a counter-wound inner winding or an inner winding in the magnetic field of the outer winding. For either arrangement of the inner coil, the inner coil generates a magnetic field substantially canceling the magnetic field of the outer coil in the area in which the electronic components are mounted.

A removable grip for an ultrasound probe. The grip may be an integrated or unitary hand-held device having a circular or C-shaped cross-section that, when located at a predetermined operative position on the probe, removably surrounds a substantial portion of the probe to provide an exterior shape and size optimal for a desired application. The probe is generally an elongated instrument having proximal and distal ends and an external casing that is grasped by a sonographer. An ultrasound transducer is generally disposed at the distal end and a cord for transferring data and power typically extends from the proximal end of the probe. The grip includes proximal and distal ends and, in one disclosed aspect, a channel for receiving the cord. The channel is defined by opposing edges of the grip that longitudinally extend between the proximal and distal ends. The channel extends through the grip from an exterior surface to an interior surface of the grip. The grip has an attachment feature that enables the grip to be detachably secured to the probe casing when in the operative position such that manual forces applied to the grip to position the probe against a patient do not cause the grip to detach from the probe.
