Abstract
Disclosed is a magnetic prosthetic suspension system. The system includes a magnetic implant configured to be fixedly attached to bone at a target site of a subject, a socket configured to fit over the target site of the subject, and a magnet positioned on or within the socket, where the magnet is configured to generate a magnetic attractive force between the magnetic implant and the magnet that suspends the socket at the target site of the subject.
Claims33
A magnetic prosthetic suspension system, comprising:
- a magnetic implant configured to be fixedly attached to bone at a target site of a subject;
- a socket configured to fit over the target site of the subject;
- and
- a magnet positioned on or within the socket;
- wherein the magnet is configured to generate a magnetic attractive force between the magnetic implant and the magnet that suspends the socket at the target site of the subject.
A method for magnetic prosthetic suspension, comprising the steps of:
- attaching a magnetic implant to a bone at a target site of a subject;
- positioning a socket comprising a magnet over the target site;
- and
- generating a magnetic attractive force between the magnet and the magnetic implant, thereby suspending the socket from the target site.
A permanent magnet assembly, comprising:
- a first plurality of permanent magnets forming an inner Halbach array cylinder configured to produce a predominantly axial flux;
- a second plurality of permanent magnets forming an outer Halbach array cylinder configured to produce a predominantly axial flux, wherein the inner Halbach array cylinder is nested within the outer Halbach array cylinder such that the inner Halbach array cylinder and the outer Halbach array cylinder are coaxially aligned and a relative rotation between the inner and outer Halbach array cylinders results in an adjustable axial flux.
