Copyright 2020 The Authors, An advantage of MNS would be that SCS leads could be placed outside an operating room (similar to a lumbar puncture, which can be done in a physician's office) through a Touhy needle into the epidural space. Here, we describe the challenges of SCS implant surgery and how MNS can be used to overcome these hurdles. However, early results in deep brain stimulation with multiferroics demonstrate a beneficial effect, which is promising for application in the spinal cord (Singer et al., 2020; Kozielski et al., 2021). doi: 10.1088/1361-6528/ac43e6.

These concepts are discussed to describe the interactions between micro/nanorobots and magnetic fields. Sufficient flexibility of the catheter tip is necessary to provide steering freedom and after removal of the magnetic field, stress-relaxation (micro-shattering of the electrode tip) should be avoided (Jonathan and Groen, 2005; Petruska et al., 2016). A variable stiffness catheter design could be a solution to this optimization problem (Figure 2B). 2019 American Chemical Society.
