Utilizing Untethered Magnetic Micro- and Nanorobots for SCS. In current procedures, connective adipose tissue (e.g., fibrous septa in the dorsal epidural space) is often penetrated, and the catheter is guided straight through whenever the composition of the adipose tissue permits. Materials (Basel). Alternatively, a simple variable stiffness catheter design can be based on current technology, where the stiffness of the stimulation lead is controlled by the degree of insertion of the guidewire (Schulder, 2003). A neodymium-iron-boron (NdFeB) permanent tip has been suggested with magnetically guided catheters, as NdFeB has the highest magnetic remanence among commercially available magnets (Gutfleisch et al., 2011; Hong et al., 2021). method.

Here, we describe the challenges of SCS implant surgery and how MNS can be used to overcome these hurdles. Magnetic navigation of tethered probes represents a novel technology that offers potential to improve dexterity control, the option for postoperative readjustment of the electrode to modulate the volume of activated tissue, increases safety, and reduces cost in spinal cord stimulation surgery. Notably, increased operating time is a known risk factor for infection and revision surgeries trend toward longer operating times and thus higher infection rates. Applied Materials Today.

Magnetically actuated micro/nanorobots have attracted considerable research interests and have been developed rapidly in recent years because of their advantages, such as untouched control, insensitivity to biological substances, and precise positioning [23-26].Under the dominance of the magnetic fields, many investigators employed the micro/nanomachines assembled by DNA origami frameworks . by using Janus micropropellers. An important question is if and how the induced fields will benefit the patient as applied stimuli are not electric currents, as is the case with current SCS technology (Dones and Levi, 2018). Theorem). An overall benchmark on the magnetic actuation system and control method is discussed according to the applications of microrobots. Use of magnetic fields for additional capabilities beyond manipulation is presented. These concepts are discussed to describe the interactions between micro/nanorobots and magnetic fields. This maneuver can be impeded with complex anatomy, often seen in patients with degenerative spine disease, or for targets in which the SCS lead has to be placed within confined spaces such as the dorsal root ganglion (Caylor et al., 2019) (Figure 1B).
