(F) Origami-like However, when navigating within the spinal epidural space, support from surrounding tissue does not exist and the catheter body can move relatively freely within the space. Magnets placed external to the patient's body are used to guide a surgical probe equipped with a magnetic tip. To date, neurosurgical applications of MNS have been limited to preclinical studies (Hong et al., 2019, 2021), while spinal applications remain unexplored. A variable stiffness catheter design could be a solution to this optimization problem (Figure 2B).

Copyright 2016 WILEY-VCH MNS also allow for steering control at longer distances, e.g., the lead could be inserted at the thoraco-lumbar level (which is safer than more cranial insertion points) and guided to the cervical level, or a combined cervical and thoracic lead could be guided through a single entry and navigated to both targets. When the lead has been successfully navigated to the target location, surgeons can proceed as usual and connect an IPG manually.

Even with the lowest reported incidence of 2% (Gazelka et al., 2015), when considering the high volume of SCS procedures worldwide, this percentage still corresponds to a considerably high number of patients. Although a few biocompatible magnetostrictive and piezoelectric materials exist (Wang et al., 2010; Rajabi et al., 2015; Ribeiro et al., 2018), the compatibility of these materials in the spinal epidural space or subarachnoid space needs to be investigated in future research as literature suggests that different tissue types show different cellular responses (Duliska-Litewka et al., 2019). This process could be time-consuming until optimal lead placement is achieved and it creates positional discomfort for the patients since they are awake and in the prone position. Verification of the location of the SCS electrode with fluoroscopy can be obtained if desired. an island of, Representative pollutant removal by active MagRobots. In a recent study, Hong et al.
