Introduced in the 1970s, Spinal Cord Stimulator (SCS) devices have played a crucial role in managing a wide range of chronic pains, particularly back and leg pain. Currently, cylindrical and paddle leads are two primary types of leads widely used for pain management. Cylindrical leads, due to their small size, are susceptible to movement and migration, leading to device displacement and associated complications that often necessitate additional surgical interventions. On the other hand, paddle leads offer a larger surface area and secure placement but require a relatively large incision for device placement. To address these limitations, a new SCS device has been developed that contains a low-profile, deployable, and retrievable. This device is able to collapse into a 14-gauge needle (1.5-1.6 ππ in diameter), and then expand into a paddle-shape lead in the affected site after the deployment. Using advanced manufacturing processes, the first prototype is fabricated, and the deployment procedure is validated. This novel SCS design effectively prevents device dislocation and migration, while also providing a larger surface area for minimally invasive pain management.
