Magnetic Shape-Forming Surgical Continuum Manipulator
Magnetic shape-forming surgical continuum manipulator (“CM”) comprising an elastomeric base material and a plurality of magnetic elements, the plurality of magnetic elements being located at a plurality of points along a length of the CM and each magnetic element having a predetermined magnetic profile, whereby the shape of the CM can be magnetically manipulated substantially along said length by the application of an external magnetic field and a magnetic field gradient.

POINT-OF-CARE MAGNETIC RESONANCE IMAGING SYSTEM FOR LUMBAR PUNCTURE GUIDANCE
A single-sided magnet and magnetic resonance imaging (“MRI”) system are portable and lightweight, enabling use as a point-of care (“POC”) MRI device. The portable MRI system includes a magnet assembly containing layers of magnet blocks, such as rare-earth magnet blocks. The magnet blocks are arranged in concentric rings in each layer, and surround a central aperture extending through the magnet assembly. The central aperture is sized to allow a medical instrument, such as a needle, to pass through the central aperture. The portable MRI system can therefore be used for image guidance in lumbar puncture (“LP”) and other medical procedures.
