Through this research, highly porous open cell foams were fabricated with Polylactide (PLA) and Polyethylene glycol (PEG) using compression molding combined with particulate leaching technique. Salt and water soluble polymer were used as the particulates. The pore size of the foam structure is controlled by the particulates size and higher interconnectivity(More)
We present a kinetostatic model for a needle-sized notched tube continuum joint design, and examine the impact that the design parameters have on both stiffness and joint kinematics. The joint is fabricated by removing a series of asymmetric notches from a metal tube. By fixing a cable to the distal end of the tube, and routing this tendon through the(More)
A simulation-based approach to the design of procedure-specific dexterous neuroendoscopic continuum instruments for endoscopic third ventriculostomy and tumor biopsy is proposed. Given pre-operative CT and MRI images, the algorithm returns instrument design specifications including lengths, curvatures and alternative positions for the surgical incision(More)
