This paper proposes an electrodeposition-based method to generate Alginate-Poly-L-lysine (PLL) microcapsules for 3D cell structures. Hepatic lobule shaped microcapsules of RLC-18 cells were produced for long-term culture to obtain desired morphologies of cell aggregates. The fabricated hepatic lobule models with high cell density are important to be applied for 3D assembly of biological cells for...
This paper presents a new in-vitro simulator that can simulate the new technology of three-dimensional digital subtraction angiography (DSA) to perform a cerebral aneurysm surgery. Then, propose a new technique for the numerical evaluation of the surgical tools applied within this interventional surgery to aid in the design and selection of surgical instruments. Initially, the in-vitro intravascular...
We present the fabrication of 3D porous micro-channel for artificial capillary blood vessel model to study the pressure of glomerulus in vitro. The 3D porous micro-channel was fabricated by direct laser writing to mimic the complex structure of capillary blood vessel. It was designed to connect with micro-channels which were fabricated by UV lithography process. The 3D porous micro-channel was made...
Simulator based evaluation has been used for medical licensing, intravascular tools evaluation and robotic catheter insertion systems research. However it is need to develop quantitative evaluation methods for the catheter trajectory inside vasculature phantoms. In this study we present two technologies developed for that purpose. First we present models of vasculature made of epoxy resin with higher...
This paper presents a sensor fusion between intravascular ultrasound (IVUS) and magnetic trackers for constructing the virtual reality three dimensional models of the blood vessels. We propose this approach for vasculature modeling as part of a guidance system relying on augmented reality for assistance during aortic stent graft deploy. This guidance will facilitate the alignment of the holes on the...
