Additive manufacturing/3D printing of medical devices is becoming more commonplace, a 3D printed drug now commercially available, and bioprinting poised to transition from laboratory market. Despite the variety technologies enabling these products, US Food Drug Administration (FDA) charged with protecting promoting public health by ensuring products are safe effective. To that end, we presenting FDA's current perspective on additive ranging those regulated Center for Devices Radiological...
Background: Wrist motion is dependent on the complex articulations of scaphoid and lunate at radiocarpal joint. However, much what known about joint limited to anatomically defined motions flexion, extension, radial deviation, ulnar deviation. The purpose present study was determine three-dimensional in vivo kinematics throughout entire range wrist motion, with special focus dart thrower's from extension flexion. Methods: capitate, scaphoid, were calculated serial computed tomography scans...
Objective. The Food and Drug Administration's (FDA) Center for Devices Radiological Health (CDRH) believes it is important to help stakeholders (e.g., manufacturers, health-care professionals, patients, patient advocates, academia, other government agencies) navigate the regulatory landscape medical devices. For innovative devices involving brain–computer interfaces, this particularly important. Approach. Towards goal, on 21 November, 2014, CDRH held an open public workshop its White Oak, MD...
As the medical applications of three-dimensional (3D) printing increase, so does number health care organizations in which adoption or expansion 3D facilities is under consideration. With recent advancements technology, practitioners have embraced this powerful tool to help them deliver high-quality patient care, with a focus on sustainability. The use hospital clinic at point (POC) has profound potential, but its not without unanticipated challenges and considerations. authors provide basic...

We have investigated the potential of tissue phantoms fabricated with thermosoftening- and photopolymerization-based three-dimensional (3D) printers for use in evaluation biophotonic imaging systems. The optical properties printed polymer samples were measured compared to biological tissues. Phantoms subsurface channels as small 0.2 mm diameter imaged microscopy, x-ray microtomography, coherence tomography characterize morphology. These then implemented evaluate penetration depth a...
Abstract Background 3D printing (3DP) has enabled medical professionals to create patient-specific devices assist in surgical planning. Anatomical models can be generated from patient scans using a wide array of software, but there are limited studies on the geometric variance that is introduced during digital conversion images models. The final accuracy printed model function manufacturing hardware quality control and variability multiple steps convert printable format. This study provides...
The adoption of three-dimensional (3D) printing is rapidly spreading across hospitals, and the complexity 3D-printed models devices growing. While exciting, rapid growth increasing also put patients at increased risk for potential errors decreased quality final product. More than ever, a strong management system (QMS) must be in place to identify errors, mitigate those continually enhance product that delivered patients. continuous repetition traditional processes care, without insight into...
The emerging technique of rapid prototyping with three-dimensional (3-D) printers provides a simple yet revolutionary method for fabricating objects arbitrary geometry. use 3-D printing generating morphologically biomimetic tissue phantoms based on medical images represents potentially major advance over existing phantom approaches. Toward the goal image-defined phantoms, we converted segmented fundus image human retina into matrix format and edited it to achieve geometry suitable printing....
Implantable motor neuroprostheses can restore functionality to individuals with neurological disabilities by electrically activating paralyzed muscles in coordinated patterns. The typical design of neuroprosthetic systems relies on a single multi-use device, but this limits the number stimulus and sensor channels that be practically implemented. To address limitation, modular neuroprosthesis, "Networked Neuroprosthesis" (NNP), was developed. NNP system is first fully implanted...
A new acellular, natural, biodegradable matrix has been discovered in the cholecyst-derived extracellular (CEM). This is rich collagen and contains several other macromolecules useful tissue remodeling. In this study, principal material axes, fiber orientations, biaxial mechanical properties a physiological loading regime were characterized. Fiber direction was determined by polarized light microscopy, axes degree of anisotropy mechanically. Macroscopic equibiaxial strain tests then...
Abstract Kinematic interpolation is an important tool in biomechanics. The purpose of this work to describe a method for interpolating three-dimensional kinematic data, minimizing error while maintaining ease calculation. This uses cubic quaternion and hermite fill gaps between data points. Data sets with small number samples were extracted from larger set used validate the technique. Two additional types applied then compared interpolation. Displacement errors below 2% using achieved 4%...
An aqueous hyaluronic acid (HA(aq)) pericellular coat, when mediating the tactile aspect of cellular contact inhibition, has three tasks: interface formation, mechanical signal transmission and separation. To quantify interfacial adhesive behavior HA(aq), we induce simultaneous formation separation between HA(aq) a model hydrophobic, hysteretic Si-SAM surface. While surface tension γ remains essentially constant, depend greatly on concentration (5 ≤ C 30 mg mL−1), molecular weight (6 MW 2000...
Horseshoes influence how horses’ hooves interact with different ground surfaces, during the impact, loading and push-off phases of a stride cycle. Consequently, they impact on biomechanics proximal limb segments upper body. By implication, shoe surface combinations could drive changes in magnitude stability movement patterns horse-jockey dyads.
