Medical 3D Printing and Additive Manufacturing: Going From Why to How

3D printing has been utilized in the medical industry for over 20 years. In recent years, the number of applications, utilization, and utility have increased exponentially. This increase has been driven by two key factors: (1) crossing the chasm from “how to print” to “why adopt 3D printing and additive manufacturing”, and (2) the dramatically increased selection of technologies and materials that meet the needs of medical professionals.

Selecting Miniature Motors for your Medical Devices

The creation of small, portable infusion pumps opened a new chapter in medical care. A patient can receive carefully metered and timed doses of medicine, without requiring a visit to the medical practitioner, allowing life to be less restrictive. Ambulatory pumps have been developed to deliver insulin, nutritive supplements and anticancer drugs.

Breaking Boundaries: Bioabsorbable Polymers in Device Design

It is well known that programming the performance of a bioabsorbable medical device is paramount to its success. But did you know that a large part of this programming takes place at the component level?

Avoiding Common Mistakes in Extractables/Leachables Program Design

Mistakes in program design for extractables/leachables testing can lead to significant delays, rounds of questions, and the need for additional testing. And, in some cases, all of the extractables/leachables testing may need to be repeated. To avoid these costly mistakes, it is important to understand the current standards as well as the current interpretations and opinions from regulators interpreting these standards. In this whitepaper the experts from WuXi AppTec discuss the current standards, interpretations and will provide you with tips to avoid common mistakes when designing your program.

Retinal Light Processing Using Carbon Nanotubes

This chip can be used as an electrical or optical sensor for the retina. Ames Research Center, Moffett Field, California NASA has patented a new technology called the Vision Chip, an implantable device that has the potential to restore or supplement visual function in a diseased or damaged retina. This technology could benefit millions of people in the US and globally who suffer from degenerative diseases of the eye’s retina such as age-related macular degeneration (AMD), retinitis pigmentosa (RP), and, in some cases, diabetic retinopathy. The Vision Chip is targeted to treat AMD and other degenerative diseases of the retina by replacing a compromised retinal photoreceptor system with an array of equivalent external photoreceptors and carbon nanotube (CNT) “towers” (bundles of CNTs) that provide a pathway to transmit signals from the external photoreceptors to an active layer of retina.

Provision of Carbon Nanotube Buckypaper Cages for Immune Shielding of Cells, Tissues, and Medical Devices

This method may prevent the rejection of transplanted cells and tissue. Ames Research Center, Moffett Field, California NASA has patented a new technology that may prevent the rejection of transplanted cells and tissues. The human immune system identifies and rejects non-host cells and tissues with high efficiency. The new invention involves the fabrication and use of carbon nanotube buckypaper (CNTBP) “cages” for immune shielding. This approach promotes and supports a variety of useful biological processes that are difficult or impossible when cells or tissue are maintained in culture outside the body. It allows for the transplantation of cells or tissues from unrelated donors or from unrelated species (xenografts) into host subjects with dramatically reduced potential for rejection and/or the use of immunosuppressive therapies, which can be highly toxic. Current strategies for islet cell transplantation, for example, have shown marginal success due to limited graft survival, even with immunosuppressive therapy.

Rapid Polymer Sequencer

Maximum resolution will be improved at least 100-fold compared to biological ion-channel measurements. Ames Research Center, Moffett Field, California Solid-state, nanopore-based analysis of nucleic acid polymers is the only technique that can determine information content in single molecules of genetic material at the speed of 1 subunit per microsecond. Because individual molecules are counted, the output is intrinsically quantitative. The nanopore approach is more generalized than any other method, and in principle may be used to analyze any polymer molecule, including proteins. The approach to the development of a solid-state nanopore device is novel in the use of nanofabrication, nanoelectric components, and high-speed signal acquisition.
