When wounds are quickly and securely closed following injury, healing is faster, risks of infection are minimized, and more serious sustained injury can be prevented. A new type of surgical glue has been created to do that in a fast-acting and reliable manner. It may even change first aid and medical response procedures at car accidents, in combat zones, and at emergency sites.

Fast Forming For Better Wound Healing
MeTro behaves like a silicone sealant, much like those used to create a water seal in bathrooms and other household applications, but it works even faster. Once administered to human tissue, MeTro rapidly forms to gel-like thickness and serves to seal a wound. This action occurs as highly elastic proteins and light sensitive molecules are set after being exposed to UV light. The gel takes just 60 seconds to thicken and solidify, which is vital to blocking out bacteria in urgent situations.
Modifiable For Recovery Times
While MeTro securely remains in contact with the tissue to which it’s applied, it retains some elasticity so it moves with the patient and prevents wounds from reopening. The treatment can also be modified with a degrading enzyme that determines how soon MeTro will begin to breakdown. Whether sealing is required for minutes or months, the gel can be catered to appropriate recovery times.

For Use On Difficult To Treat Sites
Northeastern University and Australia’s University of Sydney Researchers responsible for creating MeTro have also shown how it can be used on treatment sites that are otherwise difficult to seal due to exposure to bodily fluids and natural expansion and contraction. The substance shows potential for use on vital areas that are challenging to stitch, suture, or bandage, such as internal organs like the lungs and heart.
As MeTro has been tested successfully on pigs, researchers are now focusing on trials in humans. Will their development render conventional wound healing and closing treatments obsolete? Comment and share your thoughts.
Medical Device Manufacturers Use Robots For Speed, Safety, And Cleanliness
Robotic equipment in medical device production lines allows companies to maintain high standards of cleanliness, worker safety, product consistency, and speed. From heart valves to artificial joints to surgical equipment, robots increasingly play an integral role in medical device manufacturing.
Robots Limit Biological Contamination
Manufacturing facilities have long contended with the contamination issues introduced by human workers. Robots allow for the removal of the human element from many production areas. In addition to maintaining sanitary environments, robotic installations have aided manufacturers during the coronavirus pandemic. The CEO of MICRO said that greater integration of robots in workflows helped to limit human-to-human contact among workers.
Precise And Consistent Results
On top of sanitation, medical devices require high degrees of precision. Robots are capable of extreme dexterity that a human worker cannot replicate with consistency. Medical device companies draw upon the robotic developments pioneered by the electronic and automotive industry that turned to robots to build miniature components. New production processes for building artificial heart valves have incorporated small robots that perform highly detailed work on small parts with repeatable accuracy.
Elimination Of Workplace Sharps Hazards
A multitude of medical devices and tools involve very sharp edges. Fabrication of these instruments historically exposed workers to the risk of serious cuts. The installation of robots to grind, deburr, and package medical sharps reduces risks of worker injury. Workers focus instead on monitoring operations while robots produce precision goods at speeds beyond what human workers could achieve.
Robots Aid Industry Expansion
Tecomet Inc. in Boulder, Colorado, is in the middle of expanding operations. In addition to hiring more workers, the company will add another 25 machines, including robotic systems, to its new facility. Longer-term, the company anticipates that it will manufacture robots for clients operating cleanroom facilities at hospitals.
In your experience, how has robotic equipment overcome production challenges or expanded opportunities for new business?

More Flexible Electronic Manufacturing Means Better Medical Monitoring
To fit more reliably and comfortably when worn, wearable electronics must be flexible while retaining their ability to collect and communicate data. Conventional sensors and other electronic components, even when made very small, don’t often offer these attributes, which can limit their use as medical devices. A new additive manufacturing method from researchers at Harvard University’s Wyss Institute for Biologically Inspired Engineering makes it possible to create useful monitoring electronics that fit more comfortable and move naturally when worn directly on the skin.

Hybrid 3D Printing
Through a process that the researchers refer to as hybrid 3D printing, electronically conductive inks can be incorporated into wearable devices that are not only soft and flexible, and therefore comfortable to wear, but can also be stretched and still perform reliably. The conductive ink is made from thermoplastic polyurethane (TPU) and contains electrodes, which can be layered with a soft, flexible substrate through an additive manufacturing process. As the ink solidifies, the result is a conductive, highly flexible, and fully functional circuit that can be used for a range of medical needs.

Custom Fit For The Patient And Diagnosis
Since these soft sensors can be printed to just about any shape, and with the position of the conductive features determined during the manufacturing process, it’s possible to create medical sensory devices that fit the patient as well as the specific data to be collected. Researchers are able to collect information from a wearer’s movement or from the application of pressure and easily read the resulting data in a number of ways.
The hybrid 3d printing process has been noted as significant for the flexible and versatile devices it yields, as well as its relative low cost. While the resulting products are currently in the prototype stage, researchers have called this a first step in creating robust and affordable wearable electronics that are also comfortable and customized.

3D Printed Titanium SI Implant Gets FDA Approval
The FDA has just cleared a new type of medical implant made from 3D printed titanium. Developed by SI-BONE, a California-based medical device company, the iFuse 3D implant system can now be used to help treat sacroiliac (SI) joint dysfunction. According to the company, the device is the first of its kind as a 3D printed titanium implant designed for use in the SI joint.

Meant To Improve Bone Growth And Regrowth
The iFuse implant is made with a porous structure. This unique form is meant to improve bone growth, regrowth, and through growth in between the sacrum and the ilium bones in the pelvis, where the SI joint is located. Some individuals with lower back pain also suffer from SI joint dysfunction, as this part of the skeletal system directly supports the spine. Per SI-BONE, between 15 and 30 percent of lower back pain sufferers experience that pain as a direct result of SI joint dysfunction.
Enhancing And Expanding On Successful Features
With the non-3d printed iFuse implant being used in over 26,000 procedures over the last six years and gaining the support of over 50 peer-reviewed publications, the iFuse 3D version has now been cleared for use by the FDA. The new implant is created using an Arcam EBAM machine, which allows for enhanced surface characteristics that foster bone regrowth. The increased surface area created through the iFuse 3D plays an integral role in this function and greatly expands on the features of the non-3D printed iFuse Implant.

Possibilities Through Printable Titanium
The ability to 3D print using medically advantageous materials like titanium has opened doors for the creation of more advanced medical devices and implants. Portions of the human skull, rib cage, jaw, and spinal cord are just a few of 3D printed prosthetics and implants that can now be made from titanium.
With the potential to create more devices like this, and greater acceptance and approval by regulatory agencies, what 3D printed medical aids will be available next? Comment and share your thoughts on this development.
