Magnetic Tracking System for Flexible Surgical Robots

Researchers at the University of California San Diego have developed a magnetic tracking system for surgical robots to operate with dexterity within the body. The technology does not require patient or clinician exposure to radiation, and is much less expensive that pre-existing monitoring techniques. A magnet is embedded in the tip of the robot an (Read more...)

SX-One MicroKnife Makes Carpal Tunnel Release a Minimally Invasive Procedure: Interview with CEO Dr. Darryl Barnes

Carpal tunnel syndrome is a fairly common diagnosis in the United States, affecting approximately three to six percent of adults. Symptoms include pain, numbness, and tingling along the thumb, index, and middle fingers. For severe or refractory cases, the best treatment is surgery. However, because open surgery requires anesthesia and many weeks of (Read more...)

New Non-Toxic, Printable Biomedical Material Developed

Synthetic dry elastomers are polymeric materials that feature cross-linked networks that form into random and unordered shapes and textures. These materials have a host of properties that are applicable in biomedicine, but the randomness of their internal structures at different scales makes it difficult to actually use these elastomers. Now, resea (Read more...)

Universal Biomedical 3D Printing Ink Developed

3D printing is already used in medicine in many applications, but there’s still a great deal that custom-built implants could offer to patients. Bioinks, the materials from which bespoke implants can printed, may be the most important focus of research aimed at expanding the use of additive manufacturing, another term for 3D printing, in medi (Read more...)

Device Prints Scaffolds Inside Wounds to Replace Lost Tissue

3D printing of artificial scaffolds intended to replace injured tissues has become a ballyhooed technology that’s yet to prove itself in clinical practice. One issue that complicates things is that the scaffolds have to match the volume that they’ll be replacing, in both shape and the direction in which cells will have to grow. To [&hel (Read more...)

Microsure MUSA Robot Used for First Time on Real Patients

In a world first, clinicians at Maastricht University have used a robot to perform “supermicrosurgeries”, which involved operating on vessels as small as 0.3 mm in diameter. The procedures were conducted on women with lymphedema, a condition that arose as a result of breast cancer, whose lymphatic vessels were connected to veins to prov (Read more...)

New Customizable Bio-Ink for Printing Organs, Tissues

3D printing of tissues and organs requires a bio-ink that can host the living cells that are required for every unique application. A viable construct requires an extracellular matrix that will have the right mechanical and biochemical properties for the intended cells. Researchers at Rutgers University believe they’re on track to being able (Read more...)

Handheld 3D Bioink Printer for Wound Healing

Researchers at the University of Toronto have developed a handheld 3D printer that can deposit a stem cell-loaded bioink onto wounds, such as burns, to promote tissue healing. The device acts like a paint roller, and a clinician could use it to deposit the biomaterial in even stripes on a wound surface. A recent study […]

MolecuLight FDA Cleared to Detect Bacteria Infected Wounds

Knowing whether a wound is infected by a bacterial colony is important for monitoring patients and deciding the course of treatment. Currently, the standard of care is simply to assess the clinical signs and symptoms (CSS) related to the wound in question, but bacterial infections of wounds are typically not obvious until they’re at an [&hell (Read more...)

Electrospinning Drug Delivery Bandages Directly Onto Wounds

Electrospinning is a maturing manufacturing technology that is already being used in medicine to produce unusual materials with novel properties. It involves melting a polymer and extruding it through a narrow nozzle, while an electric field is used to pull and spin the polymer into a very fine mesh. When a biocompatible polymer is used, […]

Scientists 3D Print Vascularized Artificial Skin

Researchers from Rensselaer Polytechnic Institute have developed a new method to 3D print living skin with built-in blood vessels. This living skin construct is cultured in vitro and develops into an interconnected microvascular network underneath a layered barrier of skin cells. in tests on mice, the grafts connect with the animals’ vascular (Read more...)
