Wireless Sensor Measures Deep Tissue Oxygen Levels

Researchers at the University of California, Berkeley have developed an ultrasound-powered implantable sensor that can measure oxygen levels in tissues deep within the body and transmit these data to an external device. The technology could be useful in monitoring transplant viability or oxygen exposure in preterm infants. It also has potential to (Read more...)

Heart Patch Helps Grow New Vessels Post Myocardial Infarct

Researchers at the Pohang University of Science & Technology (POSTECH) in South Korea have developed a hydrogel patch system that allows for sophisticated sequential release of growth factors that stimulate angiogenesis. The sequential cascade of growth factors mimics the natural process in the body and the researchers hope that the technology (Read more...)

Tendon-Inspired Sutures Protect Fragile Tissues

Researchers at McGill University in Canada have developed bioinspired sutures that mimic the structure of human tendons. The gel-covered sutures are slippery and tough, reducing the damage caused by conventional sutures when used on soft tissues. Interestingly, the gel surface of the sutures may allow for advanced applications such as drug delivery (Read more...)

Medical Robotics and The Future of Surgery: Interview with Tracy Accardi, VP of R&D at Medtronic

Medtronic has been a key player in the minimally invasive surgery space for the last few decades, and has made great strides more recently in robotic surgery with last year’s acquisition of Digital Surgery. As a quick reference point: despite the many benefits of robotic-assisted surgery (RAS), only 3% of surgeries around the world are [&hell (Read more...)

Dexter Surgical Robot Works with All Laparoscopy Tools

Robotic laparoscopic surgery is now widely available, with Intuitive Surgical’s da Vinci systems being the most common robots out there. These systems typically require specialty tools provided by the robot manufacturer, and the selection is quite limited compared with the wide array of conventional laparoscopic tools that exist. Now, Distalm (Read more...)

PREVENA RESTOR AXIO•FORM Negative Pressure Wound Therapy: Interview with Dr. Ronald Silverman, 3M’s Chief Medical Officer

3M recently announced a new negative pressure wound therapy system called PREVENA RESTOR AXIO•FORM Incision Management System, which has been available since August. The new system expands the amount of time that negative pressure can be applied to a total of 14 days, with a dressing change at 7 days. The included disposable dressings are [&he (Read more...)

Symani Microsurgical System Cleared in Europe

Medical Microinstruments (MMI), a company based outside of Pisa, Italy, won the European CE Mark of approval for its Symani robotic surgical system. The product provides 7-20X scaling of hand movements, automatically removing tremors to allow for safe microsurgical and supermicrosurgical procedures. It is hoped that this impressive new device can h (Read more...)

Portable Surgical Robot for Minimally Invasive Procedures: Interview with John Murphy, CEO of Virtual Incision

Virtual Incision, a company based in Lincoln, Nebraska, has developed the miniaturized in vivo robotic assistant (MIRA) platform to perform minimally invasive abdominal surgeries, such as colon resections. Conceived as a small and accessible surgical robotic support device, the miniaturized system is considerably less expensive than current robotic (Read more...)

Octopus-Inspired Sucker for Tranplanting Cell Sheets

Researchers at the University of Illinois have developed a ‘sucker’ to pick up and transfer thin cell or tissue sheets that are intended for therapeutic purposes, such as wound healing or tissue grafting. Inspired by octopus suckers, the device can gently manipulate the delicate sheets without causing damage, and uses heating and a temp (Read more...)

Supportive Gel Allows for Bioprinting of Complex Shapes

Researchers at Penn State have developed a supportive gel that allows for printing of complex shapes using cell aggregates. The gel provides a supportive matrix during the printing process, and permits the researchers to place the aggregates wherever they want. This technique could pave the way for printed replacements for tissues and organs. Biopr (Read more...)

Wearable Ozone Therapy Device for Chronic Wound Treatment

Researchers at Purdue University have developed a wearable device that can administer antibacterial ozone gas to chronic wounds to help disinfect them. The technology could allow people to disinfect chronic wounds at home, and would be helpful in cases where wounds have been colonized by drug-resistant bacteria and aren’t responding to antibi (Read more...)

Origami Surgical Manipulator to Perform Microsurgeries

Robotic surgical assistants, such as the da Vinci systems from Intuitive Surgical, are now routinely used during laparoscopic procedures to improve operative precision, flexibility, and to manipulate multiple tools at once. Such devices can be quite complex inside and so they tend to be quite large, often taking up much of the space of an [… (Read more...)

Tiny 3D Printed Cubes Serve as Scaffolding for Broken Bones

A good deal of orthopedic bone repair surgeries involve injecting powders or pastes, to serve as scaffoding, into fractures. Now a collaboration between scientists at Oregon Health & Science University (OHSU), University of Oregon, New York University, and Mahidol University in Thailand has led to the development of a Lego-like 3D printed scaff (Read more...)

Nanostimulators Activate Damaged Tissue to Heal Itself

Peripheral artery diseases and injuries to tissue reduce the amount of oxygen that reaches the affected muscles. Such ischemia is difficult to treat, as new vessels are required to carry more oxygen into damaged tissues. Stem cells derived from fat tissues have been shown to excrete substances that spur angiogenesis and calm nearby inflammation. Bu (Read more...)

Easily Removable Surgical Tape to Seal Internal Wounds

Researchers at MIT recently developed an adhesive tape that allows surgeons to seal internal wounds and that can readily stick to slippery internal surfaces, as a potential replacement for sutures. However, the adhesive worked a little too well, and was difficult to remove or adjust without causing irritation or tissue damage. Now, the research tea (Read more...)

Printed Soft Objects for Shape-Shifting Biomedical Implants

Researchers at Rice University have developed a method to 3D print soft structures that can reversibly change their shape in response to external stimuli, such as heat or an electric current. The researchers have dubbed their technique “reactive 4D printing” and it could have potential in creating adaptive biomedical implants that can r (Read more...)

Microneedle Patch for Delivering Stem Cells Into Tissue

Researchers at the Terasaki Institute in Los Angeles have developed a microneedle patch to deliver mesenchymal stem cells (MSCs) into the skin. The biodegradable needles contain a gelatin matrix in which MSCs can survive. Once applied to the skin and removed, the needles detach from the patch and remain within the tissue. The hard outer […]
