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...)
Videos of Surgery Used to Teach Robot to Suture
Surgery has a reputation as being an intellectual profession, but a lot of the actual practice of surgery involves simple, routine tasks that are performed on nearly every patient. Suturing is one of those and a team of researchers from University of California Berkley and Intel thinks that it is possible to teach a robot […]
Samsung Releases RS85 Prestige Advanced Diagnostic Ultrasound
Samsung is releasing its top-of-the-line RS85 Prestige diagnostic ultrasound system. The device sports Samsung’s latest hardware and software technologies, such as Crystal Architecture, to produce high quality ultrasound images. Moreover, the system can run a dozen or so intelligent software features that fine tune image quality in specific s (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...)
3D Printed Liquid Crystal Elastomers for Mimicking Complex Biological Tissues
Researchers at the University of Colorado Denver have developed a method to 3D print liquid crystal elastomers so that they form complex structures with physical properties that match those of complex biological tissues, such as cartilage. The researchers hope that the technique will help with creating patient-specific implants to replace tissues t (Read more...)
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...)
Personalized Blood Flow Modeling Benefits from Virtual Reality Interface
Researchers at Duke University have developed a fluid dynamics simulator that can model blood flow within the body, including the motion of individual blood cells. The researchers hope that the system could eventually be used by clinicians to model blood flow for individual patients and help with treatment decisions, such as stent placement. By tes (Read more...)
OssoVR Lets Surgical Training Continue Virtually Despite COVID Limitations
Over the past few months, medical student and resident training has been severely limited due to Covid-19. However, knowledge, coordination, dexterity, and experience may not have to suffer because of quarantine and social distancing restrictions. OssoVR, a leading virtual reality surgical training and assessment platform, has been able to expand i (Read more...)
Soft Actuator and Sensor for Underactive Bladder Treatment
Researchers at the National University of Singapore have developed a soft sensor and actuator to monitor bladder volume and help empty it on-demand. The device is intended to be implanted on the bladder surface during a surgical procedure to treat patients who cannot completely empty their bladders voluntarily. Patients can suffer from an underacti (Read more...)
Electric Stimulation Gives Robot-Assistive Surgery a Sense of Touch
A team of researchers at Texas A&M have performed studies evaluating how electrical stimulation can help users control robots, for example helping surgeons steady their movements during robot-assisted procedures. They found, in 11 subjects, that small electrical stimulations to the fingertips can help users control the pinching of a hardwood bl (Read more...)

Brain-Computer Interface Lets Man with Complete Spinal Cord Injury Feel and Move His Hand
Spinal cord injuries can leave people paralyzed and without a sense of touch in much of the body. While there’s been a tremendous amount of work in the past decade to overcome paralysis by using brain-computer interfaces to bypass damaged spinal cords, providing a sense of touch is a necessity for truly proper treatment. As […]
Lungpacer Diaphragm Pacer Gets FDA Emergency Use Authorization for COVID-19
Lungpacer Medical, based in Vancouver, Canada, announced that its Diaphragm Pacing Therapy (DPT) System received FDA Emergency Use Authorization for use in weaning COVID-19 patients off of ventilators. Patients on prolonged mechanical ventilation may experience diaphragm disuse atrophy and ventilator-induced diaphragmatic dysfunction (VIDD), which (Read more...)
Cochlear Implant Turned-On Remotely to Give Child Hearing
All sorts of medical procedures have to wait to be performed due to the ongoing COVID-19 pandemic. Since some procedures are done in several steps, often separated by weeks or months, there are patients out there that cannot complete the next steps of their therapies. Cochlear implants, which stimulate the auditory nerve to produce hearing [&hellip (Read more...)
Xenoscope Disposable 5mm Laparoscope FDA Cleared
Xenocor, a Salt Lake City company, won FDA clearance for its Xenoscope 5mm articulating disposable laparoscope. The device requires no sterilization re-processing between procedures and is thrown away after it’s used, avoiding the necessity for servicing contracts. The entire system being quite compact, it doesn’t need its own large ima (Read more...)
Camera Images Blood Perfusion at High Resolution Thanks to Pulse Oximeter
How blood moves throughout the body and into the smallest capillaries is hard to observe using existing imaging methods. Yet, poor blood perfusion can be an indicator for a variety of medical conditions, potentially serving as a diagnostic tool and a way to help manage diseases. Infrared thermography is a decent tool for this, but […]
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...)
Iris Needle Guidance for Lumbar Punctures: Interview with Dev Mandavia, CEO of Ethos Medical
Ethos Medical, a startup founded by Georgia Tech alumni, has developed the Iris needle guidance system to assist clinicians in successfully performing lumbar punctures. The system allows a clinician to visualize the needle traveling through tissue in real time. Tracking the needle path in this way is intended to improve the success rate and reduce (Read more...)
