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 to print […]

Wireless Lumee Oxygen Platform Cleared in EU
The European Union cleared Profusa’s Wireless Lumee Oxygen Platform, a system designed to measure tissue oxygen levels in patients with diseases such as peripheral artery disease and critical limb ischemia. The wired version of the Lumee was cleared in Europe back in 2016 and the new device fundamentally works the same. It consists of a […]
SELUTION SLR Drug Eluting Balloon Cleared by EU
MedAlliance, a Swiss company, won the EU CE Mark clearing its SELUTION SLR sirolimus-eluting balloon for use in treating peripheral vascular disease. This is the first CE Mark that the company has received and the clearance applies to SELUTION SLR devices in sizes from 2.0 x 20mm to 7.0 x 150mm. MedAlliance’s technology allows sirolimus, […]
Nanoparticles Direct Immune System to Scrub Atherosclerotic Plaques
The buildup of plaques within blood vessel walls is the underlying cause of strokes and heart attacks. These plaques contain many dead or dying cells that are not flushed out by the immune system fast enough. Now, researchers from Stanford are reporting on a new drug-carrying nanoparticle that can seek out atherosclerotic plaques and stimulate […]
Mindray’s New High End Point of Care Ultrasound
Mindray is releasing a new point-of-care ultrasound system, the TE7 ACE. The device, intended for a variety of applications including emergency, critical care, and anesthesia, features a large color touchscreen, fluid management features, needle guidance toolkit, and electronic medical records connectivity. The company claims that the fluid measurement algorithms within this ultrasound are based on […]
Argon Releases Universal IVC Filter Removal Kits
Argon Medical Devices, a company based out of Frisco, Texas, is launching two kits for retrieving inferior vena cava (IVC) filters. IVC filters are used to prevent pulmonary embolisms, but when a patient no longer needs one it has to be removed. The two Argon kits are designed to fish out any retrievable IVC filter […]
Cook Releases TriForce Crossing Set for Complex Peripheral Disease
Cook Medical is releasing in the United States its TriForce Peripheral Crossing Set, devices made to support percutaneous wire guides while performing interventions within the peripheral vasculature. In addition to helping to directly treat obstructions, the devices can also be used to inject radiopaque angiography contrast media to image the vasculature being worked on. The […]
Microsure, a Dutch Microsurgery Robotics Firm, at CES 2020
Among the myriad of consumer gadgets at CES 2020, we ran into a Dutch maker of microsurgery robotic equipment. Microsure makes the MUSA robot, which already has the CE Mark in Europe. Here’s a company rep giving us an introduction:

Fully Disposable Endovascular Robot Unveiled
Microbot Medical, a company with offices in Massachusetts and Israel, is about to release the world’s first fully disposable endovascular surgical robot. The LIBERTY device is intended for use in a variety of cardiovascular, neurovascular, and peripheral vascular procedures, manipulating catheters in a fly-by-wire way. Since it can be operated remotely, clinicians can be kept […]
Super-resolution Photoacoustic Microscopy to Find Clogged Blood Vessels
Researchers from Pohang University of Science and Technology in South Korea have developed a new photoacoustic imaging system that can visualize microvasculature without a contrast agent. The new system is 500 times faster than conventional photoacoustic imaging, and features a spatial resolution enhanced by 2.5 times. This system can one day help improve detection and […]
Nanoparticles to Spot Vascular Calcification in Atherosclerosis
Atherosclerosis affects most of us by a certain age, and it is the underlying cause of most cardiovascular diseases. The condition results in arteries being coated with plaques and fatty deposits, as well as being chronically inflamed. While vascular constrictions aren’t good for anyone, it is the thrombi (blood clots) that detach from these formations […]
Interview with Medtronic’s Mark Pacyna on Approval of IN.PACT AV DCB for Failing AV Fistulae
End-stage renal disease (ESRD) patients experiencing kidney failure typically require hemodialysis in order to artificially remove fluid and waste from blood and maintain appropriate electrolyte concentrations. For many patients on hemodialysis, an arteriovenous (AV) fistula is created to link an artery to a vein. Veins are too fragile for frequent access, but arteries are too […]
Robotic System for Deep Endovascular Instrument Guidance
Researchers at the Polytechnique Montréal Nanorobotics Laboratory in Canada have developed a new method to guide endovascular instruments into complex vascular structures that were hitherto inaccessible to endovascular surgeons. The technique involves moving the patient and the endovascular instrument using a robotic platform within a magnetic field. Endovascular surgery has enabled minimally invasive approaches for […]
IN.PACT AV Drug Coated Balloon for Dialysis Patients to Heal AV Fistulaes
Medtronic has won FDA approval to introduce its IN.PACT AV drug-coated balloon as a treatment option for failing arteriovenous (AV) fistulae. People with non-functional kidneys who undergo dialysis receive AV fistulae, which link an artery to a vein. Veins tend to be too fragile for regular access, but arteries are too deep. Creating an AV […]
Butterfly Network Expands Applications for Smartphone-Connected Ultrasound: Interview
Butterfly Network, the digital health unicorn democratizing medical imaging, is continuing to add new applications for its handheld, single probe, smartphone-connected ultrasound technology. The Butterfly iQ, the multi-purpose pocket-sized ultrasound, won FDA clearance a couple years ago and earlier this year received the CE Mark, clearing it for distribution in Europe. The innovation found within […]
Omega FluoroShield FDA Cleared to Reduce Radiation Exposure
Omega Medical Imaging, a firm based in Sanford, Florida, has won FDA clearance for its FluoroShield technology, as well as the 2020 Cardiac Flat Panel Detector. FluoroShield automatically aims the radiation beam across the area of interest during interventional procedures utilizing fluoro or cine (short X-ray movies of the beating heart) imaging. This is thanks […]
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 network and become […]

Bruin Biometrics Is on a Mission to End Pressure Ulcers: Interview with CEO Martin Burns
Earlier this year, Medgadget reported on the FDA’s clearance of the SEM Scanner, a device created by Los Angeles-based Bruin Biometrics (BBI). The SEM Scanner is a wireless, handheld device that detects changes in sub-epidermal moisture as an indicator of risk for developing a pressure ulcer. Moisture can indicate the presence of localized edema and […]
3D Printed Cells and Bioinks for Making Implantable Blood Vessels
Researchers based in South Korea and Hong Kong have developed a method to create biomimetic blood vessels by directly 3D printing vascular cells and bioinks containing collagen and vascular tissue extracellular matrix components. The resulting constructs closely mimic natural blood vessels, suggesting that such techniques could pave the way for custom vascular grafts to treat […]
