Cracking Calcium in Arteries Using Sound Waves: Interview with Shockwave Medical’s Scott Shadiow

Shockwave Medical, a medtech company based in California, has developed a technique called intravascular lithotripsy, which involves delivering sonic waves to calcified plaque in an artery in much the same way that sound waves have been used to treat kidney stones for many years. The idea is to safely crack the calcified deposits so that […]

Steerable Catheter to Navigate Tortuous Blood Vessels in Brain

A team at University of California San Diego invented a way to make steerable catheters that can more precisely navigate the tortuous architecture of the brain vasculature. The device was bioinspired by delicate structures found in nature, including flagella and insect legs, and uses principles from soft robotics to create a hydraulic steering syst (Read more...)

Levita Robotic Platform: Interview with Alberto Rodriguez-Navarro, CEO of Levita Magnetics

Levita Magnetics, a California-based company that specializes in laparoscopic systems, has recently announced that its Levita Robotic Platform, a surgical robot that is still in development, has been used to perform surgery on a patient for the first time in a hospital in Chile. The robot uses similar magnetic technology as in the company’s h (Read more...)

Ultrasound Patch Monitors Blood Flow

Researchers at the University of California San Diego created an ultrasound patch that can measure blood flow in vessels as deep as 14 cm within the body. The stretchy patch can be applied to the skin and may help clinicians to monitor and diagnose various conditions, including blockages that could cause an infarct. The patch […]

Aortic Occlusion to Enhance Blood Flow to Brain and Heart: Interview with Habib Frost, CEO of Neurescue

Neurescue, a medtech company based in Denmark, created the NEURESCUE system, a balloon catheter designed to occlude the aorta, resulting in a significant increase in blood flow to the heart and brain. The mechanism is intended to provide emergency treatment for patients suffering a hemorrhage or cardiac arrest. Both hemorrhage and cardiac arrest re (Read more...)

Mobility-Enabled Compression Device for Lymphedema: Interview with CEO of Koya Medical

Koya Medical, a medtech company based in California, has developed the Dayspring active compression system for the treatment of lymphedema. The company received FDA clearance for the use of Dayspring on the upper extremities in June 2020, and just recently announced 510(k) clearance for use in the lower extremities. Lymphedema involves impaired lym (Read more...)

Kirigami Stent for Localized Drug Delivery

Researchers at MIT have developed a kirigami-style stent that can provide localized drug delivery through needle-like projections that pop out when the stent is extended. The ‘spines’ on the stent’s surface deliver drug-loaded microparticles into the surrounding tissue, allowing for sustained drug release for an extended period. T (Read more...)

Anti-Restenotic Drug Delivery with the AGENT Drug-Coated Balloon: Interview with Dr. Ian Meredith, Global CMO, Boston Scientific

Boston Scientific recently announced a clinical trial of its AGENT drug coated balloon. The device is coated with paclitaxel, an anti-restenotic drug, and aims to deliver the medication to the affected vessel wall during a percutaneous procedure. Coronary in-stent restenosis (ISR) is caused by occlusive scar tissue that develops in the stented port (Read more...)

PerQseal+ for Large Diameter Arterial Closure: Interview with Andrew Glass, CEO of Vivasure Medical

Vivasure Medical, a medtech company based in Galway, Ireland, has developed the PerQseal device, a synthetic implant designed to seal large bore blood vessel punctures. The implant has utility in a wide variety of transcatheter endovascular procedures, such as transcatheter aortic valve replacement (TAVR), thoracic endovascular aneurysm repair (TEV (Read more...)

Light-Responsive Hydrogel to Fill Cerebral Aneurysms

Researchers at Pohang University of Science & Technology (POSTECH) in Korea have developed a new technique to treat cerebral aneurysms. Described in journal Advanced Materials, the treatment involves using a catheter to deliver an alignate hydrogel that is crosslinked in place within the aneurysm using light. The hydrogel is not degradable and (Read more...)

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...)

Rapid Compression Device to Prevent Deep Vein Thrombosis

Researchers at Penn Medicine have developed a wearable sleeve that provides rapid pulsatile compression, and aims to mimic the compression our calf muscles experience during walking. The technology, being commercialized by Osciflex, a spin out from Penn Medicine, is intended to prevent deep vein thrombosis in patients who are bed-bound for long per (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...)

Micro-Aneurysm-On-A-Chip to Model Vascular Disease

An international research collaboration, including teams from Nanyang Technological University, Singapore (NTU Singapore), Brown University, and MIT, has developed an AI platform that can assess blood flow characteristics through microvasculature. The system relies on a microfluidic chip that mimics vascular disease, in this case a micro-aneurysm i (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.
