Electrospinning and 3D printing stent grafts to improve CVD surgery outcomes

A new 3D graft printing technique offers a potential solution to reduce thrombosis and restrain aneurysmal dilatation post-surgery, with potential for improving cardiovascular disease treatments.

Implantable smart stent monitors hemodynamics

Researchers at the Georgia Institute of Technology have developed a smart stent that can monitor hemodynamic parameters. The wireless and battery-free device can transmit the data to the outside of…

Stents can deliver drugs to the GI tract

Inspired by kirigami, the Japanese art of folding and cutting paper to create three-dimensional structures, MIT engineers and their collaborators have designed a new type of stent that could be used…

One step closer to regenerative heart valves and stents

Non-degradable prostheses for cardiovascular tissues can be used to replace heart valves and blood vessels, but they can’t stay in the body permanently. In two recent papers, researchers at the…

Introducing a thinner, stronger, more flexible iliac stent

Medical device company Biotronik is proud to announce the availability of its next-generation balloon-expandable cobalt chromium iliac stent system, Dynetic-35. When compared to leading competitors,…

An increasingly dynamic cardiovascular presence

In the world of laboratory diagnostics, ‘Abbott’ is a household name. Few people however are aware of the fact that the company, headquartered in Illinois, USA, is also leading in other fields. A…

Robotic angioplasty: The future of endovascular interventions

An exciting development from an innovative French company is poised for a major breakthrough in European markets. As is now well-known, coronary angioplasty is a procedure that widens and/or unblocks the arteries to the heart by the insertion and inflation of a balloon and/or stent into the vessel lumen. In modern practice, a stent is normally left in place to ensure the blood flow remains…

News • Microstents vs foetal urethral strictures

The world’s smallest stent

Researchers at ETH Zurich have developed a new method for producing malleable microstructures – for instance, vascular stents that are 40 times smaller than previously possible. In the future, such stents could be used to help to widen life-threatening constrictions of the urinary tract in foetuses in the womb. Approximately one in every thousand children develops a urethral stricture,…

Reversing blood flow reduces stroke risk during carotid artery procedure

Loyola Medicine is the first academic medical center in Illinois to use the TCAR system, which reduces stroke risk during carotid artery procedures by temporarily reversing blood flow. Carotid arteries on each side of the neck supply blood to the brain. In patients with carotid artery disease, a build-up of plaque can cause blockages. A common method to open the artery involves a balloon…

Saving Lives using new stent graft design

Vascular surgeon Pat Kelly of Sanford Health in Sioux Falls, South Dakota, knew his patients were doing better with the stent graft he designed, but he wanted a better understanding of the mechanics before testing the device more widely in a clinical trial. For that, he reached out to South Dakota State University. Associate professor Stephen Gent in mechanical engineering had done computational…

Endovascular thrombolysis

Neurologists keenly debate the value of mechanical reopening of blocked blood vessels in the brain, as demonstrated during the 21st World Congress for Neurology (WCN) in Vienna this September. Theoretically, endovascular thrombolysis can only be considered for 20-30% of all incidents of stroke.

Bioresorbable stents

Cardiologists believe they can restore coronary arteries thanks to a new generation of stents that help the body to strengthen collapsed vessels. Elsewhere, patients’ own stem cells are being programmed to rebuild cardiac muscle in HF patients.

Minimally invasive stents show some advantages over bypass

Compared to open bypass, stenting keeps circulation flowing longer in some patients, small study concludes.

The Symetis Acurate TA Aortic Bioprosthesis and delivery system

A new transcatheter aortic valve implantation (TAVI) system for transapical treatment of severe aortic stenosis – Acurate TA and delivery system –is a second- generation TAVI device to treat elderly patients. Launched by the Swiss firm Symetis SA, the system gained CE approval last September is on sale in Europe.

New generation drug-eluting stents

A registry -which includes every patient in Sweden having percutaneous coronary intervention (PCI) for the treatment of acute and stable coronary artery disease- has found that PCI implantations using a new generation of drug-eluting stents is associated with lower rates of relapse (restenosis), stent thrombosis and subsequent mortality than older generation drug-eluting stents and bare-metal…
