Allergan gel-based stents are treating glaucoma

An Allergan-developed gelatin-based stent is showing potential to treat glaucoma in a quicker and safer environment, according to new research from the University of Michigan. Glaucoma is a disease that damages the eye’s optic nerve and can cause vision loss and blindness. Medicines in the form of eyedrops or pills can be used to treat

Amaranth Medical looks to recapture the potential of bioresorbable scaffolds

Dr. Antonio Colombo had finished his presentation of 9-month data for Amaranth Medical‘s Aptitude sirolimus-eluting bioresorbable scaffold when an audience member asked about adverse events. He told the EuroPCR attendee that they hadn’t seen any adverse events related to the device during the trial – and that’s unusual. Bioresorbable scaffolds, like Abbott‘s (NYSE:ABT) Absorb, have been

How Boston Sci is getting drug-eluting stents and balloons into legs

Boston Scientific officials think they have a leg up when it comes to bringing drug-eluting technology to bear on peripheral artery disease. That’s because the medical device giant has decades of experience with balloons and drug-eluting stents used around the heart. When it comes to treating the narrowing arteries in the legs and thighs, Boston

Supremes remand medtech patent cases

The U.S. Supreme Court sent back several appeals to the federal circuit this week, including 1 relating to Johnson & Johnson‘s (NYSE:JNJ) stent patent fight with Medinol, in light of a recent vote regarding the use of laches in patent infringement cases. Defendants use laches to declare that a plaintiff unreasonably delayed in bringing a claim

Medtronic: Certain stent grafts may confuse during implantation

Some Endurant and Endurant II bifurcated stent graft systems could fool doctors into thinking a more serious endoleak is taking place during the implant procedure, causing the doctors to take unnecessary extra interventions, Medtronic is warning in a letter to health providers published in Europe. The voluntary recall announcement, posted today on the website of

For malignant biliary obstruction, plastic stents may be cost-effective alternative

Preoperative biliary drainage (PBD) with stent placement has been commonly used for patients with malignant biliary obstruction. In PBD, the placement of fully covered self-expandable metal stents (FCSEMSs) may provide better patency duration and a lower incidence of cholangitis compared with plastic stents. But a new study suggests that plastic stents may provide similar outcomes

3D printing strong, flexible, biodegradable stents

Vascular stents typically come in a number of different lengths and diameters. The physician implanting the device chooses the best fit for individual patients, but often the available sizes are not ideal. To address this need, researchers at Northwestern University turned to 3D printing to create stents of any size that are customized to each patient’s unique

Cleveland Clinic unveils its picks for the medical innovations most likely to be game changers

Smart cars that reduce accidents and injuries. Immunotherapy that helps kids beat cancer without chemo. Stents that harmlessly dissolve when their work is done. These are some of the innovations that will enhance healing and change healthcare in the coming year, according to a distinguished panel of doctors and researchers. Cleveland Clinic today announced the

Exploring encapsulated ePTFE

Expanded polytetrafluoroethylene (ePTFE) is a flexible, biocompatible material, used to cover stents and stent grafts. The lubricity, strength, and durability of the material makes it valuable during stent deployment and in situ. But as the manufacturing processes for it have improved, it is seeing renewed interest in other vascular applications, including transcatheter heart valves. Material

NuMed CP stent: B. Braun extends deal

B. Braun Interventional Systems said today it extended its exclusive U.S. distribution deal with NuMed for to include its newly-cleared Cheatham Platinum stent designed to treat native or recurrent coarctation of the aorta. The CP stent won FDA 510(k) clearance in March, and the commercial launch in the U.S. is scheduled to take place this week,

Stenting will continue to be a viable alternative to surgery in carotid artery stenosis, says GlobalData Analyst

Recent results from a trial known as the Carotid Revascularization Endarterectomy versus Stenting Trial (CREST), showing that patients with severe carotid artery stenosis suffered similar rates of adverse events in both stenting and endarterectomy procedures, are evidence that stenting will continue to remain competitive with surgical treatment, says an analyst with research and consulting firm

Cardiologists use 3D printing to personalize treatment for heart disease

University of Melbourne doctors and engineers are using supercomputers to create 3D models from patients with heart disease, with photos from a camera thinner than a human hair. The images, gathered during a routine angiogram, are fed into a supercomputer. Within 24 hours, a model of a person’s artery is 3D printed. This gives cardiologists

What is a stent?

A stent is a wire mesh tube intended to prop open an artery. When made from stainless steel or nickel-titanium (nitinol), stents are intended to be permanent. More recent stents are made of polymers designed to dissolve over a period of months. Fatty deposits called plaque can build up in an artery and reduce the

Simulating the release mechanism in drug-eluting stents

Simulations of drug-eluting stents by engineers at Boston Scientific provide an understanding of the drug-release mechanism by tying experimental findings to a computational model. Lexi Carver, Comsol, Inc Contributing authors: Travis Schauer and Ismail Guler, Boston Scientific Corp Treating arteries in the heart that have been blocked by plaque is a common challenge for medical
