Catheter News and Research

RSS

In medicine, a catheter is a tube that can be inserted into a body cavity, duct, or vessel. Catheters . In most uses, a catheter is a thin, flexible tube ("soft" catheter), though in some uses, it is a larger, solid ("hard") catheter. A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter. A permanently inserted catheter may be referred to as a permcath.

Stretchable catheter could help identify high-risk arterial plaque

We all know about plaque from dreaded trips to the dentist. But plaque can also build up inside the arteries, taking the form of fatty deposits that can potentially restrict blood flow.

Healthcare barriers impact survival rates for adult congenital heart disease

People with congenital heart disease living in states with low household incomes and limited access to health insurance and the specialized care they need may be more likely to become disabled or die from congenital heart disease, according to new, independent research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Study reports a counterintuitive new approach to treating mesothelioma

Mesothelioma is a rare but aggressive cancer, usually caused by exposure to asbestos. Inhaled asbestos fibers become lodged in the lungs, causing inflammation that can lead to tumor formation decades later. Worldwide, about 30,000 people are diagnosed with mesothelioma each year.

Nerve stimulation methods provide safe relief for oropharyngeal dysphagia

Dysphagia, a severe comorbidity of many neurological diseases, often lacks targeted therapies. This critical review assessed the clinical effectiveness and safety of electrical stimulation of cranial nerves for treating dysphagia, including implantable (direct nerve stimulation), minimally invasive (pharyngeal electrical stimulation, PES), and non‑invasive (transcutaneous) approaches.

Micro and nanorobots could transform blood clot treatment

Newer tethered devices address some of these limitations: the "milli‑spinner" thrombectomy device applies compressive and shear loading to compact a clot to about 10% of its original volume, enabling ultrafast removal even in pulmonary and cerebral arteries (in vitro and porcine studies).
