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.

AI-based model predicts glioblastoma recurrence to guide targeted treatment

A new AI-based model can predict where glioblastoma is most likely to return after initial surgery, potentially giving doctors a chance to treat it before it becomes visible on MRI.

The FFS (Fight Fibrin Sheath) campaign launches to improve patient lives by tackling dialysis catheters' most common dysfunction

An international coalition of vascular access surgeons, nephrologists, researchers and industry partners today launched the Fight Fibrin Sheath (FFS) campaign, a clinician-led action group working collaboratively to advance research, education and innovation relating to fibrin sheath formation, and to improve vascular access outcomes for dialysis patients worldwide.

Stevia tastes sweet, but does your body react as if sugar is coming?

In a randomized, double-blind crossover study, researchers tested stevia alone and with glucose in adults with normal weight, overweight, or type 2 diabetes to assess acute effects on blood glucose, insulin, gut hormones, appetite, and subsequent food intake. Stevia produced no significant changes in the measured glycemic or hormonal responses compared with water and did not significantly modify responses to glucose, while appetite and subsequent energy intake were also generally unchanged.

Catheter-directed thrombolysis improves short-term outcomes in pulmonary embolism patients

In patients with intermediate−high risk pulmonary embolism, catheter-directed thrombolysis improved short-term clinical outcomes compared with standard anticoagulation therapy alone, according to results presented in a Hot Line session today at ESC Congress 2026.

Older heart attack patients need routine invasive treatment rather than selective care

A routine invasive approach should not be replaced with a more selective approach in older patients with the most common type of heart attack.

Catheter ablation reduces AF recurrence but not quality of life

Catheter ablation for atrial fibrillation (AF) did not significantly improve AF-related quality of life compared with a sham procedure, despite reducing AF recurrence.

New battery-free pacemaker harvests power from every heartbeat

A team of University of Wisconsin–Madison researchers has developed an implantable, battery-free pacemaker that's charged by a patient's heartbeat.

Wearable sensors coupled with AI can non-invasively monitor blood pressure

Wearable sensors coupled with AI can generate blood pressure readings nearly as well as the invasive and risky arterial lines relied on in intensive care units and operating rooms, new work by Johns Hopkins University researchers demonstrates.

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.

Experts call for better trials as IVF preparation techniques show unproven results

Preparation techniques used before embryo transfer, considered the most critical step in the IVF process, show no proven effect on pregnancy rates and remain inconclusive due to limited or low-quality data, a new Cochrane review finds.

Experimental neurointerventional technique shows promise for severe back pain

Researchers at the Society of NeuroInterventional Surgery (SNIS) 23rd Annual Meeting presented an experimental neurointerventional technique designed to treat severe back pain, a leading cause of disability and opioid use, by delivering medication directly through the arteries supplying the painful area.

AI-guided technique improves targeted therapy delivery for brain tumors

Researchers presented a groundbreaking artificial intelligence (AI)-guided technique today at the Society of NeuroInterventional Surgery's (SNIS) 23rd Annual Meeting that may improve the accuracy of delivering experimental therapies directly to malignant brain tumors.

Researchers identify risk factors for postoperative cerebral ischemia in patients with moyamoya disease

The buildup of fats, cholesterol, calcium, and immune cells within the blood vessel can lead to the narrowing or even complete blockage of the blood vessel.

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.

New soft robotic heart accurately mimics the complex movements of human valves

Researchers at UNSW Sydney have developed a fully synthetic soft robotic heart that reproduces the complex movements and internal structures of the human heart, opening the door to better treatments, safer medical devices and more personalized care.

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.
