The tiny grabber that plucks blood clots out of a vein (The Mail on Sunday)
Thousands of patients suffering from deep vein thrombosis (DVT) are set to benefit from a lifesaving procedure using a new blood clot grabbing device pioneered by NHS specialists. The treatment involves inserting a stent, a tiny, ball- shaped wire cage into a blocked vein. Once in position, the collapsible cage is expanded and ‘ catches’ the clot. When the device is pulled out, the ...

Amplifi Vein Dilation System: A novel device under development designed to prepare veins for AVF creation
The Amplifi Vein Dilation System (Artio Medical) is is an innovative device designed to dilate arm veins in preparation for AVF surgery using rapid, non-pulsatile venous blood flow. Surendra Shenoy, M.D. (a vascular surgeon with specialist interest in vascular access and transplantation at Washington University School of Medicine, St Louis, Missouri, USA) describes the system as one of the most ...

Enzyme Therapy and Cancer
Two groups of experiments were conducted at the Michael Rees Hospital in Chicago. The experimental group is 21 to 31 years old, and the control group is 69 to 100 years old. Researchers found that the salivary amylase of young people is more than 30 times that of older people. This is why young people can easily digest sugar, bread, noodles, pastries, and cooked food. But these foods accelerate ...

Artio’s Amplifi System Treatment Before AVF Creation Studied in FIH Procedures
October 6, 2021—Surendra Shenoy, MD, presented findings from a first-in-human (FIH) evaluation of the Amplifi vein dilation system (Artio Medical, Inc.), which is a small, wearable blood pump device that dilates arm veins before arteriovenous fistula (AVF) creation. Amplifi is designed to improve AVF eligibility, reduce maturation failure, reduce time to maturation, and prolong primary ...

First-in-man demonstration of 18-month spatiotemporal stability of active atrial fibrillation source detected by Electrographic Flow mapping in persistent atrial fibrillation
Keywords: atrial fibrillation, catheter ablation, mapping, atrial fibrillation, source, electrographic flow Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue. The aim of this ...

LimFlow Percutaneous Deep Venous Arterialization
What interested you in LimFlow, and how did you get involved in the PROMISE I trial? Dr. Clair: Practicing vascular surgery, where a number of patients are evaluated for chronic limb-threatening ischemia (CLTI), you are guaranteed to have patients who are not candidates for percutaneous or surgical revascularization. These patients often have arterial systems open or identifiable to the ankle, ...

Velocity characteristics of atrial fibrillation sources determined by electrographic flow mapping before and after catheter ablation
Background: Electrographic-Flow-(EGF)-Mapping is a novel method to identify Atrial Fibrillation (AF) drivers. Sources of excitation during AF can be characterized and monitored. Objective: The aim of this study was to evaluate the correlation between velocity of EGF around a respective AF source and its spatial variability (SV) and stability (SST). Methods: 25 patients with AF were included in ...

Identification of active atrial fibrillation sources and their discrimination from passive rotors using electrographical flow mapping
Barbara Bellmann 1, Tina Lin 2, Peter Ruppersberg 3, Marit Zettwitz 1, Selma Guttmann 1, Verena Tscholl 1, Patrick Nagel 1, Mattias Roser 1, Ulf Landmesser 2, Andreas Rillig 4 Background: The optimal ablation approach for the treatment of persistent atrial fibrillation (AF) is still under debate; however, the identification and elimination of AF sources is thought to play a key role. Currently ...
