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 ...

Chocolate PTCA Balloon Catheter for pre-dilatation of an occluded right coronary artery - Case Study
Incomplete stent expansion and malapposed stent struts are a predictor of subacute and late stent thrombosis. Appropriate lesion preparation prior to stent implantation is necessary to assure complete stent expansion and stent strut apposition. This is of particular importance in challenging lesions, in particular those with calcific plaque. The goal of the pre-dilatation is to obtain optimal ...

Chocolate PTCA Balloon Catheter for pre-dilatation of an occluded circumflex and second obtuse marginal arteries - Case Study
Incomplete stent expansion and malapposed stent struts are a predictor of subacute and late stent thrombosis. Appropriate lesion preparation prior to stent implantation is necessary to assure complete stent expansion and stent strut apposition. This is of particular importance in challenging lesions, in particular those with calcific plaque. The goal of the pre-dilatation is to obtain optimal ...

Clinical implementation of the Humacyte human acellular vessel: Implications for military and civilian trauma care
ABSTRACT: The incidence of wartime vascular injury has increased and is a leading cause of mortality and morbidity. While ligation remains an option, current resuscitation and damage control techniques have resulted in vascular repair being pursued in more than half of wartime injuries. Options for vascular reconstruction are currently limited to autologous vein or synthetic conduits, choices ...

Susceptibility of ePTFE vascular grafts and bioengineered human acellular vessels to infection
Background: Synthetic expanded polytetrafluorethylene (ePTFE) grafts are routinely used for vascular repair and reconstruction but prone to sustained bacterial infections. Investigational bioengineered human acellular vessels (HAVs) have shown clinical success and may confer lower susceptibility to infection. Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial ...

Five Year Outcomes in Patients with End Stage Renal Disease Who Received a Bioengineered Human Acellular Vessel for Dialysis Access
Objective: Patients with end stage renal failure who require haemodialysis suffer morbidity and mortality due to vascular access. Bioengineered human acellular vessels (HAVs) may provide a haemodialysis access option with fewer complications than other grafts. In a prospective phase II trial from 2012 to 2014 (NCT01744418), HAVs were implanted into 40 haemodialysis patients at three sites in ...

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 ...

Cost-Effectiveness of Percutaneous Deep Vein Arterialization for Patients with No-Option Chronic Limb-Threatening Ischemia: an Exploratory Analysis Based on the PROMISE I Study
Abstract Background. As the most advanced stage of peripheral arterial disease (PAD), chronic limb-threatening ischemia (CLTI) is associated with a high risk of lower-limb loss and mortality. Percutaneous deep vein arterialization (pDVA) is a promising new treatment alternative for CLTI patients who cannot be treated with conventional revascularization techniques. Our study objective was to ...

Useful Information of Machined Tantalum
Tantalum was discovered by Swedish chemist A.G. Ekeberg in 1802, it is mainly present in tantalite and co-exists with niobium. Tantalum has moderate hardness and is full of ductility and can be drawn into filament thin foil. Tantalum has excellent chemical properties and very high corrosion resistance; it also has high melting point. Due to its excellent corrosion resistance, tantalum is widely ...

Costs Attributable to Arteriovenous Fistula and Arteriovenous Graft Placements in Hemodialysis Patients with Medicare coverage
Keywords Vascular access · Hemodialysis · Healthcare costs · Health economics · Arteriovenous fistula · Arteriovenous graft Abstract Introduction: Hemodialysis (HD) in end-stage renal disease (ESRD) patients requires vascular access (VA) through an arteriovenous fistula (AVF), a prosthetic arteriovenous graft (AVG), or a central venous catheter. While AVF or ...

Why auditing catheter dislodgement is a patient safety must
Chris Cheney at HealthLeaders Media released an article related to IV Catheter Dislodgement, the potential impact, and the need to audit these types of occurrences. The article focuses on Nancy Moureau’s work in understanding the impact of IV dislodgement, and ultimately a call to action: Records should be tracked with IV dislodgement reports as a mandatory effort, to continue to quantify ...

Arteriovenous Fistulae for Haemodialysis: A Systematic Review and Metaanalysis of Efficacy and Safety Outcomes
Background: Arteriovenous fistulae are the currently recommended gold standard vascular access modality for haemodialysis because of their prolonged patency, improved durability, and low risk of infection for those that mature. However, notable disadvantages are observed in terms of protracted maturation time, associated high rates of catheter use, and substantial abandonment rates. The aim of ...

Some results of studying laser micromachining at medical stents manufacturing
Cardio-vascular diseases are the number one killer in the world. As an alternative to common treatment methods the installation of specific-purpose stents into the damaged blood vessel could be used in order to minimise fatal outcomes. Existing technologies of stent manufacturing provide quite good results but are very expensive at the moment. The given paper deals with the design of stents for ...
