SILK Flow-Diverting Device for Intracranial Aneurysms

World Neurosurgery, 2011
The SILK intracranial stent is a Conformité Européenne mark-approved endovascular device. This flow-diversion device is being used in Europe for intracranial aneurysm treatment by aneurysm occlusion. The device construct creates an intracranial bypass conduit that reconstructs the parent vessel while maintaining patency of the perforating arteries and ...

Re Multi Fracturing with Flow Diverter

SPE Symposium: Hydraulic Fracturing in Russia. Experience and Prospects, 2020
Summary As of today, there are various methods of repeated multistage fracturing. Mostly, they are associated with the involvement of coil tubing and well workover services. These are assemblies with opening and closing frac sleeves, small-sized packers, twin packers, CT packers… All the methods are extremely costly in economic terms ...

Aneurysm Treatment with Flow Diverters

2018
Flow diversion is a novel treatment for brain aneurysms that works by redirecting blood flow away from the aneurysm. By placing a stent in the parent vessel that covers more of the opening to the aneurysm with mesh than traditional stents, blood flow is redirected away from entering the aneurysm.

Delayed Posttreatment Residual Flow into Aneurysm After Flow Diverter Placement

World Neurosurgery, 2018
Inflow into an aneurysm sac immediately following flow diverter (FD) treatment is an assumed cause of delayed aneurysmal rupture. The significance of delayed posttreatment residual flow occurring months after FD treatment is unknown.A 76-year-old woman with a large intracranial aneurysm measuring 23.0 × 18.1 mm in the cavernous segment of the right ...

Hemodynamic Performance of Oversized Flow Diverters

ASME 2011 Summer Bioengineering Conference, Parts A and B, 2011
Although endosaccular coiling of aneurysms has been shown to be effective and has arguably replaced surgery for the treatment of most aneurysms it has significant limitations in achieving durable occlusion of many large and giant aneurysms because of a propensity for recanalization. For this reason flow diverting stents are increasingly been considered

Development of a Smart Flow Diverter

SPE Bergen One Day Seminar, 2014
Abstract In liner drilling operations the annular velocity of the drilling fluid drops significantly when it transits from the narrow cross section of the openhole-liner annulus into the increased annular volume between the casing and the drillpipe above the liner.

Computational flow dynamics of a novel next-generation flow diverter

Journal of NeuroInterventional Surgery
BackgroundFlow-diverting stents (FDS) have revolutionized the treatment of large, giant, and wide-neck intracranial aneurysms. FDS promote thrombosis and aneurysm occlusion by redirecting blood flow within the parent artery. This method of endovascular therapy has proven efficacious, although leaving room for improvement.
