VasSol touts data on MRI-based blood flow measurement
VasSol said last week that results from a trial of its Nova non-invasive optimal vessel analysis showed that the device was able to identify critical trial patients at higher risk of recurrent stroke. The results from the study were published in the JAMA Neurology journal.
Results from the 6-year, multi-center Veritas trial indicated that patients who experience a stroke in the back of their brain, and continue to have reduced blood flow to the area, have a higher risk of having another stroke within 2 years.
“Nova is the only technology that can visualize and quantify the volume, speed and direction of blood flow...

MassDevice Q & A: Claret Medical ’ s Azin Parhizgar on trying to make TAVR safer
Cerebral protection developer Claret Medical recently won FDA de novo clearance for its Sentinel device designed to trap blood clots and prevent stroke during heart valve replacement procedures.
The Sentinel uses a pair of filters, 1 in the brachiocephalic artery another in the left common carotid artery, to trap debris released during transcatheter aortic valve replacement that could cause a cerebral embolism.
The device has seen a rough road to approval, however, after missing the primary efficacy endpoint in its pivotal trial. Despite that, the device saw nearly unanimous support from an FDA advisory panel and was c...

J & J ’ s Cerenovus launches Galaxy G3 mini embolic coil, touts Arise II Embotrap study data
Johnson & Johnson‘s (NYSE:JNJ) Cerenovus division this week announced the launch of its Galaxy G3 Mini embolic coil and released data from a study of its Embotrap device designed to remove clots from the brain following ischemic stroke.
The Galaxy G3 Mini coils are designed to be approximately 25% softer than the Galaxy G3 xsft coils, with an ultra-low coil profile and a primary wind diameter of 0.009 inches, which Cerenovus said is the lowest profile available in its Spectra line.
The newly launched coil is designed to have a random complex shape to make it comformable and enable the device to seek and fill open...

Stryker wins expanded FDA indications for Trevo thrombectomy device
Stryker (NYSE:SYK) said today it won expanded FDA indications for its Trevo thrombectomy device, now cleared as a front-line treatment for acute ischemic stroke patients for up to 24 hours from symptom onset.
The expanded indication lifts the previously cleared treatment window by 18 hours, according to the Kalamazoo, Mich.-based company.
“The 24-hour indication opens the treatment window to patients whose stroke would previously have progressed until all the brain tissue surrounding the affected arteries was dead, leaving them with a life of significant disabilities. These patients now have a much better chance for...

Stryker touts NEJM publication of Trevo thrombectomy device trial results
Stryker (NYSE:SYK) yesterday released results from the Dawn trial of its Trevo thrombectomy device, touting significant effects even when used beyond six hours after stroke.
Results from the trial were published in the New England Journal of Medicine, the Kalamazoo, Mich.-based company said.
“By quadrupling the size of the therapeutic time window, the consequence of Dawn is that many more patients with large vessel occlusion stroke have the potential to be treated with mechanical thrombectomy. Dawn validates the physiological, rather than time-based approach to patient selection for endovascular therapy,” co...

Gore wins expanded indications for Cardioform septal occluder
W.L. Gore & Associates said today it won expanded FDA indications for its Cardioform septal occluder, now cleared for the closure of patent foramen ovale to reduce the risk of recurrent ischemic stroke in certain patients.
The expanded application was supported by results from the Reduce study, which the Newark, Del.-based company said showed that closure of PFOs could significantly prevent recurrent ischemic stroke regardless of PFO anatomy.
“With the FDA approval of the Gore Cardioform septal occluder for PFO closure, we can now provide physicians with one device that can be used for both ASDs and PFOs. The val...

Report: Extra insights, but no clear-cut answers from TAVR embolic protection studies
Data from two new studies has provided extra insights, but no clear-cut solution for predicting stroke and which patients should receive embolic protection devices during transcatheter aortic valve replacement procedures, according to a new Medscape report.
Results from a meta-analysis of 1,285 patients indicated that the use of embolic protection devices during TAVR procedures did not reduce mortality, but was associated with a lowered rate of stroke at 30 days, according to the report.
The decline was mainly driven by registry data and was not confirmed by randomized controlled trials, Medscape specified.
Stroke was repo...

St. Jude wins FDA nod for Amplatzer PFO occluder
St. Jude Medical (NYSE:STJ) today won FDA approval for its Amplatzer patent foramen ovale occluder device, designed to reduce the risk of stroke in patients who’ve experienced a PFO-related stroke.
Approximately 25-30% of Americans have a PFO, according to the FDA, which typically causes no health problems and does not require treatment. While the cause of most strokes can generally be identified, some patients experience strokes which cannot be medically identified, known as cryptogenic stroke.
A small percentage of cryptogenic strokes are believed to be caused by PFOs, which provide a path for a blood clot to trav...

Medtronic touts Solitaire stent retriever data
Medtronic (NYSE:MDT) yesterday touted data presented at the International Stroke Conference on its Solitaire stent retriever from 4 studies. The Solitaire stent retriever uses a micro-sized catheter to access arteries in the brain, restoring blood flow and removing blood clots that cause acute ischemic stroke.
The Stratis AIS study evaluated the impact of treatment delays and patient outcomes when patients were treated with the Solitaire stent retriever and intravenous tissue plasminogen activator. Of the 984 enrolled patients, 64% were treated with the device and IV-tPA, while 36% were treated with the stent retriever al...
