NeuroNews’ top 10 most popular stories of April 2022

157

Novel neurovascular technologies, from robotics, to microcatheters, to artificial intelligence (AI), were among the hottest topics featured on NeuroNews in April. A momentous company acquisition worth €500 million and an exclusive interview with Society of NeuroInterventional Surgery (SNIS) president Michael Chen also garnered plenty of attention throughout the month.

1. Why robotics holds the key to the future of stroke treatment

Vitor Pereira and Nicole Cancelliere (St Michael’s Hospital, Toronto, Canada) outline recent breakthroughs in the deployment of robotics for neurointerventional procedures and discuss future use indications for these technologies within stroke treatment.

2. Guidewire-less neurovascular navigation system shows promise in rabbit aneurysm model

A new concept for navigating the neurovasculature, performed without the aid of a guidewire, has demonstrated its ability to be manoeuvred through tortuous vessels, braided stents and occlusions, and to deliver and move coils, in preclinical investigations involving a rabbit aneurysm model. Details of the study, which utilised the Bendit 17 and Bendit 21 steerable microcatheters (Bendit Technologies), are published in the Journal of NeuroInterventional Surgery.

3. Wallaby acquires phenox to accelerate global expansion in neurovascular space

Wallaby Medical recently announced that it has acquired phenox GmbH—including phenox’s femtos GmbH—for a total consideration of approximately €500 million including milestone payments.

4. Study data indicate positive outcomes with “exciting new treatment option” in ischaemic stroke

Data from a multicentre clinical study supporting the use of Anaconda Biomed’s Advanced Neurovascular Access (ANA) catheter system for treating ischaemic stroke have been published in the journal Stroke.

5. Microvention announces enrolment of first patient in STRAIT study evaluating new balloon guide catheter

Microvention, a wholly owned subsidiary of Terumo Corporation, has announced the successful completion of its first patient enrolment in a multicentre, prospective, observational study called STRAIT.

6. Bendit receives FDA 510(k) clearance for 0.021-inch steerable microcatheter

Bendit Technologies has received US Food and Drug Administration (FDA) 510(k) clearance of its Bendit21 microcatheter for treatment in the neuro, peripheral and coronary vasculature.

7. PROFILE: Michael Chen

Michael Chen—a neurointerventionist and professor of Neurology, Neurosurgery and Radiology at Rush University Medical Center in Chicago, USA—speaks to NeuroNews to provide insight on his career, the ever-evolving world of neurointervention, and also his role in ongoing efforts to optimise USA-wide stroke triage and transport protocols as president of the SNIS.

8. Biomodex launches clear cartridges for neurovascular surgery training

Biomodex has announced the launch of new clear cartridges for use with all of its EVIAS (Endovascular intracranial aneurysm system) and EVIAS Plus stations for preprocedural 3D simulation.

9. Preliminary data indicate improved neurological outcomes with alteplase versus placebo

As per early findings from the CHOICE randomised controlled trial (RCT), the use of adjunct, intra-arterial alteplase—among patients with large vessel occlusion (LVO) acute ischaemic stroke and angiographically successful reperfusion following thrombectomy—may lead to a greater likelihood of an excellent neurological outcome at 90 days, as compared to a placebo.

10. Aidoc gains FDA 510(k) clearance for AI-supported triage and notification of brain aneurysm

Aidoc has received US Food and Drug Administration (FDA) 510(k) clearance for the triage and notification of brain aneurysm.
