Also in August, Boston Scientific shared the news of the acquisition of Obsidio, a privately held company that has developed the Gel Embolic Material (GEM) technology used for embolization of blood vessels in the peripheral vasculature.


3) EuroPCR 2022: Studies underscore potential of renal denervation as an adjunctive therapy for hypertension

Late-breaking trial data presented at EuroPCR 2022 (17–20 May, Paris, France) underscored the potential of renal denervation as an adjunctive therapy to treat hypertension, complementing existing first-line treatments including lifestyle modifications and medication, attendees of the conference heard.


4) “Promising” 10-year findings on PAE for BPH presented at ET 2022

Tiago Bilhim (Saint Louis Hospital, Lisbon, Portugal) presented during the Scientific Paper session at this year’s European Conference on Embolotherapy (22–25 June, Nice, France), and won the award of best abstract for his and co-authors’ ‘Long-term outcome of prostatic artery embolization for patients with benign prostatic hyperplasia’.


5) BD launches first-in-human trial of a peripheral sirolimus drug-coated balloon

Again in August, BD announced the start of enrolment in the PREVISION first-in-human trial, a prospective, multicentre, single arm, non-randomised study designed to evaluate the safety of the BD sirolimus DCB in the treatment of peripheral arterial disease (PAD) in the femoropopliteal arteries.


6) Otsuka Medical Devices and ReCor Medical submit pre-market approval of Paradise ultrasound renal denervation system

In November, Otsuka Medical Devices and ReCor Medical, a subsidiary of Otsuka, shared the news that they had filed a pre-market approval (PMA) application to the US Food and Drug Administration (FDA) for the Paradise ultrasound renal denervation (uRDN) system in the treatment of uncontrolled hypertension.


7) Bentley acquires GoBack catheter from Upstream Peripheral Medical Technologies

Bentley announced in September that it had acquired the rights of the GoBack catheter from Upstream Peripheral Technologies.


8) Medtronic receives CE mark for first balloon-expandable covered stent for ChEVAR

September also saw Medtronic share that it received CE mark for its Radiant balloon-expandable covered stent, the first and currently, only, covered stent indicated for use in chimney endovascular aneurysm repair (ChEVAR) with the Endurant II/IIs stent graft system.

10) For some small kidney cancers, freezing is more effective than heat

For patients with early-stage renal cell carcinomas (RCCs) that measure between 3 and 4cm, cryoablation yields a lower risk of cancer-related death compared to thermal ablation, reports a preliminary study in the Journal of Urology published in November.
