Svelte Medical Systems Announces Sustained Outstanding Outcomes in Clinical Studies

First-in-Man Study Using the World’s First Drug-Eluting Stent-on-a-Wire Completes 5-Year follow-up with 0% Major Adverse Cardiac Events; No Additional Revascularizations through 3 Years in DIRECT II Study


Final 5-year outcomes from the DIRECT first-in-man study were presented at the EuroPCR symposium today, with 0% clinically-driven Target Lesion Revascularization (TLR), Target Vessel Failure (TVF) and Major Adverse Cardiac Events (MACE) reported. The DIRECT single-arm study enrolled 30 patients at 4 centers in New Zealand to assess the feasibility of the Svelte drug-eluting coronary stent-on-a-wire Integrated Delivery System (IDS) in patients undergoing percutaneous coronary intervention.

“Longer-term follow-up of novel coronary stents is very important, as shown by the recent findings of unexpectedly high rates of very late thrombosis in bioresorbable scaffolds. The absence of late adverse clinical events through 5 years is unusual in any stent study. Considering half of the lesions treated in DIRECT were type B2/C and 97% device success was achieved despite all investigators being first-time operators with the system, I am very impressed with these results,” said Mark Webster, interventional cardiologist at Auckland City Hospital and Principal Investigator of the DIRECT study.

Positive outcomes were also reported in the DIRECT II study through 3 years. In patients treated with the Svelte IDS, 3-year MACE remained unchanged from 1 year at 3.7%, while in the control arm, MACE increased from 7.8% to 9.8%. Neither arm had reports of stent thrombosis through 3 years.

DIRECT II is a prospective, randomized, multi-center clinical study comparing the safety and efficacy of the Svelte IDS with the Medtronic Resolute Integrity™ drug-eluting coronary stent in 159 patients. Direct stenting was performed in approximately 90% of lesions. Though powered only to demonstrate non-inferiority in 6-month angiographic outcomes between both arms, the DIRECT II study continues to demonstrate numerical superiority of the Svelte IDS arm compared with the control arm in all clinical outcomes through 3-years. The Svelte arm further exhibited reduced procedure and device times, with trends toward reduced fluoroscopy time and contrast use compared with the control arm, confirming results observed in prior studies utilizing the Svelte IDS.

“The long-term results observed in the DIRECT and DIRECT II studies, coupled with no reports of stent thrombosis now through 5-years, indicate our technologies provide excellent and sustained patient outcomes,” said Jack Darby, President and CEO of Svelte Medical Systems. “Our unique approach to stent delivery and bio-friendly drug coating allow physicians to streamline PCI and achieve best-in-class results, delivering both clinical and economic value to the healthcare system. We look forward to serving more patients and physicians around the globe.”

Svelte is working with the FDA and PMDA to obtain regulatory approvals for clinical evaluations of its DES technologies in the US and Japan, and plans to initiate a clinical study during the second half of 2017. The IDS, incorporating Asahi ACT ONE™ wire technology and a proprietary low-compliant delivery balloon, is commercially available in select accounts in Europe as SLENDER IDS. Svelte has additionally developed a rapid-exchange system (DIRECT RX) using the same proprietary DES and balloon technologies, which attained CE Mark certification last year.

Samsung’s phone-as-desktop concept now runs Linux

Samsung's DeX is a clever way to turn your phone into a desktop computer. However, there's one overriding problem: you probably don't have a good reason to use it instead of a PC. And Samsung is trying to fix that. It's unveiling Linux on Galaxy, an app-based offering that (surprise) lets you run Linux distributions on your phone. Ostensibly, it's aimed at developers who want to bring their work environment with them wherever they go. You could dock at a remote office knowing that your setup will be the same as usual.

It's not quite the same as your typical Ubuntu or Debian install. Linux on Galaxy launches through an app, and it's using the same kernel as Android itself in order to maintain performance. And it almost goes without saying that you'll really want a DeX setup, since most Linux apps are expecting a large screen, mouse and keyboard.

As it stands, you'll have to be patient. Linux on Galaxy isn't available right now -- you can sign up for alerts, but it's not ready for public consumption. Even so, this is good evidence that Samsung thinks of DeX as considerably more than a novelty feature. It may be a long, long while (if ever) before many people are using their phones as desktops, but Samsung is willing to gradually build up its ecosystem and eventually give you an incentive to take a second look.
