SIS Medical AG Welcomes the Results of the VICTORY Trial Demonstrating Non-inferiority of OPN NC to Intravascular Lithotrispy (IVL) for Lesion Preparation and Stent Expansion in Severely Calcified Lesions
5.11.2025 16:12:00 CET | Business Wire | Press Release
SIS Medical AG, a Swiss manufacturer of the Super-High-Pressure PTCA balloon catheter (OPN NC), is pleased to announce that the results of the investigator-initiated VICTORY trial were presented during the late-breaking clinical session at TCT 2025 by the Cardiovascular Research Foundation (CRF). The randomized, multi-center clinical study was designed to compare the safety and efficacy between the OPN and IVL devices for lesion preparation and optimized stent expansion in highly complex calcified coronary lesions, deploying a drug-eluting stent (DES). Coronary artery calcium affects approximately one-third of patients undergoing PCI and is a key contributor to procedural and stent failure.

"With a similar safety profile, OPN can be a feasible and faster alternative to IVL." Dr. M. Bossard, Senior Physician at Luzerner Kantonsspital, Switzerland
A total of 282 patients at three sites in Switzerland and Canada were randomized one-to-one to IVL (n=142) and OPN (n=140). The primary endpoint was final stent expansion assessed by optical coherence tomography (OCT) determined by an independent imaging core laboratory. The OPN group achieved a median of 85.0% stent expansion compared to 84.0% in the IVL group, meeting non-inferiority (95% CI: 82.5-87.5, p<0.0001). The use of OPN resulted in similar rates of acute procedural (98.6% versus 97.1%) and strategy success (98.6% for both) compared with IVL. The results were consistent across all patient subgroups.
Additionally, OPN was equally safe to the IVL device regarding in-hospital MACE, coronary artery dissections and perforations, or side branch occlusions. “This study clearly shows that utilizing an OPN NC is non-inferior to IVL for OCT-guided lesion preparation and stent expansion in severely calcified lesions,” said Matthias Bossard, MD, Head of CHIP & CTO-PCI Program at Luzerner Kantonsspital Heart Center. “With similar safety profiles, the OPN NC can be a feasible and faster alternative to IVL.”

TestMu AI Brings Real Device Testing to Kane CLI, Letting Developers Test Mobile Apps on Real Phones From Any Terminal16.10.2026 16:00:00 CEST | Press Release
TestMu AI (formerly LambdaTest), the Full Stack Agentic AI Quality Engineering platform, announced real device support in Kane CLI. Developers can now test a mobile app on a real phone or tablet in the TestMu AI cloud straight from the terminal: they type what to test in plain English, and Kane taps through the app on a real Android or iOS device. Until now, testing a mobile app on real hardware meant keeping a drawer of phones, or a separate device farm outside the developer's workflow. With real device support, Kane CLI removes that dependency again now by giving terminal-first access to the real device cloud. Kane CLI on real devices gives teams: Real Android and iOS devices from any terminal. Kane CLI opens a real device in the TestMu AI cloud and taps through the app from natural language prompts. Developers pick a model and OS version, or let the cloud assign any available device. A live view of the device. The real device's screen opens in its own window on the developer's lapto

Horizon3 and Pax8 Expand Partnership to Bring Autonomous Security Testing to MSPs Across Europe16.10.2026 08:03:00 CEST | Press Release
Horizon3, the AI-Native Proactive Security Company, today announced the expansion of its Pax8 partnership across Europe, bringing the NodeZero® Proactive Security Platform to the region’s managed service providers (MSPs) through the Pax8 Marketplace. The expansion enables partners to build recurring security services that help small and midsized businesses understand how attackers could compromise their environments, prioritize corrective actions, and verify remediation. Building on the companies’ North American marketplace launch, the European expansion makes autonomous offensive security testing accessible to more MSPs and the businesses they protect. Partners can use NodeZero to deliver initial assessments, support remediation engagements, and establish ongoing testing programs without conducting every penetration test manually. “MSPs are accountable for protecting their customers’ security, but a list of vulnerabilities does not tell them what is actually exploitable, and their lev
