Viper ULTRA trombolysekateter

Viper ULTRA trombolysekateter

En ultra infusionskateter specialiseret til direkte trombolytisk levering, med multi-hul design til ensartet fordeling af lægemidler på tværs af store blodpropsegmenter.

Information

Den Viper® Ultrasonic Pharmacomechanical Thrombolysis System er en minimalt invasiv device designed to dissolve thrombi by combining targeted ultrasonic waves with controlled tPA infusion. By thinning fibrin og increasing clot porosity, the system enables deeper drug penetration into the thrombus, thereby enhancing the efficacy of pharmacological therapy. This approach helps mitigate potential bleeding complications og preserves vessel integrity, offering a more refined, patient-centric strategy for acute thrombosis management.

Ultrasonic Wave Delivery
  • Controlled Ultrasound: Low-power ultrasonic energy focuses on fibrin disruption, loosening the structural integrity of the clot.
  • Enhanced Porosity: Breaking fibrin strands encourages tPA to penetrate deeper, ensuring thorough thrombus dissolution.
  • tPA Administration: A site-specific delivery of tissue plasminogen activator (tPA) directly into the clot.
  • Synergistic Effect: Ultrasonic micro-cavitation augments the fibrinolytic effect, requiring lower drug doses and potentially reducing hemorrhagic complications.
  • Minimal Vessel Trauma: Ultrasonic waves are calibrated to avoid damaging valves, vessel walls, or critical structures within the venous or pulmonary vasculature.
  • Reduced Bleeding Risk: Lower overall drug usage and localized infusion can curtail systemic side effects.
