Viper™ Valved Infusion Catheters

The Viper™ Valved Infusion Catheter is a single-lumen, valved-tip delivery system that offers the flexibility to infuse anti-thrombus agents, radiopaque contrast, or other physician-specified pharmacologic solutions with or without a guidewire in place.

The Viper™ Valved Infusion Catheter is a single-lumen, valved-tip delivery system that offers the flexibility to infuse anti-thrombus agents, radiopaque contrast, or other physician-specified pharmacologic solutions with or without a guidewire in place. By eliminating the need for a tip-occluding wire during treatment, Viper™ greatly expands the available infusion lumen, allowing higher flow rates and more efficient coverage of targeted vessel segments. Offered in 4F and 5F sizes and multiple lengths, Viper™ catheters are specifically intended for controlled and selective delivery of agents into the general vasculature—excluding coronary, pediatric, or neonatal applications.

Valved-Tip Construction
  • Flexible Infusion Options: The valve at the distal tip enables fluid infusion directly through the catheter lumen, even in the absence of a guidewire.
  • Improved Lumen Area: By avoiding a tip-occluding guidewire during treatment, the infusion pathway effectively doubles in diameter (compared to catheters requiring a wire in place), enhancing infusion capacity.
  • Large Infusion Lumen: Facilitates high-flow infusion of anti-thrombus agents or radiopaque contrast.
  • Enhanced Deliverability: Maintains a low-profile catheter body for streamlined advancement through tortuous vessels.
  • 4F & 5F Catheters: Address the needs of diverse peripheral vessel diameters—choose the size that best aligns with procedural goals.
  • Various Usable Lengths: Available in multiple lengths (consult device labeling) to accommodate short or extended lesion coverage and different access sites.
  • Adaptable: Suitable for physician-specified pharmacologic agents (e.g., thrombolytics, vasodilators) or routine contrast media.
  • Standard IFU Compliance: Pharmacologic agents should be prepared and administered per each drug’s instructions for use to ensure safe infusion.
