ChronoFlex* Polyurethane Catheters
ChronoFlex* polyurethane catheters have been proven to exhibit superior biodurability compared with other polyurethane catheters, making them ideal for long-term, blood-contacting devices. In vivo studies indicate the ChronoFlex* polyurethane catheter has less propensity for surface biodegradation, making it more resistant to environmental stress cracking.
- Given the inherent material strength of ChronoFlex* polyurethane, it is superior to Tecoflex* urethane for use with Taxol* or Taxotere* drugs.
- Firmness and rounded tip facilitate advancement into vein.
- Thin catheter walls offer increased flow-rate capabilities.
- ChronoFlex* polyurethane catheters are exclusive to Bard Access Systems’ implanted ports.
The three-way Groshong* valve allows infusion and blood aspiration while reducing the risk of air embolism, blood reflux and clotting. Flushing frequency is decreased because the valve prevents blood from backing into the catheter and clotting. Because the system is closed, routine maintenance is simplified and the need for heparin is eliminated.
- Negative pressure opens valve inward, permitting blood aspiration.
- Positive pressure opens valve outward, allowing infusion.
- At neutral pressure, valve remains closed, reducing risk of air embolism, blood reflux and clotting.
Open-Ended Silicone Catheters
Bard Access Systems’ open-ended central venous catheters continue to set the standard for performance and reliability.
- Soft, atraumatic tip offers added safety during implantation.
- Medical-grade radiopaque silicone construction ensures biocompatibility.
- Available in attachable and pre-attached configurations.
