Data Overview

 

HydroMID® Study Analysis* 

In a retrospective clinical study of 205 patients:

  • The HydroMID® showed a statistically significant reduction in failure rates and 6X fewer complications than standard polyurethane. 

  • The HydroMID catheters demonstrated no DVTs versus 7% DVTs with the standard polyurethane catheters.

  • Taking into account all of the complication costs, the polyurethane catheters incurred an estimated $175,000+ in additional costs for complications with 7 DVTs and 22 device replacements versus the HydroMID devices.**

HydroPICC® Study Details

In a retrospective clinical study of 121 patients:

  • The HydroPICC demonstrated no occlusions or replacements compared to 13 occlusions and 8 replacements with the standard polyurethane catheter.

  • Using HydroPICC resulted in a potential savings of up to 50% in additional material costs versus the standard polyurethane catheter highlighting the potential for time and cost savings with this device.

Results of a Bench Model Investigation Bacterial Adhesion

  • The purpose of this study was to compare bacterial adhesion on catheter samples using in-vitro blood flow and static models.

  • Fresh heparinized bovine blood was radiolabeled, and bacteria (Staphylococcus Aureus) was introduced.

    TPU, Fluoro-modified TPU and HBM catheters were inserted into tubing segments

    At the end of the flow phase, the catheters were explanted from the tubing and incubated in vials.

    After the 4-hour incubation phase, the thrombus/bacteria were stripped from each catheter, processed and plated to measure the number of bacteria and thrombus present on each catheter.

    A total of 12 replications was completed.

  • Conclusion

    The data presented demonstrates a strong correlation between relative thrombogenicity and reduced bacterial adhesion of the HBM compared to traditional polyurethane devices.

Reduction of thrombus accumulation was evaluated using in vitro models. Pre-clinical in vitro valuations do not necessarily predict clinical performance with respect to thrombus formation.

Three 4 Fr PICC devices that were evaluated in the in vitro trackability and pushability test.

  • HydroPICC® reduced the average tracking force vs a standard polyurethane catheter by 84%.

  • HydroPICC reduced the average tracking force vs a thromboresistant polyurethane catheter by 90%.
