Marvelous™ (MRVLS)

The first minimal residual volume luer-activated stopcock designed to save you time and increase safety. That’s why people ask for it by name. Marvelous™.

The Marvelous two main features both contribute to patient and caregiver safety and workflow improvement:

  • The luer-activated valve (LAV) serves as a bacterial barrier, allowing access to the line without opening it and producing a needle-free injection site.
  • The fluid flow around the handle creates a unique “circumferential channel” that reaches the entire internal volume of the valve. Whether a drug or blood, the internal volume is constantly flushed by the in-line flow providing greater protection against blood clotting and bacterial colonization.


Marvelous improves patient safety

The luer activated valve creates a bacterial barrier that reduces the risk of air embolism and contamination due to air and bacterial ingress.
The inner channel and the constant flushing of the side port minimize dead space and prevent stagnation, which, based on the results of several studies1-2, can reduce the risk of bacterial colonization

Fewer manipulations due to eliminating the need for syringe flush after IV bolus or blood sampling, further decrease the risk of nosocomial transmission of infection and also reduce medication errors.

Results from a Flushing study of Marvelous vs. other injection/sampling ports1

Blood residuals vs. flushing time (monitoring set with reservoir)No significant differences in blood residues were found between the three products

"Minimizing CLABSI is of great importance to us, and the study we conducted is just another important layer of the bundle we currently practice. The evidence demonstrates a statistically significant drop in stopcock (STP) colonization - when Marvelous is properly used"

Marvelous improves caregiver safety

The luer activated valve reduces the risk of needle stick injuries and decreases exposure to blood and drugs during stopcock manipulation.


Marvelous improves workflow

Eliminating post-medication/ blood sampling flushing with a syringe (including equipment preparation and disposal) saves approximately 1 minute per procedure. In the ICU, this may translate into 10 minutes per patient per day*.
* Depending on frequency of blood sampling or medication administration


Marvelous vs. other stopcocks

Conventional STP

Conventional STP with LAV

Priming Unscrew cap and remove air bubbles to ensure side port priming Use a syringe to manually purge air from add-on LAVs Carrier fluid automatically pushes the air out of the side port valve
Equipment saved by using Marvelous: Syringe (when priming a conventional STP with LAV)
Flushing – after medication administration/blood sampling Flush with a saline/prefilled syringe Swab the LAV with a Disinfectant wipe The internal volume of the valve is constantly flushed by the in-line flow
Recap with a sterile cap Flush with a saline/ prefilled syringe  
Equipment saved by using Marvelous: Flushing syringe, sterile cap, disinfectant wipe (for each procedure)

Marvelous improves work flow and reduces costs.
