Fresenius Medical Care North America Introduces First Single-Use Integrated Bloodline to Support Fluid Management in Dialysis

CombiSet SMARTECH™ Offers Innovative New Design and Simplifies Use

WALTHAM, Mass. – July 27, 2022 – Fresenius Medical Care North America’s (FMCNA) Renal Therapies Group today announced the availability of the CombiSet SMARTECHTM, the first available single-use bloodline with an integrated Crit-Line® blood chamber (CLiC™) that simplifies use by reducing the number of manual connections required. The CLICTM Blood Chamber is built into the bloodline itself and is designed to provide optimal performance with the 2008® series hemodialysis machines.

Crit-Line technology is designed to continuously monitor the percent change in blood volume, plasma refill, oxygen saturation and other key parameters during the hemodialysis treatment. This data can guide the clinician to intervene, if necessary, by adjusting the ultrafiltration rates to provide a more effective dialysis treatment. Fluid overload, or hypervolemia, is a common complication of kidney disease, particularly in patients with end-stage renal disease (ESRD) on hemodialysis. It is often associated with adverse outcomes including hypertension, exacerbation of congestive heart failure (CHF), and increased risk of death.1

“By combining these two components into one bloodline, we are simplifying the set-up process which will hopefully encourage increased use of Crit-Line technology,” said Dr. Mike Anger, SVP and Chief Medical Officer for FMCNA’s Renal Therapies Group. “This new bloodline is designed to make fluid management even easier, providing insights that can help better manage the fluid status of dialysis patients.”

The CombiSet SMARTECH offers key advantages when providing hemodialysis to patients in outpatient or acute settings:

  • Increased Ease of Use: Less product to manage at point of care; less inventory to maintain.
  • Fewer Connections: The new integrated bloodline line has only one connection, eliminating the need for additional components and simplifying the connection process.

“This introduction of this new bloodline is part of our commitment to bring innovations to market that improve patient care, making the dialysis process simpler and safer for our patients,” said Pat McCarthy, SVP of FMCNA’s Renal Therapies Group. “This new integrated system is a step forward within our already trusted and reliable bloodline product offerings.”

Indication for Use:
Crit-Line Technology is designed to non-invasively measure hematocrit, oxygen saturation and percent change in blood volume. The technology employs a sensor clip which emits multiple wavelengths of light to trans-illuminate the blood in the Crit-Line blood chamber.  The differences in light absorption between blood constituents allow for the identification and measurement of the hematocrit. The measurement of hematocrit, percent change in blood volume and oxygen saturation in real-time during hemodialysis is intended to provide a more effective treatment for both the dialysis patient and the clinician. Based on the data that the monitor provides, the clinician/nurse, under physician direction, can intervene (i.e., by increasing or decreasing the rate at which fluid is removed from the blood) to remove the maximum amount of fluid from the dialysis patient without the patient experiencing the common complications of dialysis which include nausea, cramping and vomiting. The technology is available as a stand-alone device (Crit-Line IV Monitor) or as an optional module on the 2008T hemodialysis machine series (CLiC™ device).
