MICROCUFF* Endotracheal Tubes

Revolutionary Cuff Technology: Proven to reduce leakage and the risk of tracheal trauma

MICROCUFF* Adult Endotracheal Tubes feature an advanced micro-thin polyurethane cuff, virtually eliminating the formation of channels typically found in PVC cuffs. This provides a superior tracheal seal proven to reduce leakage of potentially infectious secretions.1

MICROCUFF* Pediatric Endotracheal Tubes, designed specifically for the pediatric anatomy, offer the advantages of a cuffed tube, while reducing re-intubation rates and tracheal trauma.2

MICROCUFF* Subglottic Suctioning Endotracheal Tube

RINSE. SUCTION. CLEAR.

Combining more effective subglottic suctioning with our advanced BALLARD* polyurethane cuff technology, you can finally provide the BEST protection against microaspirtion. MICROCUFF* Subglottic Suctioning Endotracheal Tubes are proven to be more effective at preventing and clearing clogs. Now you no longer have to struggle to make subglottic suctioning actually work!5,7,8

Finally, a Clear Change to Subglottic Suctioning

Using a subglottic suctioning endotracheal tube can cause clogged lumens. This makes it difficult and sometimes impossible to clear out using air bolus.

THE NEED FOR CHANGE WAS CLEAR. THE STRUGGLE WITH CLOGS IS OVER.

3 Simple Steps: Rinse. Suction. Clear.

Rinse.

MICROCUFF* Subglottic Suctioning ETT enables the safe use of saline rinsing to effectively clear clogs.7,9

  • Suction lumens clog up to 44% of the time -preventing effective suctioning of secretions.9
  • Saline rinsing is more effective than air bolus at loosening and clearing clogged suction lumens.9
  • The suction valve with integrated rinse port enables both suctioning and saline rinsing, without opening the suction circuit, preventing cross-contamination to both caregiver and patient.7

Suction.

Suctions Secretions More Effectively and Efficiently…with a Push of a Button

  • When clogged lumens prevent effective suctioning, subglottic secretions are known to accumulate up to 13mL per hour, increasing the risk of microaspiration.2
  • With reports of suctioning dysfunction as high as 48% due to clogs,1,2 suctioning is inconsistent.

Clear.

A Clear Change for Clearly Superior Results

  • A polyurethane cuff reduces channel formation, minimizing cuff leakage and enabling the use of saline6.
  • Polyurethane cuffs prevent fluid leakage, demonstrating 93% less mircroaspiration than TaperGuardtm Evac ETT.7
  • Because saline rinsing is more effective than air bolus at clearing clogs, subglottic secretions are suctioned more effectively9.

MICROCUFF* Adult Endotracheal Tube

Provides A Superior Tracheal Seal (3,4) … Proven to Reduce Leakage

Micro-aspiration of potentially infectious secretions through gaps in the endotracheal tube cuff is known to be a leading cause of VAP1. The cuff seal is the final barrier that protects the lungs from aspiration of potentially infectious pharyngeal secretions. When intubated, conventional high volume, low pressure (HVLP) PVC cuffs create channels that permit fluid to leak through the cuff and into the lungs.

MICROCUFF* features an advanced microthin polyurethane cuff, allowing channels to “self-seal” for increased protection against fluid leakage:

  • Polyurethane (10 microns) cuff membranes are substantially thinner than conventional PVC cuffs (50-80 microns)
  • Provides an effective seal at low cuff pressure
  • Designed for better contact with tracheal contour
  • Allows for greater visualization of vocal cords when cuff is deflated
  • Puncture strength is almost double compared to conventional2
  • Burst pressure is more than double compared to conventional2

The better the seal, the less micro-aspiration, the lower the risk of VAE and VAP.

“In conclusion, our in-vitro experiments show the recently introduced MICROCUFF* tube cuff to be the only one of the tested HVLP endotracheal tube cuffs that effectively prevents fluid leakage around the tracheal tube when cuff pressure was set to 30 cm H2O or less.”

MICROCUFF* Pediatric Endotracheal Tube

A new standard for pediatric airway management

MICROCUFF* Pediatric Endotracheal Tubes, designed specifically for the pediatric anatomy, offer the advantages of a cuffed tube, reducing tracheal trauma and providing a sealed airway that allows minimal and low flow anesthesia use.Its short and cylindrical cuff membrane compensates for different sized and shaped pediatric airways, reducing the need for replacing oversized tracheal tubes, and resulting in lower re-intubation rates.1

Designed for ideal anatomical cuff placement

  • Advanced microthin polyurethane material (10 microns) permits a true high volume, low pressure (HVLP) cuff, effectively sealing at an average of 11 cm H201, about half the pressure of conventional tubes
  • Anatomically-based intubation depth mark results in correct placement and a cuff-free subglottic zone2
  • Precision bands facilitate and confirm optimal tube placement

Offers the advantages of a cuffed tube with a NEW level of safety

  • Seal with a cuff membrane in the trachea, instead of rigid tube shaft in the cricoids
  • Low rate of re-intubation1, as MICROCUFF* reduces need to replace oversized tracheal tubes, resulting in less patient trauma, time and material costs
  • Reduced risk of aspiration of blood and secretions due to improved seal
  • Sealing with a cuff compensates for different sized and shaped airways
