Infection Control with TYRX Absorbable Antibacterial Envelope
TYRX Antibacterial Envelope is:
- Supported by 6 clinical studies proving its efficacy to help prevent CIED infection
- Specifically designed to aid in the stabilization of CIED and INS placement
How It Works:
- Minocycline and Rifampin elute locally into the tissue pocket, enabling MIC levels to be reached within 2 hours of implantation and maintain for a minimum of 7 days: locally delivered, adjunctive antibacterial protection8
- Mesh substrate absorbs into the body in ~9 weeks; no change necessary in surgical technique during replacement and revision
- After absorption, no foreign body nidus for potential infection
Four Reasons Physicians Should Consider Using the
TYRX Absorbable Antibacterial Envelope – "TIME"
- Reduces the chance of Twiddler Syndrome9
- Helps prevent Infection2
- Reduces the chance of device Migration2
- Reduces the chance of device Erosion2
Stabilize CIED Placement. Help Prevent CIED Infection.
Bacterial infection is one of the most common causes of CIED complications … and is on the rise
In a retrospective analysis examining CIED implants between 1993-2008, investigators found a 210% increase in the incidence of infection with CIED implantation over the course of this 15-year time period.
This increased rate of infection was likely due to:1
- Older patients receiving devices
- More patient comorbidities
- Longer procedures
- Mix of CIED devices is changing
- Number of pulse generator replacements and upgrades are increasing
- More resistant S aureus and coagulase (-) Staphylococcus species (e.g., S epidermidis)
