Catheter Patency is Vital for Patients with End-Stage Renal Disease


Catheter patency is vital for the delivery of hemodialysis and effective, long-term vascular access for patients with end-stage renal disease. Tunneled catheter thrombosis, as a result of venous thrombosis or the formation of fibrin sheaths, is a leading cause of catheter failure. Thrombosis can occur when the distal tip of the catheter comes in contact with the vessel wall, which can lead to vessel wall injury and fibrin sheath formation. The tip designs of many available long-term hemodialysis catheters on the market today allow for the tip of the catheter to come in contact with the vessel wall.

The CentrosFLO represents an innovative approach to the design of long-term hemodialysis catheters. The self-centering, curved-tip catheter has a greater separation between the arterial and venous tips compared to a symmetric-tip catheter. Its design is intended to optimize catheter patency, and to reduce fibrin sheath formation, thrombosis and vessel wall occlusions. This unique tip design keeps the tips of the catheter centered in the vessel and away from the vessel wall reducing vessel wall trauma.

An independent retrospective study1 conducted by a vascular access center showed 94.7% patency in the CentrosFLO catheter versus the competitor's catheter, which had a patency rate of only 75% at 3 months. For more information about the CentrosFLO Long-Term Hemodialysis catheter, visit the CentrosFLO product web page.

Multicenter Study Finds Use of Hemostasis Patch Significantly Reduced Risk of Femoral Artery Compromise in Children

Cardiac Interventions News presented in its May/June issue a study at the 2014 scientific sessions of The Society for Cardiovascular Angiography and Interventions (SCAI) entitled, “Femoral Artery Compromise From Cardiac Catheterization in Children–a Multicenter Study by the CCISC (Congenital Cardiovascular Interventional Study Consortium)” by Thomas J. Forbes, MD. It concluded that the use of a 3 Fr sheath and hemostasis patch significantly reduced the risk of femoral artery compromise. The study found that “...when a hemostatic patch was used to seal the wound, the risk of femoral compromise was reduced by approximately two-thirds compared with manual pressure alone.”

The Scion Clo-Sur PLUS P.A.D.™, sold by Merit Medical, is a sterile topical hemostasis pad intended for the local management of bleeding wounds, including vascular procedure sites.

To learn more about the Scion Clo-sur PLUS P.A.D and other products we offer for hemostasis, contact your local Merit Medical Sales Representative.

ReSolve® Non-Locking Drainage Catheter's Smooth Transitions Help with One-Step Technique for Drainage

We have heard from many customers that the ReSolve Non-Locking Drainage Catheter (RNL) is great when using the one-step (direct puncture, trocar) technique when placing these catheters. The smooth transitions of the RNL help to insert the catheter smoothly through tissue without buckling, accordioning, or peeling back during insertion. Some of the drainage procedures that use the one-step technique include: abscess, paracentesis, thoracentesis, nephrostomy, and cyst.

Additional features:
  • Maximized drainage with large drainage holes
  • Decreased friction during placement with the hydrophilic coating
  • Maintain catheter patency via flexible material

To learn more, check out the ReSolve® Locking and Non-Locking Drainage Catheters product webpage.

Safeguard® Pressure Assisted Device: Trusted Femoral Performance Now Available for Radial Procedures

Many of our customers use the Safeguard Pressure Assisted Device for hemostasis following femoral access procedures because they trust its compression, convenience and comfort. Merit Medical now has the Safeguard Radial™ compression device that offers the same trusted compression after radial procedures.

COMPRESSION
  • The Safeguard Radial’s inflatable bulb focuses compression only where you want it
  • It’s easy to adjust air in the bulb (inflation or deflation) using a standard Luer lock syringe
  • Trusted Compression, Comfort & Convenience
  • Now Available For Your Radial Procedures
  • The base plate and the way the band wraps around the bulb provides stable positioning, not occlusion
  • You already know how important patent hemostasis is for a radial compression device and the Safeguard Radial allows you to achieve patent hemostasis with patient comfort as well
CONVENIENCE
  • While your patients come in many sizes, Safeguard Radial comes in one size that will fit them all
  • Having one compression device can reduce your inventory, maximize your precious storage space, and streamline ordering
  • You can use any syringe because Safeguard Radial has a standard Luer lock
  • The inflatable bulb lets you take distal and proximal pulses easily
  • The visibility of the clear bulb window allows you to check for oozing
COMFORT
  • Just like the Safeguard femoral, Safeguard Radial has a soft textile band with no plastic edges and a low profile design
So if you have been using the Safeguard for hemostasis following your femoral procedures, you can trust the Safeguard Radial to provide the same comfortable, convenient performance for radial compression.
