Conclusions

The STAR Tumor Ablation System:

  • Was safely & effectively used in the treatment of metastatic spinal tumors
  • Allowed RFA treatment of previously untreatable lesions which resulted in reduction of pain that was not controlled with systemic or radiation therapy
  • In certain cases with posterior wall involvement, posterior extension of tumor was halted
  • Did not hinder or delay other therapies

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.

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
