Retrospective Analysis Study Shows CentrosFLO® Long-Term Hemodialysis Catheter Tip Design Offers Greater Patency


The Merit Medical CentrosFLO long-term hemodialysis catheter’s self-centering split-tip design has a greater separation between the arterial and venous tips than the symmetric-tip designed catheter. Its design is intended to optimize catheter patency and reduce fibrin sheath formation, thrombosis and vessel wall occlusions by keeping the tips of the catheter centered in the vessel and away from the vessel wall.

In May of 2013, a retrospective study was completed by Dr. Saravanan Balamuthusamy (“Dr. Bala”) at Angiocare, Vascular and Interventional Nephrology, in Tucson, Arizona. The performance and safety of a new self-centering, split tip hemodialysis tunneled catheter was compared with a symmetric-tip catheter in 58 patients.

Study Conclusion1
The study results indicated that the CentrosFLO self-centering, split-tip catheter had statistically greater patency after 3 months with similar clearance and blood flow.

Split-Tip Design
(n = 38)
(n = 20)
Patency 94.7% 75.0% P = 0.04
Mean Clearance (Kt/V)2 1.483 1.423 NSD4 (p = 0.48)
Mean Blood Flow (ml/min)2 393.93 381.63 NSD4 (p = 0.27)

1 Study data on file.
2 Mean value during the three-month follow-up period.
3 Mean clearance and mean blood flow did not include data from patients with no catheter patency.
4 NSD = Not Statistically Significant, p > 0.05 (t-tests).

New! 7.5F ReSolve® Locking and Non-Locking Drainage Catheter

We are now pleased to offer the ReSolve® Locking and Non-Locking Drainage Catheters in 7.5F. These catheters are indicated for percutaneous drainage of fluid from body cavities. Some of the drainage procedures performed with these catheters are abscess, nephrostomy and cyst.

For many fluid collections, a 6.5F catheter is often too small to drain the fluid, but an 8.5F catheter is too large for the patient. These new catheters are great for those fluid collections and patients where an in-between catheter is needed.

These catheters continue to offer

  • Smooth transitions
  • Large drainage holes
  • Hydrophilic coating
  • Kink resistance

Merit Medical’s Safeguard® Allows Parents to Hold Their Babies After Heart Surgery

I have a grandson that is 20 months old and who is in perpetual motion. If he’s awake, his inquiring mind has him looking, touching and listening to everything. Recently he injured his hand, pinching it in a door. It wasn’t serious, but all of a sudden he went from running around his playroom, to wanting to be held by his mother. It was as if it didn’t hurt if she was holding him.

In reflecting on this, I think of children who undergo a diagnostic or interventional cardiology procedure in the Pediatric Cath Lab, such as septal defects (ASDs or VSDs) or valve defects, such as pulmonary valve stenosis, among others. When the procedure is finished and they are in recovery, these young patients have the same desire to be held that my grandson exhibited. Merit Medical’s Safeguard Pressure Assisted Device gives children the ability to be held by their parents after heart surgery.

In an article in the November 2006 issue of Cath Lab Digest, Jill Dykstra, RN and Kathy Laird, RN with the Congenital Heart Institute at the Arnold Palmer Hospital for Children, in Orlando, Florida authored an article titled, Use of the Safeguard Pressure-Assisted Dressing for Patients Less than 15 kg Following Cardiac Catheterization. In it they stated: “…Prior to implementation of the Safeguard hemostasis device, methods for maintaining hemostasis included pressure dressings that did not allow for the parents to hold the infant…”

This 6-month study found that “…the Safeguard device does not restrict mobility and allows for parental contact immediately post-procedure.

The Safeguard gives clinical personnel a pressure assisted device that promotes hemostasis, decreases occurrences of re-bleeds, and most important, gives a child the comfort of being in the arms of a parent.

Merit Medical’s ConcierGE® Has Better Kink Resistance and 1:1 Torque Than Leading Guiding Catheter Brands

THE BAR HAS BEEN RAISED by Merit Medical with the introduction of the Merit ConcierGE Guiding Excellence Catheter.

In an independent survey, approximately 40% on Interventional Cardiologists indicated that their current guiding catheter does not meet their needs for kink resistance.

Designed in 5F, 6F, 7F, and 8F, ConcierGE is the first guiding catheter designed with a higher level of guiding excellence.

Kink Resistance
The ConcierGE has approximately
30% more kink resistance*
than the leading brands, facilitating
the advancement and withdrawal of
interventional devices.
1:1 Torque
The ConcierGE test results prove
that it has better 1:1 torque
response** than the leading
brands, promoting quicker catheter
seating with less whipping.*

Each feature of the guiding catheter is designed to give you added confidence in difficult cases by optimizing clinical benefits without compromise during coronary angioplasty.

New Studies Highlight Benefits Of STAR Tumor Ablation System For Patients With Spinal Tumors

San Jose, Calif. – Feb. 18, 2014 –Two studies presented at the American Society of Spine Radiology (ASSR) 2014 Annual Symposium in Miami highlighted the benefits of Targeted Radiofrequency Ablation™ (t-RFA) therapy with the DFINE STAR™ Tumor Ablation System. The studies demonstrated the ability of the STAR System to provide significant pain relief to patients suffering from painful spinal metatases; in many cases, these patients had not responded to standard therapies, such as radiation or chemotherapy. The first study, conducted by Bassem Georgy, M.D., Assistant Clinical Professor of Radiology at the University of California, San Diego, noted improvement in pain and functional status (quality of life) in all patients. The study also concluded that the targeted and minimally invasive nature of the STAR System allowed treatment of all of the studied tumors regardless of their location. The second study, conducted by Jack Jennings, M.D., PhD, Director of Musculoskeletal and Spine Interventions at the Mallinckrodt Institute of Radiology in St. Louis, demonstrated the value of the STAR System in treating patients who were not responsive to other standard treatments and who had tumors very close to the spinal cord (posterior lesions). In addition to relieving pain, the study concluded that the STAR System had successfully destroyed the lesions, and that in many patients no regrowth was observed during the study period.< “We are pleased with the continued success of STAR in providing pain relief to the many cancer patients suffering from spinal tumors,” said Greg Barrett, Chief Executive Officer of DFINE. “The therapy continues to gain momentum and we are gratified to see more clinicians embracing the technology to help their patients.” About STAR™ Tumor Ablation System The STAR Tumor Ablation System does not treat cancer. It was cleared by the FDA in 2010 for providing palliative treatment (e.g., pain relief) by ablation of metastatic malignant tumors in a vertebral body. With its use of targeted radiofrequency (RF) energy, the STAR System enables physicians to achieve pain relief through the use of a single, minimally invasive procedure that may be compatible with both chemo and radiation therapy. As with all surgical procedures, there are risks and contraindications associated with the STAR System which are described in the product labeling.  The STAR System is available at more than 200 institutions in the U.S. For more information regarding spinal tumors or to find a physician, visit About STAR™ Tumor Ablation System t-RFA with the STAR System does not treat cancer.
