Study Outcomes

Reduce procedure time, fluoroscopy time, and contrast volume1

The Chameleon™ PTA balloon catheter provides a more efficient procedure with simpler, more intuitive solutions, combining angioplasty and imaging in one device.

Based on a multicenter retrospective study.
Note: Risks may include vessel dissection, perforation, rupture, spasm, or need for additional intervention.

Study design and patient statistics

Dialysis access cephalic arch (CA) and central venous (CV) stenosis cases

A multicenter retrospective study.

Comparison of outcomes between a standard PTA balloon catheter (Group A) and the Chameleon™ PTA balloon catheter (Group B), using multiple regression corrected for lesion location and length.

  • No significant gender differences between groups
  • Comorbidities were similar to national rates in both groups (hypertension, coronary artery disease, and diabetes)
Sample size (n=68)

Group A:
34 Patients (Standard PTA balloon catheter)

Group B:
34 Patients (Chameleon™ PTA balloon catheter)
