Study Outcomes
The Chameleon™ PTA balloon catheter provides a more efficient procedure with simpler, more intuitive solutions, combining angioplasty and imaging in one device.
Note: Risks may include vessel dissection, perforation, rupture, spasm, or need for additional intervention.

Study design and patient statistics
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)
Group A:
34 Patients (Standard PTA balloon catheter)
Group B:
34 Patients (Chameleon™ PTA balloon catheter)
