Hands Free Reflux Angioplasty Case Study

Chameleon™ PTA balloon catheter

View cases utilizing combined occlusion and targeted injection of contrast for hands-free reflux angiography.

Addressing visualization and radiation distance with device dual-functionality

Full AV graft circuit imaging

Inject contrast media while the Chameleon™ PTA balloon catheter is inflated — for visualization of the entire AV graft circuit. With occlusion and injection of contrast combined in one device, this enables visualization with hands away from the radiation source (hands-free).

Hands-free reflux overview

Simultaneous inflation and injection

Ari Kramer, M.D. describes the hands-free reflux angiography procedure.

Use of the Chameleon™ PTA balloon catheter and third port contrast injection at the lesion for hands-free reflux and target area assessment. With the balloon reduced, contrast can be injected and rapidly run in antegrade fashion.
