Chocolate PTA
Balloon Catheter
for percutaneous transluminal angioplasty
The Chocolate™* PTA balloon is the only nitinol-caged balloon with controlled dilatation, designed for 1:1 vessel sizing.
Overview
The Chocolate PTA balloon is a semi-compliant balloon that is encased in a nitinol-constraining structure, or cage, that allows for 1:1 vessel sizing.
During inflation, the cage causes the balloon to dilatate in a controlled manner, alleviating dog-boning and overinflation. The cage also causes the balloon to form a series of segmented pillows and grooves along the entire lesion. The pillows apply force to create small dissections that are necessary for effective dilatation.
Indications
The Chocolate PTA balloon catheter is intended for balloon dilatation of lesions in the peripheral vasculature, including the iliac, femoral, ilio-femoral, popliteal, and infra-popliteal arteries.
Product details
Product design
- Inflation: During inflation, the cage causes the balloon to form a series of segmented pillows and grooves along the entire lesion.
- Balloon: Balloon is confined to the cage during inflation, preventing dog-boning and protecting healthy tissue.
- Cage: Nitinol cage expands with balloon, protecting the vessel from torsional stresses and minimizing dissections.1
- Pillows: The pillows apply force to create small dissections that are necessary for effective dilatation.
- Grooves: The grooves relieve the stress and stop dissections from propagating.
