Product details

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. The grooves relieve the stress and stop dissections from propagating.

Product design

This is an illustration of the Chocolate™* PTA balloon inside the vessel with numbered callouts.
  1. Inflation: During inflation, the cage causes the balloon to form a series of segmented pillows and grooves along the entire lesion.
  2. Balloon: The balloon is confined to the cage during inflation, preventing dog-boning, and protecting healthy tissue.
  3. Cage: The nitinol cage expands with balloon, protecting the vessel from torsional stresses and minimizing dissections.1
  4. Pillows: The pillows apply force to create small dissections that are necessary for effective dilatation. 
  5. Grooves: The grooves relieve the stress and stop dissections from propagating.

Drs. Laiq Raja and Mehdi Shishehbor discuss their use of the Chocolate™* PTA balloon, including in BTK cases.
