Modulated dilatation

Designed to deliver optimal results without a permanent implant

Chocolate® represents a breakthrough in PTA design. Its unique nitinol constraining structure is designed to provide atraumatic dilatation in the treatment of blocked arteries.

Less trauma = Better acute results.

Key Features

Design: Unique nitinol "constraining structure" (CS) mounted on a semi compliant balloon

• Reduces the strain and trauma induced on the vessel walls during inflation through the use of "pillows"
• Uniformly distributes circumferential forces (calcific or eccentric lesions)
• Modifies plaque via:
  • "Pillows": Vessel dilatation without cutting or scoring
  • "Grooves": Stress relief, plaque modification
• Reduces dissections and may disrupt superficial calcium
• Fast deflation, concentric, low secondary profile – facilitates lesion re-crossing after multiple inflation

• Does not elongate – minimizes stretching of the vessel during inflation
