Scoreflex

Coronary Dilatation Catheter

Focused Force Angioplasty for Controlled Lesion Preparation 

Focused Force Angioplasty for Safe and Controlled Dilatation

Scoreflex is a focused force dilatation balloon with a dual-wire system which creates a focal stress pattern to facilitate safe and controlled plaque modification at lower resolution pressure.

Advance a standard guidewire across the target lesion.

Advance Scoreflex over the guidewire and cross the target lesion.

Inflate the Scoreflex balloon in a stepwise fashion.

Withdraw the deflated Scoreflex once the desired result is achieved.

Scoreflex Construction

TIP

A short rapid exchange tip with the guidewire exit port proximal to the tip

WIRE

A nitinol integral wire, welded from tip to hypotube, serving as one of the scoring elements

MARKERS

Two radiopaque markers on the integral wire aligned to the balloon shoulders

The (conventional) guidewire exits proximal to the tip and acts as the second scoring element

Low Dilatation Pressure, Big Dilatation Effect

Scoreflex is a focused force dilatation balloon that comes with a dual wire system which enables effective dilatation under lower inflation pressure. For optimal results, a gradual step-up inflation protocol should be adopted

Applications

  • Lesion preparation for stents, scaffolds, drug-coated balloons
  • Calcified and fibrotic lesions
  • Ostial lesions
  • Bifurcation lesions
  • Long diffused lesions
  • Small lesions without need of stenting
  • In-stent restenosis
