Stents for Cardiology, Radiology and Vascular Surgery

• Biocompatibility
• Haemocompatibility
• Reduced Inflammatory Response

Finally, a stent that gets along with the human body. Each product in Datascope’s line of Carbofilm™ endovascular stents was specially designed to be in perfect harmony with the human body. Carbofilm coating technology has been proven safe and effective by long-term experience in over 300,000 prosthesis implants worldwide (including tilting disc, bileaflet and biological heart valves). Now, the Carbofilm stents establish a new level of biocompatibility for percutaneous coronary revascularization, with lower stent thrombosis and reduced retenosis, even in high-risk patients.¹

Carbofilm Technology:

• Made of Carbon atoms, (as are diamonds and graphite).

Carbofilm Key Features:²

• Enhances haemo and biocompatibility
• Improves tissue interaction and inhibits foreign body reaction
• Improves blood interaction:
  • Preventing clot and thrombus formation
  • Reducing local inflammatory reaction
  • Promoting a well organized layer growth
  • Improves surface endothelialization
• Inhibits complement activation

Carbofilm Properties:

• Application to all kinds of materials
• Application to complex-shaped components
• Carbofilm is extremely thin: 0.5 µm. Such thickness does not alter the morphological and physical characteristics of the substrate
• Carbofilm features high adhesion strength, threshold: 700 kg/cm2.

Mirror Polishing:

The laser slotting technique developed by Sorin produces a cut as narrow as 0.025 mm, and limits the thickness of the material affected from heating to less than 0.005 mm. The electrochemical treatment eliminates the material affected from heating, makes the sharp edges round, and provides a perfect surface finishing level: MIRROR EFFECT.

Carbofilm Cell Structure Key Features:

• Closed Cell Design
• Slotted Tube
• Round Edges
• Thin Struts
• Carbofilm Coating

The cell is build up out of different widths in order to optimize the stents’ performance in expansion, flexure and torsion.

Balloon Expandable Stent Cell Interconnection Scheme:

Cells are connected at the midpoint of the longest curved segments:

• To create elastic joints that increase the overall stent flexibility
• To allow zero shortening upon expansion
• Radiopaque markers at each end of the stent
