Seledora® Coronary Scoring Balloon Catheter– Product Overview

“Precise lesion preparation” and “vascular functional restoration” are the main themes in current coronary interventional therapy.

Compared with common balloon angioplasty, which compresses plaques in a disordered manner, scoring balloons offer a more targeted solution. On the one hand, the scoring elements focus pressure on the lesion, enabling controlled plaque modification and reducing the risk of irregular dissections that could restrict blood flow. On the other hand, for moderate to severe, especially circumferential calcified lesions that are often hard to cross with other devices, scoring balloons can embed their elements into the plaque and dilate it at low pressure. This approach helps to gradually open the lesion, creating favorable conditions for further lumen preparation and maintenance—— achieving true precise lesion preparation.

The Seledora® Coronary Scoring Balloon Catheter features a deliverability profile of 0.0165″, equivalent to a conventional pre-dilatation balloon. It is equipped with three triangular nylon scoring ridges, each 0.42 mm in height, evenly distributed at 120° intervals along the balloon’s proximal and distal ends. This design ensures excellent lumen gain while maintaining good crossability.

Ex Vivo Simulation Results
The Seledora® scoring balloon demonstrated uniform and consistent scoring morphology aligned with the direction of blood flow, indicating effective and controlled plaque modification.

Clinical Benefits

The immediate lumen gain in the test group showed no statistically significant difference from the control group, confirming the non-inferiority of the Seledora device. Safety and secondary efficacy outcomes were also comparable between the two groups.

By enabling low-pressure, focused dilatation and directional, controlled plaque scoring, the Seledora® Coronary Scoring Balloon Catheter facilitates effective lumen gain and precise lesion preparation. This paves the way for optimized lumen modification and maintenance, enhances the drug release performance of DES (drug-eluting stents) and DCB (drug-coated balloons), reduces restenosis, ensures long-term treatment efficacy, and ultimately benefits the patient.
