Cobalt-chromium Sirolimus Eluting Coronary Bifurcation Stent

The Bioss Lim C stent is intended for percutaneous transluminal coronary angioplasty (PTCA) in patients with symptomatic coronary artery disease caused by de novo or restenotic atherosclerotic bifurcation lesions (with reference diameters of the distal main vessel ≤ 4.00 mm and proximal main vessel ≤ 5.00 mm).

The stent platform is made of cobalt-chromium alloy L605 and has cylindrical, segmented design with two diameters and repeating elements. The BiOSS LIM C stent consists of:

  • Proximal part – with larger diameter;
  • Distal part – with smaller diameter;
  • Middle zone – with two struts connecting proximal and distal part for opening to side branch.
  • The proximal part is shorter than the distal one. The ratio of the proximal part to the distal one varies between 1.15 and 1.3.

The Rapid Exchange delivery system for stent BiOSS LIM C, consists of:

  • Soft distal part – made of an outer tube, an inner tube and a polyamide balloon. It has two channels – external for balloon inflation and internal for the guidewire (side channel – RX port). Profiled bottle shaped balloon have smaller diameter in distal part and larger diameter in proximal part corresponding with stent shape. Three radiopaque markers are placed on inner tube to identify the stent position within the lesion. In addition, a hydrophilic coating is applied to the distal section of the catheter;
  • Rigid proximal part. – consists of a fluoropolymer coated stainless steel tube and a cap with a single female luer port for inflation and deflation of the balloon.

The stent is delivered to the target lesion, expanded by balloon inflation and remains a permanent scaffolding implant due to its radial force of the stent acting on the vessel wall mimicking bifurcation geometry, preventing carina shift and providing access to the side branch.
