BiOSS® Clinical Programme – State of the Art – BiOSS LIM® Stent – The Novel Option for Coronary Bifurcation Treatment

Editorial Process

The BiOSS LIM® (Bifurcation Optimization Stent System, Balton, Warsaw, Poland) stent is a coronary, dedicated bifurcation, balloonexpandable stent made of 316 L stainless steel with a strut thickness of 120 μm. It is covered with a mixture of a biodegradable polymer and the antiproliferative substance: sirolimus. The stent consists of two parts (the proximal with a larger diameter in relation to the distal one) connected with two struts (average 1.5 mm length) at the middle zone. The stent is crimped on a bottle-shaped semi-compliant balloon (Bottle®, Balton, Warsaw, Poland). Our intravascular ultrasound (IVUS) study revealed that the construction of the BiOSS® stent allows easy access to the side branch, similar to the classic stent lumen enlargement with less injury to the area adjacent to the most sensitive part of the bifurcation. The BiOSS LIM® stent has already been thoroughly investigated: initially in the First-In-Man registry with 60 patients, then in the registry in a high-risk population with distal left main stenosis and finally in a randomised clinical trial POLBOS II. The long-term clinical results were satisfactory and closely related to the high-risk profile of the treated population. Our data demonstrated that the simple and fast bifurcation treatment with a single dedicated bifurcation sirolimus-eluting stent (BiOSS LIM®) is feasible and highly successful.
