✦ Synopsis

We present a case to illustrate a new stent design that specifically allows treatment of bifurcation lesions. The device is the JoStent (JoMed, Rangendingen, Germany). This bare stent is constructed so that at each end the stent mesh has 8 cells making up the circumference, whereas the central portion is composed of 4 cells only (Fig. 1). This construction allows expansion to 3.5mm within the central cells, permitting passage of an angioplasty wire, balloon, and further stents, to protect major side branches.

The patient was a 42-year-old male, with effort angina and an eccentric 95% stenosis of the mid left anterior descending artery (LAD), overlying and involving a large first diagonal branch (Fig. 2). We elected to treat this with angioplasty and elective stenting. Two 0.014Π‰ Hyperflex wires (Bard USCI, Billerica, MA) were passed to the distal LAD and diagonal. The vessel diameter by QCA was 2.8mm. Predilatation was performed using a 3.0 Samba Rely balloon (Bard USCI) taken to 14 atmospheres within the

## Abstract Coronary angioplasty of bifurcation lesions remains a technical challenge and is believed to result in low procedural success associated with the risk of side‐branch occlusion. Furthermore, long‐term results are associated with a high rate of reintervention. The aim of the study was to

We report on a new technique of stenting a bifurcation lesion. A manually bent 180Β°hinged slotted tube stent was implanted using the kissing balloon technique (resembling two trouser legs). In addition, the proximal part of the main vessel was covered with a stent mounted on two balloons correspondi

## Abstract We report a new stenting technique employed in 20 consecutive patients to treat true bifurcation lesions using the Cypher stent (Cordis, Warren, NJ). Both stents are advanced at the site of the bifurcation. The proximal marker of the side‐branch stent must be situated in the main branch
