As the only FDA-approved coronary Cutting Balloon, WOLVERINE features a unique design that enables precise modification of soft to calcific plaque across various types of complex coronary lesions. With over 3 decades of proven clinical evidence, The WOLVERINE Coronary Cutting Balloon has been proven to deliver unmatched clinical versatility.

2002年11月15日 · The cutting balloon (CB) is a specialized device designed to create discrete longitudinal incisions in the atherosclerotic target coronary segment during balloon inflation. Such controlled dilatation theoretically reduces the force needed to dilate an obstructive lesion compared with standard percut …

2002年11月15日 · We evaluated whether CB angioplasty could reduce rates of restenosis by its proposed mechanism of controlled injury causing minimal injury response. The results from this well-powered multicenter trial of 1,238 patients randomized to the CB versus PTCA demonstrated that the CB was associated with high rates of procedural success.

sound (IVUS) changes following cutting balloon (CB) and percutaneous transluminal coronary an-gioplasty (PTCA) treatment in in-stent restenosis. Methods. Fifty consecutive patients with in-stent restenosis were randomized to treatment with CB (n = 25) or PTCA (n = 25). The size of the device was selected using IVUS according to a 1:1 de-

2020 年， 美国食品和药物管理局 (FDA) 批准了 Transit Scientific XO Score 经皮腔内血管成形术 (PTA) 记分鞘平台，这是该领域的一项新创新。 这种低调、灵活的金属合金外骨骼不需要专门制造专用球囊，而是将其放置在标准库存球囊上，使其成为一个评分球囊。 一个 XO Score 鞘可用于多个直径 4-8 毫米、长 20-40 毫米的球囊，为医院节省开支。 该设备通过了 FDA 认证，可用于髂动脉、髂股动脉、 腘动脉 、腘下动脉和肾动脉以及合成和/或原生动静脉血液透析瘘。 最近的另 …

In in-stent restenosis, PTCA and CB share similar effects and mechanisms of lumen enlargement. In-stent tissue is mainly redistributed along a larger stent rather than being extruded out of the stent struts. At 24 hours, a significant lumen loss (instant …

2018年3月23日 · “手术成功”，定义为血管造影成功，无任何 mace，定义为心源性死亡、靶血管相关心肌梗死和再次血运重建（ptca/pci 或冠状动脉旁路移植术 [cabg]） 30天

The successfully treated CB group (95 lesions) was matched with the successful conventional angioplasty group (PTCA group) for chronic result assessment in regard to reference vessel size and lesion characteristics.

Cutting balloons (CB), designed to concentrate the dilatation force along three or four blades, are often too bulky to cross truly undilatable lesions and they also may fail to expand at their maximal pressures. Above 16 atm the risk of rupture is quite high, and a ruptured CB might become difficult to reinsert into the guiding catheter.

2005年7月15日 · In the coronary arteries, the CB has been used in randomized studies comparing CB-PTCA (CB percutaneous coronary angioplasty) to PTCA (standard percutaneous coronary angioplasty) as well as in trials for the treatment of ISR [6–10]. All of these trials demonstrated the safety and efficacy of the CB but failed to prove its superiority to ...
