摘要： The invention includes a catheter having an elongate main body having a proximal section and a distal section. The elongate main body further includes a first guidewire lumen and a second guidewire lumen. Each guide wire lumen including a proximal port and a distal port in communication with an external environment. The proximal port of the first guidewire lumen spaced by a gap from the distal port of the second guidewire lumen. In accordance with a further aspect of the invention, the catheter includes a plurality of overlapping stiffening members defined along at least a portion of a length between the distal end and the proximal end of the elongate main body.

摘要： The present invention relates to a stent delivery system and a process for mounting a stent onto a delivery system. More specifically, the present invention relates to a method of loading a stent onto a balloon and mounting the stent balloon assembly onto a catheter. The premounting of the stent onto the balloon subassembly allows the stent to be crimped in a way that the crimping recoil can be compensated and stent retention is kept at a maximum.
摘要翻译：本发明涉及支架输送系统和将支架安装到输送系统上的方法。更具体地，本发明涉及一种将支架装载到球囊上并将支架气囊组件安装到导管上的方法。将支架预先安装到气囊子组件上，使得支架可以以压接反冲补偿的方式进行卷曲，并且将支架保持力保持在最大程度。

摘要： An expandable stent for implantation in a body lumen, such as coronary-artery, and methods for manufacturing such a stent are provided, whereby the stent comprises at least one radially expandable cylindrical crown covered with a polymeric tube. The at least one crown is generally aligned on a longitudinal axis of the stent and connected to at least one further stent segment with highly flexible connectors formed from the same or different polymeric material as the crown covering material. In a preferred embodiment the cylindrical crown is loaded or coated with a therapeutic active agent.
摘要翻译：提供用于植入体腔（例如冠状动脉）中的可扩张支架以及用于制造这种支架的方法，由此支架包括被聚合物管覆盖的至少一个可径向扩张的圆柱形冠。至少一个牙冠通常在支架的纵向轴线上对准，并且连接到至少一个另外的支架段，其具有由与冠覆盖材料相同或不同的聚合物材料形成的高度柔性的连接件。在优选的实施方案中，圆柱形冠被加载或涂覆有治疗活性剂。
