摘要： The present invention is for a stent delivery guide catheter to be used in percutaneous transluminal coronary angioplasty (PTCA). The stent delivery guide catheter consists of a guide catheter body having proximal and distal ends with a cylindrical outer wall and a coaxial inner wall defining a inner lumen. A bladder is formed between the inner and outer walls and is in fluid communication with an inflation lumen. A radially expandable and compressible stent is located inside the guide catheter body and is removably attached to the inner wall in the area of the bladder. In use, a balloon catheter is slid inside the guide catheter with the balloon positioned under the stent. When the bladder is inflated, the stent is compressed radially inward and is deposited on the balloon catheter. The present invention can also be used without the stent to facilitate the exchange of an over-the-wire balloon catheter. The balloon catheter is pulled proximal to the inflatable bladder inside the guide catheter. The bladder is then inflated and compressed to hold the guidewire while the balloon catheter is exchanged.
摘要翻译：本发明涉及一种用于经皮腔内冠状动脉血管成形术（PTCA）的支架输送导管。支架输送导管由具有近端和远端的引导导管主体组成，其具有圆柱形外壁和限定内腔的同轴内壁。膀胱形成在内壁和外壁之间并且与膨胀腔流体连通。径向可膨胀和可压缩的支架位于引导导管主体内部并且可移除地附接到膀胱区域中的内壁。在使用中，气囊导管在引导导管内滑动，气囊位于支架下方。当膀胱膨胀时，支架被径向向内压缩并且沉积在球囊导管上。本发明也可以在没有支架的情况下使用来促进线上球囊导管的交换。气囊导管被拉近到引导导管内的可充气囊。然后在更换气囊导管的同时使膀胱充气并压缩以保持导丝。
