摘要： The present invention is a hybrid stent that is defined as having a central section that is balloon expandable and end sections that are self-expanding. The entire stent is mounted on a balloon of a balloon angioplasty catheter. One way to retain the self-expanding portion of the stent onto a balloon onto which it has been nested is to place a cylindrical elastomer tube around each of the self-expanding end sections of the stent. Another way to retain the hybrid stent onto a stent delivery system is to use a conventional sheath that is pulled back to initiate stent deployment

摘要： The present invention is a stent delivery catheter system for placing a stent within a stenosis in a vessel of a human body without the need for either pre-dilatation of the stenosis or post-dilatation of the stent. The primary stenting delivery catheter system utilizes the combination of low profile (i.e., a small outer diameter) with a continuous, smooth and lubricious outer surface extending backward from a tapered distal tip. This design makes it possible for the stent delivery catheter to be pushed through even very tight stenoses without requiring pre-dilatation.
Two versions of the primary stent delivery system are envisioned. The first version is a sheathed primary stenting system with a two-part sheath having a thick-walled proximal section and an ultra-thin distal section that is shrunk down to secure it to the catheter's distal tip. This embodiment differs from the prior art Fischell et al. device that does not shrink its membrane sheath down over the stent and over the balloon catheter's distal tip.
摘要翻译：本发明是一种支架输送导管系统，用于将支架置于人体容器内的狭窄内，而不需要预扩张狭窄或扩张后的扩张。主要的支架输送导管系统利用低轮廓（即，小的外径）与从锥形远侧尖端向后延伸的连续，光滑和光滑的外表面的组合。这种设计使支架输送导管可以通过非常紧的狭窄推动而不需要预扩张。设想了两种版本的主支架输送系统。第一个版本是一个护套的主要支架系统，其两部分护套具有厚壁近端部分和超薄的远端部分，其缩小以将其固定到导管的远端。该实施例与现有技术Fischell等人不同该装置不会将其膜护套向下缩小到支架上并且在气囊导管的远端上方。
