摘要： A dilatation balloon is fabricated according to a process that forms cavities and indentations in the balloon and/or catheter sections. A length of tubing is axially elongated and radially expanded in a form to provide the requisite biaxial orientation and strength. Then, an excimer laser or another type of laser or mechanical material removal tool is used to remove the polymeric material, virtually without thermal effects. Cavities in the sleeve sections of the balloon are defined and if desired, indentations in the cone sections are defined. Material removal, particularly near the balloon sleeves enables a thinner, more flexible bonding area between the catheter shaft and the balloon. Further, the indentations along the cone sections enables tighter wrapping of the balloon for a reduced delivery profile. Rigidity near the sleeves is reduced for better maneuverability of the catheter in tortuous passageways.
摘要翻译：根据在球囊和/或导管部分中形成空腔和凹陷的方法制造扩张球囊。一段长度的管材是轴向伸长的并以一种形式径向扩张以提供必要的双轴取向和强度。然后，使用准分子激光器或其他类型的激光或机械材料去除工具来去除聚合物材料，实际上没有热效应。气囊的套筒部分中的腔被限定，并且如果需要，限定锥形部分中的凹陷。材料去除，特别是靠近气球套筒，能够在导管轴和球囊之间形成更薄，更灵活的粘结区域。此外，沿着锥形部分的凹陷使得气囊能够更紧密地包裹以减少输送轮廓。袖子附近的刚性减少，导致导管在弯曲通道中的更好的机动性。

摘要： A stent delivery system is disclosed for delivering and deploying a radially expandable stent at a strategic orientation and location in a body vessel. The delivery system includes an elongated flexible tubular shaft sized suitably for insertion into the body vessel. A stent deployment assembly includes a distal transition portion supporting a dilator device adapted for radial expansion about a longitudinal axis of the deployment assembly from a non-expanded condition to a radially expanded condition. The dilator device is configured to support the stent thereon in the non-expanded condition and in predetermined orientation relative the deployment assembly. A rotational clutch assembly rotatably mounts the transition portion to a distal portion of the tubular shaft such that the deployment assembly is substantially torsionally isolated from the tubular shaft, about a longitudinal axis of the clutch assembly. This enables the stent deployment assembly to rotate substantially independently of the tubular shaft for strategic orientation of the dilator device during advancement through the body vessel.

摘要： Disclosed are stent delivery apparatus and methods for moving a balloon catheter carrying a stent through a body vessel without the stent slipping from the balloon are provided. In general, the stent delivery system includes a stent stopper that impedes the stent from slipping from the balloon. The stent stopper is sized to serve as a barrier to the stent as it is carried on the balloon. In a specific embodiment, the stent stopper is formed from a material that encircles the proximal end of the balloon and abuts the proximal end of the stent. The stent stopper material expands with expansion of the balloon and collapses with deflation of the balloon. In some embodiments, the stent stopper material has a thickness that is about equal to or greater than the thickness of the stent so as to form a barrier against the stent and impede the stent from slipping off the proximal end of the balloon.

摘要： A guidewire apparatus for a medical device that includes an expandable guidewire section that can be locked in an expanded state. In one use, the expandable section can be temporarily locked to a working element of a medical device to facilitate the transmission of torque from the guidewire to the medical device. Hence, this configuration may be utilized to aid in orientation of the working element with a vessel side branch by providing the user with the ability to apply a rotational force to the distal end of the stent delivery system. Another use includes docking the expandable section near an opening into a guidewire lumen at the catheter tip. This configuration is particularly useful in forming a smooth transition between the guidewire and the catheter tip to reduce the phenomenon of fish-mouthing.

The multilayered material can include at least two layers having a boundary layer therebetween. The boundary layer is configured to inhibit cracks from propagating from a first layer-to a second layer. The different layers can be comprised of the same materials or different materials. It can be preferred that the multilayered material have layers that are comprised of resiliently-flexible materials, shape memory materials, and/or radiopaque materials.
