摘要： Endoprosthesis for delivery in a body lumen is provided. The endoprosthesis includes an annular element defined by a set of interconnected strut members, each strut member including a first end and a second end. The first end of selected pairs of circumferentially-adjacent strut members of the annular element are interconnected to define apices proximate a first longitudinal side of the annular element and the second end of selected pairs circumferentially-adjacent strut members are interconnected to define apices proximate a second longitudinal side of the annular element. At least one of the selected pairs of circumferentially-adjacent strut members has a modulator disposed proximate the apex defined there between, the modulator having a first mode to allow expansion of the annular element from an unexpanded configuration toward an expanded configuration and a second mode to resist contraction of the annular element from the expanded configuration toward the unexpanded configuration.

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，导致导管在曲折通道中的更好的机动性。

摘要： A system for delivering a medical device, such as an angioplasty balloon, includes two catheter shafts. The distal portion of a first shaft includes a first balloon and is narrower than the proximal portion. A second catheter shaft includes a second balloon and is connected to a medial portion of the first shaft. The second shaft includes a guidewire passageway which is in communication with the passageway of a third shaft that is removably connected to the first shaft. The distal tips of the first and second balloons are connected together to allow the system to be advanced to an anatomical site using a single guidewire. A second guidewire may be used to separate the distal ends of the balloons and to position the balloons at vascular bifurcation. A stent can be crimped onto the balloons such that inflation of the balloons implants the stent within the bifurcation.

摘要： A device and method for locking onto a guidewire. The device includes an element transversely movable along the guidewire. The element may have a plurality of portions and a biasing member connecting first and second portions of the transversely moveable element such that the first portion and another of the portions are movable from a first position, where the first portion and the other portion are aligned with respect to one another, to a second position, where the first portion is no longer aligned with respect to the other portion, the device being locked to the guidewire in the second position. The device can be used for locking an embolic protection device including a filter to a guidewire that is adapted to be introduced into a vascular system of a patient.

摘要： A stent delivery catheter system for accurately positioning a stent in a bifurcated vessel is disclosed. The system includes a catheter having a terminal portion and distal tip that is placed in a main branch of the vessel proximate the bifurcation. A fixed guidewire is attached to distal tip. A port is defined in the terminal portion of the catheter. The port is aligned with an ostium of a side branch of the bifurcated vessel to allow the passage of a stent delivery device, such as a balloon catheter having a stent crimped thereon, into the side branch. Radiopaque bands are positioned on opposite ends of the port. A positioning balloon is included on a surface of the catheter opposite the port and is selectively inflatable to position the radiopaque bands adjacent the side branch ostium. The radiopaque bands are referenced to place the stent proximate the side branch ostium.

摘要： Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration. The annular elements are longitudinally aligned and connected at connection locations with connectors, wherein at least one of the connectors is constructed of a bio-absorbable material.
