摘要： A body implantable stent is formed of a plurality of strands arranged in two sets of coaxial helices, wound in opposite directions to form multiple crossings. At selected crossings, the adjacent strands are welded to one another, while at the remaining crossings the strands are free for limited movement relative to one another. The welds are formed in patterns that preferably enhance radial strength and rigidity, while having a minimal impact on axial bending flexibility. Preferred weld patterns in this regard include rings or circumferential rows, and helices, particularly with a steeper pitch than that of the strands. Stent fabrication preferably involves resistance welding at the crossings, and use of a tool to reuniformly compress the stent around and against the distal end region of a balloon catheter used later to deliver the stent to a treatment site.
摘要翻译：身体可植入支架由多个绞合线构成，所述股线布置成两组同轴螺旋，沿相反方向缠绕以形成多个交叉。在所选的交叉处，相邻的线条彼此焊接，而在剩余的交叉处，线条相对于彼此有限的移动是自由的。焊缝以优选增强径向强度和刚度的图案形成，同时对轴向弯曲柔性具有最小的影响。在这方面，优选的焊接图案包括环或周向排和螺旋，特别是具有比线的陡峭的间距。支架制造优选地涉及在交叉点处的电阻焊接，以及使用工具将支架均匀地压缩在球囊导管的远端区域周围并抵靠以后用于将支架输送到治疗部位的远端区域。

摘要： An intravascular catheter having an elongated tubular body with a proximal portion, a distal portion and a lumen extending therebetween. The tubular body is formed with: (a) an inner layer of a blend of (i) about 10-25 weight percent of a polyester-polyurethane having a durometer of from about 45D-55D, and (ii) about 38-53 weight percent of a polyester polyurethane having a durometer of from about 65D-75D; (b) a reinforcing means at least partially surrounding the inner layer; and (c) an outer layer comprising a blend of (i) about 10-25 weight percent of a polyester-polyurethane having a durometer of from about 45D-55D and (ii) about 38-53 weight percent of a polyester-polyurethane having a durometer of from about 659D-75D.

摘要： A diagnostic catheter comprises an inner layer of substantially unmodified polyamide over which is a reinforcing means and an outer layer of polymer having a hardness of 50 Shore D to 70 Shore D, along with a suitable radiopaque filler. Affixed either directly to the end of the above tubular body or to a stem member secured to that tubular body is a soft-tip formed from a blend of PEBA whose hardness is such that the catheter can be Considered as having an atraumatic tip. The resulting catheter exhibits excellent torque and column strength characteristics while providing a relatively large diameter lumen for a given outside diameter.
