    Abstract: Multilayer balloon for a catheter includes at least a first layer, a second layer, and a third layer having a combined wall thickness. The first layer is made of a first polymer material having a first maximum blow-up-ratio. The second layer made of a second polymer material having a second maximum blow-up-ratio greater than the first maximum blow-up-ratio, and the second layer is an inner layer relative to the first layer. The third layer is made of a third polymer material having a third maximum blow-up-ratio greater than the second maximum blow-up-ratio, and the third layer is an inner layer relative to the second layer. The at least first, second, and third layers define a compliance less than that of a single layer balloon made of the first polymer material with a wall thickness equal to the combined wall thickness. Method of making of multilayer balloon is also provided.

    Abstract translation: 用于导管的多层气囊包括至少第一层,第二层和具有组合壁厚度的第三层。 第一层由具有第一最大吹胀比的第一聚合物材料制成。 由具有大于第一最大吹胀比的第二最大吹胀比的第二聚合物材料制成的第二层,而第二层是相对于第一层的内层。 第三层由具有大于第二最大吹胀比的第三最大吹胀比的第三聚合物材料制成,第三层是相对于第二层的内层。 至少第一层,第二层和第三层限定了比由第一聚合物材料制成的单层气囊的顺应性更小的壁厚,其厚度等于组合的壁厚。 还提供了制造多层气囊的方法。

    Abstract: A guidewire for use in intravascular procedures has an inner coil that is radiopaque and an outer coil that is non-radiopaque at the distal end of the guidewire. The radiopaque inner coil is visible under fluoroscopy so that the physician can monitor the location of the distal end of the guidewire during a procedure. The inner coil and the outer coil can be formed from a single wire or a multi-filar wire. The inner coil and the outer coil can have any of the following cross-sections for enhanced torquability: I-beam; vertical rectangular; vertical ellipse; square; peanut shape; vertical hexagonal; horizontal hexagonal; and horizontal ellipse.
