    • The present invention provides a catheter balloon having an advantageous cone design. In particular, the catheter balloon has at least one cone section with a volume in mm3 such that, when the ratio of one cone volume to the transverse cross-sectional area in mm2 of the inflated median section is at least about 2.1 mm. In certain applications, the advantageous cone design can assist in the preferential expansion of the cone sections prior to any significant expansion of the median section. The balloon can thus advantageously be utilized as a component of a balloon catheter or prosthesis delivery system, also provided via the present invention. When so utilized, the inventive balloon can assist in reducing any shifting of the balloon and/or prosthesis during inflation or delivery, respectively. Methods of utilizing the balloon catheters in dilation procedures, as well as the prosthesis delivery systems to deliver prosthesis, are also provided.
    • 本发明提供一种具有有利的锥体设计的导管球囊。 特别地,导管球囊具有至少一个具有以mm 3为单位的体积的锥形部分,使得当一个锥体体积与横截面积的比值(mm 2)至少约2.1mm。 在某些应用中,有利的锥形设计可以在中间部分的任何显着膨胀之前有助于锥形部分的优先膨胀。 因此,气囊可以有利地用作也通过本发明提供的球囊导管或假体递送系统的组件。 当这样使用时,本发明的气囊可以分别有助于减少气囊和/或假体在充气或输送期间的任何移动。 还提供了在膨胀程序中使用球囊导管的方法以及用于输送假体的假体输送系统。
