    • An aerodynamic device, such as a projectile includes an elongated forebody, and an aft section secured to the forebody. The aft section acts as a d control device, and includes a connecting member that extends integrally in a conically shaped flared section, for generating a lift force to help stabilize the projectile during forward flight. The aft section further includes a flange that extends from the flared section, and that provides velocity decay and optimal drag, in order to limit the projectile flight and descent within a predetermined safety or emergency range. The flared section is defined between an innermost edge positioned adjacent to the connecting member, and an outermost edge positioned adjacent to the flange. The flange includes a forward facing wall that extends from the outermost edge and that has a height "H" that controls the amount of drag on the projectile, such that the outer diameter of the aft section is less than, or equal to the inner diameter of the gun barrel from which the projectile is fired.
    • 诸如射弹的空气动力学装置包括细长的前体和固定到前体的后部。 后部部分用作拖曳控制装置,并且包括连接构件,该连接构件一体地延伸在锥形扩张部分中,用于产生升力以帮助在向前飞行期间稳定射弹。 后部段还包括从扩张部分延伸的凸缘,并且其提供速度衰减和最佳阻力,以便在预定的安全或紧急范围内限制射弹飞行和下降。 扩口部分限定在邻近连接部件的最内边缘和邻近凸缘定位的最外边缘之间。 凸缘包括从最外边缘延伸的具有高度“H”的向前壁,该高度“H”控制弹丸上的阻力量,使得后部的外径小于或等于内径 枪弹被射击的枪管。

    • A balloon catheter includes a flexible small-diameter guide wire provided with an enlarged-diameter distal end portion, and a flexible elongated tubular shaft with at least one dual-function fluid-conducting lumen adapted to both receive the guide wire extending therethrough, and to communicate pressurized inflation fluid to a distal balloon of the catheter. A distal orifice of the catheter communicates with the balloon and is provided with selective valving means for releasably engaging sealingly with the enlarged distal end portion of the guide wire. Apparatus is disclosed for axially moving the guide wire to effect engagement and disengagement of the enlarged distal end portion with the selective valving means of the catheter shaft. A torquer device is also provided by means of which the guide wire may be rotated relative to the catheter shaft for steering of the guide wire along a vascular pathway. A distal end tapered portion of the catheter shaft provides protection for a joint of the guide wire assembly. The tubular shaft of the catheter may extend through the balloon to provide better pushability for the catheter, especially in versions which employ a comparatively limp material for the balloon. Several alternative constructions for the selective valving means of the catheter shaft and for the enlarged distal end portion of the guide wire assembly are presented.
    • 球囊导管包括设置有扩大直径的远端部分的柔性小直径导丝线和具有至少一个双功能流体导流腔的柔性细长管状轴,其适于两者都容纳延伸穿过其中的导丝,并且 将加压的充气流体传递到导管的远端球囊。 导管的远端孔与球囊连通并设置有选择性阀门装置,用于可释放地与引导线的扩大的远端部分紧密接合。 公开了用于轴向移动导丝以使扩大的远端部分与导管轴的选择性阀装置的接合和分离的装置。 还提供了一种绞盘装置,通过该装置,引导线可以相对于导管轴旋转,以沿着血管通路转向导丝。 导管轴的远端锥形部分为导丝组件的接头提供保护。 导管的管状轴可以延伸穿过气囊以为导管提供更好的推动性,特别是在采用气囊相对较差的材料的形式中。 提出了用于导管轴的选择性阀装置和导丝组件的扩大的远端部分的几种替代结构。
