摘要： An apparatus for deflecting a catheter or lead, for example a deflectable stylet or guidewire. The device includes an outer tubular member, a tension member mounted within the outer tubular member and coupled to the outer member and a handle mounted at the proximal end of the tubular member. The handle includes a major handle portion which has a rotatable knob located at its distal end, surrounding a proximal portion of the outer tubular member and provided with inwardly directed threading and an inner slider member provided with outwardly directed threading engaging the inwardly directed threading of the knob. The slider is advanced or retracted longitudinally within the handle by rotation of the knob but is rotationally fixed with regard to the major handle portion. The outer tubular member is engaged at its proximal end with the inner slider member and the tension wire is fixedly engaged with the major handle portion, whereby rotation of the knob results in advancement or retraction of the outer tubular member relative to the tension wire and the major portion of the handle, which in turn causes the deflection of the outer tubular member.

摘要： A transvenous lead introducer having a mechanical valve assembly disposed thereon. In a preferred embodiment, a longitudinally splittable introducer sheath is provided with a sliding valve at or near one end. The sliding valve may be spring-biased to a normally closed position. A semicircular notch may be provided in the forward end of the sliding valve, so that the sheath may be effectively sealed even when a guide wire runs through the sheath. In an alternative embodiment, the sliding valve is adapted to have its forward end inserted into a notch in the cylindrical sheath body. The mechanical valve assembly is further configured to permit use with a splittable lead introducer sheath.
摘要翻译：一种具有设置在其上的机械阀组件的静脉导管引导器。在优选实施例中，纵向可分开的导引套在其一端或附近设置有滑阀。滑动阀可以被弹簧偏压到常闭位置。可以在滑动阀的前端设置半圆形切口，使得即使当导丝穿过护套时也可以有效地密封护套。在替代实施例中，滑阀适于将其前端插入圆柱形护套主体中的凹口中。机械阀组件进一步构造成允许使用可分离的引导导管鞘。
