    • A vascular access system for accurately locating body structures, such as blood vessels within a patient includes a flexible probe for applying Doppler ultrasonic techniques that has a relatively adjustable length relative to a needle assembly. The flexible probe has a coaxial cable design that includes a piezoelectric element at a proximal end of the probe. The piezoelectric element is used for emitting ultrasonic signals and for receiving ultrasonic signals that are reflected off of various body structures within a patient. The intensity of the reflective ultrasonic signals is used to determine the location of a preselected body structure. The flexible probe is adaptable for use within a variety of needles for a variety of applications.
    • 用于精确定位身体结构(例如患者内的血管)的血管通路系统包括用于施加相对于针组件具有相对可调节的长度的多普勒超声技术的柔性探针。 柔性探头具有同轴电缆设计,其包括位于探针近端的压电元件。 压电元件用于发射超声波信号并用于接收从患者体内各种身体结构反射的超声波信号。 反射超声波信号的强度用于确定预选体结构的位置。 柔性探头适用于各种针头,适用于各种应用。

    • Spinal stabilization devices, systems, and methods are described. Foramenal spacers including a rigid member adapted to maintain the integrity of the foramenal space. Facet joint stabilizing members and prosthetic facet joints that augment or replace the native facet joint are also described. Lateral spinal stabilization systems that may be attached to the lateral surfaces of adjacent vertebral bodies are described. Also described are anterior spinal stabilization systems that are to be attached to the anterior surfaces of adjacent vertebral bodies. Several variations of dynamic spinal stabilization devices and systems are described. Each of the foregoing devices, systems, and methods may be used independently, in combination with the other devices, systems, and methods described herein, and/or in combination with prosthetic intervertebral discs.
