    摘要： A stylet capable of being at least partially disposed within a lumen of a device is disclosed. This stylet may include an elongated body comprising a proximal end, a distal end, and at least one magnetic material. In certain embodiments, the elongated body may also include at least one core element, a tubular member circumferentially disposed about at least a portion of the core element, and/or at least one support member circumferentially disposed about at least a portion of the core element. In addition, a matrix material may be disposed between the core element and the tubular member to retain the magnetic material within the elongated body. A catheter assembly including a stylet and a corresponding method of manufacture are also disclosed.

    摘要： A shaped guidewire for use in medical applications is disclosed. The guidewire is shaped so as to prevent inadvertent advancement of the guidewire into the corpus of a patient during use. In one embodiment, the guidewire includes an elongate body that defines proximal and distal ends. The guidewire body further defines a shaped portion that is positioned intermediate the proximal and distal ends. The shaped portion of the guidewire is at least partially composed of a shape memory material, such as nitinol, and is deflected from a longitudinal axis defined by an undeflected portion of the guidewire body. The shaped portion is disposed in one embodiment at the proximal end of the guidewire. In another embodiment, a proximal portion of the nitinol guidewire can be treated to impart malleability and enable deflection by a clinician. Methods for forming the shaped or malleable guidewire to include a deflected portion are disclosed.

    摘要： A needle guide assembly for inserting a needle into the body of a patient in order to access a subcutaneous target, such as a vessel, is disclosed. In one embodiment, the needle guide assembly comprises a needle guide body that is configured to at least indirectly and removably attach to an image producing device, such as an ultrasound probe. The needle guide body defines at least first and second elongate guide channels. Each guide channel defines a unique insertion angle with respect to a longitudinal axis of the ultrasound probe. Further, each guide channel is configured to accept needles of differing gauges.

    摘要： A stylet for use in guiding a distal tip of a catheter to a predetermined location within the body of a patient. In one embodiment the stylet is configured for use within a lumen of the catheter and comprises a core wire, an ECG sensor, and a magnetic assembly. The ECG sensor senses an ECG signal of a patient when the stylet is disposed within the lumen of the catheter and the catheter is disposed within the body of the patient. The magnetic assembly includes at least one element capable of producing a magnetic or electromagnetic field for detection by a sensor external to the patient. In another embodiment, the stylet includes a pre-shaped distal segment that is deflected with respect to a more proximal portion of the stylet, which in turn causes a distal segment of the catheter to be deflected when the stylet is received within the lumen.
