    摘要： Transdermal insertion of a transcutaneous filling apparatus, for the purpose of filling a fill chamber of an implanted therapy delivery device, is monitored by measuring each impedance between pairs of electrodes of a needle of the apparatus, and comparing each to a threshold impedance; the electrodes, preferably at least three in number, are isolated and spaced apart from one another along a length of the needle. A confirmation signal is generated when at least one of the measured impedances is greater than the threshold impedance, and another is less than the threshold, the condition indicating that one of the electrodes is located within a non-conductive septum, through which the apparatus must pass to access the fill chamber. A detection circuit, which may be located in a housing of the apparatus that is attached to a proximal end of the needle, measures and compares the impedances.

    摘要翻译： 通过测量装置针的电极对之间的每个阻抗，并将每个阻抗与阈值阻抗进行比较来监测用于填充植入的治疗输送装置的填充室的经皮填充装置的经皮插入。 优选地，至少三个数量的电极沿着针的长度被隔离并彼此间隔开。 当所测量的阻抗中的至少一个大于阈值阻抗，另一个小于阈值时，产生确认信号，该条件指示电极中的一个位于非导电隔膜内，该装置必须通过该阻塞 通过进入填充室。 可以位于装置的外壳中的检测电路，其连接到针的近端，测量并比较阻抗。

    摘要： Generally described herein are an apparatus, a method of use, and/or a system related to an implant detector for detecting whether a needle inserted into a body of a patient has come into contact with a sensitive portion of the implanted gastric banding system (e.g., the tube connecting the access port to the gastric band). For example, a warning light may be activated. By alerting the medical professional when the inserted needle has come into contact with a sensitive portion of the implanted gastric banding system, the implant detector may prevent the medical professional from puncturing the contacted sensitive portion.

    摘要： Systems for detecting needle insertion into a port chamber of an implantable medical device include a pressure sensor. The system detects characteristic pressure profiles associated with needle insertion into the port chamber through a septum and may generate a sensory cue to a clinician that proper needle placement has been achieved. Methods for detecting needle insertion into a port chamber of an implantable medical device includes detecting characteristic pressure profiles associated with needle insertion into the port chamber through a septum.

    摘要： A vascular access port system including means for detecting and indicating the presence or absence of a needle. The detecting and indicating means may be carried in whole or in part by one of or both of the needle and/or the vascular access port. The detecting and indicating means may utilize a conductive needle, a mechanical switch, a magnetic switch, a Hall effect sensor, an electric field, a magnetic field, or an inductor, for example, for detection purposes. The vascular access port system permits the practitioner to confirm that the needle has been correctly inserted into the VAP, and notifies the patient and/or practitioner if the needle has been accidentally withdrawn.
