  • Publication number: 20190351136
    Abstract: An insertion device to assist in accessing an access port that has been subcutaneously implanted in the body of a patient is disclosed. The implanted access port is accessed by a needle of a needle assembly, such as a needle-based infusion set. The insertion device may include a body having a stabilizing portion and a guide portion. The stabilizing portion stabilizes a position of the implanted access port when the body is placed on the skin of the patient atop the implanted access port. The guide portion is designed to guide a needle of the needle assembly along a predetermined path such that the needle transcutaneously pierces a septum of the implanted access port.

  • Publication number: 20190099108
    Abstract: A catheter placement system includes a catheter assembly, an external ultrasound probe, a tip location sensor, and a console. The catheter assembly includes a catheter, a magnetic component producing a magnetic field, and an electrocardiogram (ECG) sensor designed to measure an intravascular ECG signal. The external ultrasound probe includes user input controls. The tip location sensor is configured to detect the magnetic field of the magnetic component when the catheter is disposed in the patient, the magnetic field providing magnetic field information for locating the magnetic component relative to the tip location sensor, and to receive the intravascular ECG signal from the ECG sensor. The console is coupled to the tip location sensor and includes a processor and a display. The display is configured to show an image from the external ultrasound probe, a graphical representation of the magnetic component, and successive ECG waveforms detected by the ECG sensor.

    Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to intravascular introduction of the catheter. The ultrasound probe includes user input controls for controlling use of the ultrasound probe in an ultrasound mode and use of the tip location sensor in a tip location mode. In another embodiment, ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart.

  • Publication number: 20180169389
    Abstract: 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.
