    摘要： A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.

    摘要： An ultrasound imaging system includes an interventional medical device having a first tracking element that generates tip location data based on an EM locator field. An ultrasound probe has an ultrasound transducer mechanism and a second tracking element. The ultrasound transducer mechanism has an active ultrasound transducer array that generates two-dimensional ultrasound slice data at any of a plurality of discrete imaging locations within a three-dimensional imaging volume. The second tracking element generates probe location data based on the EM locator field. A processor circuit is configured to execute program instructions to generate an ultrasound image for display, and is configured to generate a positioning signal based on the tip location data and the probe location data to dynamically position the active ultrasound transducer array so that the two-dimensional ultrasound slice data includes the distal tip of the interventional medical device.

    摘要： A method of generating a 3D ultrasound image includes acquiring a 3D volumetric data set corresponding to a 3D imaging volume of an ultrasound probe in a 3D detection volume; acquiring a position of the ultrasound probe with respect to the 3D detection volume; acquiring a position of an interventional medical device with respect to the 3D detection volume; determining a position of the interventional medical device relative to the 3D imaging volume of the ultrasound probe; determining an interventional medical device-aligned plane that intersects with a longitudinal axis of the interventional medical device; extracting a texture slice from the 3D imaging volume for a corresponding interventional medical device-aligned plane positional and rotational orientation; mapping the texture slice onto the interventional medical device-aligned plane; and rendering the interventional medical device-aligned plane as a 3D ultrasound image and displaying the rendered 3D ultrasound image on a display screen.

    摘要： 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. In one embodiment, the insertion device comprises a body that includes 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 guides a needle of the needle assembly along a predetermined path such that the needle transcutaneously pierces a septum of the implanted access port.

    摘要： An access port for subcutaneous implantation into a body of a patient is disclosed. The port is typically subcutaneously connected to a catheter, a distal portion of which is disposed within a vein or other vessel of the patient. The port is configured with enhanced fluid handling features to improve fluid flow therethrough while reducing the likelihood of clotting or occlusions in the attached catheter, thus improving system patency. In one embodiment, for instance, an implantable access port is disclosed and comprises a body defining a reservoir, a needle-penetrable septum covering an opening to the reservoir, a stem defining an outlet to the reservoir, and a deformable element included in the reservoir. The deformable element is operably connected to a main portion of the septum and deforms in response to displacement of the septum to counteract a change in volume within the reservoir and prevent blood ingress into the catheter.

    摘要： 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.
