    This study shows that the indwelling transcutaneous vascular access device is easily implanted with negligible infection rates and good biocompatibility. The device demonstrated stability and adequate flow rates in canine models.

    Area of Science:

    • Biomaterials Science
    • Medical Device Engineering
    • Vascular Access

    Background:

    • Standard intravenous needles and catheters require skilled placement.
    • There is a need for reliable and safe vascular access devices for chronic or repeated use.

    Purpose of the Study:

    • To evaluate the safety, efficacy, and biocompatibility of an indwelling transcutaneous vascular access device.
    • To assess the infection rates, stability, and flow characteristics of the device in a canine model.

    Main Methods:

    • The device was implanted in canine subjects.
    • Infection rates, biocompatibility, device stability, flow rates, and signs of irritation or thrombosis were monitored.
    • Chronic flow and hemodialysis studies were conducted.

    Main Results:

    • The device was easily implantable with low infection rates and good biocompatibility.
    • Adequate flow rates were maintained for 10-21 days, with good device stability and no blood leakage.
    • Minimal pain or irritation was observed, with no thrombotic tendencies noted.

    Conclusions:

    • The indwelling transcutaneous vascular access device shows promise as a safe and effective option for vascular access.
    • Further improvements in materials and device-tubing connections are suggested for enhanced performance and patient comfort.
