  • Vascular sealing device
    Patent number: 5957952
    Abstract: A device for sealing an opening or puncture in the wall of a blood vessel or other percutaneous openings. The device includes a shaft section of a small diameter, with an expandable balloon and atraumatic tip at its distal end. The proximal end of the device has an inflation/deflation port which is utilized to inflate the balloon once it is in place within the blood vessel or other body cavity. The entire device is typically placed through a vascular sheath, which is used during invasive percutaneous vascular procedures. The balloon is inflated and withdrawn until it engages the inner surface of the blood vessel or body cavity. The sheath is withdrawn from within the blood vessel or other body cavity to the outside of the body. A fixation collar loaded onto the shaft of the device allows for securement in place, within the blood vessel or other body cavity.
