  • Patent number: 4341218
    Abstract: A detachable balloon catheter for easy placement in arterial lesions. The detachable balloon catheter is comprised of a balloon having a hollow cylinder securely fastened at the neck or entrance to the balloon. A catheter tube is held inside the cylinder by a releasable retainer which permits atraumatic detachment of the catheter tube after placement of the balloon in a lesion. A seal means is installed inside the balloon for sealing the balloon after its placement and inflation. The releasable retainer permits atraumatic detachment by complete separation of the catheter tube from the balloon and its withdrawal after placement of the balloon without any force being applied to the arterial lesion.
