  • Intravascular balloon catheter for embolic coil delivery
    Patent number: 6527790
    Abstract: Improved intravascular balloon catheters for the delivery of embolic agents and devices such as coils to wide-neck aneurysms. In one embodiment, the present invention provides a balloon catheter having a combined guide wire/delivery lumen and a lateral delivery hole. The balloon may comprise a multi-lobed design with the delivery hole disposed between adjacent balloon lobes. The balloon catheter preferably includes a diversion member disposed in the combined lumen to cause the embolic device to divert from the combined lumen, through the delivery hole, and into the wide-neck aneurysm. In another embodiment, the present invention provides a balloon catheter having a shaft including a shaft tube and a co-extending embolic delivery tube. The delivery tube terminates proximal of the distal end of the shaft tube for added flexibility, and the balloon may inflate eccentrically to push the distal opening of the delivery lumen adjacent the opening of the wide-neck aneurysm.
