When in the expanded condition, the balloon has a centre line which follows a substantially helical path.
Claims24
An expandable balloon for insertion in a vessel of the human or animal body, the balloon being movable between a collapsed condition and an expanded condition, the balloon comprising a plaque disrupting formation arranged to be on an outer surface of the balloon when in the expanded condition, and the balloon having, when in the expanded condition, a centre line which follows a substantially helical path.
An expandable balloon for insertion in a vessel of the human or animal body, the balloon being movable between a collapsed condition and an expanded condition, the balloon having, when in the expanded condition, a centre line which follows a substantially helical path, and the balloon comprising hoop wires extending circumferentially of the balloon when in the expanded condition, the hoop wires being spaced apart from each other in the lengthwise direction of the balloon.
A method of treating a plaque in a vessel of the human or animal body, the method comprising deploying a balloon in a collapsed condition to a treatment site and expanding the balloon, the balloon comprising a plaque disrupting formation on an outer surface thereof, so that when the balloon is in the expanded condition the plaque disrupting formation exerts pressure on the plaque, and the balloon having, when in the expanded condition, a centreline which follows a substantially helical path.
