INFLATABLE BALLOONS WITH FLOW CHANNELS

Abstract: the present disclosure relates to inflatable balloons designed to permit blood flow through channels formed along and optionally around their outer surfaces. such a balloon can include least two lobes spiraling around the balloon's axis and along the length of the central portion, and at least two depressed portions extending between the helical lobes. when the balloon is inflated within a target lumen, helical channels are provided between the depressed portions and an inner surface of the target lumen to allow blood to flow through the channels and across the balloon. the balloon can be inflated in a gradual manner, optionally based at least in part on measurements from one or more sensor(s) that can be attached to the balloon, such as flow sensors configured to measure flow through the helical channels, and/or force sensors configured to measure force applied against the balloon during inflation thereof.
