Abstract
A perfusion balloon catheter, as for angioplasty, has the balloon formed so that, when inflated within a vas or coronary artery, one or more channels are provided for the flow of bodily fluids or blood past the inflated balloon. In one embodiment, the balloon has a toroidal shape which defines a central open channel. In another embodiment, the balloon defines a multiply-lobed form which allows flow between the lobes. Balloon catheters with open channels, when used for angioplasty, reduce the likelihood of early termination of the procedure due to chest pain.
