ABSTRACT:
A perfusion balloon catheter (10), as for angioplasty by dilatation, has the balloon (30) formed so that, when inflated within a vas or coronary artery, one or more channels (40) 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 order to avoid closure of the central channel when the balloon inflation pressure is increased to distend the vas within which it is placed, a portion (44) of the balloon is made from a relatively elastic membrane, and the portion of the balloon (244) adjacent the channel (40) is made from a relatively less elastic material, or a rigid material, whereby additional pressure does not cause channel closure.
