BULBOUS BALLOON WITH MECHANICAL PRESSURE REGULATOR |
摘要 |
A measuring balloon has an inner bulbous balloon formed from a non-compliant or semi-compliant material and has a central smaller diameter inner waist and two larger diameter bulbs on each side of the inner waist. A compliant outer waist bladder is located on the outside of the inner bulbous balloon adjacent to the inner waist and is inflated via a separate inflation lumen. The inner balloon is inflated at a higher pressure to dilate stenotic aortic valve leaflets, and provide alignment and positioning of the measuring balloon across the aortic annulus. The bladder waist is inflated to a lower pressure to make contact with the aortic valve annulus. Marker bands positioned on the outside of the measuring balloon provide determination of annulus diameter and ovality. |
