Abstract
Apparatus and methods are provided for managing delivery of fluid into a vessel. A balloon catheter with a 3-way valve is introduced into an occluded vessel. The 3-way valve permits fluid, such as a contrast dye, to be injected into the vessel lumen. The valve is also configured to permit the balloon portion of the catheter to be inflated by means of the same lumen used to inject the contrast dye into the vessel. Bloodstream pressure can also be measured before and after dilation to confirm the procedure was successful. This apparatus and method provides for a quick, safe, and reliable treatment of an occluded vessel, among other things and works with known and later developed systems.
