Abstract
An inflatable balloon catheter having a guide wire lumen, an inflation lumen, and a one-way valve disposed within the inflation lumen, the one-way valve allowing fluid flow from the guide wire lumen into the inflation lumen and balloon. One method for preparing the catheter for use includes blocking the guide wire lumen proximal port and injecting inflation fluid into the guide wire lumen distal port. The injected fluid flows through the one-way valve into the inflation lumen and exits through the inflation lumen proximal port. One catheter includes a proximal switchable valve having bleed and inflation positions. This catheter provides a small distal profile and allows for bleeding the catheter while inflation equipment is attached to the catheter.
