Abstract
A balloon catheter comprises a tip having a tapered distal end, a central lumen, and a balloon membrane coaxial with and surrounding the central lumen and connected to the tip. A sheath is slidable over the balloon to form an assembly, and a guide wire is slidable through the central lumen and insertable into a blood vessel for guiding the tip, membrane and sheath to a location within the blood vessel selected for therapy. The sheath fits loosely over the balloon, whereby the sheath can be withdrawn to expose the balloon at the selected location and the balloon can then be inflated to provide therapy.
