Occlusion balloon catheter with external inflation lumen
First Claim
Patent Images
1. A balloon catheter having a distal region and a proximal region, comprising:
- an elongate shaft extending from the distal region to the proximal region and defining a working lumen therebetween, the elongate shaft having an inner and an outer surface;
an inflatable compliant balloon disposed about a portion of the distal region of the outer surface of the elongate shaft such that the shaft extends through the balloon; and
an external inflation component having an inflation lumen in fluid communication with the balloon;
wherein the external inflation component is disposed longitudinally along the outer surface of the elongate shaft.

Abstract
Catheters such as guide catheters can be configured to provide distal occlusion, while still providing sufficient interior lumen space for device delivery. Such catheters can also provide a desired level of flexibility, yet can include sufficient column support. A catheter can include an elongate shaft with a lumen, an inflatable compliant balloon disposed over the distal region of the shaft, and an external inflation component.
