Title: GUIDE EXTENSION CATHETER WITH EXPANDABLE BALLOON
Abstract:
A guide extension catheter 514may include a proximal shaft 516 having a first outer diameter. A distal sheath 526 may be attached to the proximal shaft and may have a second outer diameter greater than the first outer diameter. The distal sheath may be designed to extend past a coronary ostium and into a coronary artery so that another medical device can pass therethrough toward the coronary artery. An expandable balloon 546 may be coupled to the distal sheath.
