摘要:
A guide extension catheter may include a proximal shaft and a tubular distal sheath including an exchange channel allowing for access (e.g. side access) into the lumen. Guide extension catheters may be used in conjunction with a guide catheter and a medical device having a distal region disposed within the guide catheter and a proximal region disposed outside of the guide catheter. A portion of the proximal region of the medical device can be passed through the exchange channel and into the lumen, and the guide extension catheter can be advanced into the guide catheter over the medical device without removing the medical device from the guide catheter. The exchange channel can extend in a straight line path along the sheath, or may extend in an indirect path along the sheath.
