PHYSICIAN ACCESS SYSTEM

摘要

A physician access system comprising a catheter for use with an endoscope, the catheter including a wire guide lumen having a plurality of access ports disposed along an intermediate portion thereof to permit the insertion of a wire guide at different locations. The location of each access port corresponds to a specific length of the catheter exiting from the distal end of the endoscope. The access ports are located so that at least one of the access ports will be positioned near the endoscope handle when the distal end of the catheter, and any operational tool attached thereto, has been extended a short distance past the distal end of the endoscope. A physician may select the access port which best allows simultaneous control of the wire guide and the endoscope depending on the length of the catheter that the physician desires to have extend from the end of the endoscope.
