Insert for coupling sheaths used in medical devices

摘要

An insert for joining sheaths for use in a medical device is described. The insert has a first end including a first operative coupling and a second end including a second operative coupling. The first operative coupling is for engaging a first tube at its distal end, and the second operative coupling is for engaging a second tube at its proximal end. The insert also includes a first passageway extending through the insert from the second end to an exit port disposed between the first operative coupling and the second operative coupling. This disclosure also provides a catheter including such an insert, and a method of assembling a catheter.
