Abstract
Abstract A method of fabricating a catheter shaft having one or more guidewire ports is disclosed. A method in accordance with the present invention includes the steps of cutting the wall of a first shaft portion to create an opening defined by the wall of the first shaft portion, inserting the proximal end of an inner member through the opening defined by the wall of the first shaft portion, inserting the distal end of the inner member into the lumen of a second shaft portion, inserting the bonding end the second shaft portion into a lumen defined by first shaft portion, and bonding the bonding portion of the first shaft portion to the bonding portion of the second shaft portion.
