Abstract
Rapid exchange catheters with interlocking transition interfaces are disclosed. An example catheter includes an elongate body having a distal end portion carrying an interventional element thereon and a proximal end portion. The elongate body includes a distal shaft having a receptacle and a proximal shaft having a semi-tubular portion that is inserted into the distal shaft receptacle. The semi-tubular portion includes an engagement feature that limits movement of the semi-tubular portion with respect to the distal shaft receptacle. The catheter further includes an exchange port along an intermediate portion of the elongate body, and a guidewire lumen extending from the exchange port to the distal end portion of the elongate body.
