Abstract
A medical implant delivery system maintains an orientation between a guidewire lumen of an inner member of the system and a rapid-exchange port in an outer member. The medical device is disposed intermediate the inner and outer members and in friction or pressure-fit contact with the outer member. Once the guidewire lumen of the inner member and the rapid exchange port of the outer member are oriented, the friction or pressure-fit operates to maintain the orientation until deployment of the medical implant. Orientation is further maintained by a telescoping coupling of the guide wire lumen with the rapid exchange port.

23. A system for performing a surgical procedure comprising:
-
an outer tubular member including a guidewire port extending radially therethrough; an inner tubular member slidably disposed within the outer tubular member, the inner tubular member including a lumen extending therethrough configured and dimensioned to receive a guidewire; a guidewire lumen extension extending proximally from the inner tubular member, the guidewire lumen extension being configured and dimensioned to receive the guidewire, and being in general alignment with the guidewire port extending radially through the outer tubular member; and an expandable implant connected to the inner tubular member movable between a contracted configuration and an expanded configuration, the implant being in frictional contact with an inner surface of the outer tubular member to rotationally fix the implant and the inner tubular member relative to the outer tubular member and thereby maintain rotational alignment between the guidewire lumen extension and the guidewire port extending radially through the outer tubular member. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)

37. A method of assembling an expandable implant and a delivery system configured and dimensioned to deploy the expandable implant, the method comprising:
-
positioning the implant about an inner member of the delivery system with the implant in a contracted state, the inner member including a guidewire lumen extension extending proximally therefrom; connecting the implant to the inner member; sliding an outer member of the delivery system distally relative to the inner member to cover a proximal end of the implant, the outer member including an extension extending inwardly into a lumen of the outer member; and expanding the implant within the outer member to cause frictional engagement between the implant and an inner surface of the outer member to inhibit relative rotation between the inner and outer members and thereby maintain rotational alignment between the guidewire lumen extension of the inner member and the extension of the outer member. - View Dependent Claims (38, 39, 40, 41, 42)
