Medical device

A method for positioning a guide wire in a medical device, the method comprising:

• positioning a proximal section of the guide wire exteriorly of a proximal section of a shaft of the medical device;
• positioning an intermediate section of the guide wire such that the intermediate section of the guide wire radially accesses an intermediate section of the shaft, wherein the intermediate section of the guide wire extends radially between an exterior of the shaft and an interior of the shaft through a discontinuity in the intermediate section of the shaft, wherein the discontinuity is in an outer sleeve of the shaft, wherein the interior of the shaft includes a guide wire channel extending through a core body of the shaft, the guide wire channel receiving the guide wire, and wherein the outer sleeve is fixedly attached to the core body such that an outer surface of the core body engages an inner surface of the outer sleeve;
• and
• positioning a distal section of the guide wire within a distal section of the shaft, wherein the distal section of the guide wire is routed through the guide wire channel between the discontinuity and a guide wire opening at a distal end of the shaft.

A method for positioning a guide wire in a medical device, the method comprising:

• positioning a proximal section of the guide wire exteriorly of a proximal section of a shaft of the medical device;
• positioning an intermediate section of the guide wire such that the intermediate section of the guide wire radially accesses an intermediate section of the shaft, wherein the intermediate section of the guide wire passes radially between an exterior of the shaft and an interior of the shaft through a slot in the intermediate section of the shaft, wherein the slot is in an outer sleeve of the shaft, wherein the interior of the shaft includes a guide wire channel extending through a core body of the shaft, the guide wire channel receiving the guide wire, and wherein the outer sleeve covers the core body;
• and
• positioning a distal section of the guide wire within a distal section of the shaft, wherein the distal section of the guide wire is routed through the guide wire channel between the slot and a guide wire opening at a distal end of the shaft, such that the distal section of the guide wire passes through an intermediate sleeve disposed radially between the outer sleeve and the core body, and wherein a proximal end of the intermediate sleeve terminates distally of a distal end of the slot, such that interference between the intermediate section of the guide wire and the intermediate sleeve is avoided.

A method for positioning a guide wire in a medical device, the method comprising:

• inserting the guide wire through an aperture of a channel in a shaft of the medical device, the channel defining a passageway between an outer surface of an outer sleeve of the shaft and a longitudinally-extending guide wire lumen within the shaft;
• engaging a moveable member of the shaft with the guide wire during insertion of the guide wire through the aperture, wherein the moveable member is configured to move between a first position and a second position, the moveable member being closer to the aperture in the first position than in the second position;
• and
• routing the guide wire through a portion of the guide wire lumen distal to the channel.
