28. A catheter, comprising:
-
an outer sheath having a proximal end, a distal end, a side opening, and a lumen extending therethrough;
an inner member slidably disposed within the lumen of the outer sheath, said inner member including a tubular member having a proximal opening in communication with the side opening, a distal opening, a distal tip, and a lumen extending therethrough adapted to sidably receive a guidewire; and
wherein the inner member is actuatable between a first position and a second position relative to the outer sheath, said distal tip extending at least in part distally of the distal end of the outer sheath in the first position and a distance proximally of the distal end of the outer sheath in the second position. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42)

43. A catheter, comprising:
-
an outer sheath having a proximal end, a distal end, a side opening, and a lumen extending therethrough;
an inner member slidably disposed within the lumen of the outer sheath, said inner member having a proximal region including a lock wire, a distal region including a tubular member, and a mid-region coupling the lock wire to the tubular member;
the tubular member having a proximal opening in communication with the side opening, a distal opening, a distal tip, and a lumen extending theretrough adapted to slidably receive a guidewire; and
wherein the inner member is actuatable between a first position and a second position relative to the outer sheath, said distal tip extending at least in part distally of the distal end of the outer sheath in the first position and a distance proximally of the distal end of the outer sheath in the second position. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55)

56. A catheter, comprising:
-
an outer sheath having a proximal end, a distal end, a side opening, and a lumen extending therethrough;
an inner member slidably disposed within the lumen of the outer sheath, said inner member including a tubular member having a proximal opening in communication with the side opening, a distal opening, a distal tip, and a lumen therethrough adapted to slidably receive a guidewire;
wherein the inner member is actuatable between a first position and a second position relative to the outer sheath, said distal tip extending at least in part distally of the distal end of the outer sheath in the first position and a distance proximally of the distal end of the outer sheath in the second position; and
wherein the proximal opening of the tubular member remains in communication with the side opening of the outer sheath during said first and second positions.
