1. A medical device delivery system comprising:
- an elongate tubular member comprising a circumferential wall and having first proximal and distal ends, the elongate tubular member defining a passageway extending between the first proximal and distal ends and having a protrusion disposed on an inner surface at the distal end;
a distal tip member slidably disposed within the first passageway and having proximal and distal portions, the proximal portion defining a mounting region;
a distal protection device disposed on the distal portion of the distal tip member; and
a self-expandable intraluminal medical device disposed on the mounting region of the distal tip member;
wherein the proximal portion includes second proximal and distal ends and the distal tip member includes a proximal flange disposed on the second proximal end and adapted to engage the protrusion;
further comprising a distal flange disposed on the second distal end, the distal flange adapted to temporarily engage the protrusion;
wherein the proximal and distal portions comprise separate members;
wherein the distal tip member further comprises a separable junction joining the proximal and distal portions; and
wherein the separable junction comprises at least one barb disposed on the distal portion and at least one cavity adapted to receive the at least one barb.
