Stent loading and delivery device having a loading basket lock mechanism
First Claim
1. A stent loading and delivery system, the delivery system comprising:
- an inner elongate tubular member having a proximal end and a distal end;
an intermediate elongate tubular member having a proximal end and a distal end, the intermediate elongate tubular member surrounding the inner elongate tubular member and longitudinally slidable relative to the inner elongate tubular member;
an outer elongate tubular member having a proximal end and a distal end, the outer elongate tubular member surrounding the intermediate elongate tubular member and longitudinally slidable relative to both the inner elongate tubular member and the intermediate elongate tubular member;
the proximal end of the outer elongate tubular member movable distally relative to the intermediate elongate tubular member from a first proximal position to a distal position, and then movable proximally relative to the intermediate elongate tubular member from the distal position to a second proximal position, the second proximal position located distal of the first proximal position; and
a stop disposed on the intermediate elongate tubular member;
the stop movable between a first configuration when the proximal end of the outer elongate tubular member is in the first proximal position to a second configuration when the proximal end of the outer elongate tubular member is moved to the distal position, and wherein the stop prevents movement of the proximal end of the outer tubular member back to the first proximal position from the distal position.

Abstract
A stent loading and delivery system, the delivery system comprising an inner elongate tubular member having a proximal end and a distal end, an intermediate elongate tubular member having a proximal end and a distal end in sliding relationship to said inner elongate tubular member and an external elongate tubular member having a proximal end and a distal end in sliding relationship to said intermediate elongate tubular member, said intermediate elongate tubular member comprising a stop mechanism at its proximal end, wherein the stop mechanism prevents the external elongate tubular member from being slid past the stop mechanism when the external elongate tubular member is slid in a proximal direction.
