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, and an external elongate tubular member having a proximal end and a distal end, the external 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, said intermediate elongate tubular member comprising a stop mechanism disposed proximal of the distal end of the intermediate elongate tubular member and disposed about a circumference of the intermediate elongate tubular member, the stop mechanism having an unexpanded state and an expanded state, the stop mechanism in the expanded state prevents the external elongate tubular member permanently from moving in a proximal direction to a point beyond the stop mechanism.

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.

14. A stent loading and delivery system comprising:
-
an inner elongate tubular member having a proximal end and a distal end, the inner elongate tubular member having a proximal handle at the proximal end of the inner elongate tubular member; an intermediate elongate tubular member surrounding the inner elongate tubular member and longitudinally slidable relative to the inner elongate tubular member, the intermediate elongate tubular member having a proximal end and a distal end, the intermediate elongate tubular member having an intermediate handle, the intermediate handle having a first position and a second position, in the second position the intermediate handle is adjacent the proximal handle; an external elongate tubular member having a proximal end and a distal end, the external 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 external elongate tubular member having a distal handle at the proximal end of the elongate external tubular member, the distal handle having a proximal position and a distal position; and a stop mechanism disposed about a circumference of the intermediate elongate tubular member and proximal of the distal end of the intermediate elongate tubular member at a point corresponding to the proximal position of the distal handle of the external elongate tubular member, the stop mechanism having an unexpanded state and an expanded state; wherein when the distal handle of the external elongate tubular member is in the proximal position, the proximal end of the external elongate tubular member overlies the stop mechanism and the stop mechanism is in its unexpanded state, and when the distal handle of the external elongate tubular member is in the distal position, the stop mechanism is exposed and is in its expanded state, wherein the stop mechanism in its expanded state prevents the distal handle and external elongate tubular member permanently from moving proximally to a point beyond the stop mechanism. - View Dependent Claims (15, 16, 17, 18, 19, 20)
