Apparatus and method for loading and delivering a stent
First Claim
1. A stent loading and deployment device comprising:
- an outer elongate tubular member having opposed proximal and distal ends;
an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member, wherein, when the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between; and
a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member;
wherein the distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

Abstract
A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member.

27. A method for loading a stent into a delivery and deployment device, comprising
a. providing a radially distensible stent having opposed proximal and distal ends; -
b. providing a delivery deployment device, the device comprising; an outer elongate tubular member having opposed proximal and distal ends; an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member, wherein, when the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between; and a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member; c. axially moving or sliding the distal end of the stent loading member to a distal position past the distal end of the outer tubular member to releasably engage the stent; and d. axially moving or sliding the stent and the stent loading member toward the proximal end of the outer tubular member to radially compress the stent within the stent deployment region; - View Dependent Claims (28, 29, 30, 31, 32, 33, 34)
