Stent crimping assembly and method
First Claim
1. A stent crimping assembly for crimping a stent from a first diameter to a reduced second diameter, said crimping assembly comprising:
- a set of two or more blade devices each having a proximal portion and a downstream distal portion, and a respective edge wall extending from the proximal portion to the distal portion, each respective edge wall being oriented relative to one another, in a respective crimp position, to collectively define an elongated conical-shaped crimp aperture, each edge wall tapering inwardly along a common longitudinal axis from the respective blade proximal portion toward the distal portion, the conical-shaped crimp aperture at the respective proximal portion of each blade being formed for receipt of at least a portion of the stent in the first diameter;
a drive assembly associated with each blade device and configured to independently displace each blade edge wall in a sequential manner substantially along a respective predetermined first path from the respective crimp position to a respective retracted position, oriented a predetermined incremental distance from said crimp position in a respective proximal direction.

Abstract
A stent crimping assembly is provided for crimping a stent from a first diameter to a reduced second diameter. The assembly includes a set of two or more blade devices each having a proximal portion, a downstream distal portion, and a respective edge wall extending from the proximal portion to the distal portion. Each respective edge wall is oriented relative to one another, in a respective crimp position, to collectively define an elongated conical-shaped crimp aperture. The conical-shaped crimp aperture at the respective proximal portion of each blade is formed for receipt of at least a portion of the stent in the first diameter. The crimping assembly further includes a drive assembly associated with each blade device and configured to independently displace each blade edge wall in a manner substantially along a respective predetermined first path from the respective crimp position to a respective retracted position, oriented a predetermined incremental distance from the crimp position in a respective proximal direction.

17. A stent crimping assembly for crimping a stent from a first diameter to a reduced second diameter, said crimping assembly comprising:
-
a set of two or more blade devices each having a first end and a second end, and a respective edge wall in opposed relationship to one another, each respective edge wall tapering inwardly from the respective one ends to the respective second ends, relative to a common longitudinal axis of an elongated crimp aperture collectively defined by the opposed edge walls in a respective crimp position, each said respective one ends collectively defining a receiving port into said crimp aperture formed for receipt of at least a portion of the stent in the first diameter; a respective drive assembly associated with each blade device and configured to sequentially displace each blade substantially along a respective predetermined path from the respective crimp position to a respective retracted position, oriented a predetermined incremental amount substantially along the common longitudinal axis of the crimp aperture and in a relative direction toward the respective one ends, sequentially diametrically reducing at least a portion of the stent from the first diameter to the reduced second diameter. - View Dependent Claims (18, 19, 20, 21, 22, 23)
