Abstract
Abstract The method for mounting an intravascular stent on the distal end of a catheter. The stent-loading device includes at least two substantially flat surfaces, that are parallel to each other, and that have relative sliding movement while remaining parallel. A stent is placed on the distal end of a catheter and positioned between the substantially flat surfaces which are then moved in an orthogonal direction relative to each other while simultaneous compressive force is applied to the stent. The stent is progressively crimped onto the catheter.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
58 words
A method of affixing an intravascular stent onto a catheter, comprising: placing an intravascular stent onto a catheter, placing the portion of said catheter containing said stent between two substantially flat surfaces, providing relative sliding movement between said two substantially flat surfaces and simultaneously imparting compressive forces on said stent to removably attach said stent onto the catheter.
Claim 2
Independent Claim
58 words
A method of affixing an intravascular stent onto a catheter, comprising: placing an intravascular stent onto a catheter, placing the portion of said catheter containing said stent between two substantially flat surfaces, providing relative sliding movement between said two substantially flat surfaces and simultaneously imparting compressive forces on said stent to removably attach said stent onto the catheter.
Claim 3
Dependent Claim
26 words
The method of affixing an intravascular stent onto a catheter according to claim 1, wherein said two substantially flat surfaces are slidably moved along two directions.
Claim 4
Dependent Claim
27 words
The method of affixing an intravascular stent onto a catheter according to claim 2, wherein said two substantially flat surfaces are moved along two substantially orthogonal directions.
Claim 5
Dependent Claim
30 words
The method of affixing an intravascular stent onto a catheter according to claim 1, further comprising measuring and displaying said compressive force applied to compress said stent onto said catheter.
Claim 6
Dependent Claim
49 words
The method of affixing an intravascular stent onto a catheter according to claim 1, wherein said step of providing relative sliding movement between said two substantially flat surfaces includes the step of providing movement of one of said substantially flat surfaces while maintaining the other substantially flat surface stationary.
Claim 7
Dependent Claim
30 words
The method of affixing an intravascular stent onto a catheter according to claim 1, wherein said two substantially flat surfaces remain substantially parallel while mounting said stent on said catheter.
