WIRE COLLECTION DEVICE WITH INCREASING COLLECTION DIAMETER
First Claim
1. A stent deployment system, including a wire collection device comprising:
- a profiled retraction wire comprising a distal end coupled to a sledge and a proximal end coupled to a collection spindle, the sledge coupled to a proximal end of an outer sheath comprising a distal end surrounding a stent;
an actuator coupled to the collection spindle and operable to actuate rotation of the collection spindle to collect the profiled retraction wire around the collection spindle, wherein collection of the profiled retraction wire retracts the outer sheath across an outer surface of the stent so as to deploy the stent; and
a varying collection diameter that comprises a diameter of the collection spindle and a combined thickness of collected portions of the profiled retraction wire.

Abstract
A stent deployment system includes a wire collection device with a profiled retraction wire and an actuator coupled to a collection spindle. A distal end of the profiled retraction wire is coupled to a sledge that is coupled to an outer sheath. A proximal end of the profiled retraction wire is coupled to the collection spindle. The actuator can actuate rotation of the collection spindle to collect the profiled retraction wire around the collection spindle, and collection of the profiled retraction wire retracts the outer sheath across an outer surface of the stent so as to deploy a stent surrounded by a distal end of the outer sheath. The wire collection device has a varying collection diameter that includes the diameter of the collection spindle and the combined thickness of collected portions of the profiled retraction wire.

13. A stent deployment system, including a wire collection device comprising:
-
a profiled retraction wire coupled to an outer sheath to retract the outer sheath to deploy a stent from a distal end of the outer sheath, the profiled retraction wire comprising a thickness that increases from a proximal end attached to a collection spindle towards a distal end coupled to a proximal end of the outer sheath; and a thumbwheel coupled to the collection spindle and operable to actuate rotation of the collection spindle to collect the profiled retraction wire around a collection diameter that comprises the diameter of the collection spindle and the thickness of the retraction wire, wherein the collection diameter increases as the profiled retraction wire is collected around the collection spindle. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
