Abstract
Abstract A stent delivery system for delivering a stent comprising, a stent disposed on the distal end of the catheter, and an inner core, wherein the inner core is resistant to appreciable compression or accordion. The catheter further comprising a first sheath covering a portion of the inner core, wherein at least a portion of the distal end of the inner core is left uncovered by the first sheath, a retractable sheath which covers at least a portion of the stent and a portion of the distal end of the inner core and a retracting means for retracting the distal sheath to release the stent.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
84 words
A retractable sheath for a stent delivery system comprising a tube of material made from tetrafluoroethylene fluorocarbon polymers or fluorinated ethylene-propylene resins and which is contoured with a pattern of grooves, the contoured sheath being made from the process comprising the steps of: placing the tube on a mandrel, wherein the diameter of the mandrel is slightly smaller than the inside diameter of the tube; winding a wire coil around the tube; heating the tube; cooling the tube; and removing the mandrel and coil.
Claim 2
Dependent Claim
84 words
A retractable sheath for a stent delivery system comprising a tube of material made from tetrafluoroethylene fluorocarbon polymers or fluorinated ethylene-propylene resins and which is contoured with a pattern of grooves, the contoured sheath being made from the process comprising the steps of: placing the tube on a mandrel, wherein the diameter of the mandrel is slightly smaller than the inside diameter of the tube; winding a wire coil around the tube; heating the tube; cooling the tube; and removing the mandrel and coil.
Claim 3
Independent Claim
68 words
A method of making a retractable sheath for a stent delivery system, comprising the steps of: placing a sheath made of material comprising tetrafluoroethylene fluorocarbon polymers or fluorinated ethylene-propylene resins on a mandrel, wherein the diameter of the mandrel is slightly smaller than the inside diameter of the sheath; winding a wire coil around the sheath; heating the sheath; cooling the sheath; and removing the mandrel and coil.
Claim 4
Independent Claim
68 words
A method of making a retractable sheath for a stent delivery system, comprising the steps of: placing a sheath made of material comprising tetrafluoroethylene fluorocarbon polymers or fluorinated ethylene-propylene resins on a mandrel, wherein the diameter of the mandrel is slightly smaller than the inside diameter of the sheath; winding a wire coil around the sheath; heating the sheath; cooling the sheath; and removing the mandrel and coil.
Claim 5
Dependent Claim
15 words
A method as in claim 2, wherein the wire coil is a cross-section wire coil.
Claim 6
Dependent Claim
15 words
A method as in claim 3, wherein the wire coil is a rectangular wire coil.
