STENT DEVICE DELIVERY SYSTEM WITH A VARYING RADIAL PROFILE PULL MEMBER
First Claim
Patent Images
1. A stent device delivery system, comprising:
- a stent device; and
an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, the outer sheath is retractable relative to the stent device to allow radial expansion of the stent device to a deployed configuration, the outer sheath including a first layer and a reinforcement layer that are laminated together; and
a pull member attached to the outer sheath, a portion of the pull member captured radially between the first layer and the reinforcement layer, wherein at least a partial length of the portion of the pull member captured radially between the first layer and the reinforcement layer of the outer sheath is formed with a varying radial profile along said length.

Abstract
A stent device delivery system and method of making. The stent device delivery system includes a stent device, an outer sheath overlaying the stent device in a radially compact, delivery configuration of the stent device, and a pull member. The outer sheath may include a first layer and a reinforcement layer that are laminated together, a portion of the pull member captured radially between the first layer and the reinforcement layer. At least a partial length of the captured portion of the pull member may be formed with a varying radial profile.

20. A method of manufacturing a stent device delivery system comprising:
-
providing a stent device; providing an outer sheath to the stent device for retaining the stent device in a radially compact delivery configuration and being retractable relative to the stent device to allow radial expansion of the stent device to a deployed configuration; providing a pull member to the outer sheath; and laminating a reinforcement layer to the outer sheath to capture a portion of the pull member radially therebetween, wherein the pull member exhibits a varying radial profile along at least a portion of the captured length. - View Dependent Claims (21)
