Delivery system for medical devices
First Claim
1. A system for deploying a medical device, comprising:
- a handle assembly;
an inner catheter assembly operatively associated with the handle assembly, the inner catheter assembly including an inner catheter member coaxially arranged within a restraining member;
a self-expanding stent carried on the inner catheter member and maintained in a delivery position by the restraining member;
an outer assembly configured about the inner catheter assembly; and
a strain relief connecting the handle assembly to the outer assembly, the strain relief including a channel defining a maze-like thread;
wherein the strain relief is detachably connected to the handle assembly.

Abstract
The invention is directed a delivery system for implantation a self-expanding medical device in a body which includes a control handle and a catheter portion. The catheter portion includes an outer restraining member which covers the collapsed, medical device, an inner catheter member having a distal end including a region upon which the medical device is mounted, and an outer sheath which is removably attached to the control handle. The outer sheath creates a conduit for the catheter portion to prevent the inner catheter member from moving axially when the outer restraining member is retracted. The control handle has a rotatable thumbwheel to actuate a retraction mechanism attached to the proximal end of the outer restraining member which moves the restraining member in a proximal direction to deploy the medical device.
