1. A method of forming a constraining mechanism for an implantable medical device delivery, the method comprising:
reducing a diameter of the implantable medical device from a deployed diameter to a reduced diameter by forcing the implantable medical device through a funnel having internal surfaces reducing in diameter; and
wrapping one or more fibers circumferentially about the implantable medical device and the funnel, wherein the funnel includes a zone defining a landing position for the one or more fibers when forming the constraining mechanism, the zone having a length approximately equal to a length of the implantable medical device; and
interlocking the one or more fibers on the implantable medical device along a length of the implantable medical device while the implantable medical device is constrained by the funnel in the reduced diameter to form the constraining mechanism.
