Abstract
The disclosure pertains to a medical device deployment system comprising a restraint member which holds the embolic protection filter in a restrained, or partially collapsed, state for insertion into a lumen and transit to a desired deployment site. The restraint member comprises two or more portions which differ in their mechanical ability to resist the radial forces exerted by various portions of the medical device when it is in a restrained, or partially collapsed, state. The restraint member is maintained in a restraint configuration by an actuation member which engages portions of the restraint member lying on opposite sides of a generally axial gap until deployment of the medical device is desired. Withdrawal of the actuation member allows the restraint member to release the medical device which may then return to a deployed state. The invention also provides a method for assembling a medical device deployment system.
