摘要:
A medical implant deployment tool and deployment method are disclosed. One aspect of the invention provides an implant system including an implant adapted for endovascular delivery and deployment; and a deployment tool adapted to deploy the implant, with the deployment tool having an actuation controller; a plurality of actuation elements adapted to apply forces to one or more implant deployment mechanisms and each adapted to extend along an actuation element path within a patient's vasculature; and an actuation element compensation mechanism adapted to compensate for differences in length between the actuation element paths. Another aspect of the invention provides a method of deploying an implant including the steps of endovascularly delivering an implant and implant deployment mechanisms to an implant site and applying an actuation force to the implant deployment mechanisms through actuation elements extending through the patient's vasculature while compensating for differences in length between actuation element path lengths to deploy the implant.
