System and method for deploying and positioning an endovascular device

摘要

A dilator tip (100) for deploying and positioning an endovascular device (570) at a treatment site includes an elongate body (105) having at least two substantially longitudinal channels (110) in an outer surface (105s) of the body and at least two deployment struts (115). Each deployment strut (115) has a free end (120) releasably attached to a proximal edge (575) of an endovascular device (570) to be deployed, a constrained end (125) restrained within one of the longitudinal channels (110), and a pivot portion (130) between the free end (120) and the constrained end (125). In an undeployed configuration of the dilator tip (100), the free ends (120) reside within the longitudinal channels (110), and in a deployed configuration of the dilator tip (100), the free ends (120) are pivotally extended away from the longitudinal channels (110) by way of the pivot portions (130).

1. A dilator tip for deploying and positioning an endovascular device at a treatment site in a body vessel, including:
an elongate body including at least two substantially longitudinal channels in an outer surface of the body; at least two deployment struts, each deployment strut having a free end comprising a distal loop for releaseable attachment to a proximal edge of an endovascular device to be deployed, a constrained end restrained within one of the longitudinal channels, and a pivot portion between the free end and the constrained end; where, in an undeployed configuration of the dilator tip, the free ends reside within the longitudinal channels, and where, in a deployed configuration of the dilator tip, the free ends are pivotally extended away from the longitudinal channels by way of the pivot portions.
