Abstract
An apparatus for introducing an implant into a hollow anatomical structure. The apparatus comprises a storage unit having an exit opening and defining a chamber in communication with the exit opening; an elongate, self-expanding vascular implant having an expanded condition and stored within the chamber in the expanded condition, proximal of the exit opening; and a pushrod having a distal end aligned with and proximal of the exit opening. The pushrod is pre-assembled to a distal end of the implant. Associated methods, and other apparatus and methods, are also disclosed.

An apparatus for introducing an implant into a hollow anatomical structure, the apparatus comprising:
- a storage unit having an exit opening and defining a chamber in communication with the exit opening;
- an elongate, self-expanding vascular implant having an expanded condition and stored within the chamber in the expanded condition, proximal of the exit opening;
- and
- a pushrod having a distal end aligned with and proximal of the exit opening;
- wherein the pushrod is pre-assembled to a distal end of the implant.
An apparatus for introducing an implant into a hollow anatomical structure, the apparatus comprising:
- a storage unit having an exit opening and defining a chamber in communication with the exit opening;
- an elongate vascular implant having a first configuration in which the implant is larger than the exit opening and a second configuration in which the implant is smaller than the exit opening;
- and
- a pushrod having a distal end aligned with and proximal of the exit opening;
- wherein the pushrod is pre-assembled to a distal end of the implant and the implant is stored within the chamber in the first configuration and proximal of the exit opening.
A method for introducing an implant into a hollow anatomical structure, the method comprising:
- inserting an introducer sheath into the hollow anatomical structure;
- coupling a delivery apparatus to a proximal end of the introducer sheath, the delivery apparatus storing a vascular implant in an expanded condition, proximally of an exit opening of the delivery apparatus;
- and
- compressing the implant to a size sufficient to fit through the exit opening while distally advancing the implant through the exit opening and into the introducer sheath.
