Abstract
A system for delivering an expandable implant into the vasculature of a patient, including an elongated core element having a proximal end accessible exterior to the patient and a distal end including at least one feature for engaging a proximal portion of the implant in a collapsed state. The system further includes an expansion limiter having an inner diameter and a length sufficient to cover the proximal portion of the implant and to retain the proximal portion in the collapsed state, and at least one elongated member having a distal end connected to the expansion limiter and a proximal end accessible exterior to the patient to enable proximal movement of the expansion limiter to release the implant.
