1. A system for treating a patient, the system comprising:
a catheter;
at least one retention element slidably disposed within the catheter;
an embolic material flowable or slidable through a lumen of the catheter; and
a pushrod comprising an elongate body slidably disposed within the catheter;
wherein the system is configured such that when the catheter is positioned in a body lumen and the catheter is retracted relative to the pushrod or the pushrod is advanced relative to the catheter, the at least one retention element and the embolic material are delivered from the catheter into the body lumen;
wherein the at least one retention element is configured to move from an unexpanded configuration to an expanded configuration within the body lumen and retain the embolic material substantially proximal to the at least one retention element within the body lumen; and
wherein the retention member is configured to be released and remain in the body with the embolic material.
