A system for partitioning a patient's ventricle, the system comprising: an implant configured for deployment into the patient's ventricle, the implant including: a plurality of struts, wherein the implant is configured to have a collapsed delivery configuration and an expanded deployed configuration, and a strand extending between the struts, wherein the strand may be tensioned to collapse the struts; and an elongate applicator configured to insert the implant and retrieve the implant after the implant has been fully deployed, the applicator including: a control at the proximal end of the applicator for controlling release of the implant from the applicator, an implant stabilization shaft extending distally from the proximal end, wherein the implant stabilization shaft is configured to releasably secure to the implant, and a strand capture element extending distally from the proximal end, wherein the strand capture element is configured to engage the strand on the implant and collapse the struts of the implant, wherein the implant stabilization shaft is configured to operate independently of the strand capture element to engage and hold the fully deployed implant distally while the strand capture element draws the strand proximally to disengage the struts from the heart wall and collapse the implant. an implant configured for deployment into the patient's ventricle, the implant including: a plurality of struts, wherein the implant is configured to have a collapsed delivery configuration and an expanded deployed configuration, and a strand extending between the struts, wherein the strand may be tensioned to collapse the struts; and a plurality of struts, wherein the implant is configured to have a collapsed delivery configuration and an expanded deployed configuration, and a strand extending between the struts, wherein the strand may be tensioned to collapse the struts; and an elongate applicator configured to insert the implant and retrieve the implant after the implant has been fully deployed, the applicator including: a control at the proximal end of the applicator for controlling release of the implant from the applicator, an implant stabilization shaft extending distally from the proximal end, wherein the implant stabilization shaft is configured to releasably secure to the implant, and a strand capture element extending distally from the proximal end, wherein the strand capture element is configured to engage the strand on the implant and collapse the struts of the implant, wherein the implant stabilization shaft is configured to operate independently of the strand capture element to engage and hold the fully deployed implant distally while the strand capture element draws the strand proximally to disengage the struts from the heart wall and collapse the implant. a control at the proximal end of the applicator for controlling release of the implant from the applicator, an implant stabilization shaft extending distally from the proximal end, wherein the implant stabilization shaft is configured to releasably secure to the implant, and a strand capture element extending distally from the proximal end, wherein the strand capture element is configured to engage the strand on the implant and collapse the struts of the implant, wherein the implant stabilization shaft is configured to operate independently of the strand capture element to engage and hold the fully deployed implant distally while the strand capture element draws the strand proximally to disengage the struts from the heart wall and collapse the implant.
