1. A system for removing occlusive material from vessels, the system comprising:
a catheter defining a lumen; and
a material removal device including:
a containing element including a distal opening and an outer wall portion, wherein the outer wall portion defines an expandable interior chamber; and
a distal control body extending through the distal opening,
wherein the distal control body is coupled to a distal portion of the containing element,
wherein the distal control body is configured to apply distally directed forces on the distal opening by translating the distal control body relative to the containing element,
wherein, when the material removal device is disposed within the catheter and a distal force is applied to the containing element by distally translating the distal control body, the containing element deploys from the catheter; and
wherein when the containing element is deployed from the catheter, applying a second distal force by distally translating the distal control body transitions the containing element into a collapsed configuration.
