Abstract

An insertable catheter device includes a shaft including a proximal end and a distal end, an expandable balloon, and an actuator configured to expand and retract the expandable balloon. The actuator includes a fluid conduit that extends through the shaft and is coupled with the expandable balloon to enable inflation and retraction of the expandable balloon via injection or withdrawal of a fluid to or from the expandable balloon via the fluid conduit. The expandable balloon is displaceably retractable into the shaft and extendable from the shaft. A fluid pump is coupled with the fluid conduit to pump the fluid through the fluid conduit. A patch is positioned to be displaced by the expandable balloon when the expandable balloon is inflated, and the expandable balloon is displaceably retractable into the shaft and displaceably extendable from the shaft.
