1. A body conduit lengthening and anastomosis creation device, comprising:
a tensioning assembly including a tension sensor coupled to a motor;
an extension sheath releasably coupled to and extending distally from the tensioning assembly, the extension sheath defining an extension sheath lumen therethrough;
a catheter coupled to the tension sensor, the catheter slidably disposed within the extension sheath lumen and defining an inflation lumen;
a flexible sheath having a proximal end portion that is releasably connected to a distal end portion of the extension sheath, the flexible sheath defining a flexible sheath lumen therethrough that is in fluid communication with the extension sheath lumen, the catheter slidably disposed within the flexible sheath lumen; and
an inflatable balloon member attached to a distal end portion of the catheter and in fluid communication with the inflation lumen of the catheter,
wherein the tensioning assembly is configured to pull the catheter proximally in relation to the flexible sheath when the motor is actuated.
