Abstract:
1. An actuator system for a full thickness resection device including a control handle which remains outside a patient's body and a working head assembly coupled to the control handle by a flexible sheath which extends from the control handle into a body lumen of the patient via a naturally occurring orifice to a working head assembly coupled to a distal end thereof wherein, when the device is in an operative position, the working head assembly is located adjacent to a portion of tissue to be stapled, the working head assembly including a tissue stapling mechanism with first and second tissue stapling members moveable relative to one another, the actuator system comprising: an actuator mounted on the control handle; a first cable extending from the actuator through the flexible sheath to the first tissue stapling member so that, when the actuator is operated to draw the first cable proximally from the sheath, the first tissue stapling member is moved in a first direction relative to the second tissue stapling member; and a second cable extending from the first tissue stapling member to the control handle so that, when the second cable is drawn proximally from the sheath, the first tissue stapling member is moved relative to the second tissue stapling member in a second direction opposite to the first direction.
