Full thickness resectioning device
First Claim
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.

Abstract
A full thickness resection device comprises a control handle including an actuator wherein, when the device is in an operative position within a body lumen of a patient, the control handle remains outside the patient'"'"'s body and a working head assembly coupled to a control handle by a flexible sheath, wherein, when the device is in the operative position; the working head assembly is located within a body lumen of the patient adjacent to a portion of tissue to be treated, the working head assembly including a tissue stapling mechanism including first and second tissue stapling members moveable relative to one another in combination with 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.

9. A full thickness resection device comprising:
-
a control handle including an actuator wherein, when the device is in an operative position within a body lumen of a patient, the control handle remains outside the patient'"'"'s body;
a working head assembly coupled to the control handle wherein, when the device is in the operative position;
the working head assembly is located within a body lumen of the patient adjacent to a portion of tissue to be resected, the working head assembly including first and second tissue coupling members moveable relative to one another;
a flexible drive shaft extending from the actuator to the working head assembly; and
a first mounting bar coupled to the first tissue coupling member and movably received within the working head assembly, the first mounting bar being coupled to the drive shaft via a first threading so that, as the drive shaft is rotated relative to the first mounting bar, the first mounting bar and the first tissue coupling member move along a longitudinal axis of the drive shaft relative to the second tissue stapling member. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)
