First Claim
Patent Images
1. An instrument for use in modifying a patient'"'"'s stomach by operating on the stomach extragastrically to decrease the effective volume of the patient'"'"'s stomach, said instrument comprising:
- a first elongate end effector formed at a distal end portion of said instrument, said first elongate end effector having a first operational surface configured to contact an external surface of the patient'"'"'s stomach;
a second elongate end effector formed at a distal end portion of said instrument, said second elongate end effector having a second operational surface configured to contact an external surface of the patient'"'"'s stomach on a location opposite of where the first elongate end effector is configured to contact the external surface of the stomach, and wherein said second operational surface opposes said first operational surface;
a first plurality of suction ports extending along a length of said first elongate end effector from a distal portion of said first end effector to a proximal portion of said first end effector and configured to deliver suction to the external surface of the stomach to engage said first elongate end effector therewith; and
a second plurality of suction ports extending along a length of said second elongate end effector from a distal portion of said second end effector to a proximal portion of said second end effector and configured to deliver suction to the external surface of the stomach to engage said second elongate end effector therewith and wherein said first end effector and said second end effector are movable by actuating a joint mechanism connecting said first and second end effectors.

Abstract
Methods, instruments and systems are provided for separating opposite walls of the stomach by extragastric application of suction. Plication of the stomach can be performed between the separated walls after which the separate walls are brought back toward one another. In another aspect, methods, instruments, devices and systems are provided for reducing the effective volume of a stomach by performing one or more extragastric plications of the stomach.

13. A system for use in modifying a patient'"'"'s stomach by operating on the stomach extragastrically to decrease the effective volume of the patient'"'"'s stomach, said system comprising:
-
an engagement instrument comprising; a first elongate end effector at a distal end portion of said engagement instrument, said first elongate end effector having a first operational surface configured to contact an external surface of the patient'"'"'s stomach; a second elongate end effector at a distal end portion of said engagement instrument, said second elongate end effector having a second operational surface configured to contact an external surface of the patient'"'"'s stomach on a location opposite of where the first elongate end effector is configured to contact the external surface of the stomach, and wherein said second operational surface opposes said first operational surface; a first plurality of suction ports extending along a length of said first elongate end effector and configured to deliver suction to the external surface of the stomach to engage said first elongate end effector therewith; and a second plurality of suction ports extending along a length of said second elongate end effector and configured to deliver suction to the external surface of the stomach to engage said second elongate end effector therewith; and a stitching instrument comprising; a third end effector at a distal end portion of said stitching instrument, said third end effector having a third operational surface configured to contact an external surface of the patient'"'"'s stomach; a fourth end effector at a distal end portion of said stitching instrument, said fourth end effector having a fourth operational surface configured to contact an external surface of the patient'"'"'s stomach on a location opposite of where the third end effector is configured to contact the external surface of the stomach, and wherein said fourth operational surface opposes said third operational surface; at least one suture driver on the third end effector; and at least one suture anchor on said fourth end effector opposing said suture driver. - View Dependent Claims (14, 15)
