An end effector for use to staple an anatomical structure of a patient during a surgical procedure includes an anvil and a cartridge. The anvil has an anvil face and a first staple pocket defined by the anvil face, where the first staple pocket comprises a first cup and a second cup for staple formation. The cartridge has a first staple and a first driver. The first staple, once deployed by the first driver and deformed by the first staple pocket, has a formed configuration in which a first portion of a first staple leg and a second portion of a second staple leg are bent relative to a crown and cross the midpoint of the crown and one of the first portion and the second portion overlaps the other of the first portion and the second portion.

Stapling systems and methods for surgical devices and end effectors

One or more medical devices may be provided that may be used, for example, in bariatric surgery including a vertical sleeve gastrectomy. Occlusion devices can be integrated with a catheter or tube to occlude one or more proximal or distal landmarks of a stomach and a stapling guide may be used to occlude a lateral boundary of the stomach to define a cavity. A volume of the potential resultant sleeve may be determined by inserting fluid or gas into the catheter or tube, measuring pressure, and calculating the volume of the cavity.

A system for preventing unwanted tissue migration in surgical staplers includes a surgical stapler having an end effector including an upper jaw and a lower jaw. A distal end of the upper jaw is connected to a distal end of the lower jaw, and a proximal end of the upper jaw is connected to a proximal end of the lower jaw. First and second tissue stops are formed on the distal and proximal ends of the lower jaw, respectively. The second tissue stop and the proximal end of the upper jaw define a no cut zone when the surgical stapler is in an open position. The surgical stapler also includes a tissue cutting device disposed within the lower jaw for resecting tissue. The system also includes a warning, blocking, impeding, or barrier forming device for preventing the unwanted migration of tissue into the no tissue zone.

Disclosed are embodiments of an apparatus, system, and method for performing a sleeve gastrectomy. The apparatus can include a bougie for insertion into an interior of a stomach, the bougie having a proximal bougie end and a distal bougie end, an inflation lumen having a proximal lumen end and a distal lumen end, the inflation lumen extending from the proximal bougie end through the distal bougie end, a fluid delivery system coupled with the proximal lumen end, the fluid delivery system being operably configured to deliver positive pressure in a predetermined positive pressure range into the stomach, and a monitor coupled with the proximal lumen end operably configured for the monitoring of pressure or volume within the stomach. The bougie can be operably configured to define a resection line for the sleeve gastrectomy when the predetermined positive pressure range is achieved within the stomach.

Systems and methods for reducing insufflation loss due to gas leakage during a laparoscopic surgical procedure are provided. The surgical procedure includes the use of a surgical instrument having an end effector and a trocar through which the surgical instrument is inserted for access to the abdominal cavity of a patient receiving laparoscopic surgery. The trocar includes a lip, a lip seal disposed within the lip, and a cannula located beneath the lip. The systems and methods reduce or prevent a loss of insufflation when using conventional systems and methods to insert the surgical instrument through a conventional trocar.

An end effector for use by a surgeon to staple an anatomical structure of a patient during a minimally invasive procedure can include an anvil, a cartridge, and a knife. The anvil includes a proximal end, a distal end, and a face that is positionable on a first side of the anatomical structure. The cartridge is configured to house a plurality of staples and includes a proximal end, a distal end, and a face that is positionable on a second side of the anatomical structure. The knife has a cutting edge, the knife being operably configured to move from a first position at about a distal end of the end effector to a second position at about a proximal end of the end effector. The distal end of the anvil is movably coupled to the distal end of the cartridge.

Embodiments include an end effector including an anvil, the anvil having an anvil face, a cartridge having a cartridge face, the cartridge being configured to retain a plurality of staples, a cord, and a buttress being coupled with the anvil face or the cartridge face and including a planar section of material and a plurality of loops extending laterally from a first side and a second side of the planar section of material, wherein at least one of the anvil or the cartridge includes a plurality of cord supports.
