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.

Systems and methods for measuring volume of potential sleeve in a sleeve gastrectomy

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.

Systems and methods for preventing tissue migration in surgical staplers

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 of performing surgery using laplace's law tension retraction during surgery

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

End effector coupling arrangements for a surgical cutting and stapling instrument

Devices and systems are provided for controlling movement of a working end of a surgical device by means of a robotic system. In one embodiment, systems and devices are provided for moving an end effector on a distal end of a surgical fastening device. Movement can include rotational movement of the end effector about an axis of the shaft, articulation of the end effector relative to the shaft, and actuation of an end effector, e.g., closing, firing, and/or cutting.

Robotically-controlled surgical instrument with selectively articulatable end effector

A staple having a crown, a deformable leg extending from the crown, and a spring extending from the crown configured to compress tissue between the spring and the deformable member. Owing to the flexibility of the spring, the staple can accommodate a wide range of tissue thicknesses while still compressing the tissue captured therein. As a result, a single staple design can be used in a wide variety of surgical procedures thereby reducing the amount of staple designs that must be provided to the surgeon. In at least one embodiment, the staple includes a crushable member. This crushable member can include a plastically deformable first portion and an elastically deformable second portion. The present invention can also include, in various embodiments, a crown, a first deformable member extending from the crown, and means for compressing the tissue against the first deformable member.

Surgical staples having compressible or crushable members for securing tissue therein and stapling instruments for deploying the same

An apparatus includes a body and a pair of rigid legs extending from the body. The body includes an engagement feature configured to engage a deployment instrument. The legs are parallel with each other. Each leg has a sharp tip. The legs both extend along a plane. The body defines a guide opening. The guide opening is oriented transversely relative to the plane associated with the legs. The guide opening is sized to receive a cannula having a generally flat profile. The guide opening is configured to guide the cannula through a sclerotomy at a substantially tangential orientation.

Guide apparatus for tangential entry into suprachoroidal space

Disclosed are embodiments of an apparatus and system 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 of performing surgery using Laplace's law tension retraction during surgery

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.
