A method is disclosed. The method can comprise obtaining a first staple cartridge and obtaining a second staple cartridge, wherein the first staple cartridge and the second staple cartridge comprise the same length and the same width. The method can further comprise inserting the first staple cartridge into a channel comprising a keyed profile, wherein complete insertion of the first staple cartridge into the channel is prevented by the keyed profile. Additionally, the method can comprise inserting the second staple cartridge into the channel, wherein complete insertion of the second staple cartridge into the channel is permitted by the keyed profile.

A bariatric device includes an esophageal member having an esophageal surface that is configured to generally conform to the shape and size of a portion of the esophagus and an anchoring technique anchoring the esophageal member to the portion of the esophagus. The bariatric device includes a cardiac member having a cardiac surface that is configured to generally conform to the shape and size of a portion of the cardiac portion of the stomach and a connector connected with the esophageal member and the cardiac member to cause strain to be applied by the cardiac member to the cardiac portion of the stomach. The strain applied by the cardiac member to the cardiac portion of the stomach causes satiety in the absence of food. The connector is adapted to pass through the gastroesophageal junction while leaving a continuous portion of the gastroesophageal junction substantially unrestrained.

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

A method for controlling an operation of an ultrasonic blade of an ultrasonic electromechanical system is disclosed. The method includes providing an ultrasonic electromechanical system comprising an ultrasonic transducer coupled to an ultrasonic blade via an ultrasonic waveguide; applying, by an energy source, a power level to the ultrasonic transducer; determining, by a control circuit coupled to a memory, a mechanical property of the ultrasonic electromechanical system; comparing, by the control circuit, the mechanical property with a reference mechanical property stored in the memory; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the comparison of the mechanical property with the reference mechanical property.

Three-arm clamp includes: clamping assembly and releasing member connected to each other, clamping assembly includes fixed arm, and two movable arms respectively rotatably connected to fixed arm by hinge pin; the proximal end of each movable arm is provided with first sliding slot, and sliding pin is slidably arranged in first sliding slot; the proximal end of fixed arm is provided with inner cavity, and releasing member is inserted into inner cavity and connected to sliding pin; the proximal end of each movable arm is provided with elastic sheet; movable arms and fixed arm are closed by clamping, and elastic sheets are folded in inner cavity, in radial direction of fixed arm, from connecting end to free end and abut against releasing member; and releasing member is separated from movable arms, and the free end of each elastic sheet elastically abuts against inner wall of inner cavity.

A clipping system includes a cap, a clip and a control member. The cap includes a channel extending therethrough. A proximal portion of the cap is mounted over the endoscope such that a distal portion of the cap extends distally past a distal end of an endoscope. The distal portion of the channel includes opposing surfaces therealong defining a tapered portion tapering from the distal end of the cap toward a proximal end. The clip is mounted within the cap. The clip includes jaws movably connected via hinges. At least one of the hinges is biased to move the jaws away from one another. The clip is movable relative to the cap between open and closed configurations. The control member longitudinally movable relative to the cap to move the clip between the open and closed configurations.

A clipping system includes an adapter and a clip. The adapter is mounted over a distal end of an insertion device to a distal end and has a first annular groove formed in a distal face of the adapter. The clip has a body; a central body having a coupling portion and a ring; and jaws having outer arms coupled to the body at an outer arm proximal end and inner arms disposed radially inward of the outer arms and coupled to the ring at an inner arm proximal end. The body includes an annular protrusion extending proximally from a proximal surface of the body. The protrusion is inserted into the first groove of the adapter to couple the clip to the adapter. Movement of the central body along an axis of the clip causes movement of the jaws between an insertion configuration and a deployment configuration.

A system for treating tissue includes a cap mounted over a distal end of an endoscope, a clip mountable over the cap and including first and second jaws movably connected to one another between an insertion configuration, in which the first and second jaws extend over the cap to receive a target tissue therebetween, a review configuration, in which at least a portion of the clip extends into a field of view of the optical system of an endoscope, and a deployed configuration in which the clip is moved distally off of the cap so that the first and second jaws are drawn toward one another. A control element is configured so that movement proximally through the cap via a first distance moves the clip from the insertion configuration to the review configuration and a second distance moves the clip from the review configuration to the deployed configuration.

A surgical clamp may have two elongated members with a bight portion that joins the two elongated members at a proximal end of the clamp and that may bias the two elongated members in an open position at a distal end. The bight portion may have one or more engagement features, such as a slotted aperture or other engagement or coupling feature. A clasp mechanism at the distal end of the clamp may have a male or first component disposed on or adjacent one of the two elongated members and a female or second component disposed on or adjacent the other of the two elongated members at the distal end of the clamp.

A device includes an anoscope including an elongated hollow member with a longitudinal slot configured to receive tissue in an interior of the hollow member. The device also includes a clip applicator. The clip applicator includes a body slidably received in the slot and jaws at a distal end of the body configured to hold a ligation clip. The clip applicator further includes a plunger slidably coupled to the body configured to actuate the jaws. When the clip applicator is inserted into the slot and the plunger is moved relative to the body, the jaws close and deform the ligation clip from an open position into a closed position around tissue received in the slot.
