An apparatus includes a shaft assembly, an end effector, and a drive member visualization assembly. The end effector includes a first jaw, a second jaw, a staple cartridge, and a drive member capable of actuating along a firing stroke to fire a plurality of staples out of the staple cartridge or to sever tissue. The drive member visualization assembly provides an electronic indication linked to a physical location of the drive member within the upper jaw and the lower jaw during the firing stroke.

An apparatus includes an end effector, a motor, and a processing unit. The processing unit is configured to activate the motor to distally advance a firing member within a body of the end effector. The processing unit is further configured to detect an initiation condition. In response to detecting the initiation condition, the processing unit is configured to activate an algorithmic bumping mode. The bumping mode includes activating the motor to advance the firing member distally with a first plurality starting and stopping motions at a first rate and a first power level. The bumping mode further includes activating the motor to retract the firing member proximally with a second plurality of starting and stopping motions at a second rate and a second power level. The first rate is different than the second rate. The first power level is different than the second power level.

A surgical instrument includes a body, a shaft assembly, an end effector, a stapling assembly, and a restriction feature. The shaft assembly extends distally from the body. The end effector being on a distal end of the shaft assembly and incudes a first second jaw. The stapling assembly is supported by one of the first jaw or the second jaw. The stapling assembly includes a wedge sled. The wedge sled is configured to move relative to the one of the first jaw or the second jaw to drive movement of one or more staples. The restriction feature is configured to releasably hold the wedge sled in a predetermined position within the stapling assembly while the stapling assembly is in a pre-fired configuration. At least a portion of the restriction feature is configured to respond to movement of the edge sled to release the restriction feature from the wedge sled.

Systems and methods for effecting bariatric procedures are disclosed. Each system includes an instrument, a control valve and, optionally, a suction controller. The instrument is in the form of an elongated, flexible member having a distal end portion arranged for anchoring the instrument in the patient's stomach and for enabling fluids to be removed from the patient's stomach. Suction is applied to the patient's stomach by the distal end portion of the instrument to drain gastric fluids and to bring adjacent portions of the patient's stomach into engagement with the instrument to provide a visually perceptible delineation line along which a portion of the stomach may be resected, sealed and tested.

A surgical stapling device (10) includes a reload assembly (300) having a cartridge assembly (100) and a shipping cap (200) releasably attached to the cartridge assembly (100). The cartridge assembly (100) includes an alignment pin assembly (140) having an alignment pin (144) defining a key hole slot (151) and is movable between a locked position and an unlocked position. The shipping cap (200) includes a locking pin (230) received through the key hole slot (151). When the alignment pin (144) is in the locked position, the alignment pin (144) prevents separation of the shipping cap (200) from the replaceable cartridge assembly (100) and when the alignment pin (144) is in the unlocked position, the alignment pin (144) permits separation of the shipping cap (200) from the replaceable cartridge assembly (100).
