A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.

Surgical stapler with timer and feedback display

A surgical stapling apparatus includes a staple cartridge and an anvil member. The staple cartridge includes a plurality of surgical fasteners disposed in rows of retention slots. The staple cartridge may have an annular or linear configuration of retention slots. The tissue contacting surface of the staple cartridge may be tapered or stepped. The anvil member has a tissue contacting surface that includes a number of pockets arranged for substantially aligning with the retention slots. In addition, the tissue contacting surface of the anvil member may complement the tissue contacting surface of the staple cartridge.

Surgical stapling instruments including a cartridge having multiple staples sizes

Surgical instruments are disclosed that are couplable to or have an end effector or a disposable loading unit with an end effector, and at least one micro-electromechanical system (MEMS) device operatively connected to the surgical instrument for at least one of sensing a condition, measuring a parameter and controlling the condition and/or parameter.

Surgical instruments including MEMS devices

An ultrasonic surgical instrument is provided which includes a handle assembly, a body extending distally from the handle assembly and an end effector configured to effect cutting, dissection, coagulation and/or ligation of tissue. The end effector includes an ultrasonic member. A transducer is supported adjacent, on or within the ultrasonic member and is connected to a power source. Upon actuation of the power source, the transducer effects vibration of the ultrasonic member. In one preferred embodiment, the end effector is mounted for articulation about the distal end of the instrument.

Ultrasonic surgical instrument

The present disclosure is directed to devices for approximating body vessels and method for performing the same. In accordance with one aspect of the present disclosure, the device includes an inner member having a first expandable anchor operatively coupled near a distal end thereof, an outer member having a second expandable anchor, and a sleeve disposed about at least a portion of the inner member and the outer member.

Methods and apparatus for anastomosis including expandable anchor

A staple is provided having a backspan and a first and second legs extending distally from the backspan. Each of the first and second legs includes a bend dividing each leg into a traversing leg portion and a substantially linear clenching leg portion. A staple plate is positionable over the first and second legs between the backspan and the first and second clenching leg portions. An anvil assembly has first and second movable members which move toward to one another to engage outer surfaces of the first and second clenching leg portions. There is further disclosed a method of forming the staple through tissue.
