A surgical system includes a surgical instrument, including a shaft assembly having a distal end and an end effector at the distal end of the shaft assembly. The end effector includes a first jaw, a second jaw movably coupled relative to the first jaw for clamping tissue therebetween, and an optical sensor for detecting the tissue. The surgical system also includes a generator configured to supply a therapeutic energy to the first jaw or the second jaw, and a pass-through device configured to be connected between the surgical instrument and the generator. The pass-through device includes a therapeutic energy connector configured to operatively couple the generator to the surgical instrument for transmitting the therapeutic energy from the generator to the first jaw or the second jaw, and at least one optical component configured to transmit light to the optical sensor and to receive light from the optical sensor.

An apparatus for treating obesity comprises a volume filling device formed by at least two segments and is provided and following implantation, the device is placed resting against the stomach wall of the patient to reduce the inner volume of the stomach, thereby affecting the patients appetite.

The present invention is directed to a surgical instrument with a robotics system, a memory device and an end effector having an elongate channel, knife position sensor(s) and a firing bar coupled to a knife. In response to drive motions initiated by the robotics system, the firing bar may translate within the elongate channel. As the firing bar translates, the sensor(s) transmit a signal to the memory device. The position of the knife may be determined from the output signals and may be communicated to the robotics system or instrument user. The sensors may be Hall Effect sensors.

A system for non-invasively adjusting the curvature of a spine includes a housing having a first end and a second end, a first rod having a first end telescopically disposed within a cavity of the housing along a first longitudinal axis at the first end of the housing and having a first threaded portion extending thereon, and a second end configured to be coupled to a first portion of a spinal system of a subject, a second rod having a first end telescopically disposed within the cavity along a second longitudinal axis at the second end of the housing and having a second threaded portion extending thereon, and a second end configured to be coupled to a second portion of the spinal system of the subject, a driving member rotatably disposed within the cavity and configured to be activated from a location external to the body of the subject.

A surgical instrument. The surgical instrument includes an end effector that comprises a staple channel and an anvil that is movably translatable relative to the staple channel. A tool mounting portion is configured to interface with a robotic system and operably communicate with the end effector. The instrument further includes a first sensor that has an output that represents a first condition of a portion of the robotic system. A second sensor has an output that represents a position of the anvil. A third sensor has an output that represents a position of a reciprocating knife within the end effector. An externally accessible memory device communicates with the first, second and third sensors.

Systems and methods and devices are provided for treating conditions such as heart failure and/or pulmonary hypertension by at least partially occluding flow through the superior vena cava for an interval spanning multiple cardiac cycles. A catheter with an occlusion device is provided along with a controller that actuates a drive mechanism to provide at least partial occlusion of the patient's superior vena cava, which reduces cardiac filling pressures, and induces a favorable shift in the patient's Frank-Starling curve towards healthy heart functionality and improved cardiac performance. The occlusion device may include a lumen obstructed by a relief valve that may permit fluid flow through the occlusion device to release an excessive build-up of pressure.

There is provided a method for controlling the movement of bile and/or gall stones in the biliary duct. The method comprises gently constricting (i.e., without substantially hampering the blood circulation in the tissue wall) at least one portion of the tissue wall to influence the movement of bile and/or gallstones in the biliary duct, and stimulating the constricted wall portion to cause contraction of the wall portion to further influence the movement of bile and/or gallstones in the biliary duct. The method can be used for restricting or stopping the movement of bile and/or gallstones in the biliary duct, or for actively moving the fluid in the biliary duct, with a low risk of injuring the biliary duct.

A system for detecting an anastomotic leak includes a sensor assembly implanted at an anastomosis site. The system also includes a reader configured to receive sensor signals from the sensor assembly and a computing device configured to communicate with the reader. The computing device may be configured to analyze the sensor signals to determine a status of the anastomosis site.

Surgical devices and surgical systems are disclosed. The surgical device can comprise an actuator and a control circuit configured to adjust one or more functions of the surgical device based on a signal from a situationally-aware surgical hub. A surgical system can comprise a screen and a control circuit configured to communicate a priority level of a recommendation to the clinician on the display.

Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.
