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 method includes cutting a septal wall between a right atrium and left atrium of a heart of a patient to form a multi-cuspid valvular shunt, and ablating septal wall tissue of at least a portion of the multi-cuspid valvular shunt to cause the ablated portion of the multi-cuspid valvular shunt to be biostable.

An endoscopy instrument is configured to be adjustable between a retracted position and an extended position. The endoscopy instrument includes a snare forming a loop extending from a proximate end to a distal end and a plurality of basket wires. Each of the basket wires includes a proximate end coupled to the proximate end of the snare and a distal end coupled to the distal end of the snare. The snare and the plurality of the basket wires cooperate to form a basket portion configured to contract when the endoscopy instrument is adjusted from the extended position towards the retracted position during entry of the basket portion into a tubular member. The contracting of the basket portion aids in grasping an object in need of retrieval from a patient.

A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaptation of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.

A device and method for diverting a portion of oxygenated blood from a lower pressure region, e.g., left atrium or pulmonary vein, and providing it to the aorta, bypassing the left ventricle, operating at least in part, on the Venturi effect. The device includes a first conduit that diverts a portion of blood from the aorta to a parallel flow path. The device includes a second conduit that delivers blood from the lower pressure region to the first conduit. The blood from the lower pressure region in the second conduit is combined with the blood from the aorta in the first conduit and returned to the aorta. The second conduit is coupled to the first conduit at or near a narrow segment of the first conduit. A Venturi effect at or near the narrow segment draws the blood from the lower pressure region into the first and/or second conduit.

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.

A system and associated method for altering or destroying tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders. In one aspect, the system includes a device configured to deploy devices for altering the lobes of a prostate.

This invention is directed to a medical device having an elongate shaft having a distal end and a controller coupled to the shaft. A control member can extend through at least part of the elongate shaft and at least part of the controller, wherein the control member in a tensioned configuration can be moveable by the controller to control the distal end of the shaft and the control member can be slack in an untensioned configuration. A tensioning mechanism can be configured to move relative to at least one of the elongate shaft and the controller to tension the control member and automatically lock the control member in the tensioned configuration.

A robotic surgical system may be used to perform a surgical procedure. Providing guidance for the robotic surgical system includes integrating a Point of View (PoV) surgical drill with a camera to capture a PoV image of a surgical area of a subject patient; displaying an image of the surgical area, based on a viewing angle of the PoV surgical drill, thus enabling the surgeon to operate on the surgical area using the PoV surgical drill. The PoV surgical drill operates based on the surgeon's control of a guidance drill. The content of the images may change based on a change in the viewing angle of the PoV surgical drill.

Various embodiments of tool assemblies are provided having at least one rotary input coupling and at least one linear input coupling for allowing either a rotary output or a linear output (e.g., from a tool driver on a surgical robot) to activate at least one mechanism of the tool assembly. For example, mechanisms of the tool assembly can include a clamping assembly, a firing assembly, an articulation assembly, and a roll assembly. The clamping assembly can open and close jaws of an end effector, the firing assembly can translate a knife assembly through the end effector to fire staples and cut tissue, the articulation assembly can articulate the end effector, and the roll assembly can rotate the elongate shaft and/or the end effector.
