A surgical device which combines cautery and tissue debris conveyance via a combination of suction and an Archimedes screw, the cautery electrode encased within the Archimedes screw, the device comprising a device body housing a motor for rotating the screw, a cannula having an aperture for exposing an instrument, extending from the body portion, and a connector system operatively associated with the body portion, the connector system organized to provide pre-determined relative locations of connection for operably connecting the cannula, a cautery electrode and an Archimedes screw to the device body such the cautery electrode tip is positionable outside the aperture of the cannula and the Archimedes screw is disposed within the cannula in a position for conveying tissue entering the cannula via suction.

A tissue resecting device includes a housing having an outer shaft, the outer shaft including a tool portion disposed at a distal end thereof having a window defined therein with a proximal cutting edge. An inner shaft is disposed within the outer shaft and includes proximal and distal ends, the inner shaft configured to rotate upon actuation thereof. A cork-screw member extends distally from the distal end of the inner shaft and into the window. The cork-screw member is configured to rotate concomitantly with the inner shaft and includes a barb at a distal end thereof configured to pierce and retain tissue thereon. Upon rotation of the inner shaft, the barb pierces and retains tissue and withdraws tissue proximally along the cork-screw member and into the outer shaft and wherein excess tissue is excised by the proximal cutting edge of the window as the tissue is withdrawn through the outer shaft.

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 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.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

A medical device for removing an intravascular thrombus includes: a rotatable tubular driving shaft in which a spiral-shaped carrier is provided on an inner surface thereof; a cutting part that is provided on a distal side of the driving shaft and cuts the thrombus; and an elongated resistive body that is disposed in a lumen of the driving shaft and can be rotated relative to the driving shaft.

A surgical tool for use with a robotic system that includes a tool drive assembly that is operatively coupled to a control unit of the robotic system that is operable by inputs from an operator and is configured to robotically-generate output motions. A drive system is configured to interface with a corresponding portion of the tool drive assembly for receiving the robotically-generated output motions and applying the output motions to a drive shaft assembly which is configured to apply control motions to a surgical end effector operably coupled thereto. A manually-actuatable control system operably interfaces with the drive shaft assembly to facilitate the selective application of manually-generated control motions to the drive shaft assembly.

A method of removing embolic material from a vessel with mechanical and aspiration assistance. The method comprises the steps of providing an aspiration catheter having a central lumen and a distal end, advancing the distal end of the aspiration catheter to obstructive material in a vessel, applying vacuum to the central lumen to draw clot into the central lumen, introducing a thrombus engagement tool into the central lumen, and manually manipulating the tip to engage clot between the tip and an inside wall of the central lumen.

Systems and methods are disclosed including apparatuses and methods for endoscopy such as an endoscope device operable to produce suction. An endoscope can include or use a cylinder for use at a distal end of an endoscope, and the cylinder can include a cylinder channel extending from a first end of the cylinder to a second end of the cylinder, and a rotor arranged within a working channel of the endoscope at the distal end of the endoscope. The rotor can be movable within the cylinder or the channel such as to help fragment or clear foreign bodies during a procedure.

A thrombus engagement tool having a flexible shaft, a clot engagement tip, and a handle. The engagement tip may include one or more radially outwardly extending structures such as a helical thread. The helical thread can be advanced through a catheter to engage a clot. The handle may be configured to be rotated by hand. When the handle is rotated, the helical thread of the engagement tip can rotate in the same direction thereby allowing the helical threat to engage the clot. The helical thread can wrap around the flexible shaft at least about one, two, or four or more full revolutions, but in some cases no more than about ten or no more than about six revolutions.
