An electrosurgical aspiration instrument that permits aspiration of an area being treated by the instrument. The instrument is coupled at a proximal end to a power source and includes an energy application surface area at a distal end. The power source supplied energy to the energy application surface area such that the distal end of the instrument may apply energy to the treatment area to modify the characteristics of biological material, such as biological tissue in the area. An aspiration lumen is formed through the instrument with an opening through the energy application surface area. The energy application surface area is configured to reduce blockage of the opening. Accordingly, aspiration may be performed simultaneously with electrosurgical treatment whereby unwanted matter such as by-products, biological debris and excess fluid is removed from the treatment area. The electrosurgical aspiration instrument also permits both functions to be performed at different times, with the advantage of not requiring instruments to be switched on during the treatment procedure or removed from the treatment site.

Surgical instrument for ablation and aspiration

A stent or stent-graft deployment apparatus or mechanism configured so that, when activated, the stent or stent-graft progressively expands in a direction from its end which is proximally positioned to the deployment instrument, such as a percutaneous catheter, to its end which is distally positioned to the deployment instrument. The stent or stent-graft deployment mechanism includes a tether or slip line configuration which reduces the likelihood of snagging between the line and stent member. A method is also provided for deploying a stent or stent-graft within a mammalian lumen which includes expanding the stent or stent-graft in such a proximal-to-distal direction. The apparatus and method of the present invention minimize the likelihood of the stent or stent-graft from being displaced from the desired site before it is somewhat secured in the vessel during deployment.

Stent-graft deployment apparatus and method

Disclosed is a surgical apparatus including a surgical instrument including a housing and a cannula, and a surgical tool including a shaft and a tip, and a drive interface and an electrical interface, and the drive interface producing a surgical motion of the tip, and the electrical interface producing a cauterizing action of the tip. Also disclosed is a cutting and cauterizing device for connection to a surgical instrument. Additionally, methods for using both the surgical apparatus and the cutting and cauterizing device are disclosed.

Electrocauterizing tool for orthopedic shave devices

An electrosurgical electrode, comprising a metal conductor having a first external surface area and having a convex body, a flat face on the body, and a connector for attaching the body to an electrosurgical probe handle, and an insulating layer covering the first external surface of the metal conductor except at a selected second area of one of the convex body and the flat face, the second area being positioned on the metal conductor so that a line from a geometric center of the second area and substantially perpendicular to the second area intersects at an angle an axis formed by a probe handle and the metal conductor upon attachment of a probe handle to the connector, wherein the second area does not intersect the axis along the probe handle. Also disclosed are methods of manufacture and similar off-axis electrodes useful in endoscopic electrosurgery.

Electrode for electrosurgical coagulation of tissue

Disclosed is an integrated surgical and cauterizing apparatus, comprising a surgical instrument including a drive member, a cannula, and a tool, and the cannula attached at a proximal end to the drive member and defining at a distal end thereof an opening, and the tool including a shaft and a tip, and the shaft contained within he cannula and connecting the tip in the opening of the cannula to the drive member to produce a surgical motion of the tip; and a cauterizing instrument comprising at least one electrode, and a conductor, and at least one electrode affixed to the cannula adjacent to the distal end of the cannula and the conductor providing an electrical path from the at least one electrode for the application of electrical power to the at least one electrode to produce a cauterizing effect.
