Abstract: A control apparatus for use in conjunction with a lighted, hand held, surgical electrode holder and any electrosurgical current generator normally intended to function with a non-lighted, hand held surgical electrode holder, that permits delivery of illuminating current to the lighted holder's lamp, while simultaneously permitting on a selective basis, cutting current or coagulation current to pass through the holder's active electrode. In addition, the control apparatus provides the lamp with a delay shut-off which thereby permits a surgeon to inspect the site of surgery, either before or following surgery, when cutting or coagulation current does not flow.

Abstract: A blood clot filtration device, for implantation percutaneously, for preventing movement of blood clots within a blood vessel. The device has a head and a plurality of legs extending therefrom. The legs include a first linear leg portion of predetermined length emanating distally from the head generally parallel to the axis of the device; a second multi-angled leg portion of relatively greater length extending generally outwardly from the distal end of the first linear leg portion at an acute angle to the axis, to form, with other second leg portions, a conical aspect, the second leg portion having a series of discrete linear segments arrayed generally tangent to a cone defined by the second leg portions of the set of legs; and a hook portion at the distal end of each the leg extending outwardly, away from the axis in a manner for engaging the blood vessel to fix the position of the device therewithin.

Abstract: A gastro-enterostomy device consists of an introducing catheter, stiffening member, and separable conical tip for providing an introduction lumen of relatively large bore.

Abstract: A hand held holder, incorporating a light transmitting electrode tip that's separable from the handle, for use in high frequency electrosurgery, with built-in, finger actuated switches for operating a high frequency current generator. The device is particularly characterized in that in conjunction with a light transmitting electrode, it provides localized illumination at the region of surgery. To provide this illumination, an elongate photoconductive device is provided which extends generally longitudinally within the electrode, and communicates in the holder with a light transmitting portion, in the form of either a section of a strand like photoconductor, or an electrically operated lamp.
