    摘要： A biopsy instrument and method of using such are provided wherein the biopsy instrument includes a proximal actuation handle, an elongate flexible member, and a distal assembly. The flexible member, connected to and extending from the actuation handle, includes an aspiration conduit for fluid connection with a vacuum source and for permitting the flow of fluid from the distal end to the proximal end of the biopsy instrument. The flexible member may include an irrigation conduit for supplying irrigation fluid to the distal end. The actuation handle includes a stationary member and an actuation device, and may include a sample chamber, a sample collector, valves for regulating the vacuum in the aspiration conduit and the fluid flow in the irrigation conduit, and a pressure increasing device for selectively increasing the pressure of the fluid supplied to the distal end. The distal assembly, coupled to the distal end of the flexible member, may be comprised of a movable jaw and a stationary jaw, or of first and second movable jaws. With the jaws in a closed position, the distal assembly may provide a substantially fluidtight passageway at the distal end of the aspiration conduit. The movable jaws are coupled to the actuation device, such that actuation of the actuation handle moves the movable jaws relative to the flexible member, thereby opening and closing the distal assembly.

    摘要： A preferred apparatus for delivering an intravascular drug such as a sclerosing agent (or a microfoam sclerosing agent) to a varicose vein includes a catheter having three concentric tubes. The innermost tube has a guide wire lumen and an inflation lumen. The distal end of the innermost tube has an integral inflatable occlusion balloon in fluid communication with the inflation lumen. The intermediate tube has a lumen through which the innermost tube extends. The distal end of the intermediate tube has a self-expanding balloon with a plurality of fluid pores in fluid communication with the intermediate tube lumen. The outer tube has a lumen through which the intermediate tube extends. Sclerosing agent is dispensed through the intermediate tube to pores located at the distal end of the intermediate tube or in the self-expanding balloon. Veins are sclerosed as the self-expanding balloon is pulled through and ultimately out of the vein.

    摘要： A bipolar push rod assembly is disclosed in conjunction with an endoscopic bipolar cautery scissors instrument. The push rod assembly has two conductive push rods which are substantially covered and insulated from each other by a double lumen flexible sheath. The proximal ends of the push rods are stabilized by an overmolded plastic collar and the distal ends of the push rods are stabilized by a ceramic insulator. The plastic collar is provided with a snap retainer for coupling it to a plastic plug retainer having a pair of spaced apart passages. A pair of female plug adapters are press fit onto the proximal ends of the push rods and are maintained in place by the plug retainer with each adaptor residing in a respective one of the passages. The distal ends of the push rods are swaged approximately 90.degree. in opposite directions. A ceramic insulator is disclosed as a one-piece unit into which the distal ends of the push rods are inserted. Another ceramic insulator is disclosed as a two-piece member which fits around the distal ends of the push rods. A double lumen sealing gasket which interrupts the double lumen sheath is also disclosed.
