摘要： A stent includes a central portion of helically wound undulations formed of struts, cylindrical end portions, and transition zones between the helical portion and the cylindrical portions. According to a first aspect of the invention, the torsional flexibility of the stent is maximized by having bridges connecting adjacent winding be interrupted by the maximum possible number of undulations. In a preferred design, each winding includes nineteen undulations around the circumference, bridges are provided every five undulations. According to a second aspect of the invention, uniform opening of the transition zone is achieved by altering the width, and thereby the flexibility, of a series of struts in accordance with their lengths. Specifically, the long transition zone struts are made wider.

摘要： A biopsy forceps instrument is provided having a proximal actuation handle, a flexible multi-lumen tubular member, at least one control member extending through a lumen, an irrigation means, an aspiration means, and a distal assembly. The proximal actuation handle includes a shaft and a spool slidably mounted on the shaft. The actuation handle is coupled to the proximal ends of both the flexible tubular member and the control member. Lumens of the tubular member form irrigation and aspiration conduits. The distal assembly includes a hollow jaw cup coupled to the aspiration conduit and a hollow movable jaw coupled adjacent the irrigation conduit. The movable jaw is coupled to the control member, such that actuation of the actuation handle moves the movable jaw relative to the jaw cup. Moving the hollow jaws into a closed position provides a substantially fluidtight coupling between the irrigation and aspiration conduits. The actuation handle is also provided with an assembly to control irrigation to and aspiration from the distal assembly. A proximal sample chamber having a removable screen is provided for filtering tissue samples aspirated from the distal assembly. The jaws are activated to cut a tissue sample and the irrigation and aspiration means are activated to move the sample into the sample chamber for retrieving the sample without removing the instrument from a patient.

摘要： A non-metallic end effector for use in an endoscopic surgical tool includes a metallic core for strength and for providing a selected electrode surface on the end effector. Selectively conductive end effectors are manufactured by insert molding a plastic or ceramic or other non-conductive body around a metallic or otherwise conductive core. The conductive core is exposed on a selected portion of the working surface of the end effector and extends through the non-conductive body of the end effector for coupling to an electrical source. Selectively conductive end effectors of this type can also be manufactured by coating a cast end effector member with a non-conductive polymer or by metallically plating a non-conductive ceramic end effector member. By extending the conductive core of a selectively conductive end effector member to the pivot hole of the member, electrical coupling can be made through the clevis and tube of an endoscopic instrument. By extending the conductive core to the actuation bore of an end effector member, electrical coupling can be made through the push rod or other actuation member in an endoscopic instrument. Using both techniques, a bipolar selective cautery end effector can be provided on an endoscopic instrument.

摘要： An arthroscopic surgical instrument includes a hollow tube with an actuator coupled to its proximal end and an end effector coupled to its distal end. The actuator and the end effector are coupled by a cylindrical push rod which passes through the hollow tube. The push rod includes a frangible link in the form of a flattened portion with strength reducing semicircular side cuts which breaks when a predetermined force is applied to the end effector by the actuator. The end effector includes a stationary jaw and a movable jaw. The stationary jaw is coupled to the distal end of the tube and receives the push rod. The movable jaw is coupled to push rod and is pivotally coupled to the stationary jaw by arcuate engaging surfaces on both jaws. The movable jaw is also provided with a pair of serrated knife-like edges with an inner concave surface between them and the stationary jaw is provided with a receiving opening into which the movable jaw fits when the jaws are in a closed position. The receiving opening is defined by a pair of side walls having an upper taper which terminates in a sharp edge and a distal end wall having a concave inner surface. The concavity of the inner surface of the end wall is defined by a radius from the axis of rotation of the movable jaw. An electrical connection to the hollow tube is provided for supplying the jaws with a cautery current.

摘要： A flexible endoscopic clip applier includes a flexible coil with a manual actuator coupled to one end and a jaw assembly coupled to the other end. A store of clips is arranged adjacent to the jaw assembly and a clip pusher is arranged adjacent to the store of clips. The actuator includes a lever for opening and closing the jaws, a knob for rotating the jaw assembly, and a crank for dispensing clips. The knob and the lever are coupled to a single control member which extends through the coil to a joiner where it is joined to a pair of pull wires coupled to the jaws. The crank is coupled to a second control member which is threaded along a distal portion. The threaded portion engages a threaded member near the pusher and is coupled to the pusher such that rotation of the threaded control member by the crank causes the pusher to be moved distally.
