Abstract: A grooved slider forming part of an electrode for use with a resectoscope is shown. The electrode includes an electrode lead member having an elongated conductor member. The elongated conductor member has a first end and a second end with an insulative cover extended therebetween. The first end has a protruding electrode adapted to be electrically connected to an electrosurgical generator and the second end terminates in an active member. An electrode support member is operatively connected to the active member. The electrode support member has an elongated semi-rigid bifurcated arm terminating in a conductive core spaced a predetermined distance from the active member. The bifurcated arm is covered with an insulative material except at the distal end where the grooved slider is located.

Abstract: A retrieval basket is provided for use with a surgical device adapted to capture calculi. The retrieval basket includes wires extending from a proximal end to a distal end of the basket wherein the wires converge at the proximal and distal ends. The wires in a proximal portion of the retrieval basket incline radially at an angle away from the basket's axis along relatively straight paths. The wires in a distal portion of the retrieval basket converge radially toward the axis along relatively curvilinear paths.
Abstract: A deflection cover for a medical endoscope comprises a tubular covering that protects the articulation system of an endoscope during sterilization procedures where pressure differentials are generated. The deflection cover is of a single layer of a selected material whose properties provide the deflection cover with adequate flexibility, thinness, and strength for use on a medical endoscope. The deflection cover may include a reinforcement structure, such as a helically oriented thread, to increase the tube's pressure resistance without impeding the tube's longitudinal flexibility, which is needed to allow the articulation system in the endoscope to deflect through its intended range of motion.
Abstract: A new and distinctive New Guinea Impatiens plant characterized by flowers with two or more colors distributed in distinct irregular randomly distributed patterns on some or all petals and flowers. The patterns are defined by multiple irregularly shaped regions of color. Generally, each region consists of an elongate streak or patch of color typically radiating in a direction from the base of a petal to the edge of the petal. The irregularly shaped regions, while not necessarily exclusive of other colors, generally are dominated by a single color. The streaks or patches forming regions may vary in color intensity, shape, length, and width. They also vary in terms of their position relative to the base and edge of a petal.
