Patent number: 9368004Abstract: An assembly for use with a surgical device includes an enclosure defining a passageway extending from an interior to an exterior thereof and a visual indicator mounted within the interior of the enclosure adjacent the passageway. The visual indicator is configured to emit light. The passageway is partially defined by a concave surface of the enclosure and/or a chamfered portion of the enclosure to facilitate the passage of light emitted by the visual indicator through the passageway and to the exterior of the enclosure to increase the external viewing angle of the light emitted from the visual indicator.Type: GrantFiled: October 10, 2013Date of Patent: June 14, 2016Assignee: COVIDIEN LPInventor: Thomas Plaven

Patent number: 8944834Abstract: A universal contact port for receiving contacts of various cross-sectional dimensions and cross-sectional profiles of an electrosurgical component is provided. The universal contact port includes a plurality of rollers each defining a corporal axis, the corporal axes being at least substantially parallel to one another; and a plurality of shafts eccentrically supporting a respective roller, each shaft defining a longitudinal axis, wherein each corporal axis is spaced a radial distance from a respective longitudinal axis and wherein the rollers are rotatable about the longitudinal axes. The rollers define an opening therebetween, wherein the opening is expandable and constrictable upon rotation of the rollers about the longitudinal axes, whereby the contact port can accommodate receipt of contacts, from electrosurgical components, of varying cross-sectional diameter therein.Type: GrantFiled: September 8, 2011Date of Patent: February 3, 2015Assignee: Covidien AGInventors: Thomas Plaven, Robert L. Lohe

Patent number: 8025660Abstract: A universal contact port for use in an electrosurgical generator is provided and includes a ring gear having a circular rim formed therein and defines a central rotational axis. The rim includes a series of teeth formed therearound. A plurality of spur gears are operatively engaged with the rim of the ring gear, each spur gear defining a longitudinal axis which is at least substantially parallel with the central rotational axis; and a plurality of rollers operatively associated with a respective spur gear, each roller defining a corporal axis. The corporal axis of each roller is parallel to and spaced from the longitudinal axis of the respective spur gear. The rollers define an opening therebetween. The opening is constricted by rotation of the ring gear in a first direction about the central rotational axis and expanded by rotation of the ring gear in a direction opposite to the first direction.Type: GrantFiled: November 18, 2009Date of Patent: September 27, 2011Assignee: Covidien AGInventors: Thomas Plaven, Robert L.
