F16L 37/00

US Classification:

285307, 285305, 285308, 604533

Abstract:

A female connector for releasable coupling with a male connector is disclosed herein. The male connector defines a fluid conduit and includes a male end adapted to be received within the female connector. The male end includes a coupling feature. The female connector comprises an opening, a collet finger, and an actuation element. The opening is adapted to guide the male connector along a first line of action as the male connector passes into the opening to be received within the female connector. The collet finger includes an engagement feature adapted to engage the coupling feature of the male end and displace along a second line of action generally normal to the first line of action. The actuation element is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male end. When the engagement feature is engaged with the coupling feature, the fluid conduit of the male connector is held in fluid communication with a fluid conduit of the female connector.

Abstract:

A latching female tubing coupler comprises an opening, a collet finger, and an actuation member. The opening is adapted to guide a male connector along a first line of action as the male connector passes into the opening to be received within the latching female tubing coupler. The collet finger includes an engagement feature adapted to engage a coupling feature of the male connector and displace along a second line of action generally normal to the first line of action. The actuator member is adapted to displace along a third line of action generally normal to the first and second lines of action in order to disengage the engagement feature from the coupling feature of the male connector. When the engagement feature is engaged with the coupling feature on a male connector, a fluid conduit of the male connector is held in fluid communication with a fluid conduit of the latching female tubing coupler.

Assignee:

TYCO Healthcare Group LP - Mansfield MA

International Classification:

A61B 18/10

US Classification:

606 34, 375238, 375239, 375295

Abstract:

An electrosurgical system is disclosed. The electrosurgical system includes an electrosurgical instrument configured to generate a first and second data streams and a transmission circuit configured to convert the first and second data streams into a pulsed transmission signal. The first signal property of the transmission signal is representative of the first data stream and the second signal property of the transmission signal is representative of the second data stream. The transmission circuit is further configured to process the transmission signal to decode the first signal property into the first data stream and the second signal property into the second data stream.

Appl. No.:

11/900474

Inventors:

Jeffrey L. Jensen - Boulder CO, US

International Classification:

A61B 18/12

US Classification:

606 41

Abstract:

A delivery apparatus for supporting an electrosurgical instrument and for connecting the electrosurgical instrument to an electrosurgical energy source is provided. The delivery apparatus includes a selectively positionable housing including a plurality of rigid segments and a joint member interposed between each adjacent rigid member; and a transmission medium extending through at least one of the segments of the housing. The transmission medium is configured to transmit electrosurgical energy between the electrosurgical energy source and the electrosurgical instrument. In use, the housing is movable between a first position wherein an electrosurgical instrument supported on an end of the housing is remote from an operative site and a second position wherein the electrosurgical instrument supported on the end of the housing is proximate to the operative site.

International Classification:

US Classification:

606 33

Abstract:

A microwave ablation system includes a generator operable to output energy and an ablation probe coupled to the generator that delivers the energy to a tissue region. The ablation system also includes a controller operable to control the generator and at least one sensor coupled to the ablation probe and the controller that detects an operating parameter of the ablation probe. The controller performs a system check by ramping up an energy output of the generator from a low energy level to a high energy level and monitors an output from the sensor at predetermined intervals of time during the system check to determine an abnormal state. The controller controls the generator to cease the energy output when the controller determines an abnormal state.
