A tissue segmentation device, controller, and methods therefore are disclosed. The device has an active electrode, a return electrode, a mechanical force application mechanism, voltage and current sensors, and a controller. The controller has a processing component, configured to assign a circuit status to a circuit comprising the at least one electrode. IF (PF≈0) and ((Vrms/Irms)≥T), THEN the circuit status is 'open'. IF (PF≈0) and ((Vrms/Irms)<T), THEN the circuit status is “short”. PF is a power factor of power applied to the electrosurgical device. T is a threshold value.

Electrosurgical device and methods

A coupling system and related methods are disclosed. The system has a first plug detachably coupled to a first housing, and a first socket detachably coupled to a second housing. The first socket is configured to receive the first plug. The system is movable between a first configuration wherein the first and second housings are not engaged and a second configuration wherein the first and second housings are engaged and the first plug and the first socket are coupled together.

Connector

A method and device for detecting leaks of a containment barrier. The method may comprise placing the barrier in contact with one or more volumes of fluid such that the one or more volumes of fluid is in contact with a first surface and a second surface of the containment barrier, then placing a first electrode in contact with a first volume of fluid within in a first area defined by the first surface of the containment barrier. The method may then comprise placing a second electrode in contact with a second volume of fluid in a second area defined by the second surface of the containment barrier, measuring electrical conductivity between the first and second electrodes; and determining a presence of a leak in the containment barrier based on a calculation using properties of the one or more volumes of fluid, the containment barrier, and the measured electrical conductivity.

Tissue specimen removal device, system and method

A tissue segmentation device, controller, and methods therefore are disclosed. The device has an active electrode, a return electrode, a mechanical force application mechanism, voltage and current sensors, and a controller. The controller has a processing component, configured to assign a circuit status to a circuit comprising the at least one electrode. IF (PF&#x2248;0) and ((Vrms/Irms)&#x2265;T), THEN the circuit status is 'open'. IF (PF&#x2248;0) and ((Vrms/Irms)&#x3c;T), THEN the circuit status is 'short'. PF is a power factor of power applied to the electrosurgical device. T is a threshold value.

A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.

A tissue removal system for extracting a tissue specimen from a patient and a related method are disclosed. The system has a flexible container with an opening associated with a proximal end, and a distal end. The system also has a plurality of wires removably coupled to an interior of the flexible container in a pre-collection configuration wherein the plurality of wires form a receiving space for receiving the tissue specimen and wherein the plurality of wires are positioned in a pattern. The pattern is selected to divide the tissue specimen into at least four pieces in response to at least one pulling force on the plurality of wires.

Large volume tissue reduction and removal system and method

A controller for an electrosurgical device and related methods and devices are disclosed. The controller has a processing component to: (a) derive a power factor of power applied to the electrosurgical device; and (b) responsive to the deriving a power factor, assign a circuit status to a circuit comprising the electrosurgical device. IF (PF&#x2248;0) and ((Vrms/Irms)&#x2265;T), THEN the circuit status is 'open'. IF (PF&#x2248;0) and ((Vrms/Irms)&#x3c;T), THEN the circuit status is 'short'. PF is the power factor. Vrms is the root mean square of a voltage associated with the power applied to the at electrosurgical device. Irms is the root mean square of a current associated with the power applied to the electrosurgical device. T is a threshold value.

A tissue segmentation device, controller, and methods therefore are disclosed. The device has an active electrode, a return electrode, a mechanical force application mechanism, voltage and current sensors, and a controller. The controller is configured to control a power output of the segmentation device. The controller has a processing component, responsive to the sensors, configured to execute the following: (a) derive a power factor of power applied to the at least one electrode; and (b) responsive to the deriving a power factor, assign a circuit status to a circuit comprising the at least one electrode. IF (PF&#x2248;0) and ((Vrms/Irms)&#x2267;T), THEN the circuit status is 'open'. IF (PF&#x2248;0) and ((Vrms/Irms)&#x3c;T), THEN the circuit status is 'short'. PF is the power factor. T is a threshold value.

A tissue removal system for extracting a tissue specimen from a patient is disclosed. The system has a retrieval bag, a first electrode, and a return electrode. The retrieval bag has a flexible container with an opening. The first electrode is coupled to an interior of the flexible container, and has a conductive wire with an exposure area, a first load-bearing area, a coating having a first active electrode surface area, and an impedance that is greater than an impedance of the conductive wire. The first active electrode surface area is less than the exposure area. The coating is configured to degrade during application of electrosurgical power and wherein the degradation expands the first active electrode surface area during the application of the electrosurgical power.

A cable stand-off for use with an electrosurgical system includes an accordion body portion having a plurality of panels, and a plurality of hinges. Each panel has at least one hole formed therethrough. The holes of the plurality of panels are axially aligned with one another. The plurality of hinges couples adjacent panels to one another. In one embodiment, the hinges couple adjacent panels in a tip-to-tail fashion. The accordion body portion may be made of a flexible material. Each panels may further include at least one slot extending from a hole to an edge of the panel.
