An endoscopic forceps is provided and includes a housing having a shaft. An end effector assembly operatively connects to a distal end of the shaft and has a pair of first and second jaw members. One of the first and second jaw members is movable relative to the other jaw member from an open position, to a clamping position. One of the first and second jaw members includes one or more cam slots defined therein and configured to receive a cam member that upon movement thereof rotates the movable jaw member from the open position to the clamping position. A resilient member is operably coupled to the jaw member that includes the one or more cam slots. The resilient member is configured to provide a camming force to the cam slot and to bias the first and second jaw members in the clamping position.

Devices and methods for monitoring the temperature of tissue at various locations in a treatment volume during fluid enhanced ablation therapy are provided. In one embodiment, an ablation device is provided having an elongate body, at least one ablation element, and at least one temperature sensor. The elongate body includes a proximal and distal end, an inner lumen, and at least one outlet port to allow fluid to be delivered to tissue surrounding the elongate body. The at least one ablation element is configured to heat tissue surrounding the at least one ablation element. The at least one temperature sensor can be positioned a distance away from the at least one ablation element and can be effective to output a measured temperature of tissue spaced a distance apart from the at least one ablation element such that the measured temperature indicates whether tissue is being heating to a therapeutic level.

A forceps instrument comprises, for the support of at least one pivotally supported branch, a bearing insert which is inserted into a base in order to support at least one pivotable branch. The bearing insert may be inserted transversely with respect to the pivot axis into a corresponding compartment of the base and fixed there in the compartment, due to detent action. The bearing insert comprises two bearing elements, including cylindrical journals, which are arranged on bearing parts of the bearing insert, without being in contact with each other, the bearing parts having the form of plates, that are oriented parallel to each other. The two journals come into engagement with corresponding openings of the branch, in which case the distance remaining between the end sides of the journals can be used for the arrangement of miscellaneous elements, including a cutting knife.

A medical device, including: a cooling system; a heating system; and an applicator including a cold base operationally coupled to the cooling system and a heating element operationally coupled to the heating system, and an applicator head collocated with the cold base and the heating element and adapted for applying a combination of heat and cold to a target area such as target tissue.

A treatment tool includes a first grasper and a second grasper. The first grasper includes a treatment portion that includes a treatment surface and an opposing surface, and a holder portion that is mounted on the opposing surface. The holder portion is formed of an elastically deformable material, and includes a first region having a first contact surface, a second region having a second contact surface, and a connection region that is arranged between the first contact surface and the second contact surface and that includes a concave portion. The holder portion is mounted on the opposing surface in an elastically deformed state such that the first contact surface and the second contact surface are in contact with the opposing surface and such that a depth of the concave portion is smaller than a depth of the concave portion is a non-elastically deformed state.

An endoscopic instrument containing a retractable tool at its end that is articulated by engaging an actuator that moves pull wires to angularly move the tip of the instrument along a plane for conducting a procedure at a target site. The tool of instrument is linearly move from an extension position to a retracted position by another actuator. The instrument provide rotational control of the tool and instrument tip portion with a rotational actuator for rotating housings that carry both pull wires and a conducting wire connected to the tool.

Transducer-based systems and methods may be configured to display a graphical representation of a transducer-based device, the graphical representation including graphical elements corresponding to transducers of the transducer-based device, and also including between graphical elements respectively associated with a set of the transducers and respectively associated with a region of space between the transducers of the transducer-based device. Selection of graphical elements and/or between graphical elements can cause activation of the set of transducers associated with the selected elements. Transducer activation characteristics, such as initiation time, activation duration, activation sequence, and energy delivery characteristics, can vary based on numerous factors. Visual characteristics of graphical elements and between graphical elements can change based on an activation-status of the corresponding transducers. Activation requests for a set of transducers can be denied if it is determined that a transducer in the set of transducers is unacceptable for activation.

The present disclosure relates generally to the field of medical devices and establishing fluid communication between body lumens. In particular, the present disclosure relates to devices and methods for placing the muscularis layers of first and second body lumens in contact to establish a long term or permanent open flow or access passage therebetween.

The disclosed technology is directed to a treatment tool having a blade. The blade includes a treatment surface configured to engage with a treatment target. A heater is configured to be coupled to the blade. The heater includes respective first and second heat generating surfaces each of which extending in a direction transverse to the treatment surface. Respective first and second thermally conductive members each of which is interposed between the respective first and second heat generating surfaces and the blade so as to thermally engage the respective first and second heat generating surfaces and the blade to one another. The respective first and second thermally conductive members includes respective first and second thermal conductivity anisotropies each of which being higher in longitudinal directions of the blade and each of which being lower in widthwise directions of the blade that are transverse to the longitudinal directions.
