Abstract

Devices and methods are used to modify a metabolic pathway of a digestive system by creating a pathway within the intestinal tract through an anastomosis between a proximal location within the intestinal tract and a distal location within the intestinal tract. In some examples, the small intestine has a first initial length and the created pathway defines a second length of the intestinal tract that is approximately ten to seventy percent of the first initial length of the small intestine.

Abstract

A filter connection for a smoke evacuation device includes a filter canister assembly and a socket. The filter canister assembly has a cross-sectional shape with only one line of symmetry that corresponds to a cross-sectional shape of the socket so that the filter canister can only be inserted into the socket in one orientation. One or more key notches on the filter canister may also ensure that the filter is properly installed. A seal creates an airtight boundary between the filter canister and a recess of the socket so that a sealed path in communication with the smoke evacuation device is established before the filter canister is fully inserted into the socket. An electronic connection is made between the filter canister and the socket after the airtight boundary is created.

Abstract

Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.

Abstract

A radio frequency (RF) current sensor for remotely activating a smoke evacuation device in an electrosurgical system includes a sensor body with a cable interfacing sidewall and a retaining member. The cable interfacing sidewall and the retaining member define a retention pocket for receiving a cable communicating RF current. The RF current sensor additionally includes a sensor element for detecting RF current in the cable and a sensor cable in electrical communication with the sensor element. The RF current sensor can operate in at least two modes, depending on whether the cable communicates RF current to a monopolar or bipolar electrosurgical instrument, but regardless of the operation mode, the sensor cable can communicate an activation signal and a current signal derived from the detected RF current to the smoke evacuation device, which activates or adjusts the period of time and/or the smoke evacuation flow rate of a vacuum source.

Abstract

A switch comprising an interior cavity and a switching element movably disposed within the interior cavity to define a first position and a second position, the second position being different from the first position. A biasing element imparts a biasing force to the switching element to place the switching element in either the first or the second position until an external force imparted to the switching element exceeds the biasing force, thereby causing the switching element to move to the other one of the first or the second position. A biasing force-adjusting element is cooperatively engaged with the biasing element, wherein a magnitude of the biasing force is adjustable using the biasing force-adjusting element. An electrically-conductive contact, coupled to the switching element, defines a first switching state when the switching element is in the first position and a second switching state when the switching element is in the second position.

Abstract

Devices and methods are used to modify a metabolic pathway of a digestive system by creating a pathway within the intestinal tract through an anastomosis between a proximal location within the intestinal tract and a distal location within the intestinal tract. In some examples, the small intestine has a first initial length and the created pathway defines a second length of the intestinal tract that is approximately ten to seventy percent of the first initial length of the small intestine.

Abstract

A surgical instrument includes an end effector, an actuator coupled to the end effector and actuating it, a handle coupled to the end effector and having an electric motor disposed therein actuating the actuator when supplied with power, and a post-termination braking circuit including a power supply switch at the handle. The switch has a break-before-make configuration, a power-supplying state in which power is supplied to the motor, and a power-removed state in which power is not supplied to the motor. The braking circuit short-circuits power to the motor when the switch is in the power-removed state. A method for post-termination braking of the motor utilizes the permanent magnetic field to counteract inertia-induced over-stroke of the motor, drive train, and/or actuation assembly after powered operation by short-circuiting the still-spinning motor to create an electrically generated magnetic field in opposition to the permanent magnetic field upon ceasing supply of power.
