In general, the methods and devices allow a surgeon to remotely and selectively attach various interchangeable surgical end effectors to a shaft located within a patient's body, thus allowing the surgeon to perform various procedures without the need to remove the shaft from the patient's body. In an exemplary embodiment, multiple end effectors can be introduced into a body cavity. The end effectors can be disassociated or separate from one another such that they float within the body cavity. A distal end of a shaft can be positioned within the body cavity and it can be used to selectively engage one of the end effectors. In particular, the device can be configured to allow each end effector to be remotely attached and detached from the distal end of the shaft.
Methods and devices are provided for activating brown adipose tissue (BAT). Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss. In one embodiment, a medical device is provided that activates BAT by electrically stimulating nerves that activate the BAT and/or electrically stimulating brown adipocytes directly, thereby increasing thermogenesis in the BAT and inducing weight loss through energy expenditure.

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.
Methods and devices are provided for activating brown adipose tissue with targeted substance delivery. Generally, the methods and devices can activate BAT to increase thermogenesis, e.g., increase heat production in the patient, which over time can lead to weight loss and/or improved metabolic function. In one embodiment, a chemical configured to stimulate nerves that activate the BAT and/or to stimulate brown adipocytes directly can be delivered to a patient, thereby increasing thermogenesis in the BAT and inducing weight loss and/or improved metabolic function through energy expenditure.

Electrosurgical instruments and associated methods are disclosed herein. Embodiments of the electrosurgical instruments can include an elongate shaft (30) that can articulate an end effector (40) relative to the elongate shaft, with the end effector including opposed jaws (42, 44) and positioned at a distal end of the elongate shaft. In addition, electrosurgical instruments are provided that include a cutting feature or knife that is coupled to the end effector and can axially translate relative to the elongate shaft. Furthermore, the knife can be rotated relative to the elongate shaft, which can cause simultaneous rotation of the end effector. Electrosurgical instruments are also provided that include an end effector including opposed jaws that are configured to rotate relative to the elongate shaft and grasp objects (i.e., via opening and closing the opposed jaws). Electrical energy can also be passed through the electrosurgical instrument for performing electrosurgical procedures.

In one embodiment a surgical device, includes a handle and an elongate shaft extending distally therefrom with opposed jaws coupled to a distal end thereof. The surgical device can include a trigger pivotally movable about a first pivot axis during a first range of motion from an open position toward a closed position, to cause the opposed jaws of the end effector to move from an open position to a partially closed position. The trigger can further be pivotally movable about a second pivot axis during a second range of motion from the partially closed position to the fully closed position, without causing corresponding movement of the opposed jaws from the open position to the closed position.
Surgical devices are provided having power-assisted or fully powered jaw closure. The devices herein generally include a handle portion, an elongate shaft, and an effector having first and second jaws configured to engage tissue. A motor and one or more compression springs can be operatively coupled, and activation of the motor can compress the spring(s) to reduce the amount of user supplied force to compress tissue between the jaws. In some embodiments, the devices can be configured to regulate an amount of compression applied by the jaws prior to, during, and/or after cutting of the tissue to promote hemostasis. For example, the devices can include sensors, processors, and/or other components that analyze data indicative of tissue type and tissue load. Based on this feedback, the device can automatically adjust the amount of compression or energy applied to the tissue to seal the tissue.
