The present teachings provide for a device with a membrane and an underlying switch, an underlying switch actuator, or both that has a unique tactile pattern that is felt through the membrane when the membrane is aligned with the switch, switch actuator, or both, corresponding to the electrical state of the device. The membrane, the switch, the switch actuator or a combination thereof can be repositioned from a first position to a second position so that a different tactile feel is present through the membrane corresponding to a second electrical state.

Described herein are various method of using a direct drive system to perform procedures at a distance. One exemplary method include tying a knot or suturing at a distance with a first and second end effector. The direct drive system can enable sufficient end effector dexterity, including the ability to control various degrees of freedom of end effector movement, and allow a user to perform complicated task at a distance. In one aspect the direct drive system includes flexible tools that permit access to surgical site via a natural orifice.

Surgical instruments and/or fastener apparatuses comprising an end effector with a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. At least one of the jaws may comprise a channel for receiving a cartridge containing a plurality of surgical fasteners. Also, an electrically powered actuator may be for deploying the surgical fasteners and may comprise a power source and a motor. An activation mechanism may be attached to the handle to move the pair of jaws from the open to the closed position and to activate the actuator. A lockout mechanism may be configured to permit current to flow from the power source to the motor when the pair of jaws is in the closed position and to prevent current from flowing to the power source to the motor when the pair of jaws is in the open position.

A surgical tool for piercing tissue of a body comprises a hollow external component (1) having a peripheral wall (11), an internal component (2) movable disposed inside the external component (1) and having a piercing head (21); when the piercing head (21) and the internal component (2) retract relative to the external component (1), the movable component (3) deforms partially, expands outwardly in a radial direction, and fills the bladder (6). The movable component can be deformed to expand outward in the radial direction, so as to make the bladder to expand, so that the surgical tool can be positioned on the body of the patient.

A tissue displacing and fastening device is provided for manipulating and fastening tissue together. The device includes a tissue displacing elements, which displaces tissue. A fold is formed from the displaced tissue and the tissue is fastened together to secure the fold.

Devices, systems and methods for passing a suture. In general, described herein are suturing devices, such as suture passers, as well as methods of suturing tissue. These suture passing devices may include dual deployment suture passers in which a first distal jaw member is moveable at an angle with respect to the longitudinal axis of the elongate body of the device and the second distal jaw member is retractable proximally to the distal end region of the elongate body and/or the first jaw member.

Surgical instruments and/or fastener apparatuses comprising an end effector with a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. At least one of the jaws may comprise a channel for receiving a cartridge containing a plurality of surgical fasteners. Also, an electrically powered actuator may be for deploying the surgical fasteners and may comprise a power source and a motor. An activation mechanism may be attached to the handle to move the pair of jaws from the open to the closed position and to activate the actuator. A lockout mechanism may be configured to permit current to flow from the power source to the motor when the pair of jaws is in the closed position and to prevent current from flowing to the power source to the motor when the pair of jaws is in the open position.

A tissue recruiting device for treating and closing a defect and methods of using the same. The grasping device includes a grasping portion and a coupling portion. The grasping portion includes a plurality of helical coils. The coupling portion is operably coupled with an actuation element. An actuation assembly is operable to translate and rotate the actuation element such that the grasping device pierces into and grasps target tissue.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An application instrument for an exclusion device may include an end effector including a head configured to be disposed distally on a shaft, a stationary jaw fixedly disposed on the head and configured to releasably couple to a first clamping portion of an exclusion device, the exclusion device being biased in a closing direction, and a movable jaw movably disposed on the head and configured to releasably couple to a second clamping portion of the exclusion device. The movable jaw may be movable relative to the stationary jaw to reconfigure the exclusion device from a closed configuration to an open configuration. The movable jaw may be oriented generally parallel to the stationary jaw when the exclusion device is in the open configuration and the closed configuration.

Exclusion devices for anatomical structures, and related instruments and related methods, are disclosed. An exclusion device may include a first clamping portion, a second clamping portion opposing the first clamping portion, and/or a biocompatible fabric cover at least partially sheathing the first clamping portion and/or the second clamping portion. The cover may be generally tubular and/or may define a relaxed circumference when the first clamping portion and the second clamping portion are in a closed configuration. At least a portion of the cover may be configured to stretch to a stretched circumference of about 2× to about 3× the relaxed circumference when the first clamping portion and the second clamping portion are reconfigured from the closed configuration to an open configuration.
