摘要:
Rotational couplers for use with surgical devices that are actuated by semi-flexible actuators such as wires and the like. The couplers enable the actuators to apply various actuation motions to actuation features on the surgical device as well as other actuators to apply axial and rotational motions to the surgical device to manipulate the device into various orientations relative to an elongate shaft to which the device is movably attached.

A method of repositioning an injection port comprises positioning the injection port at a first location in a patient's body and extending fasteners of the injection port to substantially secure the injection port at the first location. The fasteners are then retracted to substantially unsecure the injection port from the first location in the patient's body. The injection port is then moved to a second location in the patient's body. The fasteners are then re-extended to substantially secure the injection port at the second location in the patient's body. The injection port includes a port body. The fasteners are integral with the port body. The fasteners may be selectively extended and retracted relative to the port body. For instance, the fasteners may be pivoted relative to the port body to transition between extended and retracted positions. The extension and retraction of fasteners may be provided through a port applier.

An injection port applier is configured to engage an injection port that has integral fasteners that are movable from a non-deployed position to a deployed position. The applier comprises a shaft, a port engagement portion, and a handle. The port engagement portion is includes a fastener deployment member that is operable to move the fasteners to the deployed position. The handle comprises a first handle portion and a second handle portion. The second handle portion is movable distally relative to the first handle portion in order to actuate the fastener deployment member, to thereby move the fasteners to the deployed position. An elongate actuating member couples the second handle portion with the fastener deployment member. One part of the elongate actuating member translates longitudinally in response to the second handle being moved distally; while another part of the elongate actuating member rotates in response to the first portion translating.

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that has an ultrasonic blade that protrudes from an ultrasonic transducer assembly. In some embodiments, the ultrasonic blade coaxially extends through a rotatable tissue cutting blade that is rotatably supported by a housing that supports the ultrasonic transducer assembly. In other embodiments, the ultrasonic blade and the tissue cutting blade are both selectively rotatable relative to the housing. In yet other embodiments, the tissue cutting blade and the ultrasonic blade are supported relative to each other in separate sheaths attached to the housing.

In one general aspect, various embodiments are directed to methods for treating tissue within an aqueous environment. Various methods may include introducing a cutting implement of a surgical instrument into the aqueous environment. The cutting implement may have at least one cutting surface thereon and at least one ultrasonic portion thereon and be selectively rotatable within a hollow sheath. The methods may include rotating or rotatably oscillating the cutting implement within the hollow sheath for tissue cutting purposes. The cutting implement may also be retained in a position wherein the ultrasonic portion of the cutting implement may be applied to tissue and then have ultrasonic motion applied thereto.

A tissue thickness compensator can comprise a plurality of layers. Various embodiments are disclosed herein for manufacturing a tissue thickness compensator. In certain embodiments, a tissue thickness compensator can comprise at least one medicament tube, capsule, and/or packet contained therein
摘要:
Various powering devices are provided for transferring and/or generating energy from numerous sources to a communicating member implanted in a patient. The energy transferred to or generated by the communicating member can be used to provide power to an implantable restriction system configured to form a restriction in a pathway.

An electrosurgical device comprises a body, an end effector, a cutting member, and a shaft extending between the body and the end effector. The end effector includes a pair of jaws and at least one electrode operable to deliver RF energy to tissue clamped between the jaws. The cutting member is operable to cut tissue clamped between the jaws. The shaft includes an articulation section that is operable to selectively position the end effector at non-parallel positions relative to the longitudinal axis of the shaft. The articulation section may include beads, segments, asymmetric features, preformedly bent features, an integral hinge, a helical cutout or spring, clevis features, an angled joint, a beaded actuation linkage, and/or an offset pivot, among other things. The device may also include a crimped cutting member, a retroacting cutting member, dual pivoting jaws, and/or a wire tensioning assembly.
摘要:
A surgical device comprises an ex vivo magnet and an in vivo sled magnetically attracted to the ex vivo magnet. The sled can be positioned and anchored within a patient by moving the ex vivo magnet. The sled defines a longitudinal axis. An arm extends from the sled. The arm is moveable relative the sled between a retracted position and an extended position. The arm comprises an end effector. A locking mechanism operatively connected to the arm to lock the arm in the retracted and extended positions. The mechanism may include a rack that both rotates about a pinion and translates tangentially about the pinion.
摘要:
Methods and devices are provided for controlling movement of a working end of a surgical device, and in particular for performing various surgical procedures using an instrument having an end effector that can be articulated relative to an elongate shaft of the device. In certain embodiments, the end effector can also optionally rotate relative to the elongate shaft of the device, and/or the shaft can rotate relative to a handle of the device.
