An exemplary surgical device includes a shaft with a lumen defined therethrough and an element movable from a stored position to a deployed position in which a larger portion of the element extends out of the distal end of the lumen; wherein motion from the stored position to the deployed position causes a first leg of the element to advance distally relative to the distal end of the shaft, and causes a second leg of the element to move proximally relative to the distal end of the shaft.

A tissue specimen removal device comprises a specimen bag; a flexible ring, the flexible ring configured to form a top opening of the specimen bag; a cannula assembly comprising: an inner tube portion and an outer tube portion. The device may further comprise a connector carrier, the connector carrier configured to retain at least one connector housing, the at least one connector housing comprising one or more connector portions and reside within an interior of the connector carrier, and wherein the connector carrier can be moved from a position within the cannula assembly to outside the cannula assembly.

Described here are devices, systems, and methods for closing the left atrial appendage. The methods described here utilize a closure device for closing the left atrial appendage and guides or expandable elements with ablation or abrading elements to ablate or abrade the left atrial appendage. In general, these methods include positioning a balloon at least partially within the atrial appendage, positioning a closure assembly of a closure device around an exterior of the atrial appendage, inflating the balloon, partially closing the closure assembly, ablating the interior tissue of the atrial appendage with the inflated balloon, removing the balloon from the atrial appendage, and closing the atrial appendage with the closure assembly.

A surgical instrument includes an end effector and a housing mechanically coupled to the end effector. The end effector includes a first actuating device configured to perform a first surgical procedure and a second actuating device integrally associated with the first actuating device and configured to perform a second surgical procedure, the second surgical procedure being independently operable and different than the first surgical procedure. An outer portion of the first actuating device and an outer portion of the second actuating device form a portion of an outer housing of the end effector. The housing includes a first actuator, mechanically coupled to the first actuating device and configured to impart movement to the first actuating device and a second actuator, mechanically coupled to the second actuating device and configured to impart movement to the second actuating device.

An elongated medical sheath is configured to be movable and positionable proximate to a biological feature of a patient. An expandable-and-collapsible support structure is configured to be selectively movable, at least in part, between an interior of the elongated medical sheath and an exterior of the elongated medical sheath. An energy-emitting assembly is supported by the expandable-and-collapsible support structure.

A medical support device includes a processor used for an endoscope apparatus including an endoscope that images a luminal organ and a treatment tool that is energized in a state of being in contact with a treatment target part included in the luminal organ to cut the treatment target part. The processor is configured to output permission and non-permission information indicating whether or not the energization is permitted. Whether or not the energization is permitted is determined on the basis of a captured image that has been obtained by imaging the luminal organ with the endoscope and that includes the treatment tool.

An ophthalmic surgical device in accordance with various embodiments of the present disclosure comprises an elongate element and a filament. The device may further comprise one or more of a shaft, an actuator, an actuator handle, a shaft handle, a vent, and a filament stop. The device may be used to mechanically push objects, as in retinal detachment repair, grasp objects, as in the removal of a dislocated intraocular lens or an intraocular foreign body, aspirate fluid, and cut materials, such as intraocular fragments.

An apparatus to treat a patient, the apparatus comprises a carrier having a proximal end and a distal end, an optical fiber to couple to a light source, a fluid delivery element comprising a nozzle having an orifice on the distal end, and an alignment structure to align the optical fiber with the orifice. A distance extends between the alignment structure and the orifice, such that the light beam emitted from the optical fiber diverges so as to allow energy transmission and fluid flow through the orifice. In some embodiments, the apparatus to ablate tissue comprises a source of pressurized fluid, and the nozzle is coupled to the source of pressurized fluid to release a fluid stream.

A conductive adhesion preventing film for medical use, includes: a nonconductive base material; and a linear conductor having a length of 10 m or more and a diameter of more than 50 nm and contained in the conductive adhesion preventing film by an amount of 5% by mass or more and 40% by mass or less, wherein the conductive adhesion preventing film is formed on an electrode surface of a medical device performing at least one of incision, resection, coagulation, and ablation on living tissue by applying a high frequency voltage.
