The present application provides a ligation release device, comprising: a handle (1), an operating component (2), a suction component (3), a release component (4) and an illumination component (5), wherein the illumination component (5) is arranged in the handle (1) and comprises a light source (51), a wire (52) and a control switch (53), and the control switch (53) is connected to the light source (51) by means of the wire (52). In practical applications, the light source (51) can be turned on by operating the control switch (53), thereby illuminating a ligation area at the distal end of the handle (1), eliminating shadow influence and facilitating the implementation of ligation operation. The ligation release device can improve the ease and accuracy of surgical operation without an external auxiliary apparatus.

A tongue maneuvering apparatus has a body, a first attachment site, and a second attachment site. The body includes a bulb, a tongue receiving portion, a tongue aperture, and a slot. The body may be a thin, pliable plastic, such as silicone, so as to create proper suction with the tongue when inserted into the tongue receiving portion. A healthcare provider is able to extend and manipulate a patient's tongue so as to clearly view the mouth and throat without activating the gag reflex and maintaining control of the tongue by the provider.

The present specification is directed towards catheter devices having expandable and collapsible lumens. Air or fluid is pumped into the catheter wall to cause it to expand. Alternatively, wires are embedded within the wall and a direction of flow of electrical current through the wires is modulated to enable the catheter device to be in the collapsed or expanded state. For example, a first wire is embedded within the wall and is helically wound along a length of the catheter device. A second wire is provided that can be removably positioned within the lumen. The direction of flow of electric current through the first and second wires is modulated to enable the catheter device to be in the collapsed or expanded state.

An insertable device is designed to control uterine hemorrhaging after birth by facilitating contractile movement of the uterus. An insertable device comprises a tube having a connecting portion and a suction portion and a seal positioned along the length of the connecting portion proximal to the suction portion. Upon insertion of the suction portion and seal into the uterus, the seal abuts a vaginal canal and forms a seal between a vaginal opening and the uterus. The suction portion comprises a first loop having an opening that is oriented away from an interior wall of the uterus when inserted into the uterus. The connecting portion of the tube couples to a pump that when actuated generates a negative pressure within the uterus, resulting in a uniform mechanical stimulus to the uterine wall in order to facilitate tamponade and contractile movement of the tissue.

Disclosed herein is a tissue engaging surgical tool that is configured to selectively hold or grasp a portion of tissue with a suction cup or flexible end portion. The device is configured to increase or decrease pressure between the flexible end portion and tissue that the end portion is held against, thereby creating a releasable suction or vacuum force.

In various embodiments, a layer of material can comprise a body, a proximal end portion, and a distal end portion. The proximal end portion can be releasably secured to a staple cartridge of a surgical end effector, and the distal end portion can be releasably secured to an anvil of the surgical end effector. The layer of material can comprise a tissue thickness compensator.

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.

In some embodiments, a vitrectomy probe may include an inner cutting tube reciprocating in an outer tube. The outer tube includes a side port and the inner tube includes a distal cutting port, and, in some embodiments, an additional side port. In some embodiments, the inner tube may also include a flat upper edge that cuts across the outer tube side port. In some embodiments, a diaphragm drives the inner tube and may have an open-stroke side with a lower hardness material than a closed-stroke side. In some embodiments, an aspiration tube coupled to the vitrectomy probe may include a first aspiration tubing and a second aspiration tubing with a lower hardness than the first aspiration tubing. In some embodiments, the vitrectomy probe may be coupled to pneumatic tubing that is stepped or tapered.

A method for closure of the left atrial appendage (LAA), including: placing an LAA reshaper in contact with an LAA wall or near the LAA wall; invaginating at least a portion of the LAA into the left atrium (LA); reshaping by the LAA reshaper the LAA during the invagination; fastening the invaginated at least a portion of said LAA; and retracting the LAA reshaper from the LAA

A staple cartridge comprising a tissue thickness compensator is disclosed. The tissue thickness compensator comprises an external layer and tubular elements. The tubular elements are interconnected and positioned within the external layer. The tubular elements comprise apertures defined therein and the tubular elements are configured to collapse as pressure is applied to the tissue thickness compensator by tissue during the firing motion. The apertures enable fluids from the tissue to permeate the tissue thickness compensator.
