A surgical clip may be configured to ligate tissue. The surgical clip may include first and second leg members. The first leg member may have a proximal portion, a distal portion, a convex first inner surface, and a convex first outer surface. The first leg member may also include an inner portion at least partially defining the first inner surface and an outer portion at least partially defining the first outer surface. The inner and outer portions may be joined at first and second portions of the first leg member and separated by a channel. The second leg member may include a proximal portion, a distal portion, a second inner surface, and a second outer surface. The first and second leg members may be movable relative to each other between open and closed configurations, and the first and second inner surfaces may be configured to ligate the tissue when in the closed configuration.

Provided are a bending structure and a flexible tube for a medical manipulator, which comprise a main body that is composed of the wave washers stacked in an axial direction and kept a stacked state, the main body being bendable according to the expansion and contraction in the axial direction. Accordingly, linearity of load characteristics based on load and a bending angle is made high to make it possible to obtain the flexible tube having superior load bearing and bendability while conducting size reduction.

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

An apparatus for insertion into a body through a working channel of an endoscope includes a catheter including a dilator, a guide tube disposed in a lumen of the catheter, and a handle including a puncturing actuator operatively coupled to the proximal end of the guide tube. The dilator may be a cautery device and/or a balloon. The apparatus may also include a stylet needle that includes a cutting distal end for puncturing tissue and extends through a lumen in the guide tube. The handle may further include a stopper detachably coupled to the puncturing actuator to fix a position of the puncturing actuator on the handle, and moveable on the handle independently of the puncturing actuator when detached from the puncturing actuator. The disclosed embodiments also include a method for forming a passageway in a wall of a hollow body organ using the apparatus.

A device for treating a tissue opening includes a proximal portion including an elongated flexible member, a capsule releasably coupled to a distal end of the flexible member and including a lumen extending therethrough and a clip including a pair of arms movably housed within the capsule. A suture extending along a first one of the pair of arms and including a loop at a distal end thereof extending across an opening extending through the first one of the pair of arms. A suture grabbing element extending laterally from a second one of the pair of arms and including a hook so that, when the pair of arms are moved toward a closed configuration, the hook extends through the opening to grab the loop and draw the distal end of the suture from the first one of the pair of arms toward the second one of the pair of arms.

Degree of occlusion is monitored for an occlusive device configured to occlude passage of fluid between two compartments in a lumenal space of a body of a patient. In some embodiments, changes in an electrical signal measured from the body of the patient are induced by perturbing the fluid; for example, by “tagging” a portion of fluid with a perturbation of temperature and/or composition. The degree of occlusion is estimated based on the measured changes. The electrical signal changes may be indicative of fluid movements redistributing the perturbed fluid among the two compartments; for example, by diffusion, mixing, and/or jetting of fluid.

A torque balancing device, a self-balancing joint and a surgical robot are provided. The torque balancing device includes a first body, a second body, an elastic part and a transmission part, the first body includes a first connection end and a first opposite end opposite to the first connection end, the second body includes a second connection end and a second opposite end opposite to the second connection end, the second connection end of the second body is rotatably connected to the first connection end of the first body, the elastic part is provided in the first body, and the transmission part is connected to the second body and the elastic part.

A surgical guide includes a body including a beveled distal surface configured to being placed against a side of a foot and a proximal surface. The body includes at least one channel that extends between the beveled distal surface and the proximal surface of the body. At least one K-wire is receivable in the at least one channel and is configured to being received in a metatarsal and a capital fragment of the foot. The guide includes a handle, and a preset angle is defined between a longitudinal axis of the body and the beveled distal surface of the body. The preset angle is between approximately 25° and approximately 30°.

A staple cartridge assembly for use with a surgical stapling instrument includes a staple cartridge including a plurality of staples and a cartridge deck. The staple cartridge assembly also includes a compressible adjunct positionable against the cartridge deck, wherein the staples are deployable into tissue captured against the compressible adjunct, and wherein the compressible adjunct comprises a first biocompatible layer comprising a first portion, a second biocompatible layer comprising a second portion, and crossed spacer fibers extending between the first portion and the second portion.
