Abstract: A medical device, a clip unit, and a method for indwelling a clip unit. The medical device includes a treatment portion, an operation wire that can operate the treatment portion, and a link that can releasably connect the treatment portion and the operation wire. The link includes a hook that includes first and second deformation portions, and a base that can be releasably coupled to the hook. The first deformation portion is capable of being deformed by movement of the operation wire, and the second deformation portion is capable of being deformed by further movement of the operation portion after the first deformation portion is deformed.

Abstract: A clip-cartridge assembly and a clip applicator are provided. The clip-cartridge assembly includes a clip-cartridge, a clip delivery device, and a clip jaw provided on a side of the clip-cartridge. The clip-cartridge includes an accommodation cavity for placing a ligation clip and the clip delivery device; the clip delivery device includes an elastic member and a clip pushing block for pushing the ligation clip within the accommodation cavity to move; and if the clip jaw is closed, the elastic member, by an elastic force of the elastic member, drives the clip pushing block to move in a movement direction toward the clip jaw.

Abstract: A stent delivery system includes a core member and an expandable member coupled to the core member distal segment. A stent extends along the core member distal segment such that an inner surface of the stent is positioned over the expandable member. The stent has a primary heat-set configuration where the stent is radially expanded, and a secondary heat-set configuration where the stent is radially compressed. The expandable member is adapted to radially expand at least a portion of the stent from a radially compressed configuration toward a radially expanded configuration.

Abstract: A surgical grasper includes an articulation assembly configured to enable a tool assembly to pivot in a first plane and articulate in a second plane orthogonal to the first plane. The surgical grasper eliminates the center line pivot joint used in conventional articulation mechanism, which, in turn, enables use of thicker cable that provides greater clamping force of first and second jaws of the tool assembly.

Abstract: A closure device includes a first ring structure having a first distal portion and a first medial portion and a second ring structure having a second distal portion and a second medial portion. The first and second distal portions are movable between an open position, where the first and second distal portions form an angle relative to one another for receiving target tissue therebetween, and a closed position, where the first and second distal portions are drawn toward one another for gripping the target tissue. The device also includes an anvil about which the first and second medial portions are formed. Either one of proximal motion of the anvil relative to the first and second rings or proximal motion of the medial portions relative to the anvil causes the first and second distal portions to move into either one of the open position or the closed position.

Abstract: A surgical system includes a skull attachment device that includes a support base configured to seat against a skull of a patient and one or more pins extending from a bottom surface of the support base and configured to pierce the scalp to seat the skull attachment device against the skull. The surgical system also includes an interface disposed along a top surface of the support base and having a shape that compliments a profile of a mating feature of a stereotactic device for defining a position and an orientation of the stereotactic device with respect to the support base while the interface is engaged with the mating feature.

Abstract: A surgical robot includes a surgical tool including a bendable joint portion, and a bending tendon connected to the joint portion and configured to bend the joint portion, a tube connected to the surgical tool and configured to accommodate the bending tendon therein, a base housing configured to rotatably support the tube and accommodate the bending tendon that passes through the tube, a bending driver configured to grasp the bending tendon, and translate in a longitudinal direction parallel to a rotation axis of the tube with respect to the base housing, and a rotation driver configured to rotatably support the tube with respect to the base housing, wherein when the tube rotates, the rotation driver is connected to one portion of the bending driver that grasps the bending tendon, and rotates the tube and the bending tendon together.

Abstract: A stent delivery device for delivering a self-expanding stent comprises an inner sheath including a proximal end portion and a distal end portion, a stent stopper including a stopper main body that is circumferentially disposed over at least a portion of the inner sheath at the proximal end portion, and at least one projection extending radially outward from the stopper main body for releasably engaging a portion of the self-expanding stent, and an outer sheath slidably disposed over the inner sheath and the stent stopper. The at least one projection includes a distal end surface and a proximal end surface, and the proximal end surface includes a recess extending into a body of the projection toward the distal end surface.

Abstract: A medical device for cutting substances inside a body lumen includes a flexible and elongated drive shaft including a distal portion and a proximal portion, a cutting member connected to the distal portion of the drive shaft to be rotatable with the drive shaft, and a hub located at the proximal portion and supporting the drive shaft, the hub including a first bearing mounted on the drive shaft and an elastic ring that is made of an elastic material on an outer periphery of the first bearing.

Abstract: A handheld body cavity access device includes a handle having a distal end, a proximal end, a longitudinal axis, and a cavity. A dilator assembly has a proximal end coupled to the handle and a distal end. A blade assembly is at least partially disposed within the dilator assembly and has a proximal end, a distal end, and a blade hub coupled to the proximal end and disposed in the cavity of the handle. The dilator assembly is movable axially between a retracted position, in which a distal end of the blade assembly extends from the distal end of the dilator assembly, and an extended position, in which the distal end of the blade assembly is covered by the distal end of the dilator assembly. The blade hub includes a body defining a bore aligned with the longitudinal axis and a tab extending away from the longitudinal axis.

Abstract: A surgical stitching device is configured for single hand operation that enables passage of a suture needle through tissue with minimal operational requirement. The surgical needle is selectively securable to a tool assembly of the surgical stitching device. The tool assembly includes a jaw configured to securely support various surgical needles in various orientations.

Abstract: A closure device includes a first ring structure having a first distal portion and a first medial portion and a second ring structure having a second distal portion and a second medial portion. The first and second distal portions are movable between an open position, where the first and second distal portions form an angle relative to one another for receiving target tissue therebetween, and a closed position, where the first and second distal portions are drawn toward one another for gripping the target tissue.
