A method is disclosed for providing a continuous compression fixation device for coupling a first bony structure to a second bony structure. The method can include providing a body structure and providing a plurality of arm structures coupled to and extending from the body structure. The method can include deflecting the tips of the at least one of the plurality of arm structures and the at least one opposed one of the plurality of arm structures away; coupling the at least one of the plurality of arm structures to the first bony structure and the at least one opposed one of the plurality of arm structures to the second bony structure; and releasing the tips of the at least one of the plurality of arm structures and the at least one opposed one of the plurality of arm structures to provide the compressive force.

Apparatus and methods are provided for closing a tubular structure within a patient's body. The apparatus includes a needle including a proximal end including a hub, a distal end including a sharpened distal tip, a lumen having an oblong cross-section extending proximally from the distal end, and defining a longitudinal axis between the proximal and distal ends, and a clip deliverable from the lumen. The clip is compressible between a relaxed state in which a plurality of tines of the clip are shaped to engage and close a tubular structure within a patient's body, and a stressed state in which the tines are compressed to allow the clip to be loaded into the. The apparatus may also include a pusher member for deploying the clip from the distal tip of the needle such that the tines engage and close a tubular structure through which the tubular member is directed.

A circular stapler apparatus for stapling tissue includes a staple and pledget assembly and a circular staple head operable to drive staples toward an anvil. A staple of the staple and pledget assembly has a pair of legs disposed substantially perpendicular to a crown of the staple in a first position. The pair of legs is operable to advance against a pocket in the anvil to form a staple with bent legs. The staple and pledget assembly includes the staple and a pledget configured to receive the pair of legs of the staple. The pledget comprises a bioabsorbable material. The pledget is configured to advance distal ends of the pair of legs to a position in which the distal ends are laterally offset from a plane in which the crown of the staple is disposed.

The present application discloses surgical auxiliary equipment for sutureless closed skin incisions in the superficial fascia of the skin, comprising: a subcutaneous negative pressure drainage device comprising a catheter partially reaching into a preset depth of the inner cavity of the subcutaneous incision; an incision closing device arranged at the periphery of the skin incision; and a negative pressure device above skin arranged at the periphery of the skin incision and used for generating a negative pressure. Through the surgical auxiliary equipment of the present application, the sutureless closure of full-thickness tissues above the deep fascia of the skin can be achieved, so as to avoid transverse scars on the surface of the skin caused by suture oppression and cutting, and no suture knots are left in superficial fascia, so as to eliminate an important factor causing bacterial colonization and a main inducement leading to relapse of incision infection.

Systems, devices and methods described herein relate to endovascular devices for delivering sutures for securing grafts or other objects to patient vessels. In some embodiments, a suture includes a set of two legs having proximal ends joined to each other and elongate bodies that extend parallel to one another such that the set of two legs form a U-shaped structure. A suture delivery system can include a housing configured to contain a suture in a flattened configuration, and a deployment element having a ribbon-shaped distal portion disposed in the housing and including a set of formations, where the housing and the set of formations of the deployment element are configured to collectively constrain the suture in the flattened configuration until the suture is released through the opening of the housing.

A staple apparatus can include a base member substantially coplanar to a first axis and a second axis perpendicular to the first axis. The base member can include a trapezoidal shape including two substantially equal length sides and two unequal length sides, the two unequal length sides comprising a first side and a second side with the first side being shorter than the second side and the first side being parallel with the second side on the first axis. The base member can include an aperture passing through a center point of the base member, a first indentation in the first side, and a second indentation in the second side. The staple apparatus can include a first pair of legs protruding from the first side of the base member and a second pair of legs protruding from the second side of the base member.

Devices, systems, and methods for heart-valve annulus repair techniques, comprising a reinforcing device with one or both of a heating mechanism or clamping mechanism. The heating mechanism may function by heating a localized portion of the annulus so as to reduce the circumference of the annulus and/or increase the stiffness of the tissue. The clamping mechanism may function by gathering or pinching an area of tissue to then reduce the circumference of the annulus and/or increase the stiffness of the tissue.

A multi-staple inserter and drill guide, and methods of use thereof, are disclosed therein. The orthopedic staples can also be used in addition to interfragmentary screws to apply further compression of the bone fragments.

The present disclosure provides staples, and corresponding staple guides, for applying a compressive force between biological elements. The staples may include a bridge portion and a pair of tines extending from the bridge portion configured for implantation into biological elements. The tines may be spaced a first distance in a first state of the bridge portion. The bridge portion may be elastically deformable into a second state with the pair of tines spaced a second distance that is greater than the first distance and the tines pre-loaded to apply a compressive force therebetween. The guides may include a staple engagement portion operable to maintain the biased state of the staple, and/or a drill guide portion operable to facilitate the formation of apertures spaced the second distance in the biological elements.

A tissue-fastening tool indwelling system includes: a sheath; a needle tube disposed in the sheath; a tissue-fastening tool including a wire having a coil region disposable in the needle tube in a stretched state and restorable to a coil shape with the same winding diameter outside the needle tube; a stylet connected to the wire; and a manipulation part for manipulating the stylet to advance the wire and rotate the sheath in a first direction. In a state where a distal end of the needle tube is proximal of the distal end of the sheath, the manipulation part is designed to operate such that the wire is delivered from the sheath by a length of one winding of the coil region per rotation of the sheath by less than one turn, and the protruding coil region biased to have a diameter larger than the winding diameter.
