  • Publication number: 20150094741
    Abstract: A suturing device includes an elongate shaft defining a longitudinal axis, a trajectory guide translatably mounted on the elongate shaft and an introducer guard member operatively coupled to a distal portion of the elongate shaft. The introducer guard member includes at least one arm member which is movable between a first position in which the arm member is retracted, substantially in alignment with the longitudinal axis and a second position in which the at least one arm member is deployed. The introducer guard member includes an attaching member for releasably retaining a suture. The trajectory guide defines at least one bore therethrough. The bore obliquely extends through the trajectory guide and defines an angle with respect to the longitudinal axis. The bore aligns with the attaching member when the introducer guard member is in the second position.

  • Patent number: 8968926
    Abstract: A biodegradable battery is provided. The battery includes an anode comprising a material including an inner surface and an outer surface, wherein electrochemical oxidation of the anode material results in the formation of a reaction product that is substantially non-toxic and a cathode comprising a material including an inner surface and an outer surface, the inner surface of the cathode being in direct physical contact with the inner surface of the anode, wherein electrochemical reduction of the cathode material results in the formation of a reaction product that is substantially non-toxic, and wherein the cathode material presents a larger standard reduction potential than the anode material.

  • Publication number: 20140203061
    Abstract: A surgical stapling apparatus includes a housing, an end effector, fasteners, and one or more surgical buttresses. The end effector is secured to the housing and has first and second jaw assemblies. The first jaw assembly defines slots and the second jaw assembly defines pockets. One or both of the first and second jaw assemblies define recesses. The fasteners are disposed in the slots of the first jaw assembly and are formed by the pockets of the second jaw assembly. The one or more surgical buttresses have a body that includes plugs that are integrally formed with the body for insertion into the recesses to secure the surgical buttress(es) to one or both of the first and second jaw assemblies. The body substantially overlies at least some of the slots of the first jaw assembly and/or at least some of the pockets of the second jaw assembly.

  • Publication number: 20140151431
    Abstract: A surgical stapling apparatus includes a housing and an end effector secured to the housing. The housing supports a knife assembly including a knife. The end effector has first and second jaw members. One or both of the first and second jaw members define a knife channel. The first jaw member defines fastener slots and the second jaw member defines fastener pockets. One or more of the knife channel, the fastener slots, and the fastener pockets includes lateral recesses. Fasteners are disposed in the fastener slots and formed by the fastener pockets. One or more surgical buttresses have a body that overlies one or both of the fastener slots and the fastener pockets. Portions of the body of the one or more surgical buttresses are disposed within the lateral recesses to secure the one or more surgical buttresses to one or both of the first jaw member and the second jaw member.
