The collar member selectively secures the shell member to the adapter assembly.

Abstract: The present disclosure provides annular support structures for use in conjunction with stapling devices. These annular support structures may be suitable for reducing occurrences of leaking, bleeding and/or stricture, as well as anastomotic tension, when anastomosing various body structures.

Abstract: Biocompatible wound closure devices including an elongate body and a plug member are useful for wound repair.

Abstract: A surgical system comprising a cannula assembly and an obturator assembly for penetrating tissue is disclosed. A cover of the cannula assembly is mounted to a cannula housing and has a cover aperture therethrough. The cover has a trailing end face defining a predetermined geometrical configuration, at least a portion of the trailing end face is obliquely arranged relative to a longitudinal axis and terminates in, and leads toward the cover aperture to facilitate guiding of the surgical object through the cover aperture. The obturator assembly includes an obturator housing and an obturator member. The obturator housing has a housing base defining a leading end face, which defines a predetermined geometrical configuration corresponding to the predetermined geometrical configuration of the trailing end face of the cover to mate therewith upon assembly of the obturator assembly with the cannula assembly.

Abstract: A surgical stapling instrument is provided having systems for securing buttress material to the anvil and staple containing cartridge associated with the surgical instrument. The system includes a retainer configured to engage the anvil or the staple containing cartridge and capture the buttress material between the retainer and the anvil or staple containing cartridge. The disclose retainer engages the anvil or staple containing cartridge in snap fit or friction fit fashion. The buttress material includes a circumferential perforation line enabling the center of the buttress material to be stapled to tissue while the remainder of the buttress material remains with the anvil or staple containing cartridge.

Abstract: A resorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion. The resorbable screw fastener is 100% resorbed in vivo during a period of time ranging from about 14 days to about one year after implantation.

Abstract: The present disclosure provides structures and/or gaskets for deposition between adjacent intestinal sections in an anastomosis procedure. The structure possesses at least an inner ring of a first material, and a middle ring of a second material. The first material and the second material include a wound treatment material consisting of at least one of an adhesive, a sealant and/or a medicament. The first material is different from the second material.

Abstract: The present disclosure relates to a valve or seal of the type adapted to allow the introduction of an instrument or object therethrough. In particular, the valve disclosed herein is adapted to maintain a substantially fluid-tight seal with a surgical instrument and is used during a minimally invasive surgical procedure. The valve disclosed herein incorporates one or more bladder members adapted to retain a fluid therein that are associated by one or more interstitial members.

Abstract: A surgical system comprising a cannula assembly and an obturator assembly for penetrating tissue is disclosed. A cover of the cannula assembly is mounted to a cannula housing and has a cover aperture therethrough. The cover has a trailing end face defining a predetermined geometrical configuration, at least a portion of the trailing end face is obliquely arranged relative to a longitudinal axis and terminates in, and leads toward the cover aperture to facilitate guiding of the surgical object through the cover aperture. The obturator assembly includes an obturator housing and an obturator member. The obturator housing has a housing base defining a leading end face, which defines a predetermined geometrical configuration corresponding to the predetermined geometrical configuration of the trailing end face of the cover to mate therewith upon assembly of the obturator assembly with the cannula assembly.

Abstract: An access assembly includes a housing defining a longitudinal axis and having a longitudinal opening therethrough, a cannula extending distally from the housing and in fluid communication with the longitudinal opening and a seal member mounted within the longitudinal opening of the housing. The seal member is configured to receive an instrument therethrough in substantial sealed relation therewith. The housing is adapted to move in at least a radial direction with respect to the longitudinal axis whereby the seal member maintains the substantial sealed relation relative to the instrument as the instrument in manipulated. The housing may be flexible and capable of deflection relative to the longitudinal axis. The housing may comprise an elastomeric material in whole or in part. The seal member may be integrally formed with the housing. The housing may include at least one flexible ring portion and possibly a plurality of ring portions.

Abstract: A resorbable screw fastener and a method of firing with an applicator capable of applying a surgical fastener to tissue in order to form tissue connection to secure objects to tissue, the fastener including a body portion having a helical thread, a head portion disposed at the proximal end of the body portion.
