  • Patent number: 8617206
    Abstract: Biocompatible wound closure devices including an elongate body and a plug member are useful for wound repair. A wound closure device includes an elongate body defining a longitudinal axis and having a proximal end and a distal end, and a plug member having a tissue facing surface and including a first shaped section and a second shaped section, each of the first and second shaped sections having an abutment surface. The first and second shaped sections are movable about a hinge between a collapsed position in which the abutment surfaces extend away from the longitudinal axis of the elongate body and a deployed position in which the abutment surfaces abut and are substantially aligned with the longitudinal axis of the elongate body, the abutment surfaces controlling a deployed angle of the tissue facing surface of the plug member with respect to the elongate body.

  • Publication number: 20130245677
    Abstract: A surgical portal apparatus includes a sleeve having a proximal end and a distal end that extends along a longitudinal axis, and a surgical tape. The sleeve includes an inner wall defining an internal longitudinal passageway dimensioned for permitting passage of a surgical object therethrough and an outer wall configured for positioning against tissue. The inner and outer walls define at least a partial annular space therebetween, the annular space being in fluid communication with an opening in the outer wall. The surgical tape includes a body portion retained within the annular space of the sleeve and a leading tab extendable through the opening in the outer wall of the sleeve. The surgical tape has a first surface and a second surface, each of the first and second surfaces having at least one of tissue reactive functional groups and self-reactive functional groups.

  • Patent number: 8292846
    Abstract: An applicator tip for use with a fluid applicator includes a base configured for releasable engagement with a fluid applicator at a proximal end of the base. The base includes a chamber defined therein configured for retaining a mixing component therein. One or more penetrable members are disposed within the base to at least partially encloses the chamber to retain the mixing component therein. A shaft extends distally from the base and defines a longitudinal axis. The shaft has a lumen extending therethrough configured for passage of a fluid therethrough. Upon penetration of the penetrable member, fluid from the fluid applicator flows into the chamber such that the fluid and the mixing component form a mixture to be applied.

  • Publication number: 20120220827
    Abstract: A surgical instrument includes an elongated tubular member having a proximal end and a distal end. At least a portion of the elongated tubular member is resiliently deformable from an at-rest configuration. The elongated tubular member includes a camera assembly disposed therein. An outer shaft defining a lumen extending therethrough is positioned annularly about the elongated tubular member. At least one of the outer shaft and the elongated tubular member is moveable with respect to the other between a substantially overlapping position wherein the elongated tubular member is deformed to conform to the shape of the outer shaft, and a displaced position wherein at least a portion of the elongated tubular member extends distally from a distal end of the outer shaft. In the displaced position, the portion of the elongated tubular member extending from the outer shaft returns, or reforms back to the at-rest configuration.
