Patent number: 11191673Abstract: 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.Type: GrantFiled: February 21, 2017Date of Patent: December 7, 2021Assignee: Covidien LPInventors: Timothy Sargeant, Arpan Desai, Joshua Stopek, Atu Agawu, Saumya Banerjee, Frank Viola
