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

Patent number: 8834418Abstract: An applicator for use in tissue repair is provided. The applicator includes a base configured to dispense a material and an applicator tip operably connected to the base. The applicator tip includes a body having a distal end configured to engage a tissue defect and a mold disposed about the body configured to engage tissue about the tissue defect. The mold is configured to be selectively positioned about the distal end of the body between at least a first position and a second position to deposit material to form at least a first layer and a second layer. Also provided are applicator tips, methods and kits for tissue repair.Type: GrantFiled: June 13, 2011Date of Patent: September 16, 2014Assignee: Covidien LPInventors: Timothy Sargeant, Joshua Stopek, Arpan Desai, Atu Agawu, Saumya Banerjee

Patent number: 8617206Abstract: 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.Type: GrantFiled: October 4, 2010Date of Patent: December 31, 2013Assignee: Covidien LPInventors: Timothy Sargeant, Gregory Fischvogt, Michael Bettuchi, Gerald Hodgkinson, Joshua Stopek, Arpan Desai, Atu Agawu, Saumya Banerjee

Publication number: 20120220827Abstract: 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.Type: ApplicationFiled: February 7, 2012Publication date: August 30, 2012Inventors: Timothy Sargeant, Arpan Desai, Atu Agawu

Publication number: 20120108901Abstract: A surgical instrument includes an elongated tubular member defining a longitudinal axis and having a lumen extending therethrough. A light source is disposed within the elongated tubular member. The light source is configured to emit light from a distal end of the elongated tubular member. A mirror assembly is coupled to a distal end of the elongated tubular member. The mirror assembly is moveable between a retracted position and an extended position. In the retracted position, the mirror assembly is positioned adjacent an outer surface of the elongated tubular member. In the extended position, the mirror assembly extends distally from the elongated tubular member to re-direct light emitted by the light source.Type: ApplicationFiled: September 7, 2011Publication date: May 3, 2012Inventors: Timothy Sargeant, Arpan Desai, Atu Agawu
