Patent number: 8777961Abstract: A surgical retrieval apparatus includes a housing having an elongated sleeve extending therefrom that, together, cooperate to define a lumen extending therethrough. A shaft having an end effector assembly disposed at a distal end thereof is selectively translatable between a first position, wherein the end effector assembly is disposed within the sleeve, and a second position, wherein the end effector assembly extends distally from the sleeve. A specimen retrieval bag is releasably coupled to the end effector assembly and is deployable to an extended position upon movement of the end effector assembly from the first to the second position.Type: GrantFiled: September 19, 2011Date of Patent: July 15, 2014Assignee: Covidien LPInventors: Ramiro Cabrera, Alistair Fleming, Simon Roderick Grover, Charles Alan Seegert

Patent number: 8652151Abstract: A right angle clip applier apparatus including a distal clip applying mechanism and a proximal advancing mechanism positioned in a handle assembly. The clip applying mechanism includes a feed rod interfacing with a cartridge for the advancing and applying of clips on tissue portions. A plurality of clips are enclosed in the apparatus. The advancing mechanism is actuated by a lever in the handle assembly which creates a drive force that repositions the feed rod and clips. Each actuation of the lever applies a first clip and advances clips to a new position in a distal direction. The clip applying mechanism can be utilized at any angle and can be rotated through 360 degrees while holding the handle in a fixed position. An empty clip indicator is provided.Type: GrantFiled: January 13, 2011Date of Patent: February 18, 2014Assignee: Covidien LPInventors: Adam Lehman, Gene Stellon, Ramiro Cabrera, Ralph A. Stearns

Patent number: 8636752Abstract: An endoscopic stitching device including a tool assembly having a pair of juxtaposed jaws; a rotatably supported camming hub defining a groove formed in an inner surface of a central lumen thereof; and a center rod slidably and rotatably disposed within the lumen of the camming hub. The center rod is operatively engaged with the groove formed in the camming hub and engaged with the pair of jaws. The inner groove of the camming hub is configured such that, in at least one position, axial translation of the center rod relative to the camming hub results in rotation of the camming hub and at least one of opening and closing of the pair of jaws. The inner groove of the camming hub is configured such that, in at least one other position, rotation of the canter rod results in rotation of the tool assembly.Type: GrantFiled: April 23, 2012Date of Patent: January 28, 2014Assignee: Covidien LPInventors: Ramiro Cabrera, Eric J.
