Patent number: 9168040Abstract: Apparatus and methods for applying fasteners during endoscopic surgery are provided. The apparatus generally comprises a handle portion, a triggering mechanism and a fastener applicator. One embodiment of the invention forms the fastener around a single focal point on an anvil. Another embodiment vertically stacks the fasteners in a fastener applicator which is readily detachable from the handle portion by virtue of a rotational locking system and which may be replaced with a new fastener applicator having a fresh load of vertically stacked fasteners. The various embodiments may be variously combined together in a single device. The methods generally include the following steps: forming a fastener by placing it over a single focal point anvil and pressing the fastener against the single focal point anvil using a slide.Type: GrantFiled: December 19, 2011Date of Patent: October 27, 2015Inventors: Helmut L. Kayan, James E. Jervis

Patent number: 8187296Abstract: An apparatus for creating an anatomic space in tissue in a body comprises an introducer and a sheath. The tubular sheath may surround the introducer, and may have a weakened region along its longitudinal axis. A handle may be provided on the sheath. The handle may be adapted to be pulled proximally to separate the weakened region and allow the sheath to be removed from the introducer. The sheath may be secured to the introducer via detents or latches on the handle.Type: GrantFiled: October 22, 2007Date of Patent: May 29, 2012Assignee: Tyco Healthcare Group LPInventors: Maciej J.

Patent number: 7641094Abstract: Apparatus and method for applying fasteners during endoscopic surgery. The apparatus vertically stacks fasteners in a fastener applicator which is detachable and replaceable from a handle portion by a rotational locking system. The fasteners are applied by moving them to a driving channel by a biased fastener positioning spring as a slide is retracted; the slide is then advanced until it engages a fastener in the driving channel and drives the fastener over an anvil. During advancement of the slide a biased stop spring is forced back into a recess thereby allowing the next fastener to move forward in the storage channel; the slide is then retracted, freeing biased ejector springs to kick the formed fastener off the anvil; finally the slide is further retracted, until the fastener positioning spring is once again free to move the distal-most fastener from the storage channel into the driving channel.Type: GrantFiled: October 30, 2003Date of Patent: January 5, 2010Assignee: General Surgical Innovations, Inc.Inventors: Helmut L.
