Publication number: 20150359552Abstract: Surgical tools that can be used in single port laparoscopic procedures can include a low-profile handle assembly to minimize tool interference adjacent the incision site. For example, a handle assembly for a surgical instrument can have a generally in-line configuration extending linearly along a central longitudinal axis of an elongate shaft of the instrument. A linkage mechanism including a trigger, an actuation link, and an actuation shaft can be positioned within the in-line handle. The linkage mechanism can be pivoted between an open position in which end effectors of the instrument are open and a toggle position in which the end effectors are locked closed. A locking mechanism such as a ratchet mechanism can also be used to lock the end effectors. A surgical dissector can include gripping jaws having a curved profile or an angled elongate shaft to minimize tool interference and maximize visibility within a procedure site.Type: ApplicationFiled: August 24, 2015Publication date: December 17, 2015Inventors: Arkadiusz A. Strokosz, David T. Okihisa, Steven E. Decker, Phillip DeAlday, Scott V. Taylor, Henry Kahle

Publication number: 20150250486Abstract: A tissue retrieval system can include a tissue retrieval bag with an elongate profile. The tissue retrieval bag can have a relatively large volume, but be rollable to a stowed configuration to fit in a relatively small diameter introducer. The tissue retrieval system can include one or more support arms coupled to the tissue retrieval bag, the support arms biased to position the tissue retrieval bag in an access position once deployed from the introducer. A tissue retrieval system can have a hybrid tissue retrieval bag including material properties that vary along the depth of the bag from an open end to a closed end. A tissue retrieval bag can be used in conjunction with an introducer, or as a stand alone tissue retrieval bag.Type: ApplicationFiled: May 18, 2015Publication date: September 10, 2015Inventors: Scott V.

Publication number: 20150173792Abstract: A surgical access port or trocar is provided. The trocar has a trocar seal housing and a trocar cannula with an optical obturator insertable through the trocar seal housing and the trocar cannula. The trocar is configured to access a body cavity, to maintain positive pressure and to prevent loss of surgical insufflation gas used in laparoscopic procedures. The trocar seal housing can be releasably attached to the trocar cannula. The trocar seal housing may also have a shield and/or alignment channel that provide protection or assist in operation of instrument and zero seals housed in the trocar seal housing.Type: ApplicationFiled: March 3, 2015Publication date: June 25, 2015Inventors: Kimball B. McGinley, Henry Kahle, Scott V. Taylor, Gary M. Johnson

Publication number: 20150157304Abstract: A tissue retrieval system can contain and withdraw excised tissue specimens from within a body cavity. The tissue retrieval system can include a tissue retrieval bag, a foldable actuator, and an introducer. The foldable actuator can be foldable between an insertion configuration for placement through an access device without the aid of a grasper or applicator, and a deployed configuration for supporting the tissue retrieval bag in an open state. The actuator can have a foldable handle to facilitate withdrawal from the body cavity. After insertion of the tissue specimens into the retrieval bag, the retrieval bag is then cinched closed to prevent spillage of its contents and to prevent contamination of the body cavity and body cavity wall during withdrawal of the retrieval bag from within the body cavity.Type: ApplicationFiled: February 16, 2015Publication date: June 11, 2015Inventors: Scott V. Taylor, Henry Kahle

Publication number: 20150105728Abstract: The invention is directed to a bladeless trocar obturator to separate or divaricate body tissue during insertion through a body wall. In one aspect, the obturator of the invention comprises a shaft extending along an axis between a proximal end and a distal end; and a bladeless tip disposed at the distal end of the shaft and having a generally tapered configuration with an outer surface, the outer surface extending distally to a blunt point with a pair of side sections having a common shape and being separated by at least one intermediate section, wherein each of the side sections extends from the blunt point radially outwardly with progressive positions proximally along the axis, and the shaft is sized and configured to receive an optical instrument having a distal end to receive an image of the body tissue. With this aspect, the tapered configuration facilitates separation of different layers of the body tissue and provides proper alignment of the tip between the layers.Type: ApplicationFiled: December 16, 2014Publication date: April 16, 2015Inventors: Henry Kahle, Arkadiusz A.

Publication number: 20150018626Abstract: A surgical access device includes a seal housing and a roller disposed in the housing and defining a working channel. The roller may be stationary or moveable within the seal housing to form both a zero seal in the absence of an instrument, and an instrument seal in the presence of an instrument. Rotation of the roller is contemplated and low-friction surfaces are discussed to reduce instrument insertion forces. Multiple rollers, wiper elements, low-friction braid, pivoting elements and idler rollers are contemplated. The rollers will typically be formed of a gel material in order to facilitate the desired compliance, stretchability and elongation desired.Type: ApplicationFiled: October 1, 2014Publication date: January 15, 2015Inventors: Scott V.

Publication number: 20140296778Abstract: A steerable kink resistant access device is provided having an elongated body and a steerable portion; methods for manufacturing the kink resistant device are also provided. The access sheath has an outside diameter sufficiently small so that it may be inserted into a body cavity or conduit. The access sheath typically has two internal lumen, a first lumen sized and configured as an access to a surgical site and a second lumen sized and configured to contain a tensioning device that, when acted upon, will deflect the steerable portion. The tensioning device may be directly or remotely attached to an actuation device that operates to control the tensioning and loosening of the tensioning device.Type: ApplicationFiled: January 27, 2014Publication date: October 2, 2014Applicant: Applied Medical Resources CorporationInventors: Charles C.

Publication number: 20140249541Abstract: The tissue retrieval system deploys a tissue bag at the surgical site. The bag is supported by the system as tissue is placed within the bag and is closed to isolate the collected tissue and allow the bag and collected tissue to be removed from the body. The bag can be reopened and re-closed as desired through use of a guide bead and cord. The bead also facilitates removal of the collected tissue.Type: ApplicationFiled: May 12, 2014Publication date: September 4, 2014Applicant: Applied Medical Resources CorporationInventors: Henry Kahle, Gary M.
