  • Publication number: 20130281783
    Abstract: A laparoscopic port assembly includes a cannula unit including three cannulas each extending at an acute angle relative to a base. The cannulas are flexible for receiving respective angulated laparoscopic instruments. The cannula unit is rotatingly received in a port holder for rotation about a longitudinal axis of the holder, the holder being disposable in an opening in a patient's skin.

  • Patent number: 8562641
    Abstract: Laparoscopic instruments and trocars are provided for performing laparoscopic procedures entirely through the umbilicus. A generally C-shaped trocar provides increased work space between the hands of the surgeon as well as S-shaped laparoscopic instruments placed through the trocar when laparoscopic instrument-trocar units are placed through the umbilicus. In order to facilitate retraction of intra-abdominal structures during a laparoscopic procedure, an angulated needle and thread with either one- or two sharp ends is provided. Alternatively, an inflatable unit having at least one generally C-shaped trocar incorporated within the unit's walls can be placed through the umbilicus following a single incision. Generally S-shaped laparoscopic instruments may be placed through the generally C-shaped trocars to facilitate access to intra-abdominal structures.

  • Publication number: 20130274553
    Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally-invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly-expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be asymmetric around a stabilizer subsystem to maximize space for a tool and an endoscope to each be maneuvered independently to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.

  • Patent number: 8506479
    Abstract: Exemplary embodiments of devices and method for affecting at least one anatomical tissue can be provided. A configuration can be provided that includes a structure which is expandable (i) having and/or (ii) forming at least one opening or a working space through which the anatomical tissue(s) is placed in the structure. For example, the structure, prior to being expanding, can have at least one partially rigid portion. In addition, or as an alternative, upon a partial or complete expansion thereof, the structure can be controllable to have a plurality of shapes. Further, the structure can be controllable to provide the working space with multiple shapes and/or multiple sizes.

  • Patent number: 8430808
    Abstract: A surgical instrument includes a hollow member having a sidewall provided with a window and a closure member movably connected to the hollow member for alternately covering and uncovering the window. The hollow member has a first clamping surface along an edge of the window, while the closure member has a second clamping surface opposing the first clamping surface and disposable substantially adjacent thereto in a clamping or closure configuration of the instrument. The instrument additionally comprises a tissue occlusion component mounted to at least one of the hollow member and the closure member for acting on tissues gripped between the first clamping surface and the second clamping surface, to couple the tissues to each other.
