  • Patent number: 9186130
    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.

  • Publication number: 20140058361
    Abstract: An ultrasonically pulsating high-pressure fluid jet coupled with a suction system serve as a tissue harvesting device. The pulsated fluid jet disrupts tissue, permitting both harvesting of cells for therapeutic delivery, and as a surgical dissector and aspirator, for liposuction, soft tissue dissection, etc. The jet is delivered to the target tissue through a cannula, coupled to an aspiration system. An ultrasonically actuated rod vibrates within the cannula engaging a nozzle, disrupting the fluid jet into droplets, permitting tuning of the jet to the resonant frequencies and impact pressures necessary to dissociate the target tissue. A suction recovery system may be separated or integrally formed with the fluid jet cannula, and is linked by a closed tubing system appropriate for sterilization and subsequent delivery of the harvested cells/tissues with or without growth factor or matrix addition for human re-implantation or for in vitro expansion for later re-implantation.

  • Patent number: 8641725
    Abstract: Compressed air dissector is a surgical dissector which is used in tumor dissection and excision phases in surgical branches and especially in neurosurgery and microsurgery. The problem at this point is removal of the tumoral tissue without damaging the adjacent normal tissue and the blood vessels feeding the normal tissue. Moreover, serious difficulties may be encounter in the dissection phase of the arachnoid matter in brain surgery. The occurring adhesions can easily be opened with the aid of the air dissector. This provides great convenience in aneurism surgery. The operation principle of the compressed air dissector is direction of the controlled, sterile compressed air (gas) to the brain parenchyma and removal of the dissected particles from the location with an aspirator system. In said system, the particles in the air are cleaned with a filter system. When the compressed air is directed to the tumor tissue it easily dissects and removes the tumor.

  • Patent number: 8262565
    Abstract: In the endoscope system 1, a tissue recovery device 3 that recovers tissue is directly mounted on an endoscope 2. The tissue recovery device 3 has a filter portion, and the filter portion is inserted so as to traverse the conduit of the suction conduit 20 that passes inside the endoscope operation portion 10. The suction conduit 20 opens to the distal end portion of the endoscope insertion portion 11, and the working channel 23 branches off from the branch portion 22 that is provided further on the distal end side than the insertion location of the tissue recovery device 3. With this endoscope system, it is possible to reduce operational burden of the operator with regard to the endoscope system that includes the tissue recovery device that recovers tissue.

  • Patent number: 8172772
    Abstract: A surgical instrument can be used to capture and retrieve tissue, or other specimens, from within the body of a patient through a single trocar port. The surgical instrument can include a grasper, wherein the grasper can be configured to capture a specimen, and a specimen retrieval bag, wherein the specimen retrieval bag can be configured to at least partially surround, or encapsulate, the captured specimen when the specimen retrieval bag is in a deployed position. In certain embodiments, the retrieval bag can be inverted as it is moved between undeployed and deployed positions. In various embodiments, the surgical instrument can further include a snare operably engaged with the specimen retrieval bag, wherein the snare can be configured to at least partially close the bag. A vacuum can be placed in communication with the bag to reduce the size of the bag before it is removed from the surgical site.
