  • Patent number: 7731652
    Abstract: A medical device for allowing a physician to unhand a scope or other instruments while maintaining control of the scope or other instruments during a medical procedure. The medical device includes at least one docks and a harness for attaching the dock to the physician's body. The harness can be adjustable, or sized to fit a specific physician. During a procedure, a physician outfitted with the medical device can place a scope and/or other instrument in the dock(s). Once the scope and/or other instrument is placed in the dock(s), the physicians hands are free to perform other procedures, while the physician continually controls the relative position of the scope with respect to the physician or the patient.

  • Publication number: 20100121140
    Abstract: Medical systems, devices and methods are disclosed for suturing a perforation in tissue, that may be employed endoscopically and/or laparoscopically, and that offer simple, reliable and controllable placement of suture around a perforation for complete closure thereof. One embodiment of the medical device generally includes an endcap for use with an endoscope to suture an opening in tissue using a tissue anchor. The endcap has a tubular shape defined by an annular sidewall, and the sidewall defines an interior space. A side port is further defined by the annular sidewall and is in communication with the interior space. The side port is sized to receive and locate the tissue within the interior space for suturing. A support rib is positioned within the interior space and distal to the side port. The support rib and sidewall define a piercing aperture therebetween that supports the tissue being sutured.

  • Publication number: 20100087707
    Abstract: Medical systems, devices and methods are provided for manipulating tissue, such as for closing a perforation in an internal bodily lumen. One embodiment of a medical system generally includes an endoscope, an endcap attached to the distal end of the endoscope, a plurality of needles attached to the endcap, a stylet cap slidably disposed of the endcap, a plurality of stylets attached to the stylet cap, and a plurality of tissue devices. The plurality of needles define a plurality of needle lumens and the plurality of stylets project distally into the needle lumens. The plurality of tissue devices are positioned within the needle lumens, whereby translation of the stylet cap relative to the endcap causes the plurality of stylets to engage the plurality to tissue devices and eject them from the plurality of needles. The medical system may further include a protective tip slidably attached to the plurality of needles.

  • Publication number: 20100069924
    Abstract: The present embodiments provide methods for facilitating closure of a bodily opening. In one exemplary method, a compressive force is imposed upon first and second tissue segments that at least partially surround an opening in tissue. The first and second tissue segments are positioned in a manner where a first serosal tissue region of the first tissue segment is compressed against a second serosal tissue region of the second tissue segment to facilitate sealing of the opening. At least one tacking device having proximal and distal deployable members may be deployed using a suitable insertion tool to impose a compressive force to hold the first serosal tissue region in a sealing relationship against the second serosal tissue region.

  • Publication number: 20100069955
    Abstract: The present embodiments provide methods for facilitating closure of a bodily opening. In one exemplary method, at least a portion of a first tacking device is disposed through at least a portion of tissue at a first location in a vicinity of an opening in the tissue. Then, at least a portion of a second tacking device is disposed through at least a portion of tissue at a second location in the vicinity of an opening in the tissue. A closure member having at least one loop portion is advanced towards the first and second tacking devices, and the loop portion is positioned around at least a portion of the first tacking device and at least a portion of the second tacking device. The closure member then is actuated to urge the first tacking device towards the second tacking device to provide a compressive force upon the opening.
