  • Patent number: 10154851
    Abstract: Provided herein are expandable endoscopic devices. In accordance with certain aspects of an embodiment of the invention, an endoscopic expandable device is disclosed that comprises an expandable jaw at the distal tip, a control wire connected to the jaw, a sheath enclosing the control wire, and a handle connected to the sheath or wire having an actuating trigger. The expandable jaw is configured to allow its delivery in a retracted configuration to a target site within a patient's body through the working channel of an endoscope, after which the jaw may reconfigure to an expanded configuration that is larger than the retracted configuration. This allows the expandable jaw to be easily delivered to the target site while allowing an operable jaw size that is larger than would be allowed if limited to size of the working channel.

  • Patent number: 10130347
    Abstract: The present invention advantageously provides devices, systems, and methods for percutaneous access and closure of vascular puncture sites. In an embodiment, the device for enhancing the hemostasis of a puncture site in a body lumen or tract comprises a catheter having one tubular member having a proximal end and a distal end with one inner lumen extending between at least a longitudinal portion of the catheter tubular member. The one tubular member includes external and internal tubular bodies each having proximal and distal ends. At least one of the external and the internal tubular bodies is longitudinally movable with respect to the other. An expansible member with proximal and distal ends is disposed on the distal end of the one tubular member. The distal end of the expansible member is connected to the distal end of internal tubular body and with its proximal end connected to the distal end of external tubular body.

  • Patent number: 10076349
    Abstract: An ultrasonic surgical drill or drill bit includes a tubular member having a longitudinal axis of symmetry and a plurality of fins extending in longitudinal planes each containing the axis. In a surgical method utilizing the drill bit, one places a distal tip of the drill bit in contact with bone, presses the drill bit against the bone, and during that pressing of the drill bit, conducts ultrasonic vibrations into the drill bit. With the fins in contact with the bone, the drill bit is oscillated or angularly reciprocated about a longitudinal axis, so that the fins fragment bone material located between the fins.

  • Patent number: RE48485
    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.
