  • Patent number: 9949733
    Abstract: An all-suture suture anchor system includes an all-suture anchor, an inserter, and a specially designed drill. The drill is used to enlarge the hole and create a pocket under the bone surface from the pre-drilled hole. The created pocket is intended to accommodate the expansion of the anchor when deployed into the bone, generating a true mechanical interference under the bone surface. The anchor is loaded on the inserter and placed at full length vertically inside the drilled hole. While holding the inserter on top of the drilled hole, so that a feature on the inserter keeps the anchor to a desired depth below the bone surface, tension is applied to the suture limb that is connected to the bottom end of the anchor. This tensioning step causes the length of the anchor to contract vertically and the anchor is simultaneously expanded circumferentially to fill the pocket previously created by the drill.

  • Patent number: 9539020
    Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The body comprises a pivotal trigger. The shaft couples the end effector and the body together. The end effector comprises a clamp arm and an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue. Pivotal movement of the trigger causes movement of the clamp arm. The shaft is operable to be selectively coupled and decoupled from the ultrasonic transducer. The apparatus comprises electro-mechanical means for coupling and decoupling the shaft from the ultrasonic transducer, and may further comprise means for preventing movement of the shaft as it is coupled to the ultrasonic transducer.

  • Patent number: 9539052
    Abstract: An apparatus treats tissue at or near a sphincter. The apparatus has an elongated member having at least one lumen including an inflation lumen, and a basket assembly including a first and a second arm. An inflatable member is coupled to the inflation lumen and has a deployed and a non-deployed state. In the deployed state, the inflatable member expands the basket assembly into contact with tissue. At least one of the first and second arms of the basket assembly has a fluid lumen having an aperture for conveying a fluid from the basket assembly. A source of fluid is coupled to the fluid lumen for conveyance of fluid through the aperture. The fluid can be, e.g., an electrolytic solution, and/or an anti-infection agent, and/or an echogenic media, and/or a steroid, and/or an anesthetic, and/or a medicament, and/or a tissue cooling agent. The source can be a drug delivery device.

  • Patent number: 9526401
    Abstract: Flow reduction hood systems are described which facilitate the visualization of tissue regions through a clear fluid. Such a system may include an imaging hood having one or more layers covering the distal opening and defines one or more apertures which control the infusion and controlled retention of the clearing fluid into the hood. In this manner, the amount of clearing fluid may be limited and the clarity of the imaging of the underlying tissue through the fluid within the hood may be maintained for relatively longer periods of time by inhibiting, delaying, or preventing the infusion of surrounding blood into the viewing field. The aperture size may be controlled to decrease or increase through selective inflation of the membrane or other mechanisms.

  • Patent number: 9498600
    Abstract: Described herein are atherectomy catheters, systems and methods that include a distal tip region that may be moved laterally so that its long axis is parallel with the long axis of the main catheter body axis. Displacing the distal tip region laterally out of the main catheter body axis exposes an annular blade and opens a passageway for cut tissue to enter a storage region within the catheter. The annular blade may be internally coupled to a drive shaft that rotates the blade, and thus the exposed blade edge may have the same crossing profile (OD) as the rest of the distal end region of the catheter. Also described herein are gear-driven atherectomy devices that may use a cable drive shaft to actuate the annular blade. Both push-to-cut and pull-to-cut variations are described, as are methods for cutting tissue and systems including these atherectomy catheters.
