  • Intra-operative heart size measuring tool
    Patent number: 9427318
    Abstract: A heart size measuring tool includes a tubular body, a flexible measuring cord having length indicia, a measuring cord support mechanism movable between retracted and extended states with respect to the body, and an actuating mechanism to move the measuring cord support mechanism. When in the retracted state the measuring cord support mechanism is positioned within the tubular body with the measuring cord in a collapsed position. When the measuring cord support mechanism is in the extended state the measuring cord extends around a portion of a heart to be measured. A scale on the body can be used in connection with the indicia on the measurement cord to provide a reading of the heart size.

    Abstract: Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

  • CRYOLIPOLYSIS DEVICES AND METHODS THEREFOR
    Publication number: 20160058956
    Abstract: Described herein are cryolipolysis devices, systems, and methods for facilitating percutaneous access to a target blood vessel by performing cryolipolysis on subcutaneous adipose tissue obscuring the target blood vessel (e.g., a vessel used for hemodialysis treatment). Generally, the devices include a cooling member carrying a coolant that cools a selected portion of adipose tissue overlying the target blood vessel to reduce the selected portion of adipose tissue, thereby forming a depression in the adipose tissue and allowing the target blood vessel closer to the surface of the skin. In some variations, the cooling member is placed subcutaneously to directly cool the selected portion of adipose tissue. In other variations, the cooling member is placed external to the patient to indirectly cool the selected portion of adipose tissue through the skin.
