  • Patent number: 9848870
    Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.

  • Patent number: 9844395
    Abstract: A device for retrieval of a vena cava filter is provided. The retrieval device has, approximately, an umbrella shape and consists of a central shaft; a plurality of frame struts, attached to frame strut attachment points on the central shaft and disposed radially about the central shaft; and a plurality of snare wires. The retrieval device has a collapsed configuration for insertion and removal from a blood vessel of a patient and an expanded state for capturing an intravascular filter in the blood vessel of the patient. The plurality of snare wires provides multiple points at which a vena cava filter, particularly one that has become misaligned during deployment or treatment, can be caught. The frame struts can be substantially sinusoidal in shape and made of shape memory metal, such as Nitinol. The snare wires can be made of a biocompatible material such as silk, polyester, polypropylene, or nylon.

  • Patent number: 9821113
    Abstract: An infusion set adapted to be secured to a skin surface includes a fixed base member connectable to the skin surface and a movable member. A needle or cannula is connected to the movable member and movable relative to the fixed base member. The movable member is movable from a first position in which the needle or cannula is not exposed externally of the fixed base member to a second position in which the needle or cannula is exposed externally of the fixed base member. A release member retains the movable member in the first position. Removal of the release member allows movement of the movable slide member to the second position.

  • Patent number: 9770318
    Abstract: An embolic protection device for use in a patient's blood vessel, such as the aorta, has an approximately cylindrical outer structure made of a filter mesh material and an approximately conical inner structure also made of a filter mesh material. On the downstream end of the embolic protection device, the wider end of the conical inner structure is joined to the cylindrical outer structure. The upstream end of the embolic protection device is open for blood to flow between the conical inner structure and the cylindrical outer structure. The space between the conical inner structure and the cylindrical outer structure defines a collection chamber for captured emboli. The narrow upstream end of the conical inner structure has a catheter port with a resilient seal that is sized for passage of a catheter shaft. The filter mesh material may be self-supporting or it may be supported on a resilient-framework or an inflatable framework.

  • Patent number: 9462802
    Abstract: Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.
