  • Publication number: 20220096076
    Abstract: Delivery systems, methods and associated devices for management of an elongate element having sections with differing mechanical properties, in particular, for management of a loop of suture-wire element extending proximally from a delivery catheter for deployment of a heart implant. Such management devices can include an inner feature (e.g. outward facing groove or series of tabs) along an inner circle about which a suture can be coiled and an outer feature (e.g. inward facing groove or tabs) to engage and constrain a wire section having increased stiffness within a coil having a larger diameter than the coiled suture. Such devices can be provided separately or can be integrated within a handle of the delivery catheter. Methods of loading suture-wire management devices and utilizing such devices during deployment of an implantable anchor are also described herein.

  • Publication number: 20220039957
    Abstract: Delivery systems, methods and associated devices to facilitate delivery and deployment of a heart implant. Such delivery systems and methods of delivery include use of a pair of magnetic catheters, including an anchor delivery catheter carrying an anchor, which can be stacked with or can be axially offset from the magnetic head. Such systems further include use of a puncturing guidewire advanceable through the magnetic head of the anchor delivery catheter to establish access to a chamber of a heart and which is attached to a bridging element such that continued advancement of the guidewire draws a bridging element attached to the first anchor across the chamber of the heart while the bridging element remains covered by the magnetically coupled catheters. Methods and devices herein also allow for cutting and removal of a bridge element of a deployed heart implant.

  • Publication number: 20210361427
    Abstract: Implants or systems of implants and methods apply a selected force vector or a selected combination of force vectors within or across the right atrium, which allow tricuspid valve leaflets to better coapt.

  • Publication number: 20210022864
    Abstract: Anchors for securing an implant within a body organ and/or reshaping a body organ are provided herein. Anchors are configured for deployment in a body lumen or vasculature of the patient that are curved or conformable to accommodate anatomy of the patient. Such anchors can include deformable or collapsible structures upon tensioning of a bridging element in a lateral direction, or segmented tubes that can be adjusted by tightening of one or more tethers extending therethrough. Such anchors can be used as a posterior anchor in a blood vessel in implant systems having a tensioned bridging element extending between the posterior anchor and an anterior anchor deployed at another location within or along the body organ. Methods of deploying such anchors and use of multiple anchors or multiple bridging elements to a single anchor are also provided.

  • Patent number: 10369044
    Abstract: A method for treating acute coronary syndromes (i.e., unstable angina or non-Q-wave MI) or transient ischemic attacks in a human or animal patient by placing a heat exchange apparatus in the patient=s vasculature and using that heat exchange apparatus to cool the patient to a temperature (e.g. 30-36 degrees C.) at which platelet inhibition (i.e., inhibition of platelet activation and/or aggregation and/or adhesion) occurs. Anti-shivering drugs or anesthesia may be administered to patients whose body temperature is cooled below that patient=s shivering threshold (typically approximately 35.5 degrees C.). If it is determined that platelet inhibition is no longer desirable, such as when the patient is about to undergo a surgical or interventional procedure wherein bleeding could be problematic, the hypothermia-induced platelet inhibition may be rapidly reversed by using the intravascular heat exchange apparatus to re-warm the patient=s body to normothermia or near normothermia.

  • Publication number: 20190083300
    Abstract: Methods and apparatuses for temperature modification of a patient, or selected regions thereof, including an induced state of hypothermia. The temperature modification is accomplished using an in-dwelling heat exchange catheter within which a fluid heat exchange medium circulates. A heat exchange cassette of any one of several disclosed variations is attached to the circulatory conduits of the catheter, the heat exchange cassette being sized to engage a cavity within one of various described re-usable control units. The control units include a heater/cooler device, a user input device, and a processor connected to receive input from various sensors around the body and the system. The heater/cooler device may be thermoelectric to enable both heating and 15? cooling based on polarity. A temperature control scheme for ramping the body temperature up or down without overshoot is provided.
