  • Publication number: 20240382232
    Abstract: A loading tool for loading a biostimulator onto a biostimulator delivery system is described. The loading tool includes a first body portion and a second body portion connected by a hinge. A latch is mounted on the first body portion, and the latch can be locked to fasten the first body portion to the second body portion. A biostimulator can be mounted in the loading tool, and a tether of a biostimulator delivery system can be inserted through a funnel in the loading tool to engage the biostimulator. An operator can use only one hand to unlock the latch, open the loading tool, and remove the loading tool from the biostimulator prior to delivering the biostimulator into a patient. Other embodiments are also described and claimed.

  • Publication number: 20240278025
    Abstract: A biostimulator, such as a leadless cardiac pacemaker, having a flexible circuit assembly, is described. The flexible circuit assembly is contained within an electronics compartment between a battery, a housing, and a header assembly of the biostimulator. The flexible circuit assembly includes a flexible substrate that folds into a stacked configuration in which an electrical connector and an electronic component of the flexible circuit assembly are enfolded by the flexible substrate. An aperture is located in a fold region of the flexible substrate to allow a feedthrough pin of the header assembly to pass through the folded structure into electrical contact with the electrical connector. The electronic component can be a processor to control delivery of a pacing impulse through the feedthrough pin to a pacing tip. Other embodiments are also described and claimed.

  • 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.

  • Publication number: 20180055687
    Abstract: Catheter devices and methods for intravascular heating and/or cooling of human or veterinary patients. The catheter devices generally comprise catheters having inflow and outflow lumens and at least one curvilinear balloon connected to the inflow and outflow lumens such that heat exchange fluid may be circulated through the balloon(s). The catheter is inserted into the vasculature and heated or cooled fluid is circulated through the balloon(s) to heat or cool blood flowing in heat-exchange proximity to the balloon(s), thereby effecting heating or cooling of all or a portion of the patient's body.

  • Patent number: 9808617
    Abstract: An active implantable medical device is disclosed herein having a radio-opaque marker. The radio-opaque marker can be formed within an exterior wall of the device or within recesses on the outside of the exterior wall. The implantable medical device can be a leadless pacemaker. The shape of the radio-opaque marker can be designed to facilitate visualization and identification of the location, orientation, and rotation of the implanted medical device by conventional fluoroscopy. Methods of use are also disclosed.
